We are pleased to announce a new feature of Darluck natural cosmetics.

Our history has been a constant search for quality. Quality that meets the needs of our customers and delight. Through innovations and solutions in the products have achieved the quality targets.

Our concern from the beginning, besides quality, was also to sustainability. A biodegradable natural product could not come wrapped in a synthetic packaging. Then chose the natural polymer cellulose and recycled paper to pack our soaps.

With the growth we saw the opportunity to be innovating in this craft sector in question that packaging, and we decided that Darluck would then be a pioneer, as in other respects, the use of a simpler packaging and more in line with sustainability.

We developed a charming box to pack our soaps!
Everything is done for us, we maximize the handmade concept with great taste and creativity. We do not use any graphic or cardboarder to make these packages. We prepare the layout, buy recycled paper, printed, cut and assemble one by one these boxes.
Minimize the number of materials, we decrease the disposal, we use less resources and energy – nature thanks!

Natural cosmetics – release!

Posted on by

P1030836It is with great satisfaction that after six months of development and testing, I am launching an initial line of cosmetics – Cream Moisturizing Body, Moisturizing Cream for Hands and Face Lotion.

Are all natural vegetable products, free of any petrochemical derivative and that would surely be certified as natural by any cosmetics certifying bodies with global presence.

The difficulty of developing a line of products of this type here in Brazil, artisanal scale, the availability and quality of raw materials. It is very difficult to obtain the principal components and cosmetic actives for quality and reliability. Much time was spent in search of suitable raw materials and that would meet the development objective of cosmetic products. dimensoes cosmeticos verde tituloThe objectives established for product development were based on the dimensions that are used routinely to measure the efficiency and effectiveness of a cosmetic. This can be measured on 6 fundamental properties – nutrition, protection, penetration, slip application and oiliness. The goal is to achieve the maximum in the first five properties and the minimum in oily. I believe that I achieved this goal through careful choice of oils, cosmetic active and emulsifying system, developing three products 100% natural, free of any petroleum product. P1030823 P1030825 P1030827

Shaving soap – sandal

In the classic shaving many prefer shaving soap to shaving cream. The shaving soap requires a little more work to load the brush and build the lather. This time spent is part of the ritual of the classic shaving and refers to the golden age of the great barber.

Soap reuse/reprocessing – rebatch

Posted on by

P1030713

Accumulated over time a lot of soaps that were leaning awaiting a destination, and now decided to make a reuse – rebatch and donate the soap for some institutions.

He had a box full of them, most packaged in cellophane made ​​in 2009 that ended up not trading at the time I was selling soap, because I changed the formula to a harder soap and they ended up getting.

P1030674P1030677

The amazing thing is that these soaps with almost 5 years, were all perfect, even with a sharp aroma of essential oils. I gathered these samples retention of batches produced, some of the tests I ran, totaling 13 kg of soap.

First step is to break up the soap bars to facilitate melting. I tried with a electric meat grinder but did not work because most of this soap has a predominant, although very dry, composition of unsaturated oils (olive) and so sticky that does not flow through the grinder.

P1030686

The alternative was to manually grate, a work bordering on insanity that took almost a whole day to grate bar for bars, 13kg of soap.

P1030694

I used a slow-cooker (crock pot) to melt and fuse the soap into a single mass. I made 2,5 kg batch with addition of 10% water.

P1030700

As the grated soap occupies too much volume each batch of 2.5 kg was born at three stages, taking approx. 3 hours each processing. The last load of shavings was allowed to melt partially to give this effect of colored chips.

P1030698P1030702

Finally after almost a day scraping the soaps and another 15 hours of rebatching work, here are the 100 bars of soap 90g reprocessed.

Used oil soap – calcium carbonate

Posted on by

 

P1030287Rev Titulo EnI noticed that some initiatives of reusing used oil with the production of soap, both individual entrepreneurship as NGOs, using calcium carbonate or dolomite – ore of calcium carbonate and magnesium.

I was curious because the addition of such charges levied on the product costs and only justified if it had a very specific function. Ask information and how no one answered, I decided to do some tests.

used oil soap caco3 en

The formula used was this. The water based dye blue dye was used for better visualization of the test.P1030290titulo En To measure the difference in hardness of the soap was improvised device this mimics an apparatus for measuring impact. Consists of a driver tube, 1 meter high which is released by a steel rod with 15g weight. Gravity this rod goes through the driver tube and penetrates into soap. The hardness is measured by penetration depth (mm).

impacto

The soap was drying for 25 days before hardness test and both with and without carbonate, had the same hardness value of 6 mm.

