Description

  TECHNICAL FIELD The present invention relates to a creamy skin cleanser composition, and more particularly, a creamy skin cleanser that does not become wet when rinsed, has a refreshing finish, and has good foaming and foam quality (creaminess). The agent composition.

  Conventionally, in a skin cleanser composition, it is possible to improve foaming, foam quality (creaminess), cleaning power, feel during use, etc. by combining a water-soluble polymer and a surfactant. It has been known. For example, a skin cleansing composition containing a dimethyldiallylammonium chloride / acrylamide copolymer (polyquaternium-7), which is a water-soluble polymer, is disclosed (see Patent Document 1). However, when such a water-soluble polymer is contained, there are also disadvantages such as slickness at the time of rinsing and a refreshing feeling after washing. In other words, there was no technology that could simultaneously satisfy foaming, foam quality (creaminess), no slickness at the time of rinsing, and a refreshing wash, which was not satisfactory.

  Also, cosmetics containing cationized guar gum, cationized locust bean gum, cationized tara gum, etc. for the purpose of providing a moist feeling while giving the skin a feeling of elasticity and plumpness after use. Although a composition has been disclosed (see Patent Document 2), the use of the composition does not change the point that the polymer feels sticky or feels after-residue, and there is no improvement in foaming or foam quality. Absent. That is, there is no technology that achieves both improvement of foaming and foam quality (creamy property) and lack of luster when rinsing.

JP 2005-154360 A JP 2006-62979 A

  Therefore, in view of the above circumstances, the present inventors have intensively studied.As a result, in the skin cleanser composition containing a surfactant, by blending a specific cationized polysaccharide, there is no moisture when rinsing, It has been found that both foaming and foam quality (creaminess) can be satisfactorily achieved while having a refreshing washing, and the present invention has been completed.

  That is, an object of the present invention is to provide a cream-like skin cleanser composition having good foaming, foam quality (creaminess), no slickness during rinsing, and a refreshing finish. is there.

  This invention achieves the said objective by containing fatty acid soap and the cationized polysaccharide whose nitrogen content is 2-4 mass% in a creamy skin cleansing composition.
