Description

The invention relates to the field of pharmaceutical chemistry, in particular to the field of cosmetology, and relates to hygiene products for women, designed to cleanse and wash the skin and mucous membranes of the intimate area.

In the field of modern cosmetology, there is a wide range of personal care detergents. However, numerous traditional cleansers containing alkaline soaps are unsuitable for regular care of sensitive intimate parts of the body, as they upset the pH balance of the natural environment in the intimate area and can create favorable conditions for the development of infection and the propagation of fungi. To maintain physiological pH values and enhance washing properties, milk serum, lactic acid and protein hydrolyzate are often introduced into modern personal care detergents. The use of whey and protein hydrolyzate is due to the fact that they are natural products containing animal proteins, amino acids, trace elements, vitamins, a complex of minerals, which determines the high washing properties of the whole composition, in addition, these components have a beneficial effect on the skin and hair integument without causing irritation. Whey is a regulator of the concentration of hydrogen ions (pH) and a regulator of viscosity. Lactic acid is an effective natural preservative with antibacterial effects. Lactic acid is a natural metabolite of the cells of the human body, therefore, it has long been used as a natural prophylactic and care products in the intimate area.

Known hygiene product, made in the form of a cream and containing disodium salts of sulfonate succinic acid monoesters, protein hydrolyzate, fatty acid alkylamides, preservative, pH regulator, dye, perfume perfume and water at a certain ratio of components (A.S. USSR 1796181, 1988).

Known foaming personal care products containing sulfoethoxylates, monoethanolamides of synthetic fatty acids, dicarboxybetaine or cyclimide, glycerin, formalin, deproteinized whey concentrate, perfume, dye and water in a certain ratio of components (AS USSR 1606122, 1988).

Known personal care detergent containing sulfoethoxylates, diethanolamides of fatty acids, betaines, sodium chloride, glycerin or protein hydrolyzate or propylene glycol, the liquid phase of peat or diluted peat water extract, nettle extract, additives and water in a certain ratio of components (patent RU 2174831, 2000 ), the tool provides stimulation of the skin and hair and normalization of the water-salt balance of the skin and hair.

Known personal care detergent containing diethanolamides of fatty acids, concentrate deproteinized whey, sulfoethoxylates, glycerin, formalin, ethyl alcohol, perfume, dye and water with a certain content of ingredients (AS USSR 1342503, 1985).

There is a detergent for women’s intimate hygiene that contains lactic acid, atomized milk whey, low viscosity texapon surfactant, flavoring agent, cholesterol, ethyl hydroxyethyl cellulose, milk wax, M-sodium nipagin, phosphoric acid, sodium hydroxide and water in a certain ratio components, pH = 3.5 (production: Israel). However, a low pH = 3.5 can lead to irritation in the intimate area, as well as disrupt the natural microflora. Glaxo Smith Kline produces the daily Lactacyd Femina intimate care washing emulsion, which contains magnesium laureth sulfate, disodium laureth sulfosuccinate, cocamidopropyl betaine, glyceryl laurate, glycol disterate, sodium laureth sulfate, lactose, milk protein, milk-pegyl, 57 , 5-bromo-5-nitro-1,3-dioxane, perfume and water, the product has a pH = 5.2, it is used as a liquid soap. The specified tool, made in the form of an emulsion, is not economical enough.

The objective of the present invention is to provide a domestic detergent for intimate hygiene of women with high washing properties and devoid of these disadvantages. The problem is solved by the fact that the proposed hygienic intimate detergent in the form of a gel for women, containing biologically active ingredients, surfactants, preservative, opacifier, perfume and water. As biologically active substances, lactic acid and sour milk whey are used. Due to its inherent properties, lactic acid maintains a pH close to natural, maintains its own protective functions of the skin and mucous membrane, at the same time cleanses and cares for intimate parts of the body gently and gently. Acid whey plays two roles in the composition, being both a humidifier and a regulator of the concentration of hydrogen ions (pH), and together with lactic acid it creates a buffer system, stably maintaining the gel pH at pH = 4.0-5.0. Glycerin is also used as a humidifier, and hydroxyethyl cellulose, a cellulose derivative, is used as a gelling agent. Preservation is provided by germaben 2-E (Germaben 2-E), which is a viscous liquid. Clouding is a ready-made, commercial Lamesoft product ”, which is a mixture of glycol distearate, cocoglycoside, glyceryl oleate and glyceryl stearate. Surfactants are disodium sulfosuccinate and cocoglycoside. To give a pleasant smell, a fragrance is introduced into the composition - ginseng and green tea. The gel composition also contains purified water.

The proposed gel has the following composition, in mass. %:

Disodium sulfosuccinate 12.0-16.0

Cocoglycoside 1.0-3.0

Glycerin 1.0-6.0

Hydroxyethyl cellulose 0.5-2.5

Lamesoft 1.0-3.0

Whey 0.1-1.0

Lactic acid 0.1-0.5

Hermaben 2-E 0.5-1.0

Fragrance 0.2-0.4

Water rest

The claimed detergent for intimate hygiene of women is obtained as follows. The technology of obtaining the claimed agent is reduced to mechanical mixing in a certain sequence of prescription amounts of its constituent components: whey powder is added to warm water with constant stirring, then hydroxyethyl cellulose, sulfosuccinate and cocoglycoside are added until a uniform thick gel is formed, then glycerin, a turbidizer, a preservative are added, lactic acid and perfume.

The finished product is a homogeneous white gel-like mass having a pH of 4.0-5.0. The technical result obtained by using the invention is expressed in expanding the range of detergents for intimate hygiene of women, creating a physiological gel, applied without loss and providing a natural balance in the intimate area.

The invention is illustrated by the following examples.

Example 1. The claimed tool has the following composition, mass. %:

Disodium sulfosuccinate - 12.0

Cocoglycoside 3.0

Glycerin - 1.5

Hydroxyethyl cellulose - 0.8

Lamesoft - 1.0

Whey - 0.1

Lactic acid - 0.5

The claimed tool was tested in an experiment and on a group of volunteers.

In the experiment, toxicity in mice was studied. The animals of the experimental and control groups were cut hair on the back and the claimed agent was applied to the skin of mice of the experimental group, the exposure time was 2 hours, after that the agent was washed off with warm water and the skin condition of the animals was visually determined. No differences between the experimental and control groups were found. Based on the experiment, we can conclude that there is no toxicity in the claimed funds.

The volunteer group consisted of 7 women who, prior to testing the claimed product, used imported detergents for intimate hygiene, while 3 out of 7 women noted discomfort and mild irritation in the intimate area with daily use of these products. The claimed tool was used for 30 days. After this period, a survey was conducted of all patients in the group, which revealed the absence of discomfort and irritation in the intimate area. Volunteers noted the high cleaning properties of the claimed funds.

Thus, the claimed tool does not show toxicity, has high detergent properties, physiologically, which will allow it to take its rightful place among detergents for intimate hygiene of women.
