After shave cream

 

(57) Abstract:

The invention relates to cosmetic and can be used in the manufacture of cosmetic products after shaving. After shave cream contains biologically active additive, which is a suspension of liposomes from phospholipids and lipids of animal and/or vegetable origin include them chloroformic extracts of nettle, chamomile, Hypericum, calendula and sage and base containing glycerin, vegetable oil, oleate PEG-400, propyl and methyl esters of peroxybenzoyl acid, paraform, ammonium salt Recoletos copolymer of acrylic acid and polyallylamine esters of pentaerythritol, perfume, dye and water, the components are taken in certain proportions. The cream has a prolonged action, penetrates deeply into the structure of the skin, relieves skin irritation and heals cuts.

The invention relates to medicine, namely cosmetics, and can be used in the production of gel-like cosmetic products for skin care after shaving.

Feature of cosmetics for skin care after shaving is set not only nutritious,positive and anti-allergic properties.

In the formulation known creams to care for skin after shaving actively used extracts of plant materials due to their low cost, availability, and a wide spectrum contained useful components. Known use in the formulation of creams, after shave hydro-alcoholic extracts of nettle, yarrow, mother-and-stepmother, oats, cranberries, etc /A. S. USSR N 1304816 And 61 To 7/18, 23.04.87, bull. N 15; A. S. USSR N 1421344, a 61 K 7/06, 07.09.88, bull. N 33; A. S. USSR N 1708342, a 61 K 7/06, 30.01.92, bull. N 4/.

The disadvantage of these creams is not enough to penetrate deep into the skin structure of biologically active components, which reduces the effectiveness of the cream. The effect of therapeutic components short-lived.

The closest to the claimed purpose is the means to care for the skin, especially after shaving. /Pat. RF N 2062092, a 61 K 7/06, 20.06.96, bull. N 17/.

Recipe tools provides high biological activity through the use of selected complex of water-soluble extracts of plant materials according to the principle of synergy and redundancy required properties.

The composition as a dietary Supplement contains a water-spiroperidol extracts tysyachelistnik willow, oak, poplar branches, black currant, roots of Burnet and toffee, fruit cherry. The cream consists of stearin, lanolin, menthol, vegetable oil, emulsive wax, preservatives, triethanolamine, distilled monoglycerides, ethyl alcohol, perfume and water.

Synergistic effect of biologically active additives is provided by the mutual action of its components.

In particular, the effect of relieving irritation of the skin after shaving is achieved by azulene contained in yarrow, wormwood, together with sesquiterpenoids contained in the extract of wormwood, yarrow, calendula, branches of poplar, oregano. Action azulenes and sesquiterpenoids increases tannins parameterinfo number contained in extracts of yarrow, nettle, sage, calendula, sweet clover, black currant, oak, motherwort, Burnet, lemon balm, cherry, willow, sainfoin, poplar, oregano, cornflower.

Providing hemostatic properties, reducing the permeability and fragility of capillaries, increase the elasticity of their walls is achieved due to the presence of flavanoids with P-vitamin activity of extracts of yarrow, nettle, kalaiselvam, capillary action has on the skin carotenoids (provitamin A) of calendula, yarrow, nettle, lemon balm, sage, vitamins C, PP, of yarrow, nettle, sage, oak, motherwort, Burnet, cherry, poplar.

The presence in the extracts of nettle, thyme, clover, oak, sainfoin Tocopherols (vitamin E) creates a complex with tannins from nettle, poplar sufficient antioxidant effect, which inhibition of peroxidation reactions and the formation of free radicals - the destroyers of intercellular membranes.

Contained in extracts of yarrow, nettle, poplar, sage, clover essential oils and alkaloids from motherwort, Burnet, nettle, cornflower and saponins from calendula, motherwort, Burnet, fireweed have on the skin tonic effect, increase metabolism, give the skin elasticity.

Organic acids (oxalic, citric, lactic, malic and other) from yarrow, nettle, Burnet, cherry, poplar, willow, stimulates the metabolic processes that cleanse the pores of the skin, have antibacterial properties.

The steroids contained in nettles, prevent skin aging, promoting the renewal glue the connection in the formulation of extracts of yarrow, nettles, calendula, willow, wormwood. Introduction extracts of other plants creates additional reinforcing effect.

Despite strong biological activity, requiring careful quantitative balancing of components, the cream has disadvantages, namely, that the biologically active components are not sufficiently penetrate deeply into the structure of the skin, the cream has a short-term effect.

The aim of the invention is to improve the efficiency and achievement of prolongirovannomu of action of biologically active components due to deep penetration in their skin texture.

This objective is achieved in that the after shave cream contains biologically active additive, which is a suspension of liposomes from phospholipids and lipids of animal and/or vegetable origin include them chloroformic extracts of nettle, chamomile, Hypericum, calendula and sage and base containing glycerin, vegetable oil, oleate PEG-400, propyl and methyl esters of peroxybenzoyl acid, paraform, ammonium salt Recoletos copolymer of acrylic acid and polyalloy esters of pentaerythritol, perfume, dye and water, the next sod is R>
the oleate PEG-400 - 1,8-2,0

propyl ether, peroxybenzoyl acid - 0,08-0,1

methyl ether of peroxybenzoyl acid - 0,2-0,3

In relation to the prototype of the proposed formulation of the cream after shave has the following salient features.

Use as biologically active additives to the suspension of liposomes from phospholipids and lipids of animal and/or vegetable origin include them chloroformic extracts of nettle, chamomile, Hypericum, calendula and sage.

