Description

This invention relates to a liquid fabric softener composition and a method for inhibiting the proliferation of Moraxella osloensis. When wet textile products are dried in damp environments such as indoors, they are prone to developing a musty odor. To suppress the growth of microorganisms that cause this odor and thus prevent its occurrence, textile products are sometimes treated with a liquid fabric softener composition that has antibacterial properties. Amine compounds having one to three long-chain hydrocarbon groups separated by ester or amide groups, their salts, and their quaternary derivatives function as softening base materials in liquid fabric softener compositions and also exhibit antibacterial activity. Furthermore, liquid fabric softener compositions may contain a single-chain quaternary ammonium salt having one long-chain hydrocarbon group as an antibacterial agent (Patent Documents 1-2). However, while these ingredients are effective against Staphylococcus aureus, they have a problem in that they are not very effective against Moraxella osloensis (hereinafter also referred to as "M. osloensis"), which is the main cause of the musty smell of damp clothes. Patent Document 3 describes combining two specific quaternary ammonium salts with calcium and magnesium under specific conditions in order to suppress the growth of M. osloensis and impart antibacterial and deodorizing effects to clothing. However, consumers' concerns about odors in their clothing have not been completely resolved, and further improvements in performance are desired.

[Liquid fabric softener composition] A liquid softener composition according to one embodiment of the present invention comprises component (A), component (B), and component (C). <(A) Ingredients> Component (A) is at least one compound selected from the group consisting of amine compounds having 1 to 3 hydrocarbon groups having 10 to 26 carbon atoms separated by an ester group (-COO-) and/or an amide group (-NHCO-), salts thereof, and quaternary compounds thereof. (A) Component is a softening base material and is added to the liquid fabric softener composition to impart the effect of giving softness (texture) to textile products. The number of carbon atoms in the hydrocarbon group having 10 to 26 carbon atoms (hereinafter also referred to as the "long-chain hydrocarbon group") is preferably 14 to 22, and more preferably 16 to 20. When the number of carbon atoms is 10 or more, the flexibility-imparting effect is good, and when it is 26 or less, the handling properties of the liquid softener composition are good. The long-chain hydrocarbon group may be saturated or unsaturated. If the long-chain hydrocarbon group is unsaturated, the position of the double bond may be anywhere, but if there is one double bond, it is preferable that the double bond is located in the center or around the center of the long-chain hydrocarbon group. The long-chain hydrocarbon group may be a linear hydrocarbon group or a hydrocarbon group containing a ring in its structure, and is preferably a linear hydrocarbon group. The linear hydrocarbon group may be linear or branched. The linear hydrocarbon group is preferably an alkyl group or an alkenyl group, and more preferably an alkyl group. The long-chain hydrocarbon group is fragmented by a fragmenting group. Fractionation may occur at one location or at two or more locations. Preferably, it occurs at one location. The cleaving group is either an ester group (-COO-) or an amide group (-NHCO-). When a long-chain hydrocarbon group has two or more cleaving groups, each cleaving group may be the same or different. Furthermore, the carbon atoms in the fragmentation group shall be counted in the number of carbon atoms of the long-chain hydrocarbon group. Long-chain hydrocarbon groups are typically introduced by using unhydrogenated fatty acids derived from beef tallow, fatty acids obtained by hydrogenating or partially hydrogenating the unsaturated portion, unhydrogenated fatty acids or fatty acid esters derived from plants such as palm oil and oil palm, or fatty acids or fatty acid esters obtained by hydrogenating or partially hydrogenating the unsaturated portion. In amine compounds (hereinafter sometimes simply referred to as "amine compounds") having 1 to 3 hydrocarbon groups having 10 to 26 carbon atoms separated by ester groups (-COO-) or amide groups (-NHCO-), the number of long-chain hydrocarbon groups is 1 to 3. Preferably, there are 2 (secondary amine compounds) or 3 (tertiary amine compounds), and more preferably 3. Examples of amine compounds include the compound represented by the following formula (A1). (In the formula, R5 to R7 are each independently -CH2CH ( Y1 ) OCOR10 ( Y1 is a hydrogen atom or CH3 , and R
