Description

  The present invention relates to a laundry detergent composition using a clay mineral as a softening base.

  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 (for example, see Non-Patent Document 1), silicones such as poly (dimethylsiloxane) (for example, see Patent Document 2), and the like have been used. However, in a detergent composition in which a detergent and a softening agent are integrated, sufficient detergency and a softening effect have not been obtained.

In recent years, further studies have been made on methods for enhancing the softening effect of detergent compositions using clay minerals from the viewpoint of ease of blending and environmental friendliness. 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.

  In the physical properties of the sulfonic acid group and / or sulfuric acid group-containing polymer in the present invention, the physical property suitable for the expression of “slip property” is “spinning property”. The higher the spinnability polymer, the more “slip” can be expressed with a smaller amount.

That is, for example, “a polymer having an average molecular weight of 1,500,000 or more” refers to a polymer having a peak top molecular weight of 1,500,000 or more in terms of PEO equivalent molecular weight.
