Description

Technical field

The invention relates to the field of cosmetics, in particular to a moisturizing composition that can be used in the manufacture of toilet soap, providing extra-moisturizing effect.

State of the art

Increased attention to the cosmetic condition of the skin after washing determines a higher level of content in the modern toilet soap of exhaling, softening and hydrating skin substances.

The prior art there are many moisturizing additives introduced into the composition of toilet soaps. So in SU 1599018 A1, 10/15/1990 a toilet soap is described, in which to increase the softening and regenerating properties of the skin, a complex of oil extracts of horsetail grass and lingonberry leaves and a 50% solution of protein hydrolyzate are introduced.

In RU 2163256 C1, 02.20.2001 a toilet soap of a classical composition is described, additionally containing aloe extract in propylene glycol, which helps to heal cuts and scratches on the skin, softens and moisturizes the skin.

US 5658868 A, 08/19/1997, describes a soap composition for cleansing and conditioning skin and hair, containing cleansing and conditioning / moisturizing agents such as aloe vera and wheat germ oil.

WO 2005/039525 A1, 05/06/2005, describes a skin care and cleansing composition containing anionic surfactants and a product obtained from oilseed.

JP 60-112708 A, 06/19/1985 (see abstract) describes a skin moisturizer with a high moisturizing effect, which can be used in cosmetics in the composition of soaps, creams, lotions for the face, powder, lipstick, etc. The humidifier contains, as an active component, 0.1-0.3% polysulfate of chondroitin sulfuric acid, extracted from animal organs.

WO 99/37744 A1, 07.29.1999 describes a skin cleansing soap containing a surfactant mixture and a liquid hydrophobic emollient oil or humectant, or a mixture thereof, where the emollient oil is selected from C ₈ -C ₂₄ hydrocarbon oils, liquid diglycerides, triglycerides, vegetable oils, or derivatives thereof, silicones, sterols, or lanolins, and the humectant is selected from glycerols, glycerol, C ₁ -C ₁₀ alkylene glycols or polyalkylene glycols.

However, some of the known moisturizers or mixtures of moisturizing components used in soap compositions are inaccessible, others do not allow to achieve the desired effect of moisturizing and softening, without losing the necessary physical properties of the soap.

The closest technical solution is toilet soap with a nourishing cream containing sodium salts of fatty acids of edible fats or sodium salts of fatty acids of palm oil and sodium salts of fatty acids of coconut oil (soap shavings); sodium chloride; pigment titanium dioxide; citric acid; antioxidant "Antal P-2"; perfume composition, water and nourishing cream as a moisturizing and nourishing additive (RU 2146126 C1, 03/10/2000). As a nutritious cream introduced into soap shavings, the following composition is used with a ratio of components, wt.%: 1.00-4.00 fats for cooking, confectionery and baking industry; 2.00-4.00 ceresin grades 60, 70, 75, 80; 7.00-10.00 anhydrous lanolin; 2.50-4.00 pentol; 40.00-52.00 sunflower oil of high oleic deodorized refined or olive refined, or cotton salad deodorized, or from fruit seeds and almonds, or soy refined deodorized; 0.2 preservative and the rest is drinking water. The disadvantages of the known moisturizing agent include the use of a preservative in the composition, which is undesirable. In addition, toilet soap containing the indicated nourishing cream in a rather large amount dissolves too quickly and swells when used, which leads to uneconomical consumption of soap, as well as a decrease in the washing effect and ineffective moisturizing and softening of the skin.

The present invention is the creation of a new moisturizing composition for soap, providing a high level of moisturizing and softening the skin, which allows you to create on its basis high-quality inexpensive toilet soaps that have not only excellent cosmetic properties, but also high consumer qualities - high hardness, lower consumption rate and resistance to deformation.

The technical result that can be obtained by implementing the present invention is to increase the emollient and moisturizing effect on the skin when using the claimed moisturizing composition, as well as to reduce the dissolution and swelling rate when using toilet soap containing the described moisturizing composition, which at the same time has extra moisturizing and softening action.

This problem is solved by creating a new moisturizing composition for soap containing in wt.%:

cosmetic cream with oil wheat germ 1.5-2.5 Shea Butter 3.0-5.0 C ₈ -C ₁₈ saturated fatty ester acids with several branched chains 2.0-3.5 water up to 100.

In another embodiment (embodiment) of the present invention, a moisturizing composition for soap, contains in wt.%:

cosmetic cream with oil wheat germ 1.5-2.5 Shea Butter 1.0-1.5 C ₈ -C ₁₈ saturated fatty ester acids with several branched chains 1.5-2.5 water 13.5-41.0 coconut oil up to 100.

Additionally claimed moisturizing composition may contain up to 10.0 wt.% Non-ionic surfactants (surfactants), such as glycosides C ₈ -C ₁₆ fatty alcohols, which have excellent foaming properties and good dermatological characteristics. The use of decyl glycoside is preferred.

The optimal combination of these ingredients in the declared amounts allows you to get a moisturizing composition with high cosmetic properties - softening, tonic and stabilizing, and also allows you to save more moisture in the skin.

