Description

  The present invention relates to a hair cosmetic.

  Hair damage has become serious due to coloring and perming agents, and the feeling of moistness is reduced and worries such as broken hairs and split ends are increasing. So far, for damaged hair, a cationic surfactant to give the rinsing feel of the treatment and a moist feeling of the finish, various silicones for repairing the damaged hair surface, and a lot of to give a moist feeling. A monohydric alcohol has been used (see, for example, Patent Document 1: International Publication No. 2004/058198 pamphlet). For the moist feeling that is particularly troublesome, the blending of polyethylene glycol as a polyhydric alcohol is useful. However, when blending polyethylene glycol at 50% by mass or more, there is a problem that the stability of the preparation is significantly reduced (for example, Patent Document 2: JP, 2001-181156, A). In addition, polyhydric alcohol is not effective for troubles such as broken hairs and split ends, and silicone derivatives such as amino-modified silicone (see, for example, Patent Document 3: JP-A-5-238920) and protein hydrolysis. Although things (for example, patent document 4: Unexamined-Japanese-Patent No. 2007-1953) etc. have been used, it was not enough.

(A) Silicone-modified clay mineral The silicone-modified clay mineral is a layer in which a silicone compound is supported between layers of a layered clay mineral, and can be used alone or in combination of two or more. The silicone-modified clay mineral can be prepared by previously mixing only an unmodified layered clay mineral and silicone. The mixing temperature and mixing time are not particularly limited, and it is good to mix at 5 to 80 ° C. for 1 to 3 hours. When the layered clay mineral and silicone are not mixed in advance, but separately mixed with the above components (B) and (C), the silicone floats upward as oil droplets, and the layered clay mineral swells in polyethylene glycol And cannot be formed in the form of a mineral to form a silicone-modified clay mineral.

The viscosity is a method measured in accordance with the quasi-drug raw material standard 2006 (Pharmaceutical Daily) General Test Method Viscosity Measurement Method 1 (p85). / 100 mL concentration of a silicone toluene solution is prepared, and the specific viscosity ηsp (25 ° C.) is obtained by the following formula (1). Next, the intrinsic viscosity [η] is obtained by substituting into the Huggins relational expression shown in the following formula (2). As the Huggins constant, the one described in Nakamuta, Nikka, 77 588 [1956] is used. Next, [η] is represented by the following formula (3). Substituting it into the Kololov equation, the molecular weight M is determined. Lastly, M is defined as A. shown in the following formula (4). J. et al. Substituting into the Barry equation, the viscosity η of the silicone compound is determined.
ηsp = (η / η0) −1 where η0 = toluene viscosity, η = solution viscosity (1)
.eta.sp = [η] + K '[η] ² K': Huggins constant (2)
[Η] = 0.215 × 10 ⁻⁴ M ^0.65 M: molecular weight (3)
