Description

[0001] Fabric softener composition [0002]

The present invention relates to a fabric softener composition.

Textile softeners are widely used in households to prevent static electricity generated in clothes and to impart flexibility to fibers, and the amount thereof is gradually increasing. In recent years, there has been an increasing interest in prevention of the growth of microorganisms and the removal of offensive odors, as consumers' living standards are improved, hygienic and cleanliness requirements are increased, and more comfortable lifestyle is pursued.

Generally, the organic odor generated in fibers is caused by organic compounds such as sweat odor reacting with volatile organic compounds such as unsaturated lower fatty acids and ammonia formed by decomposition of the skin upright bacteria or reacting with laundry detergent or residues of fabric softener . Especially in the case of rainy season, drying time is delayed during drying in the room, so it is known that odor generated by Morxella asloensis, which is an odor bacterium, is generated more.

Conventionally, a fabric softener composition containing an antimicrobial agent has been used to remove such odor, but the antimicrobial agent contained in the conventional fabric softener is harmful to human body. In recent years, the use of synthetic antimicrobial agents has been reported to be harmful to human body. Therefore, the use of such antimicrobial agents is being avoided.

In addition, textile softeners have been commercially available worldwide in the 1950s and have used cationic surfactants as softening agents for over 60 years (Patent Document 1). However, recently, such a cationic surfactant has been found to be toxic to human body, and the desire to avoid it is increasing.
