Description

  The present invention relates to a hair cosmetic, and more particularly to a hair cosmetic that provides a smooth, non-stiff, natural, soft and voluminous finish.

  In recent years, hair aesthetics have increased, and various hair and makeup such as hair color, perm, and hair iron set have been performed. As a result, hair damage due to multiple causes such as hair dyes and heat has become serious, and hair cosmetics such as conditioners and hair creams have been required to have higher care effects. For the realization, various oil formulations have been studied for hair cosmetics. Among them, highly polymerized silicone has a smooth and smooth coat film that lasts for a long time. Many are used for hair cosmetics (for example, refer patent documents 1-3). However, although highly polymerized silicone has a high care effect that smoothes the surface of the hair, it is sticky and has a heavy finish, making it a finish against the trend of natural and soft hairstyles. It was not satisfactory.

  On the other hand, for consumer needs such as giving hair firmness and firmness and increasing the volume, compounding of film-forming resins and various polymers has been studied (for example, see Patent Documents 4 to 6). Depending on the amount, the finished hair may be worried about the hardness and stiffness, or the hairs may stick together to produce an unnatural hair bundle.

  The present invention provides a hair cosmetic that achieves a natural, soft and voluminous finish while having a high care effect of smoothing the surface of the hair and being light and non-sticky to the eye. .

  Under such circumstances, the present inventor has conducted extensive research to solve the above problems, and as a result, has been surprisingly realized by combining a specific highly polymerized silicone with a cationic polymer, dimethyldiallylammonium chloride-acrylamide copolymer. In particular, while giving sufficient smoothness to the hair, it suppresses the disadvantages such as stickiness and wrinkle, and each hair does not feel unnatural as a smooth hair, and it feels soft and voluminous As a result, the present invention was completed.
