Description

The present invention relates to cosmetics such as oily solid cosmetics, beard cosmetics, hair cosmetics and the like, and more specifically, by containing an adsorbed and purified natural high melting point wax, it is excellent in moldability and retention. The present invention provides a cosmetic that has good mold releasability from a mold or a container, and is excellent in adhesion, color developability, and usability.

Conventionally, there are various cosmetics containing natural high melting point wax. Cosmetics containing candelilla wax, which is a typical natural high melting point wax, have gloss, pigment dispersibility, adhesion or carbonization in candelilla wax derived from the resin and ester content in candelilla wax. There are many precedents for oily solid cosmetics utilizing the moldability of hydrogen and ester. In addition, there are many known examples of eyelash cosmetics and hair cosmetics using the adhesive strength derived from the resin of candelilla wax. In addition to the decolorized and refined candelilla wax, the candelilla wax includes a candelilla wax from which a resin component has been removed, a candelilla wax that has been refined to contain 65% by weight or more of hydrocarbons, and the like.

Natural high melting point waxes include carnauba wax, rice wax, cane wax, and wood wax in addition to candelilla wax. Carnauba wax and rice wax are also used in oily solid cosmetics, salmon cosmetics, and hair cosmetics by utilizing the gloss derived from the ester content and resin content, pigment dispersibility, adhesion, and moldability by the ester content. There are many precedents.

However, the conventional candelilla wax has a hue of brown to yellow, and when it is blended in a large amount, the cosmetic is colored or has a peculiar odor. Therefore, there is a problem that it is difficult to reduce the fragrance or reduce the fragrance. In addition, there is a drawback in that the problem of changing odor over time occurs. Further, in the case of the purified candelilla wax from which the resin component has been removed, there is a problem that the adhesion of the cosmetic to the skin and hair, gloss, and pigment dispersibility are impaired. In addition, in the case of candelilla hydrocarbon wax refined to contain 65% by weight or more of hydrocarbons, the ester content and resin content are clearly less than the original candelilla wax. Adhesion, gloss, and pigment dispersibility products are not sufficient, and the formability, individualization, and shape retention of liquid oil are extremely poor, so it can be used in combination with other hydrocarbon waxes and ester waxes. It was difficult to use.

Conventional carnauba wax and rice wax also have a brown to yellow hue, and when blended in a large amount, the cosmetics are colored or have a characteristic odor, which makes it difficult to make no fragrance or low fragrance.

As a result of diligent research, the inventors of the present invention have made it possible to rapidly reduce the pigment component and smell without impairing the characteristics of the natural high melting point wax by reducing the recovery rate to 79.0% or less when the natural high melting point wax is adsorbed and purified. It has been found that impurities such as components, peroxides, and carbonyl compounds can be effectively removed, and that the above problems can be solved, and the present invention has been completed.

That is, in the present invention, after recovering in a solvent, the solution is passed through an adsorption tower filled with an adsorbent, the impurities are adsorbed and removed, and the recovery of the natural high melting point wax obtained by distilling off the solvent is 79.0. %, And containing 0.1 to 20% of this purified natural brain melting point wax. Examples of the solvent used for purification include n-pentane, n-hexane, n-heptane, n-octane, ethanol, isopropanol and the like, and examples of the adsorbent include silica gel, magnesium silicate, activated clay, zeolite, activated carbon. The

That is, the present invention provides the cosmetic according to claim 2, wherein the natural high melting point wax is candelilla wax, carnauba wax, or rice wax.

As described in detail above, the cosmetic of the present invention can be light-colored and fragrance-free, has excellent moldability and retention, has good releasability from a mold and a container, adherence, color developability, And the outstanding effect that it has the outstanding usability is produced.
