[0001] The present invention relates to a softener composition.

[0002]

2. Description of the Related Art
As the softener, a quaternary ammonium salt having a long-chain alkyl group or an acid salt of a tertiary amine is used. Attempts have also been made to blend an antimicrobial agent into the softener composition from the viewpoint of hygiene and deodorization of textile products. JP-A-10-512015 discloses a softener composition containing a water-insoluble quaternary ammonium salt as a softener and a water-soluble quaternary ammonium salt as an antibacterial agent.

[0003] However, such a composition has a low effect of suppressing malodor attached to clothing, such as an unpleasant odor when dried indoors after washing and a body odor caused by sweat when worn.
In particular, there is a problem that the effect on synthetic textiles is low. In addition, the storage stability of the composition is not yet at a satisfactory level.

[0004] Accordingly, an object of the present invention is to provide a softener composition which has a high effect of suppressing odors attached to clothing such as body odor due to sweat and is excellent in storage stability even in synthetic textiles. .

[0005]

The present invention relates to (a) a tertiary compound having an ester group and / or an amide group in the molecule and further having at least one alkyl or alkenyl group having 10 to 22 carbon atoms. 3 to 50% by weight of an amine or a salt thereof, (b)
Provided is a softener composition containing the compound of the following general formula (1) and / or the compound of the general formula (2) in an amount of 0.1 to 15% by weight.
