Description

Solid soap composition containing the microemulsion

The present invention relates to a solid-state soap composition, a foam quality improving agent of their preparation and solid soap composition.

As the face or body skin cleansing composition such as such as a solid soap composition based on fatty acid salts have been used widely. Skin cleansing composition, in addition to detergency, it is also important that the feeling is excellent, foam quality and persistence of the foam (retention foam) that is required good. For example poor persistence of foam, if the bubbles disappear immediately, poor use feeling for resilient foam can not be maintained during the cleaning, also, sufficient cleaning feeling can not be obtained. In addition, foam is immediately friction better head retention because it takes the burden to the skin by the skin between (hands and face, etc.) is preferable to disappear. The foam quality, foam is resilient and spinnability have been a good quality foam, for the solid soap composition, studies have been made with respect to improvement of foam quality. For example, Patent Document 1, a fatty acid soap part, detergent composition comprising a granulated product comprising a water-soluble polymer having a foam quality improvement effect is described.

Microemulsion, exhibit transparent or translucent appearance, it is stable without separating, has the property of being able to formulate the water-soluble components and oil simultaneously. From such nature, cosmetics, in the preparation of liquid or gel detergent compositions, microemulsions are used. Patent Document 2, alkyl (oligo) Cosmetic detergent compositions containing microemulsion, anionic surfactants and cationic polymers containing glycoside or the like is described.
