Description

The present invention relates to a hair cosmetic, and more specifically, a leave-on type that is excellent in transparency, non-sticky, is familiar, further imparts a smooth feel and gloss to the hair, and is particularly excellent in sustaining a smooth feel. This relates to a non-aqueous hair cosmetic.

Hair is damaged by chemical or physical irritation such as hair color, bleach, permanent wave, ultraviolet rays, heat of dryer, etc., and gloss is lost, resulting in poor touch feeling due to dryness, split ends, cut hair, etc. Become. In these hairs, liquid oils typified by silicone oil are widely used for the purpose of imparting a feeling of touch and gloss. For example, by blending high molecular weight silicone and low boiling point silicone oil, smoothness and set of hair Non-aqueous aerosol for hair that imparts a glossy and smooth feel with an aerosol spray composition comprising a hair cosmetic composition having a holding power (see Patent Document 1), a high molecular weight dimethylpolysiloxane, a non-aqueous solvent and a propellant. A spray composition (see Patent Document 2) is disclosed. However, although the composition containing these polymer silicones is excellent in gloss and touch feeling, the hair becomes wrinkled or puffed over time, and the hair becomes hard due to the accumulation of polymer silicone. There was a drawback that the smooth feel persistence was insufficient. In addition, attempts have been made to add an oil or a moisturizing agent to prevent looseness, but the appearance of the composition is turbid, precipitates are generated, and the appearance is inferior. Therefore, it is strongly desired to have a hair cosmetic that is excellent in transparency, has appearance characteristics, does not feel sticky, is familiar, gives a smooth touch and gloss to the hair, and has a particularly smooth touch. It had been.
