Detergent composition comprising an amphoteric surfactant system

The invention relates to a substantially nonaqueous skin cleansing composition comprising a granulated product obtained by granulating particles of a surfactant selected from the group consisting of nonionic surfactants, amphoteric surfactants and anionic surfactants with a binder. The composition scarcely causes damage to and itch on the skin, can give an effective massaged feeling and has excellent cleanability.

Skin cleansing composition

The invention relates to disintegrating particles formed by agglomerating primary particles at least part of which are insoluble in water, wherein the agglomeration of the disintegrating particles is disintegrated in an aqueous solution containing a water-soluble salt by lowering the concentration of the water-soluble salt. The invention also relates to a cleanser or detergent composition that includes the disintegrating particles, a water-soluble salt at a concentration lower than its saturated solubility, a surfactant and water. The composition has excellent physical (mechanical) cleanability and stability with time and gives users a pleasant feeling upon use. The composition does not cause damage to and itch on the skin because the disintegrating particles are disintegrated during cleansing and rinsing, and it is extremely good in rinsability.
