Description

[0001] Fabric softener composition [0002]

The present invention relates to a fabric softener composition capable of effectively removing a scent that has been changed.

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 microbial growth and removal of bad smell in clothing as consumers' desire for hygiene and cleanliness has been increased along with the improvement of living standards and pursuit of a more comfortable lifestyle.

Generally, the cause of the odor generated in the fibers is caused by the mixing of volatile organic compounds such as unsaturated lower fatty acids and ammonia, which are decomposed in the skin of the skin, and organic detergents such as sweat odor, and laundry detergent and residual fiber components in the fabric softener, In particular, it was reported that the drying time was delayed during drying in the rainy season, resulting in more odor generated by the odorant Morxella asloensis .

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, fiber softeners have been used as cationic surfactants for more than 60 years since they were commercialized worldwide in the 1950s. However, recently, such a cationic surfactant has been found to be toxic to human body, and the desire to avoid it is increasing.
