Abstract

The anti-wrinkle cosmetic preparation, made on the basis of an o/w or w/o emulsion, consists of an active part containing scleroprotein, in particular elastin and vitamin E in a weight ratio of 1 to 3:1, further of an aqueous part and of a fatty part, the weight ratio of these three parts being 1:3.5 to 20:3.5 to 20. A mixture of elastin and collagen can also be used as the scleroprotein. The aqueous part contains higher alcohols Ci4 to Csi' and sugar esters emulsified in triethamolamine and polyglycol ether, the fatty part then contains sugar glycerides emulsified in stearic acid and stearic acid monoglyceride.

Description

The invention relates to a cosmetic preparation against the formation of wrinkles on the skin, made on the basis of an o/w or w/o emulsion, the active part of which consists of a scleroprotein, in particular elastin, in a mixture with vitamin E, dissolved in a mixture of an aqueous and fatty component.

It is known that one of the protective abilities of the skin is its ability to absorb and retain moisture to a certain extent. As a result of the practically constant, adverse effects of the environment on the skin, such as the influence of the weather, the working environment and, last but not least, the necessary frequent washing, especially with the use of a product with a significant extracting effect, this inherent protective ability of the skin is significantly reduced. This leads to systematic dehydration of the skin and the associated adverse changes in its surface. Cosmetic preparations are known that help reduce the consequences of dehydration by supplying the skin with, or helping to maintain, a certain level of moisture.

These well-known cosmetic preparations, usually of the w/o or o/w type, contain as an active substance, e.g. sugar esters of lauric and palmitic acids (see Czechoslovak patent certificate number 177 783) or -pirocaine (see German patent number

814,315).

Some other known preparations solve the problem of dehydration by containing, in addition to the usual components, such as extracts from various plants, cyclic carboxylic acids and their salts (see, for example, German patent number

404 073 and d.j, oat flour, or wheat flour, etc.

These known cosmetic preparations usually penetrate the skin well and achieve very favorable results.

The disadvantage of some of these known preparations, such as preparations containing procaine, is that a significant number of people have difficulty tolerating these preparations, while other preparations, despite having a significant beneficial effect on the skin, have still not been able to prevent the formation of wrinkles.

Recent research has confirmed that the formation of wrinkles, especially around the eyes, forehead and neck, occurs not only due to loss of moisture in the skin, but primarily as a result of loss of skin elasticity. This change occurs especially during aging or with more permanent, excessive exposure to light or sunlight.

In these cases, there is a continuous cross-linking of collagen in the dermis, which in turn causes the elastic fibers to thicken. These fibers become thicker and more fragile, and they lose their elastic properties.

The reason for ^this change in elastic fibers is the increase in lipids in the hydrophobic groups of elastin, which is the main protein in elastic fibers. The consequence of this change is the aforementioned loss of elasticity and moisture of the tissue and the resulting formation of wrinkles.

' These consequences of the aging process, or more permanent excessive exposure to light, are attempted to be eliminated by some known cosmetic preparations containing collagen (see, for example, German patents No. 2,514,844, further No. 2,064,604 or No. 2,909 6-43, or French patents No. 8,101,971 or No. 7,705,765).

However, for the most part, these cosmetic preparations are not adapted for permanent use, -because they can be applied as a mask or powder, or as a shampoo or rinse water for the hair (see Japanese patents No. JP 53 026 333 or No. JP 51082 737).

Therefore, a significant disadvantage of many of these known cosmetic preparations is that they do not allow their application at any time of day and their long-term effect on critical areas of the skin on the face.

The disadvantages of known cosmetic preparations against the formation of wrinkles on the skin are eliminated by the cosmetic preparation according to the invention, made on the basis of an o/w or w/o emulsion, the peculiarity of which is that it consists of an active part containing scleroprotein, in particular elastin and vitamin E in a weight ratio of 1 to 3:1, and a water-based fatty part, the weight ratio of these three parts being 1:3.5 to 20:3.5 to 20.

In the active part, a mixture of elastin and collagen can also be used as the scleroprotein. The aqueous part contains, according to the invention, 6 to 12 parts by weight of a higher alcohol C14 to C18, such as, for example, ^myristyl alcohol or cetyl alcohol, together with 2 to 4 parts by weight of lauric acid or p-almitic acid sugar ester or a mixture thereof, emulsified in 1 part by weight of triethanolamine and 2 parts by weight of polyglycol ether and up to 90 parts by weight of drinking water, with the optional addition of another component, such as, for example, propylene glycol.

The fatty part then, according to the invention, contains 1 part by weight of coconut oil sucroglyceride, emulsified in 8 parts by weight of stearic acid and 6 parts by weight of stearic acid monoglyceride and up to 90 parts by weight of vaseline oil, with the optional addition of another component, such as beeswax.

The new, higher effect of the cosmetic preparation against the formation of wrinkles according to the invention is achieved primarily by the above-mentioned combination of elements of the active part, where one element, vitamin E, supports proper blood circulation in the skin and thus prepares it for optimal absorption of the second element, scleroprotein, in particular elastin, which is the main protein part of elastic fibers in the skin and which, after prolonged, repeated application, causes the formation of new elastic fibers in the skin tissue.

Sugar esters of lauric acid and palmitic acid from the water part together with coconut oil sugar glyceride from the fatty part effectively help the said active part to prevent skin dehydration.

At the same time, the composition of the aqueous and oily parts of the preparation according to the invention facilitates pleasant spreading of the preparation and its rapid absorption. The raw materials used and their combinations according to the invention enable permanent, repeated application of the cosmetic preparation without restrictions, at any time. The preparation is tolerated without difficulty even by people with extremely sensitive skin.

' A particularly favourable fact is that the cosmetic preparation according to the invention is easily tolerated even on the skin in the immediate vicinity of the eyes, which is particularly prone to the formation of wrinkles. When testing the cosmetic preparation according to the invention, more than 50 people of various ages from 18 to 70 years were tested. In practically all of the test subjects, a significant improvement in the condition of the skin could be observed after 2 months of daily use of the preparation. In many cases, a visible improvement in the condition of the skin could be noted after 3 weeks of daily use of the preparation.
