[0101] The two-layer separation-type hair cosmetics shown in Table 1 were prepared, and the following methods and criteria were followed for "separation speed of the two layers", "turbidity of the lower layer", "stability over time" and "performance as a hair cosmetic" Make an evaluation.

[0102] "Separation speed of two layers"

[0103] A cylindrical colorless transparent PET container with an inner diameter of about 3 cm and a height of about 12 cm was filled with a uniformly mixed 25° C. double-layer separation type hair cosmetic so that the height from the bottom surface was 10 cm. After filling the liquid, the PET container was placed under an atmosphere of 25° C., and the interface between the upper layer and the lower layer after a certain period of time had elapsed was visually observed.

[0104] ○: After 24 hours, the interface can be observed at a position more than 4 cm from the bottom surface

[0105] △: After 24 hours, the interface can be observed at a positio...

Abstract

Disclosed is a non-aerosol separated two-layer hair cosmetic, which contains components (A) and (B) at a ratio of (A) / (B)=0.2 to 10 by mass, and comprising an oil-in-water emulsion layer and an aqueous layer. (A): a silicone with a number average degree of polymerization of 300 to 20,000 having a number average particle diameter of 0.05 to 20 [mu]m, chosen from a group consisting of dimethicone, dimethiconol, and amino-modified silicone; 0.1-6 mass % (B): a water-soluble cationic polymer with a weight-average molecular weight of 50,000-1,000,000, chosen from a group consisting of polyquaternium-6, polyquaternium-7, polyquaternium-16, and polyquaternium-22.

Description

technical field [0001] The present invention relates to a two-layer separation type hair cosmetic. Background technique [0002] Conventionally, for the purpose of protecting hair, improving touch, etc., there are known hair cosmetics containing oil-based components as hair water (Hair water). Hair cosmetics of this form have been proposed many times because they are excellent in that the hair is moist and tidy without stickiness, and can be finished easily and naturally. However, if a large amount of oil-based components is contained in order to further improve performance, it will become an emulsion-type dosage form using a large amount of emulsifier, which will cause deterioration of touch compared with hair conditioner, and also cause problems such as difficulty in ensuring storage stability. Therefore, There is naturally a limit to the amount of oily ingredients that can be blended. [0003] As a product that simultaneously solves such issues of hair conditioner and e...
