Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair treatment composition containing an inorganic acid or organic acid neutralized product of amino-modified silicone oil.

[Conventional technology]

Currently, cationic surfactants and oils are added to hair cosmetics for the purpose of softening, lubricating, and antistatic effects, making hair soft, silky, and smooth. Quaternary ammonium salts are mainly used as cationic surfactants, and animal and vegetable oils, fatty acid esters, and the like are used as oils. Among oils, silicone oil is particularly preferred because it has excellent adsorption to hair and excellent lubricating effect.

[Problem that the invention seeks to solve]

Recently, however, various types of hair cosmetics have come on the market), and the demands on hair cosmetics have become more stringent than ever.

In particular, it is strongly desired to have an excellent feeling of use and high safety. However, cationic surfactants are irritating to hair and skin, and silicone oil alone has a weak hair treatment effect and is difficult to formulate into formulations such as emulsification and dissolution.

[Means for solving problems]

As a result of intensive efforts to develop an ideal hair treatment composition, the present inventors have developed an amino-modified silicone oil, which is obtained by neutralizing amino-modified silicone oil with an organic or inorganic acid, by introducing amino groups into silicone oil. The present invention was completed based on the discovery that the use of an acid-neutralized oil provides very excellent performance. The present inventor has developed a hair treatment agent that combines the characteristics of silicone, which has particularly excellent effects on hair among oils, and the effects of cationic surfactants, and is also safer than conventional cationic surfactants. As a result of detailed studies, the hair treatment composition of the present invention was discovered.

That is, the present invention provides an amine-modified silicone oil (average molecular weight 1500 to 4000) represented by the following general formula CD.
A hair treatment composition characterized by containing 0.1 to 10% by weight of an inorganic or organic acid neutralized product with an amino acid content of 0.5 to 3.0% by weight (as NH2) [However, , where m=1-30. n=10-500°X is an acid residue. ].

The acid neutralized product of the amino-modified silicone oil of the present invention is obtained by neutralizing the amino-modified silicone oil with a normal inorganic acid or an organic acid. Examples of the inorganic acid include hydrochloric acid, sulfuric acid, phosphoric acid, etc. , organic acids include acetic acid, succinic acid, lactic acid, malic acid, citric acid, L-glutamic acid,
Pyroglutamic acid etc. can be used. Na
: For acid-neutralized amino-modified silicone oil, even if you use a neutralized product that has been neutralized with an inorganic or organic acid in advance, the neutralized product may be generated in addition to the product during use. You can also do this. Further, the acid neutralized product may be neutralized with two or more types of acids.

The composition of the present invention can be used as a hair rinse or hair treatment.
□It is useful as a hair treatment agent such as ment, hair conditioner, hair cream, shampoo, and hair liquid.

〔Effect of the invention〕

Since the hair treatment composition of the present invention contains an inorganic acid or organic acid neutralized product of amino-modified silicone oil, it gives the hair the luster that is a feature of silicone oil,
It has a hair styling effect that improves the appearance of hair, and also has the characteristics of a quaternary ammonium salt. It also has the effect of softening the hair, preventing static electricity, and protecting the hair surface. In addition, conventional cationic surfactants are extremely irritating, but the hair treatment composition of the present invention causes almost no skin irritation and is extremely safe, making it an excellent hair treatment agent that has never been seen before. It is something.

Amino-modified silicone oil has conventionally been used alone as a raw material for cosmetics, but there is no example of it being neutralized with an acid and used as an amine salt as a cationic surfactant. When used as an amine salt, the effect on hair becomes very significant.
