Description

In hair care, it is said that it is now a routine practice to “rinse” the hair with a treatment cosmetic containing a quaternary ammonium salt after washing the hair with shampoo. ing. By rinsing with a treatment cosmetic containing a quaternary ammonium salt (cationic surfactant), the quaternary ammonium salt is adsorbed on the damaged part of the hair, complementing the hair barrier function damaged by the damage. In addition, the action of the alkyl group facing the outside of the hair can reduce the coefficient of friction of the hair, and it can suppress the hair from being damaged or exacerbated by the scooping treatment. It is said. In addition, it is said that by containing silicone in such a treatment cosmetic, the coefficient of friction of hair can be further reduced and the optical effect of silicone can make hair look glossy. In such a treatment cosmetic, what is important is how to adsorb the necessary amount of the cationic surfactant to the hair. This is because the treatment cosmetics are used after being spread on the hair with a finger or washed away, or the treatment cosmetic is diluted with hot water, poured onto the hair, then washed with warm water, etc. This is because the treatment method involves a washing-off action, and in many cases, the necessary amount of the cationic surfactant cannot be retained on the hair. In other words, it can be said that development of a technique for retaining a necessary amount of a cationic surfactant on hair by a “rinsing” treatment has been desired.

On the other hand, octyldodecyl isostearate is known as an oily component having water retention, and blending into skin cosmetics is already known (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4). ). In addition, among silicones, aminopropyl silicone is also known in the art for incorporation into hair cosmetics (see, for example, Patent Document 5 and Patent Document 6). However, octyldodecyl isostearate and a cationic surfactant are used . The hair cosmetics to be contained are not known at all, and it is not known at all that such components have an effect of efficiently adsorbing the cationic surfactant to the hair.

In view of such a situation, the present inventors have made intensive research efforts to find a technique for retaining the necessary amount of a cationic surfactant in the hair by a “rinse” treatment, and as a result, octyldodecyl isostearate is obtained. It has been found that the retention of the cationic surfactant on the hair can be improved by incorporating the cation surfactant, and the present invention has been completed. That is, the present invention is as follows.
(1) A treatment cosmetic for hair, comprising 1) a cationic surfactant and 2) octyldodecyl isostearate.
(2) the cationic surfactant, characterized in that it is a A Le quilt trimethyl ammonium, treatment cosmetics for hair according to (1).
(3) the cationic surfactant, characterized in that it is a chloride alkyl trimethyl ammonium Niu beam, (1) or treating cosmetic for hair according to (2).
( 4 ) The hair treatment cosmetic according to any one of (1) to (3), further comprising an amino-modified silicone.
(5) The treatment cosmetic for hair according to (4), wherein the amino-modified silicone is aminopropyl dimethicone.

(3) Treatment cosmetic of the present invention The treatment cosmetic of the present invention contains the above-mentioned essential components and is for hair. In the treatment cosmetic of the present invention, in addition to the above-mentioned components, optional components usually used in cosmetics can be contained. The external preparation for skin of the present invention can contain, in addition to such components, optional components that are usually used in external preparations for skin.
