A disadvantage of the known shampoos is that they cannot provide a sufficiently high level of therapeutic properties.

As a prototype adopted shampoo containing a natural mineral, which is used as an aqueous extract of blue Cambrian clay as a solvent and a source of micro and macro elements. Patent of the Russian Federation No. 2195923, IPC: А61К 7/08, 2003.

The shampoo has the following composition, wt.%: Clay extract (blue Cambrian clay) 5.0-15.0; surfactant (one or more) 7.5-25.0; thickener 1.0-5.0; peralescent agent 1.0-3.0; food coloring 0,0-0,0005; extracts of medicinal plants 1.0-6.0; preservative 0.05-0.5; perfume 0.1-0.3; pH stabilizer 0.05-0.2; water is the rest. As surfactants, in particular, sodium sulfoethoxylate is used as an anionic surfactant, coconut oil fatty acid diethanolamide as a nonionic surfactant, alkylamidopropyl betaine as an amphoteric surfactant. Sodium chloride is used as a thickener, and citric acid is used as a pH stabilizer. Extracts of medicinal plants are introduced into the shampoo as a natural vitamin supplement: extracts of birch leaves, burdock root, chamomile flowers, calendula flowers, nettle, oak root. In addition, perlescent agent, dye, preservative and perfume are introduced into the shampoo. The specified shampoo due to the presence of a source of micro - and macrocells has a high level of therapeutic and prophylactic effect. However, this level can be expanded by using other medicinal minerals in shampoos.

In most cases, cosmetics manufacturers use Carbomer as a thickener. Carbomer is a high molecular weight carboxyvinyl polymer that is sensitive to the pH value in the formulation, which leads to incompatibility with cationic substances.

The objective of the invention is the expansion of the range of manufactured shampoos with a high level of therapeutic and prophylactic action.

The technical and cosmetic result of the invention is to improve the structure and consistency of the cosmetic product, improve tactile sensations, even distribution of the active substances contained in the product on the hair and scalp, stabilization of the formulation, and compatibility with surfactants and electrolytes.

The technical result is achieved in that in a shampoo for washing hair containing a surfactant, preservatives, perfume, pH stabilizer, viscosity regulator, natural vitamin supplement, water and a natural mineral, laureth-5 - sodium carboxylate is used as a surfactant , bentonite was used as a natural mineral, and a softener was introduced - disodium ethylenediaminetetraacetic acid, in the following ratio of components, wt.%:

Laureth-5 - sodium carboxylate 14.0-15.0 Bentonite 1.5-2.5 Disodium Ethylenediaminetetraacetic acid (EDTA) 0.1-0.3 Lemon acid 0.15-0.25 Preservative 0.02-0.05 Perfume 0.3-1.5 Water up to 100%

Laureth-5 - sodium carboxylate - is introduced into the formulation as a detergent ingredient (detergent), which exhibits an emulsifying effect, removes grease from hair and skin (cleanser), and a foaming agent. Lauret-5 reduces the irritating effect, increases the rate of foam formation, and is a basic (primary and secondary) surfactant.

Bentonite is a natural thickener (montmorillonite) - a natural material. Bentonites - white colloidal clay, consisting mainly of minerals of the montmorillonite group (montmorillonit) with a content of montmorillonite of 65-80%. It consists entirely of natural minerals. Bentonite has a thickening property, non-toxic, stable in a wide range of pH and temperature. The specific properties of bentonite are swelling. Chemical composition: magnesium oxide (MgO) 4-9%, alumina (Al ₂ O ₃ ) 11-12%, iron oxide (Fe ₂ O ₃ ) 5% or more, water 12-24%, potassium oxide (K ₂ O), sodium oxide (Na ₂ O) and calcium oxide (CaO) up to 3.5%.

Disodium ethylenediaminetetraacetic acid (EDTA) - a softener. Calcium and magnesium complexing agent to soften water. Chelating stabilizer. Protects the drug from unwanted changes in color and smell under the influence of the environment. Citric acid is a medium regulator (pH) of shampoo.

The method is as follows.

The calculated quantity of demineralized water preliminarily weighed on the balance is pumped into the reactor from an intermediate tank. Turn on the mixer and heating the reactor. The water is heated and maintained at a temperature of 60 ° C.

The calculated amount of EDTA, citric acid, preservative is successively charged to the reactor using a portable pump, and all are mixed until completely dissolved. (The process does not exceed 10 minutes.)

At a temperature of 60 ° C, bentonite is charged. After loading the concrete, the mixture is mixed with a frame-scraper mixer (300 rpm) until the bentonite completely swells. (The process takes about 1 hour.)

Turn off the heating of the reactor and when the temperature drops to 40 ° C, load the calculated mass of Lauret-5 - sodium carboxylate. Laureth-5 sodium carboxylate, mild surfactant, anionic high-foam surfactant, quickly forms a large amount of foam, stable.

Stirred with a frame-scraper mixer (300 rpm) until the surfactant is completely dissolved within 40-50 minutes.

The finished product is kept in the reactor for 40-45 minutes. After that, two product samples are taken to determine the quality indicators (medium pH, viscosity, appearance, smell): from the upper part of the reactor using a sampler and from the lower part of the reactor through a branch, the volume of each sample is at least 200 ml.

After determining the pH and viscosity, the mixture is adjusted with citric acid and the calculated amount of perfume is added. The mixture was re-mixed with a frame-scraper mixer (300 rpm) for 30 minutes. The finished product is kept in the reactor for 40 minutes. Then distributed into vials.

Natural healing components of the shampoo provide enhanced nutrition of hair roots, stimulate hair growth, and prevent hair loss. Regular use of shampoo strengthens them and improves growth. The bentonite content in the recipe allows you to position the shampoo as a cosmetic product with "natural ingredients" ie "green".
