Disclosure of Invention
When people wash the body with the shower gel, in order to clean the body, people usually use tools or free hands to beat abundant foams. However, in the case of letting children wash their bodies independently, it is found that the children do not hit the foam well on the bodies. For example, children often take insufficient amounts of body wash, so that the generated foam cannot be washed all over the body, and thus the body cannot be washed clean; alternatively, although the amount of foam generated can cover the entire body, the child spends too long washing a certain part of the body, and the foam attached to the remaining part disappears, and thus the effect of washing cannot be achieved. In patent documents 1 and 2, there is no description about improvement of foaming property of the detergent composition.
The object of the present invention is to provide a detergent composition which can generate abundant foam and has a thick foam texture when used. It is easy to wash finely, and it is easy to rinse without leaving residue on the skin, and is mild to the skin.
The inventor finds that: by blending the alkyl ether carboxylic acid or a salt thereof, the alkyl glucoside and the amphoteric surfactant in a specific amount and a specific ratio in the composition, abundant lathering can be obtained in the process of cleansing skin or hair, that is, secondary lathering is performed on the basis of primary lathering, and the lathering amount is larger than that of the primary lathering. The texture of the foam is optimized, and the fine, white and elastic thick foam can be obtained. The foam formed can be used for finely cleaning the body, has good washability, is not easy to remain on the skin, and is mild to the skin.
The detergent composition of the present invention contains the following components (a) to (D): (A) 1.2 to 14% by mass of an alkyl ether carboxylic acid or a salt thereof, (B) 1.5 to 16.5% by mass of an alkyl glucoside, (C) 0.5 to 13.5% by mass of an amphoteric surfactant, and (D) water, wherein the total content [ A + B + C ] of the component (A), the component (B), and the component (C) is 6.2 to 22% by mass, the total content [ B + C ] of the component (B) and the component (C) is 5 to 18% by mass, the ratio [ A/(B + C) ] of the content of the component (A) to the total content of the component (B) and the component (C) is 0.08 to 2, and the mass ratio [ B/C ] of the component (B) to the component (C) is 0.3 to 11.
The cleansing composition of the present invention can produce rich and thick foam by blending the components of the above composition, content and ratio, has excellent rinsing property, does not leave an active agent on the skin, is mild to the skin after use, can give a smooth touch, and is particularly suitable for children.
