Embodiment

[0055] Hereinafter, specific examples are given and the present invention will be described in more detail, but the present invention is not limited to the following examples. In addition, unless otherwise stated, the compounding quantity in a following example etc. shows mass %.

[0056] (Manufacturing example and comparative manufacturing example)

[0057] Polymerization was carried out according to the monomer composition shown in the following Table 1 to produce adhesive setting resins of the present invention (Production Examples 1 to 6), Comparative Production Example 1 not containing Monomer C, and Comparative Production Example not containing Monomer D 2.

[0058] Specifically, a mixture containing 100 parts of monomers was prepared in advance, and ethanol was added to a five-neck flask with a capacity of 1 L equipped with a dropping funnel, a reflux cooling gas, a thermometer, a nitrogen replacement tube, and a stirrer in which the mixture was charged. 100 parts, he...

Abstract

Disclosed is a hair cosmetic by which the hair (hair style) can be set due to the adhesiveness thereof and yet which shows an excellent hair-arranging ability (including hair-restyling ability). Specifically disclosed is a hair cosmetic comprising, as a hair-setting resin, a novel adhesive setting resin which is obtained by combining and polymerizing monomers having specific structures and shows an appropriate hardness and a high adhesiveness in a step of forming a film. In addition, this hair cosmetic preferably contains at least one component selected from a sugar, a sugar alcohol and an EO / PO derivative. Thus, a hair cosmetic having both a high hair-setting power and a good hair-arranging ability can be obtained.

Description

technical field [0001] The present invention relates to a hair cosmetic that can achieve both styling power and hair styling power (including hair restyling power). More specifically, it relates to a hair cosmetic that can fix and fix hair by containing a novel polymer, and is related to a hair cosmetic that can restyle the hair. Background technique [0002] Hair styling includes both functions of styling and maintaining styling. It is said that the principle of exerting these two functions is fixation and adhesion (Non-Patent Document 1). [0003] In hair styling by fixation, a film-forming agent (polymer resin) called a setting agent forms a solid film to shape the hair. For example, conventional hair gels, hairsprays, etc. are mainly based on hair styling mechanisms using styling resins. For example, Patent Document 1 describes hair cosmetics mainly using film-forming polymers such as polyvinylpyrrolidone, sodium polyacrylate, and polyvinylpyrrolidone-polyvinyl acetat...
