Description

{NON-AQUEOUS HAIR TREATMENT AGENT}

The present invention relates to a non-aqueous hair cosmetic composition capable of suppressing discoloration of hair subjected to dyeing treatment with a hair dye.

Recently, hair dyeing using a hair dye has become popular. In addition, the necessity of suppressing discoloration of the hair after the dyeing treatment is also increased. Ultraviolet rays contained in sunlight can be considered as a cause of discoloration of hair after dyeing treatment.

In Patent Documents 1 to 4, it is not intended to be applied to hair. However, in order to suppress damage to the skin caused by ultraviolet rays and deterioration of the quality of the cosmetic itself, various kinds of ultraviolet absorbers are blended, A water-based cosmetic containing water is proposed.

[Patent Document 1] Japanese Unexamined Patent Application Publication No. 2006-117669 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2006-117670 [Patent Document 3] JP-A-2009-91260 [Patent Document 4] JP-A-2009-256215

However, even if the cosmetics described in Patent Documents 1 to 4 are applied to the hair subjected to the dyeing treatment, the discoloration thereof can not be satisfactorily suppressed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a non-aqueous hair cosmetic composition capable of suppressing discoloration of hair subjected to dyeing treatment with a hair dye.

The non-aqueous hair cosmetic composition according to the present invention, which has been able to achieve the above object, is characterized by comprising diethylhexylene glyidene malonate or a derivative thereof, or asia palm fruit oil.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a non-aqueous hair cosmetic composition capable of suppressing discoloration of hair subjected to dyeing treatment with a hair dye.

The mechanism of fading by ultraviolet rays of the hair subjected to the dyeing treatment is thought to be that active oxygen is generated by ultraviolet irradiation and this decomposes the pigment in the hair. Here, when the hair absorbs moisture such as moisture and sweat in the air and swells, active oxygen tends to move, and the action of the hair tends to increase, and it has been found that fading is more likely to proceed.

Thus, in the present invention, by applying a non-aqueous hair cosmetic composition, moisture such as moisture and sweat in the air is hard to enter into the hair. In addition to this, swelling of the hair caused by moisture derived from the hair cosmetic composition can be prevented, and the action of active oxygen generated by ultraviolet rays is suppressed. In addition, by using a component capable of exhibiting a good antioxidative ability even when blended with a non-aqueous hair cosmetic, fading of hair subjected to the dyeing treatment can be satisfactorily suppressed.

The non-aqueous hair cosmetic composition of the present invention is mixed with diethylhexylene glycidyl malonate or a derivative thereof (for example, bishexyl hydroxydimethoxybenzyl malonate), or asia palm fruit oil. These components have a function of suppressing discoloration of hair caused by active oxygen, and even when the hair cosmetic is made of a non-aqueous system, their functions are excellently exerted.

In the non-aqueous hair cosmetic composition, only one of the diethylhexylene glyidide malonate and derivatives thereof and the ascorbic acid fruit oil may be blended, or two or more blended blends may be blended.

(In the case of mixing a plurality of such non-aqueous hair cosmetic materials, the total amount thereof is the same hereinafter) in the non-aqueous hair cosmetic composition, diethylhexylene glydide malonate or a derivative thereof, Is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, and particularly preferably 0.2% by mass or more from the viewpoint of better ensuring the effect of its use. However, if the amount of diethylhexylene glyidene malonate or a derivative thereof or the amount of the non-aqueous hair cosmetic oil in the non-aqueous hair cosmetic oil is excessively large, the effect of preventing discoloration is improved, but the hair is not sticky, It is damaged. Therefore, the blending amount in the non-aqueous hair cosmetic composition is preferably not more than 1% by mass, more preferably not more than 0.8% by mass, more preferably not more than 0.5% by mass in the non-aqueous hair cosmetic composition, diethylhexylene glydide malonate or a derivative thereof, Or less, and particularly preferably 0.4 mass% or less.

In the non-aqueous hair cosmetic composition of the present invention, it is preferable that ethylhexyl methoxycinnamate and hexyl hydroxybenzoylbenzoate be further blended.

Ethylhexyl methoxycinnamate has a property of absorbing ultraviolet B wave. Diethylamide Hydroxybenzoyl Hexyl benzoate has the property of absorbing ultraviolet A wave. Therefore, when the non-aqueous hair cosmetic composition of the present invention contains both ethylhexyl methoxycinnamate and hexyl hydroxyethylbenzoylbenzoylbenzoate, the function of suppressing discoloration of the hair subjected to the dyeing treatment by ultraviolet .
