Abstract: The present invention provides a composition for treating hair, skin, or fiber, comprising a cationic cellulose polymer. In the present invention, the cationic cellulose polymer may be used for various purposes by adjusting the molecular weight. Specifically, the present invention provides the use of the cationic cellulose polymer for imparting flexibility to hair, skin, or fiber, the use for cumulatively adsorbing active ingredients onto hair, skin, or fiber by allowing the active ingredients to be bound to the cationic cellulose polymer, the use for transferring active ingredients to hair, skin, or fiber by allowing the active ingredients to be bound to the cationic cellulose polymer, and the use of the cationic cellulose polymer, a crosslinking-mediating component having a carboxyl group or amine group, and a carbodiimide-based compound for preventing the loss of hair, skin, or fiber components.

Abstract: The present invention relates to a method for preparing monoglyceride sulfonate that is useful for a cleansing agent for a human body, economically in a large amount, from an inexpensive fatty acid using a convenient manufacturing unit. The present invention also provides a soft soap composition comprising monoglyceride sulfonate and a fatty acid soap, which has superior molding and stamping workability, softness, smoothness, foamability, and moisturizing ability. The present invention also provides a method for preparing a salt-containing soft soap using the fatty acid used for preparation of the monoglyceride sulfonate, which contains a lot of salt, so that is softens skin, easily removes waste materials, prevents irritation, promotes blood circulation, and prevents depilation and dandruff.
