Description

[Technical Field]

[0001] This invention relates to a detergent composition. [Background technology]

[0002] Swelling clay minerals have the property of thickening compositions and adsorbing sebum, so when incorporated into cleansing agents, they can effectively remove dirt from pores. For example, Patent Document 1 describes a paste-like detergent composition containing a fatty acid potassium salt mixture, an alkyliminodicarboxylic acid type amphoteric surfactant, an acylmethyltaurine type anionic surfactant, a water-swellable clay mineral, and a divalent or trivalent alcohol, which exhibits excellent spreadability, rapid foaming, foam volume, and foam quality during use, and provides a refreshing feeling after rinsing while being less likely to cause tightness.

[0003] [Patent Document 1] Japanese Patent Publication No. 2014-193981 [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] However, conventional detergent compositions, even those containing clay minerals, did not produce any noticeable change in feel during use, and as a result, none allowed users to experience the sebum-absorbing effect of clay minerals. Therefore, from the perspective of user experience, there was a need for a detergent that allowed users to feel the effects of clay minerals and more clearly experience their sebum-absorbing effect. In addition, detergents containing clay minerals had issues with dispensing when filled into containers and separation when stored at high temperatures, indicating challenges with storage stability. [Means for solving the problem]

[0005] The inventors of the present invention have discovered that by using a combination of fatty acids and their salts with a specific amount of clay minerals, a cleansing agent composition can be obtained that provides a pleasant rough texture when applied to the skin and massaged, and that exhibits excellent dispensability from the container after storage and superior storage stability, thereby completing the present invention.

[0006] The present invention relates to the following components (A) and (B): (A) Clay minerals 2-8% by mass, (B) General formula (1): R 1 -COOX (1) (In the formula, R 1 (where X represents an alkyl or alkenyl group having 9 to 23 carbon atoms, and X represents a hydrogen atom, alkali metal, ammonium, ammonium derived from an alkanolamine, or a basic amino acid.) Fatty acids and their salts represented by the following symbols This relates to a detergent composition containing [a specific ingredient / material]. [Effects of the Invention]

[0007] The cleansing composition of the present invention provides a pleasant rough texture due to the clay minerals when applied to the skin and massaged, and exhibits excellent dispensability from the container at room temperature and low temperatures after storage, as well as particularly good storage stability at high temperatures. Furthermore, when the cleansing composition is massaged onto the skin with water, it does not immediately lather, allowing for a thorough massage in a creamy or gel-like state, and providing a satisfying massage sensation while feeling the rough texture of the clay minerals on the skin.
