Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention contains a hair cosmetic composition, and more specifically, contains a cationic polymer and a nonionic polymer, and is capable of firmly fixing hair and is not wet. The present invention relates to a hair cosmetic that can maintain its appearance and gloss for a long time.

[Conventional technology]

Hair cosmetics generally give a pleasant feel without stickiness during hair treatment, give softness to wet hair, and can easily fix a wave, and after drying, it is easy to give a style. It is desired to provide hair that is fluffy, non-chargeable, elastic and soft to the touch, non-greasy, and shiny after hair styling.

Conventionally, an anionic polymer, a cationic polymer, and an amphoteric polymer have been blended in hair cosmetics for this purpose (French Patent No. 2383660, JP-A-56-92812).
issue). In particular, the cationic polymer is particularly preferably used because it has excellent penetrability between hairs, is well fixed to the hair to give flexibility, and provides a moisturizing and supple hair styling effect.

[Problems to be solved by the invention]

However, a cationic polymer having these various properties cannot sufficiently impart gloss to hair, and since the coating film is sometimes too soft, a set effect of appropriate strength cannot be obtained,
Further, there is a drawback that the skin becomes sticky and the rinsing property is poor at the time of washing hair, and improvement has been desired.

[Means for solving problems]

Under such circumstances, the present inventors have conducted earnest research to improve the drawbacks of such a cationic polymer, and as a result, used a cationic polymer and a nonionic polymer in a specific ratio and further used mica titanium in combination. Hair cosmetics improve the above-mentioned drawbacks, form a film with appropriate hardness on the hair to give a strong set effect, make it easy to wash hair, and fix the hair bundle in a certain direction.
