DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition based on an anionic surfactant and / or an amphoteric surfactant, which gives an excellent foam feel when used.

[0002]

2. Description of the Related Art Detergent compositions for washing the body and the like need not only have a detergency but also have a smooth foam feel when used. As substances conventionally used for this purpose, lanolin and its derivatives, lecithin and its derivatives, higher alcohols, fatty acids and other fatty agents have been proposed, all of which have sufficient effects. However, there are problems such as no foaming and adverse effects such as foaming and a decrease in detergency, and satisfactory products have not yet been obtained.

[0003]

SUMMARY OF THE INVENTION The present inventors have conducted intensive studies to obtain a detergent composition having an improved foam feeling without impairing foaming. As a result, the present inventors have found that anionic surfactants and / or amphoteric surfactants have been obtained. The present inventors have found that the above object can be achieved by blending a specific chitosan derivative in a detergent composition based on an agent, and have completed the present invention. Accordingly, an object of the present invention is to provide a detergent composition based on an anionic surfactant and / or an amphoteric surfactant which has a sufficient detergency and an excellent foam feel during use. .

[0004]

That is, the present invention relates to a detergent composition based on an anionic surfactant and / or an amphoteric surfactant.
The present invention relates to a detergent composition containing-(3-carboxypropanoyl) -6-O- (carboxymethyl) chitosan (hereinafter, abbreviated as "CPCM chitosan") as an essential component.

(Test method) Foam feel test A panel of 10 to 20-year-olds was asked to wash 5 ml of a sample in the case of a liquid detergent by hand and forearm three times with warm water of about 40 ° C. In the case of a solid detergent, The detergent was rubbed with warm water of about 40 ° C. five times with both hands, and the average of the values evaluated according to the following criteria was determined. The foam is smooth.・ ・ ・ ・ 4 points Foam is slightly smooth ・ ・ ・ ・ 3 points Foam is not so smooth ・ ・ ・ 2 points Foam is not smooth ・ ・ ・ ・ ・ ・ 1 point

Examples 1 to 4 and Comparative Examples 1 and 2 Liquid detergents having the compositions shown in Table 1 were prepared, and the smoothness of the foams of the obtained liquid detergents was evaluated. The results are shown in Table 1.

[0014]

[Table 1]

As is clear from the results shown in Table 1, all the detergents containing CPCM chitosan of the present invention had good foam feeling and did not decrease the detergency. Further, the cleaning agents of Comparative Examples 1 and 2 which did not contain the CPCM chitosan or had a low blending amount were inferior in foam smoothness. Further, the detergent containing lanolin alcohol as a superfatting agent had a slightly inferior foam smoothness, and the detergency was slightly reduced.
