DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a cosmetic composition.
BACKGROUND ART
In the past, cosmetic compositions such as creams were composed so as to mimic as much as possible the skin protecting action, self-cleansing action, and other functions of the membranes of the human skin. The functions of conventional cosmetic compositions, however, have not been able to match the functions of the natural membranes of the skin.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide a cosmetic composition which further improves the skin protecting action, skin cleansing action, and other functions of conventional cosmetic compositions so as to give a coating of the skin close in function to the natural membranes of the skin.
In accordance with the present invention, there is provided a cosmetic composition comprising triglyceride oleate and yeast extract as components for proliferating the indigenous bacteria on the skin.
In accordance with the present invention, there is also provided a cosmetic composition further comprising as an ingredient for proliferating of the indigenous bacteria on the skin, in addition to the triglyceride oleate and yeast extract, an L-cysteine hydrochloride.
BEST MODE FOR CARRYING OUT THE INVENTION
In consideration of the fact that the skin protecting action, skin cleansing action, and other functions of conventional cosmetic compositions have not been sufficient if compared with the functions of the natural membranes of the skin, the present inventors took note of the fact that the natural membranes of the skin are the indigenous bacteria on the skin and their metabolites and, as a result, achieved the above-mentioned object by providing a cosmetic composition comprising components for proliferating the indigenous bacteria on the skin.
That is, the cosmetic composition according to the present invention includes triglyceride oleate and yeast extract, and further an L-cysteine hydrochloride, which are effective for proliferating Propinonibacterium acnes, Staphylococcus epidermidis, and other indigenous bacteria on the skin.
The ratios of addition of the above proliferating ingredients in the cosmetic composition (% by weight) depend on the compositions of the selective media for the skin indigenous bacteria (PUK medium; Kishishita, M., et al.: Appl. Environ. Microbiol., 40 1100-1105 (1980)) etc., but the preferable ranges are normally as follows: oleate; extract; and L-cysteine hydrochloride.
Further, these proliferating components are listed in the Japan Pharmacopoeia and the Standards of Cosmetic Ingredients, and therefore, the qualities, specifications, etc. are based on these standards. In particular, for the triglyceride oleate, olive oil containing 80 to 90% by weight thereof etc., may be used.
The cosmetic composition according to the present invention may contain therein any ingredients other than the above-mentioned components within a range not adversely affecting the effects of the present invention. For example, it is possible to suitably formulate with purified water, ethanol, oily substances, humectants, thickeners, antiseptics, emulsifying agents, medicinal ingredients, powders, fragrants, emulsion stabilizers, pH adjusters, etc.
More specifically, as the oily ingredients, liquid paraffin, vaseline, paraffin wax, squalane, beeswax, carnauba wax, olive oil, lanolin, higher alcohols, fatty acids, synthetic ester oils derived from higher alcohols and fatty acids, silicone oil, etc., can be exemplified.
As the humectants, sorbitol, xylitol, glycerol, maltose, propylene glycol, 1,3-butylene glycol, 1,4-butylene glycol, sodium pyrrolidone carboxylate, lactic acid, sodium lactate, polyoxypropylene fatty acid esters, polyethylene glycol, etc., can be exemplified.
As the thickeners, electrolytes such as carboxyvinyl polymers, carboxymethylcellulose, polyvinyl alcohol, carrageenan, gelatin, and other water soluble polymers and sodium chloride, potassium chloride can be exemplified.
As the antiseptics, methylparaben, ethylparaben
