Description

  The present invention relates to liquid softener compositions. In particular, the present invention relates to a liquid softener composition having good dispersibility, high freeze recovery, and reduced classification of blended capsule particles.

In recent years, consumers who use liquid softeners for the purpose of imparting a fragrance are increasing, and it is required that a good smell lasts. Although it has been tried to increase the blending amount of the flavoring agent in order to make the flavor last, the persistence of the flavor is not proportional to the amount of the flavoring, and the expected persistence can not be obtained. Therefore, it is practiced to use capsule particles in which a fragrance is contained.
The problem with using capsule particles is the dispersibility of the capsule particles in the liquid softener. As a technique for improving the dispersibility of capsule particles, a technique of adding a nonionic surfactant to an aqueous dispersion of capsules and redispersing (Patent Document 1) or a technique of matching specific gravity of a capsule-encapsulating fragrance and a liquid softening agent There are (Patent Document 2), and a technique (Patent Document 3) for devising the order of adding the compounding components.
