Description

FIELD OF TECHNOLOGY

The invention relates to the cosmetic industry and can be used for gentle hair coloring.

PRIOR ART

Human hair is in many respects identical to animal hair - the main "building material" in both cases is the keratin protein. Keratin consists of 19 amino acids and makes up 90% of the hair mass. Each hair consists of 3 layers: the outer layer or cuticle is an oblong keratin scales that overlap each other, like chain mail scales, and act as an outer protective layer. Under the cuticle is the second layer - the cortex, which consists of elongated cells that give the hair strength and elasticity. The center of the hair consists of the medulla, which includes soft keratin cells and air cavities. The hair follicle is located under the skin and is called a follicle. The type of hair depends on the shape of the follicle: straight hair grows from round follicles, wavy hair grows from oval follicles, curly hair grows from kidney-shaped follicles. The follicle shape gives the structure to the amino acid chains: when the amino acid chains are not linked by additional bonds, the hair acquires a straight shape, if more bonds are formed between the acids, the hair acquires a wavy shape. From the point of view of biochemistry, the role of such additional bonds is played by disulfide and hydrogen bonds, as well as the ionic interaction of functional groups of the side chains of keratin.

Changing natural hair color has been practiced since ancient times, and natural dyes have been used for this purpose for centuries. Only from the end of the 19th century, as the chemistry of synthetic dyes developed, they began to be used not only for dyeing fabrics, but also for dyeing hair. The prerequisite for this was the unconditional similarity of human hair with animal hair. Therefore, for hair dyeing, such technical classes of dyes as acidic, basic (cationic), active, dispersed and others, which are used to color wool, began to be used. Subsequently, these dyes were called direct dyes. However, as it turned out, the colors obtained with these dyes are very unstable and can only be used to temporarily add color to the hair. This is quite understandable, since large-sized dye molecules cannot penetrate into the hair, but are fixed only on the surface due to van der Waals forces, London forces, and hydrogen bonds.

Compositions for dyeing hair, which are solutions of dyes in water [US 7198651 B2 publ. 04/03/2007 FUJI PHOTO FILM CO., LTD; US 7241318 B2 publ. 07/10/2007 CREATE CO.], Have certain inconveniences when applied to the hair: the scalp is intensely colored and the paint flows onto the front of the head, while the color on the hair is not saturated enough. To overcome such difficulties in application, it is proposed to somewhat thicken the compositions for dyeing hair, making gels that are better adhered to the hair, but do not prevent the transition of dyes to hair keratin [US 6740129 B2 publ. May 25, 2004 HENKEL LION COSMETICS CO. LTD]. Creamy compositions have been developed that are even more comfortable to use, but more strongly prevent the transfer of dyes to the hair, which required an increase in dyeing time. A creamy consistency is obtained by introducing various fillers: granular cellulose [US 7204856 B2 publ. 04.17.2007 HENKEL KGAA]; thickening polymers of anionic, cationic and nonionic type [US 7300470B2 publ. 11/27/2007 L'OREAL S.A.]. Thickening emulsions are widely used, for example, compositions containing high molecular weight alcohols C12-C20, glycerol monostearate, potassium salts of fatty acids [US 7204859 B2 publ. 05/25/2010 L'OREAL S.A]. But creamy emulsions have another drawback - due to their high density, it is not always possible to achieve uniform distribution and coloring of hair in the total mass. Therefore, dyeing foam compositions for hair are produced, which are easy and convenient to apply, they soak the hair well, resulting in uniform coloring.

The first dyeing foam compositions for hair were developed on the basis of direct-acting dyes placed in conventional tubes [WO 2009077302 A2 publ. 06/25/2009 HENKEL AG & CO KGAA], and then for two-phase systems [DE 102006055436 A1 publ. 11.10.2007 HENKEL KGAA]. To ensure foaming of the coloring composition, cationic polymeric materials were introduced into them.

As dyes for deep and long-lasting (persistent) hair coloring in most cases, it is proposed to use oxidation dyes [FR 2870733 B1 publ. 07.07.2006 L'OREAL SOCIETE ANONYME; US 7044986 B2 publ. May 16, 2006 KAO CORPORATION; US 7056497 B2 publ. 06.06.2006 PROCTER & GAMBLE]. This is determined by the following requirements for hair dyes: 1) dyeing should take place for a short period of time at room temperature and should not cause damage to the hair shaft or scalp; 2) dyes should give hair a natural color and paint over the scalp to a minimum; 3) a short dyeing time requires the use of formulations with a high concentration of dye; 4) the diffusion of the dye into human hair is much slower than into the keratin of the wool, therefore, dyes of small sizes with a low molecular weight are required. Only oxidation dyes meet these requirements.

