  Patent Document 1 discloses a technique in which a fatty acid is used in combination for the purpose of improving the softening effect of a liquid softening agent composition mainly containing a biodegradable quaternary ammonium compound having an ester group. In addition, since quaternary ammonium compounds having an ester group undergo hydrolysis of the ester group during storage, the hydrolysis can be suppressed by adjusting the pH to acidic as described in Patent Documents 2 and 3. Has been done.

  On the other hand, in recent years, a softener composition having a transparent or translucent appearance has been developed from an aesthetic point of view. In Patent Documents 4 to 11, a quaternary ammonium compound having an ester group and a specific LogP are used. A technique using a solvent is disclosed. Moreover, these transparent softening agent compositions are also adjusted to acidic pH for the purpose of suppressing hydrolysis.

When such a liquid softener composition contains a fatty acid, a composition having a transparent appearance can be obtained at the initial stage of blending, but white turbidity and separation are caused during storage.

As a result, even if it contains a fatty acid, there is no problem in storage stability, and it is considered that the effect of improving the softening effect by using the fatty acid can be obtained.

  The compositions of Examples 1 to 6 had no change in appearance at all immediately after production and after storage. Moreover, even when a pair of compositions immediately after production and after storage were compared, the appearance was exactly the same.

In addition, when the softness | flexibility evaluation was performed like the softness | flexibility evaluation method of the Example description of Unexamined-Japanese-Patent No. 2004-84144 using the composition of Examples 1-6, the softness | flexibility effect excellent with respect to the textiles was carried out. It was confirmed to have
