Description

Hair cosmetics

The invention relates to a hair cosmetic. More specifically, the present invention relates to an ointment-like hair cosmetic prepared by combining two or more nonionic surfactants having different HLB (Hydrophile Lipophile Balance) values in a specific range.

Among the cosmetics for hair finishing, especially as hair styling agents (hair styling agents) that value hair styling, there are known ointment-like hair styling agents (called hair grease or pomade) ), excellent operability and gloss to the hair. The ointment-like hair styling agent exhibits a solid shape or a cream shape that is less fluid than the gel-like hair styling agent, and is usually filled into a can-type container, etc., and used in an appropriate amount with fingers.

There are oil-based hair styling agents that use liquid oils and solid oils, and water-based types in which polyols or film-forming polymers and tackifiers are blended into water. The previous oil-based cream-type hair styling agent used liquid oil to hold down the hair. Although the gloss was excellent, it sometimes caused the frontal hair to sag due to the movement of the head after hair styling.

In Patent Document 1, it is pointed out that there is a problem of unique stickiness of oil in an oil-based ointment hair conditioner. It is believed that by combining two specific types in an oil-free water-based ointment hair conditioner The structured polyoxyethylene alkyl ether is formulated to improve the suppression of stickiness, ease of application, hair straightening power and stability.

As a cosmetic containing oil, Patent Document 2 discloses a gel-like cosmetic containing a nonionic surfactant, a liquid higher alcohol, a liquid oil, and water. It is believed that the gel-like cosmetic has moderate viscosity and good stability over time, and is relatively gentle on the skin or hair as a hair styling agent or cleaning agent.

However, the two polyoxyethylene alkyl ethers in Patent Document 1 and the nonionic surfactants described in Patent Document 2 are hydrophilic surfactants with an HLB of 10 or more, which suppresses or improves the feeling of stickiness. Insufficient in terms of sex. [Prior Technical Literature] [Patent Literature]
