Description

Description: FIELD OF THE INVENTION The present invention relates to a fabric softener composition. More specifically, the present invention relates to a liquid softener composition having a suppressed fatty acid odor. [0002] At present, the problems to be solved by the present invention,
Most of the products marketed as softeners for household use are mainly composed of quaternary ammonium salts having two long-chain alkyl groups in one molecule such as di (hardened tallowalkyl) dimethylammonium chloride. The composition was as follows. Further, conventionally, liquid softening finishes having various amines as softening bases have been known. This is because these bases have a good softening effect on various fibers even in a small amount. By the way, in addition to the purpose of imparting flexibility and antistatic property, the purpose of using the softening agent is to enjoy the scent during the washing process, drying and wearing. For this reason, most softening finishes contain fragrances, and various measures have been taken. Further, Japanese Patent Laid-Open Nos. 1-162872 and 5/1994
-98571, Japanese Patent Publication No. 62-8427, Japanese Patent Publication No. 52-34
No. 098 and the like disclose a soft finish containing an ester type base developed for the purpose of improving biodegradability and texture. Since the ester group is easily hydrolyzed during storage, it is necessary to devise the composition of the composition such as making the pH of the product acidic, and some of the technologies disclosed in the above publication are also disclosed. However, although it can be said that the storage stability in terms of flexibility is sufficiently ensured, fatty acids produced by hydrolysis during storage and fatty acids brought in as unreacted raw materials during base synthesis are There is a problem that it is present in the product and aggravates the odor. [0006] The problem to be solved by the present invention is to provide a liquid softening agent which improves the odor of the softening agent composition to enhance biodegradability and texture. The inventors of the present invention have made extensive studies in order to solve the above problems, and as a result, have found that the above objects can be achieved by combining extremely selected components.
