Abstract

The objective of the present invention is to provide: a copolymer having a wide degree of freedom of formulation as a spray, mist, wax, and the like, while having high setting properties and hair styling performance; and a cosmetic material composition containing the copolymer. The present invention relates to: a copolymer that has an endothermic start point between -25 DEG C and 40 DEG C, does not dissolve in water under 30 DEG C, and contains a constituent unit corresponding to the vinyl monomer (A) represented by general formula (1), and a constituent unit corresponding to the vinyl monomer (B) represented by general formula (2). (In general formula (1), R1 represents a hydrogen atom or a methyl group, R2 represents an alkylene group having 2-4 carbon atoms, R3 represents a hydrogen atom or an alkyl group having 1-3 carbon atoms, and m represents an integer from 15 to 50. In general formula (2), R4 represents an hydrogen atom or a methyl group, R5 represents an alkyl group having 2-10 carbon atoms, p and q each represent the integer 0 or 1, and p+q=1.)

Description

technical field

[0001] The present invention relates to a copolymer having a specific structure, and a cosmetic composition containing the copolymer. Background technique

[0002] In recent years, waxy hair styling products (pomade) have been widely accepted mainly by young people. Mousses, gels, and spray hairsprays, which are traditional hair fixatives, show the setting properties by forming a film on the hair with resin, while pomades, on the other hand, use carnauba wax, candelilla wax, The microcrystalline wax is used as the center of the solid oil to achieve the hair styling effect of regulating and managing the hair (for example, patent documents 1 and 2).

[0003] Pomades have been developed so far in pursuit of higher hair styling properties (setting power, holding properties, and re-styling properties) and a good feeling of use. For example, hair styling products (patent document 3) coordinating polyethylene glycol with a high degree of polymerization, wax, and n...
