ABSTRACT:
This application claims priority from Japanese Applications JP 11-323,164, filed Nov. 12, 1999, JP 2000-102427, filed Apr. 4, 2000; and JP 2000-114,095, filed Apr. 14, 2000.
TECHNICAL FIELD
The present invention relates to a softener composition.
BACKGROUND ART
Heretofore, quaternary ammonium salts having long-chain alkyl group, acid salts of tertiary amines, etc. have been used for softeners. Further, compounding of a softener composition with an antimicrobial agent has been attempted for sanitation and deodorization of fiber products. JP-A 10-512015 discloses a softener composition comprising a water-insoluble quaternary ammonium salt as a softener and a water-soluble quaternary ammonium salt as an antimicrobial agent compounded therein. In addition, JP-A 7-3649 discloses a fiber product-softener composition, having pH 2 to 5, comprising a di-long-chain-alkyl amine (C
6-24
alkyl or alkenyl group which may be interrupted by an ether linkage, ester linkage or acid amide linkage) and a mono-long-chain-alkyl quaternary ammonium salt (C
6-24
alkyl or alkenyl group which may be interrupted by an ether linkage, ester linkage or acid amide linkage), at a weight ratio of from 9:1 to 5:5. WO 98/56886 discloses an antimicrobial fiber softener composition, being suitable for conferring antimicrobial performance on fibers, comprising a conventional fiber softener composition and one or more cationic antimicrobial agents in a larger amount than required for antimicrobial performance.
It, however, is a problem that such a composition is provided with only a small effect to suppress a nasty smell of clothes washed and dried in a room and a body smell derived from sweat at the time of wearing. Especially it has a low effect to chemical fiber clothes. It does not meet any of storage stability or a softening effect and the above mentioned smell-suppressing effect. Especially the softening effect is not sufficient to chemical fiber clothes.
DISCLOSURE OF INVENTION
Accordingly, the purpose of the present invention is to provide a softener composition which suppresses a body smell etc. of clothes, derived from sweat, and is excellent in the storage stability and the softening effect.
The present invention relates to a softener composition comprising:
(a) 3 to 50 percent by weight of a tertiary amine and/or a salt thereof, having an ester and/or an amide and at least one alkyl or alkenyl having 10 to 22 carbon atoms and (b) the below shown component and/or (c) the below shown component.