P1030303

The foaming test was done with a shaving brush rubbed in a standard way to develop the soap foam. Not noticed any difference. The behavior of the wet soap was also identical, forming the “gooey” feature of this type of soap.

To test the oxidation (rancidity) of soap, they were left next to a glass window exposed to direct sun in the morning for 10 days.

P1030453text En

Significant difference, the soap with calcium carbonate has much better oxidation resistance.

Conclusion:
From what has been tested we can only say that calcium carbonate improves the oxidation resistance of this type of soap that is very prone to rancificar. I believe that this is not the main reason to use dolomite or calcium carbonate used in oil soap, but unfortunately was unable to have more elements that could justify its use. I also regret that the people who use this kind of load does not divulgem the merits of doing this, so that the costs justify the penalty, everyone would gain.

Healing soaps – neem, andiroba and copaíba oils

Posted on by

P1030481 text

The cold saponification, the cold process, is a simple and easy way to make soap, but it has its drawbacks. The incorporation of the additives, flavorings and active can only be done in the presence of caustic soda, i.e., all these components are present in the reaction environment of saponification of oils. This environment of strong alkalinity spares almost nothing, literally destroys many active principles of many components.

P1030493

There is a mistaken belief that the addition of the active at trace preserves this active from lye attack because in most trace lye has been consumed. Cheating in trace only about 10% of lye was consumed to form the emulsion (trace), the rest is still there and will react the same way. The concept of superfatting (SF) is also mistaken when they think that particular oil usually a noble oil will stay intact inside the soap. What happens if there is an excess of oil (or lye reducyion) which is the end of the saponification will be a mixture of oils that are part of the composition of oils of the formula and not the one that was added in the given trace.

P1030496 textP1030500Thus is pretty pointless proclaim certain sayings of effectiveness, for example, therapeutic soaps made with medicinal oils like Neem oil made ​​by cold process. Components of Neem after saponification not already exists, will exist sodium salts of palmitic, stearic, oleic and linoleic fatty acid, almost invariable composition of vegetable oils. One might argue, for example in this case Neem that certain components do not react with soda and remain intact but it lacks scientific evidence, whether because the unsaponifiable Neem is zero.

P1030502P1030508

The best way in such cases is to change the process of cold process for hot process. In the hot process of adding assets is made at the end of the hot saponification which fully preserves the components.

P1030510P1030512

That’s what was done with these three healing soaps with medicated oils – Neem (Azadirachta indica), Andiroba (carapa guianensis, Meliaceae) and Copaíba (Copaifera spp., Leguminosas)

P1030513

The basic formula is: olive / palm kernel / palm / castor – 45/25/25/5 a zero SF, lye concentration of 30% and 7% o/o of medicinal oils. Aroma, Neem – leaf cedar and citronella, Andiroba – citronella, patchouli and petigrain and Copaiba – estageriana Eucalyptus globulus and Eucalyptus

P1030517

The therapeutic properties of these oils are:  Neeem oil  – antifungus, antibacterial, antiviral and dermatological insecticide
Andiroba oil – anti-inflammatory, healing and antibugs, strengthener of the hair Copaiba Resin Oil – anti-inflammatory, healing, antibacterial

The process used was the Hot Process with Continuous Stirring – HPCS.

Hot Process Continuous Stirring – HPCS

Posted on by

P1030374

In the small town of Fontevraud L’Abbaye in the Loire Valley in France, since 1974 there is a renowned handmade soapmaker, Savonnerie Martin de Candre. Since its founding 40 years, Martin de Candre soap manufacture (MdC) is dedicated to producing excellent quality handmade soap products, as they say, using the classic process of Marseilles soap.

The soap (cream) shaving of Martin de Candre is considered the best in the world, they have a line of Marseille soap (for cleaning) with olive, coconut and palm, a line call huile de palme that is made with olive , coconut and palm oil and a third, huile d’olive, only with olive and coconut.

All these products have a premium price ranging 9 to 16 euros for soaps bars and shaving soap can cost 23 euros one container of 50 grams.

