Problems solved by technology

However, clay minerals such as bentonite can stain the appearance of hair cleansing compositions, and their oil-absorbing properties can cause problems such as dry hair (Patent Document 3)
[0007] Therefore, although the detergent formulated with the above-mentioned polymer compound has anti-dandruff and cleansing effects, the hair becomes hard after use, cannot produce rich foam, and is difficult to comb through with a comb, and cannot ensure the stability of ZPT during long-term storage. sex

Embodiment 1～15 and comparative example 1～6

[0056] According to the following preparation methods, hair cleansing compositions of each composition of Examples 1 to 15 shown in Table 1 and Comparative Examples 1 to 6 shown in Table 2 were prepared, and evaluated for stability and usability. The results are shown in Table 1 and Table 2, respectively.

[0057] Preparation

[0058] Heat 40 wt% water to 75°C, add component (A), and stir uniformly to obtain solution A-1.

Abstract

The invention provides a hair detergent composition which allows zinc pyrithione to have an excellent stability at normal temperature and a high temperature and has a very excellent usability. The hair detergent composition of the invention comprises 5-20wt% of an anionic surfactant, 0.15-5wt% of an acrylate / vinyl neodecanoate copolymer or an acrylate / vinyl isodecylate copolymer, 0.01-0.15wt% of polyethylene glycol with the weight average molecular weight of 7000-45000, 0.5-2.0wt% of zinc pyrithione, and water.

Description

technical field [0001] The present invention relates to a hair cleansing composition. Background technique [0002] In hair cleansing compositions, zinc pyrithione (hereinafter also referred to as ZPT) is usually used to exert antidandruff, antipruritic and antibacterial effects. However, since ZPT is a water-insoluble powder and has a large specific gravity, it is difficult to disperse stably in the hair cleansing composition, and it tends to coagulate and precipitate. [0003] In order to solve the above-mentioned problems, it has been proposed to use nonionic polymer compounds, anionic polymer compounds, and amphoteric polymer compounds as stabilizers in hair cleansing compositions. [0004] As the nonionic polymer compound, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl hydroxyethyl cellulose, etc. are known to be used. (Patent Documents 1, 2). However, it is necessary to further mix hyd...
