Description

Cosmetics

The present invention relates to a cosmetic material.

Previously, in sebum, as the influence of unsaturated fatty acids represented by oleic acid and palmitoleic acid on the skin, it is known that there are slight inflammation, surface roughness, unevenness of pores, etc., and makeup removal. In order to improve the effects of such unsaturated fatty acids on the skin, various studies have been conducted in the industry. For example, Patent Document 1 describes that an unsaturated fatty acid adsorbent comprising an oleic acid ester-based surfactant coated with hexagonal plate-shaped zinc oxide can properly adsorb and immobilize unsaturated fatty acids contained in sebum, and can be used in formulating Prevents run-off when applied to makeup. Patent Document 2 describes a cosmetic containing polysiloxane microparticles having polysiloxane elastomer spherical microparticles and polyorganosilsesquioxane coated on the surface, which can suppress skin irritation caused by sebum. Changes in properties of cosmetics, changes in color, shine, etc. Patent Document 3 discloses that a composition for suppressing skin secretion containing a pseudophyllum extract can improve skin symptoms associated with excessive secretion of sebum.

On the other hand, hydroxypropyl cellulose has conventionally been used in pharmaceuticals, cosmetics, and the like as a water-soluble thickener. For example, Patent Document 4 describes the following alcohol-in-oil-in-water emulsion composition, which has less irritation and higher stability when used on the skin. The alcohol-in-oil-in-water emulsion composition has: (a) A gel-like alcohol phase containing hydroxypropyl cellulose; (b) a gel-like oil phase containing palmitate dextrin; and (c) polyethylene with a saponification degree of 70-98 mol%. Alcohol and carboxyvinyl polymer, and it is a gel-like aqueous phase. [Prior Art Literature] [Patent Document]

In the known technology, as described in Patent Document 1 and Patent Document 2, when sebum is adsorbed in the form of powder, there is a partial makeup retention effect produced by the sebum capture ability on the skin surface where the powder exists, but it cannot Obtain the improvement effect of the skin itself. Also, in the case of using a plant extract as described in Patent Document 3, although sebum secretion is suppressed, the effect on the skin cannot be improved by capturing unsaturated fatty acids.

The inventors of the present invention have found that by using hydroxypropyl cellulose with a high degree of substitution to specifically capture unsaturated fatty acids represented by oleic acid as a sebum component from the outside, the condition of the skin can be improved, and further use liquid glycol in combination And specific water-soluble polymers can obtain cosmetics with high effect of inhibiting skin roughness caused by sebum.

[Examples 15-16] An oil-in-water emulsified cosmetic (makeup base) having a composition shown in Table 3 was produced in the same manner as in Examples 1 to 10 except that the powder was added last. The obtained cosmetics can improve skin conditions such as the brightness of plain skin, the flushing of cheeks of plain skin, the smoothness of plain skin, etc., and when applying foundation, etc., they have good compliance and will not cause unevenness. Evens out makeup and keeps it in place.
