FIELD OF THE INVENTION The present invention comprises hydroxystearic acid (particularly 12-hydroxystearic acid) and polyether modified silicone and / or long chain alkyl-containing polyoxyalkylene modified organopolysiloxane,
Prevents dyeing on the lips, coloring, persistence of finish,
The present invention relates to a transparent base material having excellent transparency, usability, shape retention and stability, and a cosmetic composition containing the same. The use of the transparent base of the present invention is not limited to cosmetics such as lip balms, lip gloss, lip color gloss hair tics, fragrance sticks, etc. Pharmaceutical bases such as agents and anti-itch agents. It is widely used as a base material for stationery such as crayons.

2. Description of the Related Art Conventionally, in the field of cosmetics, oily solid cosmetics have been prepared by heating and melting waxes such as polywax, ceresin, candelilla wax, beeswax, and carnauba wax into cosmetic oils, and filling and molding into desired shapes. I came. The oily solid cosmetics obtained by this method have an opaque appearance, and no safe and highly transparent cosmetics have been obtained yet.
In recent years, in lipstick lip balm, an oily base excellent in transparency has been sought for the purpose of emphasizing the beauty of the appearance to give a transparent finish when applied to the lips. Clean, pure, light, fresh,
It is a manifestation of the pursuit of naturalness and youth, and in lipsticks, hair tics, fragrance sticks, etc., it is desired to develop a base material that is safe, transparent, and easy to use in order to produce a clear color tone. It was rare. As a highly transparent base, various methods using hydroxystearic acid (particularly 12-droxystearic acid) have been proposed, but it prevents the dye from sticking to the lips, is safe, has a color-forming property, and is used. So far, no transparent base material has been developed that has excellent feeling and durability of finish.

DISCLOSURE OF THE INVENTION The present invention prevents dyeing on the lips with a dye, safety without drying the lips, durability of finish, transparency, color developability, feeling of use, shape retention, We proceeded with the research aiming at obtaining a transparent base material with excellent stability. In particular, the transparent base, which is expected to produce a clear and transparent color, is effective for preventing irritation to the lips due to dyeing on the lips and satisfying makeup retention and usability at the same time. It was the biggest challenge.

By preparing a composition comprising hydroxystearic acid (particularly 12-hydroxystearic acid) and a polyether modified silicone and / or a long chain alkyl-containing polyoxyalkylene modified organopolysiloxane, To obtain a transparent base material that prevents dyeing due to the dye, does not irritate the lips, and has excellent safety, durability of finish, transparency, color development, feeling of use, shape retention and stability. The following is a description of the configuration of the present invention, which was successful in completing the present invention. The hydroxystearic acid used in the present invention is mainly hydrogenated to ricinoleic acid, which is a saturated fatty acid having a hydroxyl group improper to the 12th carbon, 12-hydroxystearic acid (melting point, 76.6 to 76.9 ° C). It is a transparent base solidifying agent, and the gel has a thin film and has little stickiness (stickiness) and wax feeling (weight of elongation), extensibility,
It has excellent adhesion and little change in hardness over a wide temperature range. In addition, hydroxystearic acid used in the present invention includes 2-hydroxystearic acid, 3-hydroxystearic acid, 4-hydroxystearic acid and 5-hydroxystearic acid.

3-hydroxystearic acid, 14-hydroxystearic acid, 15-hydroxystearic acid, 16-hydroxystearic acid, 17-hydroxystearic acid, 1
The amount of hydroxystearic acid, such as 8-hydroxystearic acid, used varies depending on the formulation of the target product, transparency, shape retention, usability, functionality, etc., but usually 1.0% in a transparent base. It is preferably about 45.0% by weight, more preferably 2.0-15.0% by weight. In addition, in the present invention, a hydroxycarboxylic acid having an alkyl group having 9 to 34 carbon atoms is preferably used, and among them, a hydroxycarboxylic acid having an alkyl group having 14 to 20 carbon atoms is preferable. The polyether-modified silicone and long-chain alkyl-containing polyoxyalkylene-modified organopolysiloxane used in the present invention are as follows. Uses 1.0-99.0% by weight. The main polyether-modified silicones are polyoxyethylene / methylpolysiloxane copolymers (Shin-Etsu Silicone KF601