They claim that make the process of Marseilles soap which is a full boiling process where the soap is rinsed with salted water and glycerin is removed. In reality MdC makes a fairly conventional handmade hot process, which uses a mechanical stirrer to stir the mass during saponification and the lot size is less than 25 kg. This can be seen in the few photos on their website and also a video report produced by a French TV.

But what caught my attention was the procedure them to dry for eight months the soap bars and for 5 months the shaving soap! Intriguing because the hot process soap has saponified out and therefore safe and drying 15 days is enough to have the necessary hardness for lasting use. A soap made by Cold Process is ready for use in about 20 days. Here comes the question, why make a process more complex, lengthy and expensive process that is hot, if I can make cold process much simpler, faster and cheaper? After leaving it for 8 months a soap made ​​by hot or cold, theoretically they would have the same performance. It is clear that the hot process has the advantage of being able to incorporate sensitive components after alkaline saponification, which preserves these components, in which process cold is not possible.

I decided to design a test to compare the properties of a soap made by cold process and the same made by hot process and also compare the influence it has drying time in soap performance in both cases.

Hot Process with Continuous Stirring – HPCS

A handmade hot processs is normally done using as source of heating a double boiler or an electric slow cooker (crock pot), and the mass is homogenized manually from time to time to enable a comprehensive saponification.

To keep the process more akin to the Martin de Candre hot process, I designed a system called Hot Process Continuous Stirring – HPCS. Obviously not is an innovation, but in the artisanal scale not seen anyone use a similar system.
Thus, a comparative test between soaps produced by two distinct processes, eventually drifting to the development of a third way to do a hot process that is the HPCS.

P1030403rev

This is the setup of the equipment to do the HPCS – an electric heater (this is a laboratory magnetic stirrer), a mechanical stirrer (used with digital speed control) and a digital thermometer.

Here’s a video I made showing the HPCS to make benzoim soap (12 minutes):

Soaps Testing

The Martin Candre in your palm line has a honey soap and a benzoim (tonkinense Styrax) soap, and were made simlilar these for testing. The oil soap composition was: olive / palm kernel / palm – 60/25/15, SF 5% and lye concentration of 30%. The comparative test will be done with the honey and the benzoim was done to confirm and optimize the process HPCS. You can not make a regular cold process with benzoim because of the need to dilute the benzoim oil resin with ethanol, which would give the defect of seizing on mass.

Whipped soap

Posted on by

 

P1030182P1030183

In 2007 a soapmaker named Nizzy (Terry Nisbet) of Australia, popularized a different way of making soap, which is to hit solid oils in a kitchen blender, the same these for cakes or beat the whipped cream. The idea is incorporate air in the mass of saturated oil (solid), adding the unsaturated oils (liquid), add the lye and then the fragrances and additives. The process is a regular cold process done at room temperature and the difference is in phase to incorporate the air with an electric mixer.

The fundamental of the formulation is to have a proportion of at least 80% solids oils (saturated) which can be: palm, babassu, palm kernel oil, cocoa butter, shea butter, cupuacu, ucuúba, etc. and 20% of an unsaturated oil (liquid) to give the conditioning properties to the soap.

The whole process is done at room temperature or cooler, I usually make about 10 to 15 ° C . I melt solid oils to mix well and then put in the fridge to solidify. The important thing is to keep the oils solid, otherwise it is not possible to turn a beat aerated cream. This aeration causes this type of soap when placed in water, it not sinks, it floats. It also has a greater volume per weight due to occlusion of air. As the cold is done at a low temperature saponification is slow and hardly occurs and the gel phase. The air occluded also retards saponification and it allows more time to make soap. I often say that the hit soap is great because it does not need to rush, no haste, has no trace of the point, is the soap without stress!

OP Whipped Soap Blog english 520pxHere the formula and the instructions of the process.

P1030109

Clockwise, the pigments used as colorants, dispersed in 10g of vegetable glycerin, the mixture of essential oils, a 28% lye solution which was cooled to 10 ° C, the mixture of olive and castor oil and the plastic bag with the oils solids were melted and then kept for two hours in the fridge to solidify partially.

P1030111

The mixture of solid oils partially solidified.

