NO842674L - COSMETIC PREPARATION - Google Patents

Description

The invention relates to cosmetic preparations, and especially creams, lotions and liquids for moisturizing the skin.

Many cosmetic preparations of the cream, lotion and liquid type

is commonly used. There is considerable variation in the vegetable-specific formulations that form the oil and water phases of such preparations. Mineral oils, animal oils and vegetable oils are all used in cosmetic creams and lotions of the emulsion type. In addition to such oils, other emollients and surfactants have been incorporated into the emulsions, including stearates such as potassium stearate, glycol stearate, sodium stearate, PEG 40 stearate and glyceryl stearate, laurates such as sodium laurate and potassium laurate, alcohols such as cetyl alcohol and lanolin alcohol, triethanolamine, myristates such as isopropyl myristate, sodium myristate and potassium myristate, cetyl palmitate, cholesterol, stearic acid and sorbitan sesquileate. Stabilizers such as methylparaben and propylparaben are usually incorporated into the cosmetic preparations.

One purpose of the invention is to provide an improved cosmetic preparation of either liquid or emulsion type,

as the improved preparation is very effective in moisturizing the epidermis, softening the skin, improving the texture and feel of the skin and reducing superficial and deep wrinkles in the skin.

This is achieved according to the invention by providing a cosmetic preparation of cream, lotion or liquid type, in which it is incorporated from approx. 0.1% up to approx. 1% gibberellic acid and from approx. 0% up to 5% lysine. Lysine is preferably used in the preparation L-lysine, which is a naturally occurring form of lysine. However, the dextro isomer can be used as well as analogues of lysine, such as hydroxylysine. The improved preparation can also contain from approx. 0.01% to 5% gliadin, from approx. 0.005% to 1% ascorbic acid, from approx. 0.01% to 5% urea and up to 1% calcium.

It has been found that the effect of liquid water-based preparations

and water-oil emulsion-type preparations, can be significantly and markedly increased with respect to moisturizing the epidermis, softening the skin, improving the texture and feel of the skin and in reducing superficial and deep wrinkles in the skin by incorporating the above-mentioned substances in the cosmetic preparations.

Cosmetic preparations, whether creams, lotions or liquids, can be prepared according to the invention from countless basic cosmetic ingredients which are well known. Such bases can include emulsions containing different softening ingredients. Lanolin or other oils from the group consisting of animal oils, vegetable oils and mineral oils, are emulsified with water in the usual way. In addition to the oils, other softening and surfactants such as those mentioned above can be incorporated into the emulsions in a known manner. Stabilizers and preservatives may be included

the cosmetic preparation in the usual way.

The essential aspect of the invention does not lie in the composition itself in and of itself, and any of many basic formulations or composites can be used

nings of water or the emulsion type previously used in cosmetic skin preparations. The essential thing about the invention is the incorporation of specific substances in the cream, lotion or liquid preparation as essential and mar-

kert increases the effect of the cosmetic preparation in moisturizing the epidermis, softening the skin, improving the texture and feel of the skin and reducing superficial and deep wrinkles in the skin. Previously, it was not known to use the combination of specific active substances as stated here.

According to the invention, a cosmetic preparation with a very good effect is obtained. The cosmetic preparation comprises a cream, lotion or liquid base, in which approx. 0.01% up to approx. 1% gibberellic acid and from approx. 0% up to approx. 5% lysine. In addition to gibberellic acid and lysine, the cosmetic preparation can also contain up to approx. 5% gliadin, up to approx. 1% ascorbic acid and up to 5% urea. Preferred concentrations of the latter substances when they are used in the cosmetic preparation are from approx. 0.03% to 1% gliadin, from approx. 0.01% to 0.05% L-ascorbic acid and from approx. 0.03% to 1% urea. The cosmetic preparation can too

in addition to the above substances contain up to approx. 1% calcium. All percentages are weight-%.

As an exemplary embodiment, a specific formulation of a preferred embodiment of a cosmetic cream according to the invention is the following:

Using the above-mentioned composition of the cosmetic cream, comparative tests were carried out, where 50 women between the ages of 24 and 68, all of whom were in good health without any skin diseases, tried the cream according to the invention compared to four commercially available cosmetic skin creams. The women were divided into groups of 10 people. In groups of four, each woman was given one container of cream in accordance with the invention and one container of commercially available skin cream. In the fifth group, the women were given a container with cream according to the invention and a container with a cream base of the test product according to the invention, i.e. the same cream which did not contain lysine, urea, gliadin, ascorbic acid and gibberellic acid.

The only markings on the container given to the women were instructions to apply the cream from the respective containers to one side of the face with the cream in the other container applied to the other side of the face. All subjects were assessed after one month. Almost without exception, the women reported a significant improvement in the visual appearance of the side of the face to which the cream of the invention had been applied compared to the side to which the commercially available skin creams and cream bases had been applied. The main part of the test subjects also reported

about a significant improvement in the sensitivity conditions on

the side of the face where the cream according to the invention was applied compared to the side where the commercially available skin creams and cream bases had been applied. The test subjects, when asked to choose which cream they preferred, chose almost all of the products according to the invention.

Modifications can of course be made to the object of the invention without exceeding the scope of the requirements.
