As a vitamin supplement, the product contains water-alcohol or water-alcohol-glycerol extracts of plant materials, while the aqueous medium contains a decoction of herbs obtained by maceration of crushed plant materials in a fluidized bed under vacuum in an aqueous medium, followed by preservation with an alcohol-containing composition (patent No. RU 2283082 )

The disadvantages of the known hair care products are the introduction of an alcohol-containing extract into the shampoo, which can cause negative consequences - dryness and irritation of the scalp, as well as a low content of biologically active components in the decoction (0.01-1.0%).

Closest to the claimed tool is a means for the care of the scalp and hair in the form of shampoo (patent RU No. 2486889) containing surfactants, foam stabilizer, a grease additive, a preservative, a pH stabilizer, a target additive to improve the structure of hair, as The vitamin supplement contains freshly squeezed alfalfa juice, conditioner, water softener, fragrance and water.

The disadvantage of the above funds is that it has a short shelf life.

The objective of the invention is to increase the shelf life of shampoo for dry and severely damaged hair.

The technical result is to increase the shelf life of shampoo for dry and severely damaged hair due to exposure to microflora of the cell juice of alfalfa, ultraviolet rays.

The technical result is achieved in that the shampoo for dry and severely damaged hair containing surfactants, a foam stabilizer, a grease additive, a preservative, a pH stabilizer, a target additive to improve the hair structure, a vitamin supplement, conditioner, water softener, perfume and water, this additionally contains laurel essential oil, and freshly squeezed alfalfa juice introduced as a biologically active vitamin supplement is subjected to UV treatment with a wavelength of 210-240 nm, in a layer thickness of 30-50 mm, for 10-30 mi .

An advantage of the developed shampoo for dry and severely damaged hair is the introduction of freshly squeezed alfalfa juice into the formulation, subjected to UV treatment with a wavelength of 210-240 nm, in a layer thickness of 30-50 mm, for 10-30 minutes. UV treatment actively inhibits the growth of microflora of freshly squeezed alfalfa juice, which allows to increase the shelf life of shampoo.

Alfalfa cytoplasmic juice is a source of biologically active substances that have a beneficial effect on human skin and hair. Alfalfa juice contains vitamins, amino acids, carbohydrates, chlorophyll, high molecular weight alcohols, flavonoids, alkaloids, saponins, coumarin derivatives, pantothenic and folic acids, various minerals, including calcium, iron and phosphorus. The vitamins C, K, group B, which are part of the composition, are the catalysts of the most important biochemical reactions both in the body as a whole and in the layers of the skin and hair. They are responsible for the healthy condition of the skin and hair, and also fight against premature cell aging and collagen degradation, increase wound healing and help strengthen hair. Amino acid molecules provide balanced physiological nutrition and hydration of skin cells. The abundance of trace elements and mineral salts also provides active skin hydration. Low molecular weight organic acids, such as pantothenic and folic, give shine and smoothness to hair, reduce hair oily.

Physico-chemical characteristics of shampoo components for dry and severely damaged hair.

As a surface-active substance (surfactant), the product for the care of the scalp and hair in the form of a shampoo contains a mixture of anionic and nonionic surfactants, in particular sodium ethoxylated lauryl sulfate or sodium sulfoethoxylates in an amount of 5.5-10.0 wt. % and alkylamidopropylbetaines in an amount of 0.5-5.0 wt. %

Diethanolamides of synthetic fatty acids, in particular diethanolamides of fatty acids of coconut oil, are used as a foam stabilizer and, at the same time, a structural agent in the composition for head and hair care in the form of shampoo. These are nonionic surfactants, a thickener for detergents based on AAS. These surfactants have a softening effect on the skin, stabilize the foam, and thicken aqueous solutions of anionic surfactants.

As a target additive for improving the structure of the hair, the product for the care of the scalp and hair in the form of shampoo contains PEG-7 glyceryl cocoate. The target additive creates an optimal balance of fat content, which allows the use of the claimed product for normal and dry hair, strengthens the hair roots, gives them a natural shine and beauty, provides a conditioning and anti-static effect with a simultaneous tonic and restorative effect.

As a conditioner, the product for the care of the scalp and hair in the form of a shampoo contains polyquaternium - 10 - cationic cellulose derivative. Substrate to skin and hair, thickener. Improves styling, shine of hair, reduces their electrification. It contains sodium chloride as a grease additive (table salt "Extra").

