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. Has come. The oily solid cosmetic obtained by this method has an opaque appearance, and a cosmetic having safety and excellent transparency has not been obtained yet.
In recent years, in lipsticks, lip balms, hair cosmetics, etc., the beauty of appearance (beauty in appearance) is emphasized,
Color developability (vividness of color), transparency (transparency), fresh finish effect, shiny finish effect (actual use effect), moist feeling, lasting moist feeling, non-greasy, Good elongation and stickiness (usability)
Those whose lips do not become rough, those whose lips do not dry (safety), have come to be demanded, visual characteristics, actual use effects,
Therefore, it has been desired to develop a transparent oil-based base material having excellent transparency, color development, portability, usability, and safety. This is clean,
It is a manifestation of the pursuit of pureness, lightness, freshness, naturalism and youth.

There are some problems in the prior art of transparent cosmetics, and there are 1) the following, which is poor in color developability, does not produce color, and lacks sharpness. 2) Transparency tends to disappear with temperature and aging. 3) It grows heavily and is difficult to attach, and it may bend or bend during use. 4) It lacks a fresh and glossy feeling of use and a glossy finish. 5) Durability (temperature resistance, bending strength) is lacking and shape retention is difficult. 6) Storage temperature Lack of stability over time (perspiration, oil bleeding, etc.). 7) Dyeing may cause dyeing and rough lips.
Therefore, it is desirable to develop excellent transparency, fresh luster, vivid color development, safety without dyeing, storage stability, and shape retention.

[0004]

Under such circumstances, the object of the present invention is to have excellent transparency, color developability, and aesthetic appearance, and to have elongation, stickiness, and feeling during use (no stickiness is good). , Gives a fresh bark and has excellent durability,
Dye does not stain the lips (safety and security), storage stability, good filling and molding properties, excellent transparency, color development,
An object of the present invention is to provide a transparent oily cosmetic excellent in shape retention, safety and stability. In particular, for transparent bases that are expected to produce clear and transparent colors, be sure to use dyes (oil-soluble dyes, water-soluble dyes) as colorants to prevent dyeing on the lips by these dyes (safety Properties), difficulty in shape retention (bending strength, bending) due to gel structure (transparent), usability (elongation, stickiness, durability), and stability over time are the most important issues.

[0005]

The above-mentioned problems are solved by the following components (1), (2), and (3) (1) hydroxystearic acid (particularly 12-hydroxystearic acid) and / or dextrin fatty acid ester (2). Polyether-modified silicone and / or long-chain alkyl-containing polyoxyalkylene-modified organopolysiloxane, (3) by containing an oily component that is liquid at room temperature, more preferably rosin acid polyhydric alcohol ester and / or rosin acid polyvalent It is achieved by containing an alcohol ester derivative and by blending an oil component whose oil component has a refractive index of 1.40 to 1.60.
