2. Description of the Related Art
Commercially available products as household softening agents generally have a composition containing di (hardened beef tallow alkyl) dimethylammonium chloride as a main component. The reason for this is that this quaternary ammonium salt exerts a good softening effect on various fibers even in a small amount. However, the fourth
Although the high-grade ammonium salt has a high softening effect, if it is treated at a high concentration in order to obtain a higher softening effect, its elasticity may be reduced especially for cotton and the texture may be impaired. Further, the softener composition using the quaternary ammonium salt may easily thicken, become a gel or separate due to its physicochemical properties when stored for a long period of time. In addition to the above-mentioned quaternary ammonium salt, polyoxyethylene-based nonionic activators, additives such as electrolytes and solvents are added to commercially available softeners to improve long-term storage stability. The effect is still insufficient.

Further, in order to improve the drawbacks of the conventional quaternary ammonium salt by introducing an ester group between the quaternary nitrogen atom and the long-chain alkyl chain, various softening agents have been proposed. There is. For example, JP-A-3-90677 discloses a softener composition using an ester group-containing quaternary ammonium salt which is well dispersed without gel formation, and JP-A-1-162872 discloses a high temperature storage. Disclosed is a softener composition using an ester group-containing quaternary ammonium salt, which has good viscosity stability at the time. However, the softening finish containing these quaternary ammonium salts has a softness, storage stability and water absorption (fibers treated with a softening finish having poor water absorption tend to repel water,
It was still unsatisfactory).
Therefore, an object of the present invention is to provide a liquid softening agent composition exhibiting sufficiently satisfactory performances in terms of softening performance, storage stability and water absorption, and having excellent biodegradability and being friendly to the natural environment. is there.
