Description

  The present invention relates to a soft cleaning composition using clay mineral as a softening base, a soft cleaning method for textiles using the soft cleaning composition, and a softening effect enhancing method.

  Conventionally, a softening agent has been added to the cleaning agent to prevent the fiber product after washing from losing its softness due to dropping off of the fiber treatment agent or adhesion of salts, etc. Has been studied. As a softening agent that is deposited on the fiber surface and imparts flexibility to the texture of the fiber product, conventionally, a clay mineral such as smectite (see, for example, Patent Document 1), a cation interface such as a dialkyl type quaternary ammonium salt. Activators (see, for example, Non-Patent Document 1), silicones such as polydimethylsiloxane (see, for example, Patent Document 2), and the like have been used. However, sufficient flexibility has not been achieved.

In recent years, methods for enhancing the softening effect of clay minerals have been studied from the standpoint of ease of blending and environmental response. For example, a combination of bentonite and a pentaerythritol compound (for example, see Patent Document 3), a combination of a clay mineral and a flocculant (for example, see Patent Document 4), a combination of bentonite and a soluble potassium salt (for example, Patent Document 5, Non-Patent Document 1) is known. However, it has not yet been provided with sufficient flexibility in the cleaning process.
