Description

 The invention relates to cosmetics, namely to hygiene products for skin care.

Known lotions for facial skin ("Cucumber", "Orange", "Moscow Lights", "Pink Water", "Dewdrop") containing infusions of medicinal plants in combination with various additives and having anti-inflammatory, whitening, tonic properties [1]
A disadvantage of these known agents is a narrow spectrum of their biological effects.

 Closest to the claimed composition in technical essence and the achieved result is a lotion containing cucumber juice, boric acid, glycerin, ethyl alcohol, perfume, dye, water and has a refreshing, tonic, cleansing and whitening effect. It is accepted by us as a prototype. The disadvantage of this cosmetic product is also a narrow spectrum of biological effects.

In order to increase the biological value, improve the therapeutic and prophylactic properties, expand the spectrum of biological activity, as well as replace artificial components (dye and perfume) with natural ones, a lotion has been proposed that, in addition to boric acid, glycerin, ethyl alcohol, water, contains chamomile pharmacy water extract -alcohol and the drug sanguirytrin in the following ratio of these components, wt. Chamomile extract pharmacy water-alcohol 8.0-12.0 Sanguiryrin 0.005-0.01 Boric acid 0.3-1.0 Glycerin 4.0-5.0 Ethyl alcohol 400-50.0 Purified water Up to 100
Hygienic lotion is prepared as follows.

In a glass reactor heated by steam, 40-50 kg of ethyl alcohol are fed with a working stirrer, the calculated amount of purified water; a solution of 0.3-1.0 kg of boric acid in water in a ratio of 1:25; a solution of 0.005-0.01 kg of sanguitrin in water in a ratio of 1: 300; a mixture of 4.0-5.0 kg of glycerin with an equal amount of water and 8.0-12.0 kg of chamomile water-alcohol pharmacy extract. The mixture is heated to a temperature of 35-40 ^{° C,} stirred for 30 min, after which the liquid is poured into the vessel for settling. Settled for 48 hours and filtered. The filtrate is the target product hygienic lotion, which is Packed in glass bottles with screw neck and corked with screw-on plastic caps.

 Glycerin is introduced into the lotion as a universally recognized skin softener in the amount of 4.0-5.0. The introduction of glycerol in an amount below the selected limit (4.0%) does not ensure complete dissolution of the components. The introduction of glycerol in amounts above the upper limit (5.0%) leads to excessive fat content of the lotion, which causes unpleasant subjective sensations when using the lotion.

 As an anti-inflammatory and flavoring agent, chamomile extract in the amount of 8.0-12.0% was introduced into the lotion formulation. The introduction of chamomile extract in an amount below the selected limit (8.0%) does not provide a flavoring effect. The introduction of chamomile extract in an amount above the selected limit (12.0%) leads to a sharp odor.

 Sanguirythrin is introduced into the lotion formulation as an antimicrobial agent, which at the same time gives a pleasant yellow color to the lotion, in an amount of 0.005-0.01%. When using sanguirythrin in an amount below the selected limit (0.005%), the necessary lotion color is not achieved. When using sanguirytrin in an amount above the selected limit (0.01%), excessive drying of the skin is observed.

 Boric acid was introduced into the lotion as a keratoplastic agent in an amount of 0.3-1.0%. The introduction of boric acid in an amount above the upper limit (1.0%) leads to a skin-tightening effect. The introduction of boric acid in an amount below the selected limit (0.3%) does not provide an effect.

 Ethyl alcohol in the amount of 4.0-50.0% was introduced into the lotion formulation in accordance with the general requirements of the technical conditions for cosmetic lotions. The introduction of ethyl alcohol in an amount below the selected limit (40.0%) does not provide a dissolving effect. The introduction of ethyl alcohol in an amount above the selected limit (50.0%) is not economically feasible.

 The main components of the lotion are chamomile extract and sanguirythrin, which have high biological activity. Chamomile extract causes an anti-inflammatory effect. The drug sanguirytrin is used as an antimicrobial agent. The combination of sanguine and biologically active substances of chamomile in their mixture with the addition of glycerin, alcohol, boric acid led to the presence of a new combination of properties in the lotion.

 Clinical radiation of the lotion showed that it does not cause irritation or an allergic skin reaction, has a pleasant smell, causes a feeling of freshness of the skin, cleanses the skin well, a decrease in sebum secretion and good drying properties of the lotion are noted. The use of the lotion for patients with acne revealed a skin cleansing, drying and anti-inflammatory effect. With regular use of the lotion, a significant clinical improvement was noted during the course of the disease (acne), fresh acne rash practically did not appear). Thus, a clinical study of the lotion showed that it has a cleansing, anti-inflammatory, degreasing effect on the skin, has a pleasant smell, does not cause irritation and allergies.

 Examples of component composition are given in the table.

Purified water up to 100 kg
Examples 1-3 correspond to the declared limits, examples 4-5 correspond to transcendental values.

 The novelty of the claimed lotion is that it contains chamomile extract and the drug sanguirytrin. In comparison with the prototype, special components of perfume and dye are not introduced into the lotion. A pleasant yellow color to the lotion is provided by its own coloring of sanguirythrin, the natural smell of chamomile extract.

 The inventive step of the claimed lot is provided by the fact that the complex of active biologically active components of chamomile extract and sanguirythrin preparation combined with selected amounts of glycerin, boric acid and ethyl alcohol provides for the manifestation of new properties. Replacing the artificial components of perfume and dye with natural ones eliminates the possibility of a harmful effect on the skin: irritation or an allergic reaction, when applying the lotion a feeling of freshness of the skin appears.

 PRI me R 1.

In a glass reactor with a stirrer, heated by steam, 40 kg of ethyl alcohol are fed with the stirrer operating; 30.7 l of purified water, a solution of 0.3 kg of boric acid in 7.5 l of water; a solution of 0.005 kg of sanguirytrin in 1.5 l of water; a mixture of 4.0 kg of glycerin with 4.0 l of water; 12.0 kg of chamomile extract. The mixture is heated to a temperature of 45-50 ^{° C,} stirred for 30 minutes and drained fluid in the settling tank. Settle until completely clarified (48 hours). The solution was decanted and filtered. The filtrate, which is the target product, is packaged in glass bottles.

 PRI me R 2.

 The preparation of the lotion is carried out in the same manner as described in example 1, loading the following amounts of components sequentially into the reactor: 43 kg of ethyl alcohol; 22.6 liters of purified water; a solution of 0.5 kg of boric acid in 12.5 l of water; a solution of 0.008 kg of sanguirytrin in 2.4 l of water; a mixture of 4.5 kg of glycerin with 4.5 kg of water and 10 kg of chamomile extract.

 PRI me R 3.

 The preparation of the lotion is carried out as described in example 1, sequentially loading into the reactor the following amounts of components: 50 kg of ethyl alcohol; 3 l of purified water; 1.0 kg of boric acid in 25 l of water; a solution of 0.001 kg of sanguirytrin in 3 l of water; a mixture of 5.0 kg of glycerol with 5.0 l of water; 8.0 kg of chamomile extract.

 Due to the cleansing, anti-inflammatory and degreasing effects of the skin, the lotion is recommended to be used not only as a hygienic, but also as a therapeutic and prophylactic agent for acne and oily seborrhea.

 The developed lotion has passed clinical trials and is recommended for industrial production as a cosmetic product.