The components that make up the soap perform the following functions.

Cosmetic cream with wheat germ oil contains vitamin E, has a regenerating and anti-aging effect. Using a cosmetic cream with wheat germ oil in an optimally selected amount allows you to gently cleanse, moisturize and nourish the skin.

Shea butter is a refined, deodorized vegetable fat obtained from the fruits of the oil tree by extraction and fractionation. The product is a natural oil of the fruits of the oil tree and contains glycerides of natural fatty acids obtained from the fruits of the oil tree by a special method of soft fractionation. Shea butter is an excellent natural fattening substance with a very weak characteristic odor. A distinctive feature of the product is a high content of unsaponifiable substance (triterpene alcohol, sterols), as a result of which the product has a medicinal and emollient effect. In addition to the cleansing, protective and healing properties, shea butter softens the skin and prevents its excessive dehydration.

C ₈ -C ₁₈ saturated fatty acid ester with several branched chains has a positive effect on skin sensations and skin hydration, increases foaming and stability of toilet soap foam, while being a good plasticizer, which prevents soap cracking. Ethylhexyl ethylhexanoate is particularly preferred as a C ₈ -C ₁₈ saturated multi-branched chain fatty acid ester.

Coconut oil is an integral part of the fat mixture for toilet soap and other soap preparations. It significantly increases their foaming ability and contains caprylic, lauric, myristic, palmitic, palmitiolenic, stearic, oleic, linoleic acids.

The next object of the invention is a toilet soap containing the above moisturizing composition for soap (or the first option or the second) and an effective amount of the usual components for toilet soaps.

Thus, it is preferable to use a soap containing bleaching agents, Antal P-2 plasticizer and stabilizer, citric acid, di- or tetrasodium salts of ethylenediaminetetraacetic acid, perfumes, sodium fatty acids of palm and coconut oils and the claimed moisturizing composition (or first or second), in the following ratio of components, wt.%:

bleaching agents 0.1-0.5 Antal P-2 0.1-0.5 citric acid 0.01-0.1 di- or tetrasodium salts ethylenediaminetetraacetic acid 0.01-0.1 glycosides C ₈ -C ₁₆ fatty alcohols up to 1.0 moisturizing soap composition 20.0-25.0 perfumes 0.5-2.0 fatty acid sodium salts palm and coconut oils up to 100.

The optimal combination of these ingredients in the declared amounts and a new moisturizing composition for soap allows you to get a toilet soap simultaneously with both high cosmetic properties - emollient, tonic and moisturizing effect on the skin, as well as consumer ones - high washing ability and economy when using it.

The additives that make up the soap perform well-known functions. A bleaching agent is added to impart purity to the color of the bar of soap. As a bleaching agent, the soap contains titanium dioxide pigmented or whitened zinc dry and optical brightener, which is introduced into the composition of the soap to enhance the brightness of the color of the piece.

As a stabilizer and plasticizer, the soap contains Antal P-2, which is a liquid of complex composition containing active substances, a plasticizer, an antioxidant, and a preservative (TU 64-19-31).

Di - or tetrasodium salts of ethylenediaminetetraacetic acid are included in the composition of the claimed soap as a complexing additive.

Citric acid is added to maintain the concentration of hydrogen ions (pH) of the agent within the required limits and as an amplifier of the antioxidant properties of the stabilizer introduced.

Soap shavings are sodium salts of fatty acids from fatty raw materials for toilet soaps.

The toilet soap of the present invention is characterized by the presence of gloss and smoothness, it foams well, is resistant to deformation and has increased foaming and washing abilities, as well as effectively softens and moisturizes the skin.

The following examples illustrate the invention without limiting its scope.

A moisturizing composition is obtained by mixing the components. The composition and basic ratios of components of moisturizing compositions are presented in table 1.

To assess the softening and moisturizing properties of the claimed moisturizing compositions for soap, the performer prepares the products immediately before the washing procedure, applying from 0.1 to 0.5 g of the product either directly on the skin, or on a moistened towel or any other applicable material. Then carry out the washing procedure. An assessment scale of 0 to 5 is used. Assessment includes a combination of subjective assessments (visual assessment of the skin condition by experts), as well as objective results, i.e. biophysical measurements using instruments to quantify the effect of a moisturizer on the function of the skin barrier and on the skin's ability to retain moisture. To assess the test sites for dryness and redness, a test is used to measure the rate of transepidermal water loss after treatment. Measurement of transepidermal water loss to verify the integrity of the skin barrier is carried out at each test site using the Servomed, EP1 and / or EP2 evaporor at the beginning (base value) and at the end of the product application phase or at the time of its termination (final value). Two consecutive fifteen-second measurements are taken per test site for each assessment of transepidermal water loss followed by a thirty-second equilibration period. The conductivity of the skin is measured using a SKICON-200 device with an MT-8C sensor, and / or the capacitive resistance of the skin is measured using a Corneometer at the beginning (base value) and at the end of the product application phase or at the time of its termination (final value). These methods provide an objective measurement of hydration. Three consecutive measurements are made for each test site and the obtained data are averaged. Estimates are presented in table 2.
