Description

The invention relates to means for dry skin cleaning from various contaminants without the use of water and can be used in everyday life and in production.

Various hand cleansers are known for use without the use of water. For example, a mixture of polyethylene oxide, isopropanol, ethanol, propylene glycol, triethanolamine, an aqueous latex copolymer of styrene, water and a number of other components is known, with a pH of 5.8-6.5. The reasons that impede the achievement of the required technical result when using a known agent include the fact that the paste is ineffective in cleansing the skin of radioactive contaminants.

The closest analogue of the claimed invention is a paste for dry cleaning of hands from contaminants, including radioactive. It consists of polyvinyl alcohol, glycerin, dicarboxybetaine, sodium chloride, benzoic or salicylic acid, the rest is water. The paste may additionally contain citric acid and aluminum nitrate (see RU 2033148 C1, publ. 1995). This paste allows you to quickly and without additional means to remove household impurities, waste grease oils and greases from the skin.

The technical task of the invention was to improve the means for dry cleaning hands from contaminants, in which due to the empirically selected composition of the ingredients, the cleaning ability of the product from radioactive and general technical contamination is increased while maintaining stable viscosity characteristics throughout the entire storage period.

The problem is solved in that the tool for dry cleaning hands from contaminants contains polyvinyl alcohol, glycerin, citric acid, water-soluble cellulose ethers, natural polysaccharides and water in the following ratio of components, wt.%: Polyvinyl alcohol - 8-13, glycerin - 2-4 , citric acid - 0.06-0.12, water-soluble cellulose ethers - 0.3-0.5, natural polysaccharides - 0.6-1.2, water - the rest.

The technical result obtained from the use of the proposed composition is to increase the degree of removal of contaminants from the skin of the hands, increase the stability of the composition, and therefore the shelf life, improve the condition of the skin of the hands and deactivating properties.

The tool can restore its properties after freezing the composition to 25 ° C.

The proposed qualitative and quantitative composition of the product is necessary and sufficient to achieve the specified result.

As natural polysaccharides, chitosan or virin are used.

The tool may additionally contain amphoteric surfactant, for example, a betaine class tenside, as well as Trilon B (disodium ethylenediaminetetraacetic acid salt) in an amount of 0.1-0.3 wt.%, Potassium alum in an amount of 0.01 -0.07 wt.%, Cosmetic fragrance in an amount of 0.3-0.4 wt.%, Preservative in an amount of 0.03-0.06 wt.%, Food coloring in an amount of 0.0003-0.0004 wt. %

The inclusion in the composition of water-soluble cellulose ethers (KMTs-150, KMTs-170, KMTs-600, Aquosorb) give the composition stability and increase the shelf life of up to 3 years. Water is bound in PVA, due to which the composition does not peel off during storage. Water-soluble cellulose ethers also play the role of a complexing agent from radioactive elements.

Natural polysaccharides: chitosan and valirin (3% solution) give the skin elasticity, prevent dry skin after applying the composition, protect it from harmful UV radiation, have anti-inflammatory, wound healing and anti-allergic effects. Along with citric acid, they are good complexing agents from heavy metals and radioactive elements, and in combination with alum potassium alum, they increase the cleaning ability and the deactivation coefficient of hand cleansing from radioactive elements.

Chitosan - is a polysaccharide derived from crab shells. It is used in cosmetics as a moisturizer, film-forming and anti-inflammatory agent. It has complexing ability.

Vlairin is a water-alcohol extract of the plants of the mountain Pamir-Ungeria containing a complex of polysaccharides. Vlairin helps to reduce the mutagenic effects of ionizing and ultraviolet radiation of cadmium salts and other heavy metals, accelerates the healing of wounds, including burns, and reduces allergic reactions, including dermatitis.

Amphoteric surfactant-betaine (cocamethylpropyl betaine, BETAVET NK-50K, VENUTZH RK-45, cocamidopropylsulfobetaine BETAVET 8H-K and others) has toxicological and dermatological properties.

Glycerin is used as a water-retaining and skin softening supplement.

The proposed detergent may also contain the following components to achieve certain goals: preservatives - to increase the shelf life of the products, dyes - to give various colors, well-known fragrances - to give a pleasant smell.

The proposed tool is prepared as follows.

Polyvinyl alcohol is soaked in water for 1-2 hours. To the resulting solution, CMC (aqueous solution) is added at a temperature of 15-20 ° C, then heated to 85-90 ° C and stirred until complete dissolution. Then add the calculated amount of glycerol and surfactant, mixing at a temperature of 40-45 ° C. Download samples of chitosan, citric acid, trilon B, aluminum alum at a temperature of 30-35 ° C, stirring. The introduction of fragrances at a temperature of 25-30 ° C.
