PURPOSE:To obtain a make-up cosmetic having excellent durability of make-up, light spreading, refreshing and characteristic feeling in use by blending a cosmetic with a specific silicone compound. CONSTITUTION:A make-up cosmetic is blended with usually 0.5-95wt.%, preferably >=5wt.% silicone compound having a structure shown by formula I (R is 16-30C alkyl or phenyl and repeating units may be different; n is 3-7 integer) and preferably >=40 deg.C melting point as an essential component to give a make-up cosmetic having the above-mentioned effects. The compound shown by the formula II is obtained by reacting a compound shown by formula II with an olefin by a general method such as hydrosilylating reaction, etc.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized by containing solid silicone wax, and provides makeup that has excellent long-lasting properties, is light in application, and has a distinct and unique feeling of use. It provides a fee.

[Prior Art] Conventional makeup cosmetics consist of extender pigments such as talc and mica, coloring pigments such as iron oxide, oils, activators, fragrances, antioxidants, antiseptic agents, etc. Various properties have been required for their function as materials. In particular, regarding the longevity of makeup, many studies have been conducted on it as the most important function. There are methods to make makeup last longer using emulsified bases, but no perfect solution has been achieved as issues such as sebum, sweat, and physical friction affect makeup longevity in a complex manner. Furthermore, since waxes used in cosmetics have drawbacks such as being greasy and spreadable, it has been desired to improve the feel upon use.

[Problem M to be solved by the invention] In view of the above-mentioned circumstances, the present inventors have conducted extensive research in order to obtain a makeup cosmetic that has excellent makeup durability, spreads well, and has a unique feeling of use. As a result, it was discovered that this problem could be solved by blending a specific silicone compound, and the present invention was completed.

[Means for Solving the Problems] That is, the present invention is a makeup cosmetic characterized by blending one or more silicone compounds having the structure of the following general formula (A).

[R in formula (A) represents an alkyl group having 16 to 30 carbon atoms or a phenyl group, and the repeating units may be different. n is an integer from 3 to 7. The configuration of the present invention will be explained in detail below.

The silicone compound used in the present invention has the general formula (
In the formula A), R can be an alkyl group having 16 to 30 carbon atoms or a phenyl group, and n can be any integer of 3 to 7. It is desirable that the melting point is 40° C. or higher.

The silicone compound used in the present invention has the following general formula (B
) is known to be obtained by reacting an olefin with a compound having a 5f-H bond.

[In formula (B), n is an integer of 3 to 7. ] In this case, if an olefin with a single chain length was used, there was no distribution in the carbon chain length of the alkyl group (A), but if a mixture of olefins was used, the carbon chain length of the alkyl group in the repeating unit varied ( A) is obtained.

The silicone compound used in the present invention can be produced by a general method such as a hydrosilylation reaction. To illustrate a specific hydrosilylation reaction, an olefin and the compound represented by (B) above are mixed in equivalent amounts, a catalytic amount of chloroplatinic acid is added thereto, and the mixture is refluxed in toluene.

After several hours, an appropriate amount of activated carbon is added, filtered, and the solvent is removed.

The amount of the silicone compound used in the present invention varies depending on the form of the cosmetic and can usually be blended in the range of 0.5 to 95%, but in order to improve the makeup's longevity,
% or more is preferable.