Direct-acting dyes - nitro-, acidic, basic (cationic), active, dispersed - are added to the coloring compositions to give the required shade, and they are retained mainly on the hair surface due to the formation of hydrogen bonds, van der Waals forces and London, not penetrating deep inside due to the large size of the molecules and the low diffusion rate, as a result of which they are quickly washed off.

A revolution in the field of hair dyeing was the proposal to use not ready-made dyes themselves, but intermediate products for their production: aromatic diamines and aminophenols. The molecules of these compounds are small, easily penetrate into the hair and there, under the action of an oxidizing agent, are converted into colored indamines, indanilines and indophenols, which are then di- and trimerized, forming heterocyclic pigments with a high molecular weight, unable to leave the hair, which ensures high color fastness. These intermediates are called oxidation dyes. By analogy with the photographic process, these compounds are also called developers. These include aromatic o- and p-diamines of the benzene and naphthalene series, o- and p-aminophenols and their derivatives, analogous derivatives of the series of pyridine, pyrimidine and other heterocycles.

When these compounds are oxidized, for example, with hydrogen peroxide, persulfates, perborates, dichromate and potassium or sodium chlorate, they are converted, as already mentioned, into quinone imines, then into indamines or indanilines. Further oxidation leads to the formation of phenazine structures containing several hetero rings. Since a mixture of many products is formed as a result of these reactions, the hair is dyed in dull, blurry tones that completely imitate natural colors: light brown, brown-haired, chestnut.

Developers, or colored bases, are usually used in a mixture with so-called colored components. These are m-diamines, m-aminophenols, phenols, naphthols, pyrazolones, β-diketones and their derivatives. These compounds by themselves do not give color, but reacting with the developer, they expand the color gamut of coloring compositions, for example, p-phenylenediamine with m-toluylene diamine forms a red phenazine dye, and with 2,4-diaminoanisole, a violet-blue indamine:

For effective penetration of both oxidizing dyes and oxidants into the hair, the dyeing process is carried out, as a rule, in an alkaline medium, which destroys the outer protective layer of the hair and loosens the inner layers of the hair. Of course, this causes irreparable damage to the hair: they lose shine, strength, become brittle, brittle, thinner; their tensile strength is significantly reduced. This becomes especially noticeable with constant staining.

Effective penetration of dyes into the hair becomes possible when the outer layer of the hair is sufficiently loosened. Cuticle scales rise when the hair is exposed to alkalizing components. Usually, in the cosmetics industry, ammonia and / or aliphatic amines and / or amino alcohols are used to solve this problem. These components have an unpleasant odor, and as a result, their use entails the need to use perfume compositions.

The use of perfume additives is widespread in the cosmetic industry and has been mentioned since ancient times. So, in the ancient Egyptian chronicles, perfumery is mentioned, they were found by archaeologists in tombs and palaces during excavations. The foundations of perfume technology were laid in Greece and subsequently developed in the Middle East. They used methods for extracting aromas that are often used in our time: steam distillation and direct extraction. Scented extracts were added to ritual cleansing products for hair and body, medicinal ointments and rubbing, and were used simply for pleasure.

In the Middle Ages, the technology of the perfumery and cosmetic industries received a significant impetus with the development of science, including alchemy. Also, the active development of new areas of the planet entailed the discovery of new sources of raw materials for the creation of perfume.

During the Renaissance, the creation of perfume compositions reached a new level and their use became the absolute norm of life. They smelled not only clothes and body, but also unpleasant smelling cosmetics and medicines. Even then, it was noticed that the addition of some fragrances significantly changes the properties of the product to which they are added.

Currently, there are several different types of perfume compositions, differing in the method of application. They differ by the type of solvent, by the type of application, etc. At the same time, when creating a perfume composition, the scope of its application is taken into account. So, when creating a perfume composition for permanent hair dye containing ammonia and / or other components with a pungent and unpleasant odor, the following parameters are taken into account:

1. The composition should completely or partially cover the unpleasant odor, improving, but not worsening.

2. The composition should not destroy the paint base - change the rheology of the gel, destabilize the cream emulsion, etc.

3. The composition should not affect the paint during the entire shelf life.

The first point is almost always possible to take into account at the stage of creating a perfume composition, but the second and third points can only be taken into account when creating a finished product - hair dye.

Accelerated aging method is used for preliminary assessment of possible negative effects on paint during storage. It consists in keeping the finished composition in commercial packaging for a certain time at an elevated temperature in the absence of mixing the composition, vibrations, etc. However, in real storage conditions, stability can be influenced by those factors that are artificially excluded in the test, as well as imperfections in the method that do not take into account many features of modern cosmetic raw materials.

