Abstract

The solution concerns the application of fat from bluefish /Alopex lagopus/ in a mixture with wheat germ oil. It has been found that this unsaturated oil improves the effect of fat from bluefish in cosmetic or washing preparations. This combination of fatty substances can be applied! in preparations for nails, for hair, for skin in various application forms.

Description

The invention relates to a cosmetic or washing preparation containing fat, which is characterized by a beneficial effect on the skin, high reabsorption capacity and stability of active ingredients.

In cosmetics and pharmacy, preparations used for application to human skin usually contain mineral oils of various viscosities as their fat component, which are not easily absorbed, as well as vegetable oils such as sunflower, soybean, almond, olive, and more recently also avocado, locust bean, etc. oils.

Of animal fats, alcohols obtained from sheep wool fat are commonly used, while the choice of oils of animal origin is very limited. For example, oils from the sebaceous glands of birds (higher esters of 2-ethylhexanoic acid) are known, as well as oil from the subcutaneous tissue of minks, the use of which in its native form is described in DAS 1,274,278 and OS patent 4,038,995 and US patent 2,954,325, the use of lipolytically cleaved fat in Czechoslovak AO 175,312. Recently, the use of other suitable raw materials, such as fat from river nutria, has been sought.

The essence of the invention is the use of the synergistic effect of refined blue-footed booger fat, which by its composition has a beneficial effect on human skin, and wheat germ oil. Due to the high content of unsaturated fatty acids oleic, linoleic, and especially palmitoleic /9 cis hexadecenoic acid/ and the content of vitamin E, the preparation containing betel nut fat and wheat germ oil is characterized by a beneficial effect on the skin.

Fat from foxes is a raw material of domestic origin, which is unused in animal production and is waste. The fat is obtained by refining the subcutaneous fat of animals. At a temperature of 20 °C, it is a yellowish to yellow liquid to semi-solid mass, which at a reduced temperature reversibly solidifies due to the content of solid components. Its characteristic properties and values are given in Table 1, where the values of fats from the subcutaneous tissue of mink and nutria are also given for comparison.

The high content of unsaturated fatty acids, which are subject to oxidation, requires the use of antioxidant agents. In addition to castor oil, wheat germ oil is present, which, in addition to vitamin A, also contains vitamin E /tocopherol/, which is a very effective antioxidant. The preparation contains 0.5 to 15.0 parts by weight of refined castor oil and 0.01 to 5.0 parts by weight of wheat germ oil.

The biological importance of unsaturated fatty acids lies primarily in ensuring the structural and functional integrity of biomembranes. Membrane lipids of the skin undergo peroxidation after exposure to substances from the external environment that induce the formation of free oxygen radicals. Aging of human skin cells and changes in the skin exposed to radiation are directly related to increased peroxidation of membrane lipids. The formation of oxygen radicals, corresponding to lipid peroxidation, can be monitored analytically. This process is regulated by antioxidants.

Of the natural antioxidants, vitamin E is the most effective, one molecule of which is able to protect 2,000 to 2,500 unsaturated fatty acid residues from oxidation. Vitamin E inhibits lipid peroxidation in the epidermis and thus has a positive effect on cell aging. Its presence in the proposed combination with subcutaneous fat from bluefish ensures the stability of this fat and, thanks to the excellent resorption of this combination, exerts its effect in epidermal microsomes. The use of vitamin E in the form of wheat germ oil is advantageous due to the presence of other substances important for the skin. The proposed combination is intended to strengthen or, in exposed conditions, help maintain the barrier protective function of the skin, which plays an important role in regulating the entry of toxic substances into the body.

Based on testing and clinical evaluation, as well as the composition, the advantageous combination of castor oil and wheat germ oil can be characterized as a highly effective fat component, stable and without adverse side effects, which can be used advantageously where there is strong degreasing or drainage of the skin, hair or nail plate due to the action of chemical agents, chemical and physical factors of the external environment /influence of polluted air, radiation/. This is the case, for example, when using a product for permanent hair curling in a strongly alkaline environment with reducing agents, when varnishing and removing nail polish, when using shampoos and detergents.

The wheat germ oil present, the amount of which is at least 2.0 t per amount of castor oil, supports, in addition to its antioxidant properties, the resorption ability of castor oil into the skin. Transepidermal resorption consists in the fact that the substance penetrates the stratum corneum, gets behind the Reln barrier and penetrates the entire surface into the deeper layers of the skin. Transepidermal resorption can be facilitated by some substances that act as so-called guiding substances. One of them is vitamin A, contained in wheat germ oil, and also the so-called essential fatty acids contained in both raw materials.
