SUMMARY OF THE INVENTION

When people use shower gel to wash their bodies, in order to clean them, they usually use tools or make rich foam with their bare hands. However, when children are left to wash their bodies independently, it is found that children cannot lather well on their bodies. For example, children often use an insufficient amount of body wash, so that the foam cannot be washed all over the body, so the whole body cannot be washed; If the time for a certain part is too long, the foam attached to the rest part disappears, which cannot achieve the effect of cleaning. In Patent Documents 1 and 2, there is no description at all about improving the foamability of the cleaning composition.

The object of the present invention is to provide a detergent composition which can generate rich foam and thick foam when used. It is easy to delicately clean and rinses easily without leaving residue on the skin and is gentle on the skin.

After careful research, the inventors found that: by mixing a specific content and a specific ratio of alkyl ether carboxylic acid or its salt, alkyl glucoside and amphoteric surfactant in the composition, in the process of cleaning skin or hair, Rich foaming is obtained, that is, secondary foaming is performed on the basis of primary foaming, and its foaming amount is more than that of the first foaming. The texture of the foam is optimized, that is, a thick, fine, white and elastic foam can be obtained. The formed foam can cleanse the body meticulously, has good rinsing properties, is not easy to remain on the skin, and is gentle to the skin.

The detergent composition of the present invention contains the following components (A) to (D): (A) alkyl ether carboxylic acid or its salt 1.2 to 14 mass %, (B) alkyl glucoside 1.5 to 16.5 mass %, (C) ) 0.5 to 13.5 mass % of amphoteric surfactant, and (D) water, wherein the total content [A+B+C] of component (A), component (B) and component (C) is 6.2 to 22 mass %, The total content [B+C] of the component (B) and the component (C) is 5 to 18% by mass, and the ratio of the content of the component (A) to the total content of the component (B) and the component (C) [A/( B+C)] is 0.08-2, and the mass ratio [B/C] of the component (B) and the component (C) is 0.3-11.

The cleanser composition of the present invention can generate rich and thick foam by blending the above-mentioned components, contents and ratios, has excellent rinsing properties, does not leave active agents on the skin, is gentle on the skin after use, and can be worn on the skin. Comes with a smooth touch, especially suitable for children.