The use of chloroform extracts of nettle, chamomile, Hypericum, calendula and sage allows you to extract not only the complex set of biologically active dietary components to give the cream of the required properties (azulene, sesquiterpenoid, tannins, flavonoids, carotenoids, Tocopherols, essential oils, alkaloids, saponins, organic acids, steroids), but also phospho - and glycolipids.

Other extraction methods do not ensure the complete removal of lipatnikov and other components of medicinal herbs in the membrane of liposomes when they are received using reverse phase.

Thus, in the membranes of liposomes balanced lipids of plant and animal origin and complex biologically active components.

Known for high biological activity of lipids in drug delivery into the cells of the body, restoring the lipid composition of cell membranes, which occurs when the disruption of metabolic processes. The liposomes fuse with the cell membrane, while the lipid component of the liposome embedded in the cell membrane, a water-soluble drug penetrates into the cytoplasm of a cell /C. M. Shvets, Y. M. Krasnopolsky, West. Acad. the honey. of Sciences of the USSR, 1990, No. 6, S. 19-28/.

Injection of liposomes in the cell membrane and the gradual withdrawal of drugs provides prolongation of action of biologically active substances.

Use as a structural component of a copolymer of acrylic acid and polyallylamine esters of pentaerythritol not only provides a gel-like consistency of the cream, but the conditions for the formation of coherently-dispersed system by polycondensation of the components of the framework with polar lipids belayneh membranes of liposomes, respectively, the stable distribution is the firmness of the biologically active additives are used, the suspension of liposomes incorporating therapeutic components of a-tocopherol, an aqueous extract of a ginseng /Pat. RF N 2036637, a 61 K 7/00, 09.06.95, bull. 116; U.S. Pat. RF N 2045261, a 61 K 7/00, 10.10.95, bull. N 28/.

On the market of cosmetic products appeared cream Capture firm Christian Dior Parfum, Paris, which contains hydrolyzed collagen, hyaluronic acid, liposomes based on soybean lecithin containing extract of thymus /Nasyrova N. Y. and the other, West. Acad. the honey. of Sciences of the USSR, 1990, 16, S. 8-19/.

These creams do not contain biologically active ingredients that give the required properties for the cream after shaving.

The possibility of practical implementation of the inventive formulations is illustrated by a specific example.

Example 1. In the mixer pour distilled water based filling apparatus 70% and when the stirrer fall asleep ammonium salt Recoletos copolymer of acrylic acid and polyallylamine esters of pentaerythritol at a rate of 10 g of copolymer per 1 liter of solution, add paraform of 0,03% of the total volume of the finished product and methyl ester of peroxybenzoyl acid at the rate of 0.2% of the total volume of the finished product. The mixture was stirred at 20-25oC for 20-30 minutes Received a jelly-like mass is forced by a pump through the double-layer is ri running at a speed of 60 rpm mixer add the glycerin from the calculation of the 3.5% of the total volume of the finished product, the oleate PEG-400 from the calculation of 2.0% of the total volume of the finished product, vegetable oil (olive, cottonseed, sunflower refined) at the rate of 2.0% of the total volume of the finished product and propyl ether, peroxybenzoyl acid at a rate of 0.1% of the total volume of the finished product. The mixture is heated in the reactor to 60-70oC and stirred for 30-40 minutes and Then the mixture is cooled to 40oC and the reaction mass is slowly poured into a suspension of liposomes containing chloroform extract of herbs at the rate of 10% suspension of the total product, add dye and fragrance at the rate of 0.001% and 0.2% of the total volume of the finished product, respectively.

The resulting mass is stirred for 30-40 minutes, cooling it to 30oC and sent for filtering and packing

A chloroform extract of the herb is prepared as follows. Dried and crushed herbs of nettle, chamomile, Hypericum, calendula, sage mixed in equal amounts and incubated under a germicidal lamp for 3 hours Then the mixture of herbs is poured chloroform in the ratio of 1:20, the suspension is stirred and insist in a dark place for 2-3 days. After extraction, the suspension is stirred and separated supernatant. Sulpture cream optimally achieve the desired effect

The decrease in the content structure-forming component does not provide the necessary consistency of the cream and its stability, the increase in the concentration above the proposed limits leads to a hard consistency, enhance the content in the product of acrylic acid.

The decrease in the content below the proposed components of a fatty basis of biologically active additives affects the biological and nutritional quality of the cream, and the increase is impractical because the effect is almost not changed.

The cream has a pleasant smell, soft and smooth consistency, evenly glides on skin, absorbs quickly without leaving an oily sheen.

Test pilot batches of cream in the Centre and cosmetic correction of RAS and in Pyatigorsk pharmaceutical Academy has shown positive results.

The content of total surface lipids after using the cream rinse skin increased by 10% compared to baseline levels and skin elasticity increased by 8%. Quickly relieves skin irritation after shaving, saulawa cuts the skin and stops the bleeding.

The use of the claimed composition of the cream will allow you to organize mass produced the cally active additives of plant origin, glycerin, vegetable oil, preservatives, flavoring and water, characterized in that, as a dietary Supplement, it contains a suspension of liposomes from phospholipids and lipids of animal and/or vegetable origin include them chloroformic extracts of nettle, chamomile, Hypericum, calendula and sage, as preservatives - propyl and methyl esters of peroxybenzoyl acid and further comprises ammonium salt Recoletos copolymer of acrylic acid and polyallylamine esters of pentaerythritol, polyethylene glycol, paraform and dye at the following content, wt.%:
