Description

  The present invention prevents hair from peeling off the cuticle, imparts wettability to the inside of the hair, enhances the moisture retention of the hair, and can provide a supple and moist finish without feeling sticky or heavy. The present invention relates to a hair conditioning composition.

Conventionally, in hair conditioning compositions such as hair rinses and hair treatments, cationic polymers such as cationized cellulose, various silicone bases, polyhydric alcohols are used to impart smoothness and wettability to hair and improve combing. In addition, humectants such as pyrrolidone carboxylates and amino acids are widely used (see, for example, Patent Documents 1 to 4).
However, when the above moisturizing agent is used, there is a drawback that sufficient water retention cannot be obtained and the feeling of sag is felt with time.
In addition, when a cationic polymer or various silicone bases are used, it accumulates on the hair when used for a long period of time, and often causes stickiness and stiffness.

Branched polyglycerol-modified silicone is known as a silicone base that has high affinity for hair and can give sufficient smoothness with a small amount of use without causing stickiness. It is also applied to hair cosmetics. (For example, refer to Patent Document 5).
However, simply blending the branched polyglycerol-modified silicone into the formulation has only limited adhesion to the hair surface, and the wettability cannot be imparted to the inside of the hair, so its effect is limited.
Japanese Patent No. 2554520 Japanese Patent No. 3127658 JP 2001-122737 A JP 2002-226330 A JP-A-2005-97152

  In the above circumstances, there has been a demand for a hair conditioning agent that can impart wettability to the inside of the hair and increase the moisture retention of the hair. That is, the object of the present invention is to prevent the hair from peeling off the cuticle, impart moisture to the inside of the hair, increase the moisture retention of the hair, and feel smooth and moist without feeling sticky or heavy. An object of the present invention is to provide a hair conditioning composition capable of giving a finished feeling.

  As a result of diligent research in view of the above circumstances, the present inventor has found that a combination of a branched polyglycerol-modified silicone and a peptide or protein obtained from any one of shellfish, fish, silk, and plants, or a derivative thereof, in a hair conditioning composition.
