Description

  The present invention relates to a cleaning composition.

  Conventionally, clay minerals have been blended into cosmetics using properties such as swelling and thickening. When clay minerals are blended, the liquidity of the cosmetics changes, and the sensory characteristics are as follows: (1) no stickiness, smooth and refreshing feel, (2) improved stability of emulsions and suspensions, (3 ) The effects of improving cleansing performance such as face washing and shampoo are exhibited. In particular, even when it is blended into a washing agent such as a skin cleanser, there is an advantage that there is no stickiness when rinsing and a smooth feel is given to the washed skin. However, in detergents that contain a large amount of surfactant, silicone, etc., the electrolyte and organic matter coexist, so the clay mineral tends to agglomerate, resulting in decreased dispersion stability and foam creamy. There arises a problem that the quality and feel after use are inferior.

  In order to solve such problems, an anionic surfactant, a water-swellable clay mineral, a specific nonionic polymer and a nonionic surfactant are used to maintain excellent dispersion stability under various conditions. A liquid detergent composition for skin and hair containing a specific anionic polymer is exemplified (for example, see Patent Document 1). Moreover, the detergent composition containing a water-soluble nonionic polymer compound and a water-soluble anionic polymer compound is illustrated by the emulsion composition containing a silicone and a water-swellable clay mineral (for example, patent document 2). See). Furthermore, a detergent composition containing one or more types of clay minerals having different swelling powers, a surfactant, an anionic polymer and / or a nonionic polymer is exemplified (for example, see Patent Document 3). .

  However, although the above-mentioned attempts can improve the dispersion stability of the composition to some extent, in addition to poor water familiarity during foaming, there is a problem that foaming power is reduced and stickiness after washing occurs. is there. In addition, the storage stability over time is not fully satisfactory.
