Description

[Detailed description of the invention] Industrial applications The present invention is a hair rinse and a hair treatment.

Regarding hair cosmetics such as hair lotions and hair conditioners, to be more specific, hair cosmetics that can be effectively used for drying hair after washing and can give a moisturized and smooth feeling without stickiness to the hair after drying. Regarding cosmetics.

In recent years, heat tools such as hand dryers and curl dryers have been increasingly used to dry and care for hair after washing. However, these heating devices tend to damage the hair, and especially at the tips of the hair, where damage is easily noticed, the moist feeling is lost and the hair becomes less manageable. Furthermore, such disadvantage A is particularly noticeable when hair is subjected to chemical treatments such as cold waving or hair dyeing.

Conventionally, as hair cosmetics to eliminate the above-mentioned disadvantages, hair cosmetics such as stearyldimethylammonium chloride and cetyltrimethylammonium chloride have been used.
Hair cosmetics have been proposed in which a grade ammonium salt and a higher alcohol such as cetyl alcohol, stearyl alcohol, or behenyl alcohol are used in combination as active ingredients for preventing hair damage and imparting a moist feel to the hair.

However, hair cosmetics containing these quaternary ammonium salts and higher alcohols as active ingredients have not been able to achieve satisfactory effects because they are not sufficiently adsorbed onto the hair.

Therefore, in order to improve the adsorption of these active ingredients, animal and vegetable oils, hydrocarbon oils, ester oils, protein decomposition products, and the like are generally used in combination with the quaternary ammonium salt and higher alcohol. However, these oils and protein decomposition products must be blended in large amounts in order to obtain the desired effect, and in the case of products that require rinsing, there is a problem in their persistence in the hair. In addition, due to their nature, these oils and protein decomposition products can give the hair a moist feel after drying and make it easier to manage, but on the other hand, they can leave the hair with a sticky and heavy finish after drying. There is a problem.

For this reason, there has been a strong demand for hair cosmetics that can prevent hair damage after drying and give hair a moist feel and smoothness without being sticky.

In order to achieve the above object, the inventors of the present invention have made intensive studies and have added the following (
1) 0.1 to 10% by weight of the cationic surfactant and/or mono-N-long chain acyl basic amino acid lower alkyl ester salt of the formula, 0.1 to 10% of the total weight of liquid oil, and heme. Iron compounds, especially hematin, account for 0.01 of the total
When containing ~5% by weight, damage to the hair can be well prevented when hair is dried and groomed using a heat tool, etc. after washing, and this gives the hair a moist feel without stickiness after drying. Furthermore, because the active ingredients have a high adsorption and persistence on the hair, the above effects do not decrease with rinsing, and sufficient effects can be obtained even with a small amount. Based on these findings, the present invention has been completed.

The present invention will be explained in more detail below.

As described above, the hair cosmetic of the present invention contains a cationic surfactant of the following formula (1) and/or a mono-N-long chain acyl basic amino acid lower ester, a liquid oil component, and a heme iron compound. .
