Description

  The present invention relates to a softener composition.

Generally, a softener is blended with a fragrance in order to increase commercial value. In particular, in recent years, the number of products characterized by fragrance has increased, and products with various fragrances have been developed for differentiation. On the other hand, there is a technique (Patent Document 1, Patent Document 2) that increases the total blending amount of fragrances or increases the amount of persistent fragrance components in order to strengthen the remaining fragrance in clothing that is usually treated with a softener. . However, an increase in the blending amount of the fragrance becomes a problem in terms of cost, and even if the amount of the persistent fragrance component is increased, the balance of the fragrance composition is deteriorated, and as a result, a fragrance with good palatability may not be obtained. In particular, the aldehyde fragrance component in the long-lasting fragrance component is easily denatured by light, acid, etc., and the fragrance is modulated during storage, and as a result, the designed fragrance may not be sufficiently maintained. Further, fragrances such as heliotropin and hexylcinnamic aldehyde are preferable fragrances when imparting a residual scent to the treated cloth, but the stability in an acidic solution is poor and the expected residual fragrance cannot be obtained. Furthermore, there was a problem of deteriorating the hue of the liquid mixture.
