Description

  The present invention relates to a softener composition.

 Usually, the softener composition contains a quaternary ammonium salt having two long-chain alkyl groups in one molecule as a main component, but the quaternary ammonium salt is insoluble in water. An emulsified form is known. For this reason, the softening agent composition is required to have high storage stability that has a low viscosity immediately after preparation and that does not increase in any environment. In particular, a softener composition mainly composed of a quaternary ammonium salt having a hydrocarbon group having an ester group or an amide group at any position of the alkyl chain is likely to thicken because hydrolysis occurs during long-term storage. . As a means for solving this problem, Patent Documents 1 and 2 disclose compositions containing an inorganic salt or an organic acid salt for the purpose of preventing gelation or reducing the viscosity of the softener composition immediately after adjustment. Patent Document 3 describes that the pH of the softening agent composition is adjusted to be acidic for the purpose of improving storage stability.
