[0002]

2. Description of the Related Art Conventionally, detergent compositions used for cleaning the body and hair have been studied for their excellent foaming and foam creamy properties. However, with the diversification of consumers' preference, it is composed of a combination of currently known detergent compositions such as soap, N-acyl amino acid salt, amide ether sulfate, alkyl ether sulfate, alkyl glycoside and the like. The detergent composition has stability over time, foaming and foam stability, creamy feeling of foam, feel at the time of rinsing (no slimy feeling), and feel after rinsing (not squeezing, but moist and smooth). It cannot be said that either of the points is sufficiently satisfied. Thus, a foaming composition and foam stability are remarkably good, the stability over time is remarkably excellent, the creamy feeling of the foam is remarkably excellent, and a detergent composition having a sufficiently good feel at the time of rinsing and after rinsing is still being developed. The reality is that they do not, and there has been a strong demand for improvement. In particular, in the feeling after rinsing, the fact is that no detergent composition has been developed yet, which gives a refreshing feeling without being taut and at the same time a moisturizing and smooth feeling that is contrary to each other.

If it exceeds, the effect corresponding to it cannot be obtained.

The detergent composition of the present invention may contain a specific amphoteric surfactant in addition to the constituents of claim 1. The compounding of the amphoteric surfactant increases the rich feeling in the foam characteristics, and it is desirable to mix it depending on the use. The amphoteric surfactant is appropriately selected from the group of usual one-chain one-polar group-containing amphoteric surfactants such as imidazoline-based amphoteric surfactants and betaine-based amphoteric surfactants, excluding lecithin which is a two-chain type compound. . The content is 0.5 to 10% by weight in the present cleaning composition.

The detergent composition of the present invention may contain 0.5 to 40% by weight of a compound having three or more hydroxyl groups in the molecule. Examples of compounds having three or more hydroxyl groups in the molecule include glycerin, diglycerin, 1,3
-But not limited to polyhydric alcohols such as butylene glycol and sugar compounds. This formulation increases the physical stability of the detergent composition, and it is desirable to blend it depending on the application.

The detergent composition of the present invention has the composition as described above, but if necessary, other surfactant, emulsification aid,
Fragrances, colorants, preservatives, pigments and the like can be appropriately added within the range where the object of the present invention is achieved. INDUSTRIAL APPLICABILITY The detergent composition of the present invention is applied to a general cosmetic detergent composition for cleaning face cleansing cream, liquid face wash, body shampoo, shampoo, cleansing lotion, bar soap and the like.
