Description

Detailed Description of the Invention [0001] [Industrial Application Field] The present invention provides a detergent composition, more specifically a detergent composition which has low irritation to the skin and which is good for the hair when used for washing the scalp and hair. This invention relates to a detergent composition that gives firmness, firmness, and a sense of volume. [Prior art and problems to be solved by the invention] Conventionally,
Synthetic anionic surfactants are widely used in detergent compositions such as shampoos and body shampoos. However, although these anionic surfactants have excellent cleaning power, they have the drawback of being highly irritating to the skin. On the other hand, nonionic surfactants are used in detergent compositions because they are hypoallergenic. However, because of its poor foaming power, it is not used in large amounts as the main ingredient in detergents such as shampoos where foam is important, and is used in combination with other surfactants, so it is non-ionic. There was a problem that the hypoallergenicity of the surfactant was impaired. [0004] Among nonionic surfactants, sugar-based nonionic surfactants such as alkyl polysaccharides are known to have low irritation and high foaming properties, so they are used in various cleaning agents. It was used in compositions. On the other hand, soft hair or damaged hair has the problem of being difficult to style because it lacks firmness, body, and volume. In order to overcome these drawbacks, shampoos containing chitosan derivatives, hydrolyzed proteins, etc. have been known, but none have yet been able to provide sufficiently satisfactory effects. [0006]Therefore, it has been desired to develop a cleansing composition that is not irritating to the skin and can impart firmness, body and volume to hair. [Means for Solving the Problems] Under these circumstances, the present inventors conducted intensive research and found that the above problems can be solved by using a combination of a sugar-based nonionic surfactant and a water-soluble chitin derivative.