A weak organic or mineral acid, for example citric acid, can be used as a pH stabilizer.

As a preservative in the composition for treating scalp and hair in the form of a shampoo, methyl paraben and propyl paraben, which is a white crystalline powder, are used. It is well soluble in water, ethanol. It has a fungicidal spectrum of action, and is also active against gram-positive bacteria.

In order to create a pleasant specific smell, a fragrance additive (perfume) was added to the composition of the product for the care of the scalp and hair in the form of shampoo (perfume composition to mask the smell of the base and give a pleasant aroma of the product).

As a water softener in the composition for the care of scalp and hair in the form of shampoo, disodium ethylenediamine salt - trilon B (GOST 291882-91) is used. Trilon B is a chelating agent. It is used to bind polyvalent metal cations, as a stabilizer, detergent activator, and scale inhibitor. In addition, it exhibits the properties of synergists, antioxidants, preservatives, which is explained by the ability to complexation.

Laurel essential oil in its composition contains the main components of 1,8-cineole, terpenyl formate, as well as linalool, α- and β-pinels, sabinene, α- and β-fellandrenes, limonene, camphene and sesquiterpenic compounds. The introduction of laurel essential oil suppresses the vital activity of microorganisms, accelerates the healing process, soothes itching and burning.

To prepare shampoo for dry and severely damaged hair, it is necessary to load a prescription amount of the cytoplasmic fraction of alfalfa juice obtained by pressing and subjected to UV treatment with rays of a wavelength of 210-240 nm, in a layer thickness of 30-50 mm, for 10- 30 minutes. Then, with stirring, the solution is heated to a temperature of 50 ° C, surfactants are loaded from the container of the supplier. Concentrated sodium laureth sulfate and PEG-7 glyceryl cocoate are fed to the main apparatus using a submersible pump. Gravity feed from the measurer into the apparatus serves diethanolamides of fatty acids of coconut oil, polyquaternium-10. Mixing of the components is carried out with the included scraper mixer. Next, carry out the cooling stage. When the solution cools to a temperature of 30-35 ° C, Trilon B, citric acid in the prescribed amount of water, is fed into the apparatus. The last injected preservative, laurel essential oil and perfume. Sodium chloride is added to thicken the solution. After stirring, the mass of shampoo is filtered. The finished mass of shampoo is served at the stage of maturation (2-3 hours) and then for bottling and packaging.

To confirm the claimed technical solutions, the following experiments were carried out - the products were made according to the claimed recipe and according to the recipe of the prototype according to the classical technology without UV processing of alfalfa juice. The experimental conditions are shown in table 1.

In determining the boundary conditions of the experiment, a range of UV radiation from min = 210 to max = 240 nm was adopted; the layer thickness of the processed juice was determined by the possibility of transillumination of the juice, and was adopted from 30 to 50 mm; the duration of UV-radiation treatment is accepted in the range from the initial microflora suppression effect to providing complete suppression and is accepted from 10 to 30 minutes.

Processing of alfalfa juice was carried out in a quartz tube of different thickness and length, providing experimental conditions.

To prove the effect of UV radiation on the suppression of microflora in alfalfa juice and to increase the shelf life of the finished product made on the basis of processed juice, we performed a series of experiments using the mathematical modeling method. The matrix of the experiment is shown in table 2. The response function adopted the dependence of the change in the storage time of the finished product in days until the signs of fermentation appear in the product. Storage conditions for accelerated aging - storage in a thermal moisture chamber at a temperature of + 42 ° C and a humidity of 65%.

Processing the results of the experiment made it possible to obtain optimal conditions for storing the finished product for one year:

- UV irradiation intensity - 220 nm;

- juice layer thickness - 30 mm;

- UV exposure time - 30 minutes

The experiment, conducted according to the recipe of the prototype without UV treatment and subjected to accelerated aging, showed a maximum shelf life of 31 days.

The antimicrobial efficacy of juice treatment with UV radiation was tested before it was introduced into the shampoo by diffusion into agar using wells. The results of the studies are shown in table 3.

Analyzing the data of the table for determining the sensitivity of microflora, we establish that treatment with UV radiation actively inhibits the growth of microflora.

As can be seen from the above examples, the task and the claimed technical result are achieved.