The main factors in the rejection of a perfume composition are destabilization of the base and a change in color during storage. These effects are due to the fact that the composition of the perfume can include dozens of components, many of which are capable of reacting at one rate or another with both base components and dye molecules.

The technical result of this development was the ability to exclude the negative effect of the components of the perfume composition on hair dyes during long-term storage, as well as the possibility of using any type of perfume composition for scenting hair dye, taking into account the fact that the composition closes the base odor without worsening it.

Surprisingly, it has been found that the addition of a perfume composition based on ethanol or even on any other basis to the dye mixture for hair after direct mixing, i.e. after mixing the paint with an oxygenating agent, it does not affect the color characteristics during the coloring process. In addition, the time traditionally allotted for the coloring procedure is not enough for the reactions of the components of the perfume composition with the paint base to pass. It was also found that in order to solve the problems of maintaining the physical and mechanical characteristics of hair during dyeing, it is necessary to use certain components in certain concentrations. Such components are useful and optimal in the disclosed improved coloration technique, but have an unpleasant odor that must be hidden by the perfume composition. Surprisingly, it has been found that when the perfume composition is added to the dye mixture immediately before application to the hair or directly to the hair, the physical and mechanical characteristics of the hair are significantly increased than in the case of adding the perfume composition to the paint in advance. These and additional technical results are described in more detail and confirmed below.

With the introduction of ethanol-containing perfume compositions into the base paint or oxygen, it was found that the stability of the emulsions decreases until complete disintegration. The use of a perfume composition with an ethanol content of more than 90% loses its meaning, because the possible amount of perfume composition will no longer mask even the smell of ethanol, not to mention the components of paints that have an unpleasant odor.

An amount effective to reduce the intensity of an unpleasant odor to an acceptable level has been determined during the colorant formulation. GOST 29188.0-2014 describes a method for organoleptic assessment of the odor of a perfumery and cosmetic product. When creating a formulation, the developer adds perfume compositions to the composition starting from small amounts, gradually increasing the percentage of input until the aroma of the perfume composition overlaps the smell of the base, including ammonia, amino alcohols and other components with an unpleasant odor. At the same time, it is impossible to use high concentrations of perfume compositions, because the allergens included in their composition cannot be contained in the product in quantities exceeding the permissible ones.

The auxiliary components can be ingredients conventionally used in the art having various cosmetically acceptable properties. Such components can be, for example, hydroxyethyl cellulose, sodium sulfite, sodium isoascorbate, disodium EDTA, and others.

Where Control ₁ and Control ₂ are the original hair before dyeing, taken from two different batches.

It was found that the hair after treatment with Formulation 4 exhibits excellent physical and mechanical characteristics, however, Formulation 4 has a pronounced unpleasant odor, which prevents its use.

Research No. 2. Elimination of unpleasant odor.

To eliminate the unpleasant odor of the components, perfume compositions 1, 2, 3, 4, 5 and 6 were introduced in equal amounts. The smell of finished paints was investigated according to GOST 29188.0-2014. The result was assessed on a five-point scale, where 1 is the least unpleasant, 5 is the most unpleasant. The assessment was carried out in accordance with GOST 29188.0-2014 Perfume compositions 1, 2 and 3 did not contain ethanol, perfume compositions 4, 5 and 6 contained ethanol. The results are presented in Table 3.

Table 3.

Perfume compositions, no. one 2 3 4 five 6 Smell, score five 4 4 2 2 one

Thus, it was found that with equal percentages of the addition, perfume compositions containing ethanol more effectively cover the unpleasant odor of the base components. At the same time, it was found that with the introduction of ethanol-based perfume compositions into the paint base, the colloidal stability of the product during storage drops significantly and the paint ceases to meet the requirements for perfumery and cosmetic products.

To solve this problem, a solution was found to add an ethanol-based perfume composition to the dye mixture immediately after its preparation.

Study No. 3. Solving the problem with stability (option 1).

The dye was mixed with an oxygenating agent, held for up to 3 minutes to initiate the oxidation reaction, an ethanol-based perfume composition was added to the mixture and applied to the hair. Further dyeing was carried out according to the usual technology inherent in most hair dyes.

The exposure time from 30 seconds to 3 minutes was set so that the oxidation reaction in the coloring mass began without affecting its kinetics of the components of the perfume composition. At the same time, it is impractical to withstand the paint for more than 3 minutes, because the dyeing time is reduced, and, accordingly, the dyeing efficiency may decrease. Surprisingly, it was found that the standard dyeing time from 20 to 60 minutes is not enough for the negative influence of the components of the perfume composition on the color characteristics of the paint, as well as on the colloidal stability of the mixture on the hair. The colors on the volunteers corresponded to the declared color, the paint did not exfoliate on the hair, did not leak. Surprisingly, it was found that the mechanical properties of colored hair were significantly better when the ethanol-based perfume composition was added to the coloring mixture after preparation (mixing), compared to a hair dye that already contains an ethanol-based perfume. The results of physical and mechanical tests are presented in Table 4.

