Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair deforming composition, and more particularly to a hair deforming composition which is excellent in high humidity resistance and gives a long-lasting hair deformation without damaging curly hair.

[0002]

2. Description of the Related Art Permanent wave (hereinafter referred to as "perm") is widely used as a method for straightening straight hair by straightening curly hair. A perm means that a composition containing a reducing agent such as thioglycolic acid or cysteine is first applied to hair to cleave the S—S bond of the hairy keratin protein under alkaline conditions, and then, such as sodium bromate. The hair is semi-permanently deformed by applying an oxidizing agent and then re-bonding.

On the other hand, as a method for temporarily straightening curly hair, a method using a commercially available curly hair curative agent, a blowing method by a hairdresser, and the like are performed. The former uses a mild reducing agent, an oxidizing agent, etc., and the latter temporarily breaks hydrogen bonds in the hair and then blows them to forcibly form other hydrogen bonds.

[0004]

However, the hair setting mechanism in the perm is the cleavage-recombination of the SS bond of the keratin protein in the hair, and when the hair is subjected to such a chemical treatment, Keratin protein in hair becomes weakened. The weakened hair is easily affected by physical external force such as brushing, which causes hair damage. On the other hand, the method using commercially available curly hair care agents does not provide sufficient effect because it uses a mild reducing agent and oxidizing agent, and the blowing method requires advanced techniques at home. It cannot be done easily, and the set easily collapses under high humidity.

Therefore, there has been a demand for the development of a hair deforming composition which can stably maintain the deformation without damaging the hair.

[0006]

Means for Solving the Problems As a result of intensive investigations in view of such circumstances, the present inventors have found that a composition containing a specific organic acid and a penetration enhancer and exhibiting acidity damages hair. However, the present invention has been completed, and the present invention has been completed.

That is, the present invention provides the following components (a) and (b); (a) one or more selected from DL-pyroglutamic acid, hydroxycarboxylic acid, dicarboxylic acid and salts thereof, (b) ) Benzyl alcohol, benzyloxyethanol and the following general formula (1)