P1030112

Beginning to incorporate air using a very simple mixer (made ​​in China) but cheap, versatile and robust, allows you to use one or two rods and can also be detached from the bracket and secure by hand, the planetary effect is obtained by rotating the bowl with the hands.

P1030118

After about 10 minutes beating on high speed aspect is that, like a cream.

P1030124

It is time to add the mixture of unsaturated oils slowly to avoid the decrease of the minimum aeration.

P1030127

The lye is added very slowly and with care to avoid splashing out of the container. If note the increased volume due to air occluded.

P1030128

After the addition of lye the mass is hit by another 10 minutes on average, it provides a good mix of lye with the oils and trace is not realize because of aeration.

Adds up the essential oil slowly to not damper the aeration

P1020987 Rev

After 3 weeks drying was completed the 100% coconut soap for use in the body. The question we had was whether this soap superfatting 20% to make him suitable for use in the body, neutralizing a possible effect of dry skin, was a really good soap for bath and body. I’ve used three days followed this soap in the shower and I can say that it is amazing, one the best soap I’ve ever made / used! It does not dry the skin, it leaves a feeling of treated skin with a cream or oil, velvety very nice. That’s because 20% of excess coconut oil is really a true superfatting. All other properties are excellent, has great hardness, and the bubble is fantastic! The essential oil massoia is very good, has a fabulous power of scent, smell fresh coconut! Each skin is a skin and not generalize, for me was very good, really enjoyed, you might not go so well in others, but in any case recommend making this soap.

Chocolate soap with mint and cocoa drops

The soap was decorated with the technique of straws with green pigment of chromium and titanium dioxide for green spots and aroma of 3% (o/o) of essential oil of peppermint. In the cocoa colored spots the red iron oxide was tinting with black iron oxide and titanium dioxide, and  to give aroma, was used sweet orange essential oil 2% (o/o).

IMG_0491Was made this device that eliminates the use of modeling clay to hold the straws. It measures the mold and is attached to the bottom of the mold. The wells are 8.5 mm in diameter to hold 8 mm straws and has a depth of 12 mm.

IMG_0650This mold was especially designed to allow to do 6 x 9 cm bars from 6 up to 24 bars  (130g) using the technique of pipes.

IMG_0653As this decoration was not used all the wells, those that are not used have been closed with tape (in blue).

IMG_0657The chocolate is mixed with oils and cocoa butter and melted in the microwave.

IMG_0660To use the technique of straws is important to leave a trace very light, which is added cocoa powder.

IMG_0663With the light trace is possible and even the mass of soap in the mold with the straws. The mold is in its maximum capacity as the mass is for 24 bars.

IMG_0664There was the formation of full gel and the surface temperature was 42 º C and after 6 hours the straws were removed when the temperature dropped to 32 º C.

IMG_0668Despite the high temperature generated by the gel phase, there were no problems with surface irregularities such as cracks. This mold format favors the full gel when used at maximum capacity. Decoration was made as described above, with the very light mass trace.

IMG_0669As mold lining was used a so-called opal plastic that is used to make lamps domes. Excellent plastic for this purpose.

100% Coconut soap – body & bath

Posted on by

IMG_0620IMG_0612Typically a soap with 100% coconut oil (coconut oil, palm kernel oil or babassu oil) is used for general cleaning, washing clothes or dishes, this because the excess sodium laurate is aggressive and sometimes irritating to the skin. As usually limited range of safe amount of coconut oil in 35% when the soap is used in the body.  The american soapmakers  found that a 100% coconut soap with a  superfatting of 20% or more ceases to be aggressive and provides a high quality soap for skin, loses its aggressiveness and being only with coconut, the bubble produces is  highly plentiful and enjoyable. This soap was made with 100% organic babassu oil, superfatting with 20%,lye concentration of 30% and was used as liquids 50% coconut milk and 50% coconut water, frozen, for the dilution of lye. Was used as fragrance essential oil of massoia (Cryptocarya massoia) that has an intense aroma of coconut, and a background of cinnamon. This oil is from Indonesia.

IMG_0579Coconut milk was mixed with coconut water and this mixture was frozen because I wanted to have minimal charring and maintain the color of soap as clear as possible. The lye was added to this frozen mixture and shaken until complete dissolution. After the dissolution temperature was 15 ° C.

IMG_0580The babassu oil was melted in the microwave and the temperature was at 54 º C.