Research No. 5. The durability of the paint

When ethanol is added to the dye mixture, the color stability is significantly increased; however, when perfumes are introduced, the stability of dyes and colloidal stability during storage decrease.

It was found that the introduction of ethanol significantly increases the color fastness. This is due to the improved defatting of the hair with ethyl alcohol and the greater availability of hair for dyes. The dye composition penetrates the hair better, more dye remains in the hair after the dye composition is washed off. At the same time, the fatty base of the paint softens and effectively moisturizes the hair, preventing overdrying and increasing their fragility.

Studies were carried out in accordance with GOST 9733.4-83, which describes a method for testing textile materials for color fastness. It consists in multiple treatment of tissue samples with stearate soap and subsequent assessment of the stain. The present inventors adapted it by treating colored hair with a test (standard) shampoo and evaluating the color change in Lab coordinates.

Test method: Colored hair was immersed in a 25% aqueous solution of test shampoo and mixed for 15 minutes. The hair was removed, dried with hot air, and the color was assessed in Lab coordinates. Washing was carried out until the results were as close as possible to the initial coordinates of at least one sample. The data are presented in Table 6.

Notes: perfume 1 does not contain ethanol, perfume 4 and 5 contain 76% ethanol, perfume 6 contains 72% ethanol. The sample "Without perfume" was tested to exclude the influence of the perfume composition on the durability.

Thus, it can be seen that in the case of using perfumes containing ethanol, the color stability is significantly increased. If in the case of samples without perfume and without alcohol perfume, the hair color was almost 100% equal to the initial one for the fourth wash cycle, then in the case of using perfumes 4, 5 and 6, the color was washed off by approximately 68-72%.

Study No. 6. Reaction of perfume with dyes

Samples of hair dyes with different perfumes and a sample without perfume were artificially aged in an oven under controlled conditions (42 ° C, no vibration and no stirring). Every seven days, a sample was taken from each sample and a test solution was prepared. The test solution was distilled with steam. About 5 g (accurately weighed) of distillate was placed in a 100 ml volumetric flask and analyzed according to the method for the quantitative determination of dyes in the aqueous phases of paints.

Fragrances 1, 2 and 3 do not contain ethanol. Fragrances 4 and 5 contain 76% ethanol. Fragrance 6 contains 72% ethanol.

The content of dyes X in weight percent was calculated by the formula:

Where:

S is the area of the dye peak in the chromatogram of the test solution;

S₀- dye peak area on the chromatogram of the standard solution;

a ₀ - weighed amount of dye when preparing a standard solution in grams;

A - paint sample during preparation of the test solution in grams;

k is a numerical factor that takes into account the volumes and dilution of solutions.

It was found that during artificial aging, all samples underwent a quantitative change in composition, regardless of the perfume that was introduced into them. In this case, the compositions with perfumes No. 5 and No. 6 underwent the most dramatic changes. After 21 days, the PAOC and 24 DAPE peaks were almost invisible on the chromatograms. In formulations No. 2 and No. 3, the content of the EG dye dropped sharply. Compositions with perfumes No. 1 and No. 4 remained practically unchanged, the content of dyes remained comparable to the control sample. The Tables show the amounts of dyes (X) in samples for 0, 1, 2, and 3 weeks, respectively.

At the same time, the sample without perfume practically did not undergo any changes, which confirms the effectiveness of excluding the perfume composition from the paint composition.

Study No. 7. Stability of the emulsion

GOST 29188.3-91 describes a method for determining the stability of emulsions. It consists of thermostating the samples at 42 ° C for 24 hours, followed by testing the sample in a centrifuge at 6000 rpm for 5 minutes and then assessing the amount of exfoliated liquid. Samples were tested containing perfumes 1, 2, 3, 4, 5, 6 and a sample without perfume. The samples were also tested by the same method after 21 days of artificial aging under controlled conditions. According to the test conditions, if more than 0.5 ml of liquid peels off, the emulsion is considered unstable. The data are presented in Table 11.

Table 11.

Sample number Without perfume one 2 3 4 five 6 The volume of the exfoliated liquid, ml 0 0 0.06 0.01 0.70 0.72 0.61 The volume of exfoliated liquid 2, ml 0.10 0.32 0.38 0.28 2.41 2.55 2.47

Thus, it can be concluded that ethanol-containing fragrances have a negative effect on the stability of emulsions.
