Among the cosmetic ingredients that are widely used for softness, softening effect, moisturizing, thickening, and bubble stabilizing effect in various hair and skin products. One. Generally, synthetic polymers cationicly polymerized using monomers such as cationic cellulose, cationic guar gum, vinylpyrrolidone, vinyl acetate, methacrylate, and vinylimidazolinium are used.

However, when these cationic polymers are used alone, hair or skin tenderness can be provided, but other characteristics such as smoothness and gloss cannot be provided, and the hygroscopicity of the polymer while the hair or skin is dried, etc. There is a problem that the feeling of use is degraded by showing a damp and sticky feeling.

To solve these problems, hair and skin products are being used with oily ingredients such as silicones, oils and waxes to protect hair and skin, prevent damage and impart conditioning effects. It is a trend. However, these oily components have the disadvantage of using additional stabilizing materials such as thickeners and surfactants in order to be able to be present stably in the composition.

It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention.

As described above, the conventional human cleansing composition is used by simply mixing a quaternary cationic polymer, silicone, and the like. However, the inventors of the present invention have found that the components used conventionally for the conditioning effect and the like are superior only to the specific effect and cannot exhibit the overall excellent effect, and a simple mixture of such components has problems in the stability of the composition.

It characterized in that it further comprises a self-emulsifiable silicone copolymer formed by copolymerizing.

As the nonionic water-soluble polymer monomer used to form the self-emulsifying silicone copolymer according to the present invention, a monomer of a nonionic water-soluble polymer including a vinyl group capable of addition polymerization is used. For example, N-vinyl-2-pyrrolidone, acrylic acid, methacrylic acid, maleic acid, acrylic and methacrylic amides, N, N-dimethyl acrylamide, hydroxy ethyl acrylate and methacrylate, hydroxy propyl acrylic One or more nonionic water soluble polymer monomers selected from the group consisting of latex and methacrylate can be used for the copolymerization.

The content of the nonionic water-soluble polymer monomer is preferably 1 to 90% by weight based on the total weight of the copolymer. When the nonionic water-soluble polymer monomer according to the present invention is in the above content range, it is possible to form a self-emulsifying silicone copolymer with a stable phase.