IMG_0584In the mixture of lye solution and babassu oil, the temperature was 34 ° C, a good temperature to have a slight draw a gel and avoid too heavy. We used a wired whisk, it was not necessary to use the mixer. Was added in the light trace, 0.3% (o/o) of essential oil massoia.

IMG_0587The mold is made ​​of silicon and the straws are to obtain the decorative effect of the balls.
IMG_0594The straws were removed and the cavits were filled with blue coconut soap mass(ultramarine blue), after 6 hours, after full development of the gel, where the maximum temperature reached 38 ° C measured on the surface in the middle of the block.

IMG_0598IMG_0599The block was cut in half in the horizontal to generate four bars 9 x 7.5 cm 200g each.

Beautiful decoration … beautiful defect!

Posted on by

IMG_0569IMG_0566When did the dominoes soap, the first attempt was a failure. The sudden increase in viscosity after the trace , when pouring the mold , eventually overthrow the straws because the mass had no fluidity, accumulated in the center , and then gained height spread and dragging the straws . Not to miss the mass of soap removed the straws and put the two parts ( going to use two molds ) in a mold only . I noticed that there was formation of a gel intense and demolded after 24 hours , it was already possible to notice this drawing at the top of the block and cut when I saw that the entire block with this design was different and beautiful, reminiscent of the travertine marmore.

Notice then that is not a decoration , something that was planned to give this effect , it is a defect , handsome, but a defect . Let then the explanation of what happened , within a reasonable understanding of the phenomenon . The trace was accelerated I used a mixture of essential oils – lemon , eucalyptus stageriane and citronella, 3 % ( w / o) in equal parts and one of them , the lemon potentiated the trace acceleration . When I added the mass and felt there was an interaction immediately stopped homogenize , divide the dough into two parts and poured in the mold the volume small, but it was too late the viscosity was inappropriate to make polka dots , that just dropping the straws .

How to put it all together in a mold just to keep the soap , the mass ( 4.3 kg ) occupied almost entirely the mold . This mold (18 x 30 x 8 cm ) and the volume occupied by the mass ratio is conducive to the development of the gel phase with great intensity. The mold with 20 mm MDF with lid , is a great insulator , little heat is lost .

Most times I get partial gel in this mold , but this time the gel was full due to the higher volume of mass. You notice the difference partial gel by  color, darker in the center and lighter edges . Sometimes it is difficult to observe the full gel, there are no such differences can be noted. But whatever the gel anything resembling the soap obtained from this drawing , but the gel is important to have this effect , this defect .

Let us understand what is the gel. When conditions of emulsification (trace) is complete , the saponification reaction begins to be continuous , and generates heat as the saponification chemical reaction is exothermic. This heat is dissipated at the edges and in top of mass of the soap, but it is in center core is where the conditions are perfect for accumulating heat – dissipates less heat , and at this point the temperature increase is substantial. The liquid crystalline molecules acquire mobility and there is the formation of a temperature gradient from the middle to the ends through which you can see the color change and, in some cases, the location is bright and also the viscosity of which decreases . Often this gradient formed will lose the heat of reaction and also decreases by not supplying sufficient heat to keep more the gradient gel and thus ceases to form a partial gel . When the reaction is longer (higher soap mass) , and heat loss is inhibited , the gel is spread and has the full gel.

When I felt a mixture of essential oils was accelerating the trace , stopped and homogenize this mixing time was not enough to mix well to incorporate the oil in the emulsion . When the gel formation , the spread of the temperature gradient ahead is not homogeneous but one local mass with different concentrations of soap and essential oil mixture  . This discontinuity of the medium caused the gel to leave trail in the form of drawings which gave a similar effect designed décor . Dare to say that this gradient gel there was even a mass transport a physical displacement of mass, mass essential oils emphasized that the drawings . The color was also changed, a beige color and has the same amount of titanium dioxide domino soap , which was quite white.

Already tested this soap prematurely and noticed nothing unusual that makes me assume that the performance has not changed or been compromised . The soap has a basic formulation of palm oil / babassu / olive oil / castor – 35/30/30/5 , SF 5% lye concentration of 30% and titanium dioxide ( 1% o / o).

There is a beautiful effect caused by a beautiful defect ! An effect that perhaps can never be reproduced exactly , was a single moment of the mysteries of chemistry of the soap.
