Description

TECHNICAL FIELD The present invention relates to an antimicrobial and deodorant fiber softening composition containing a chaff extract as an active ingredient,

The present invention relates to a fabric softener composition comprising a chaff extract as an active ingredient.

Textile softener is a material that binds to fibers and imparts a soft touch, and is primarily intended to impart flexibility and antistatic properties. In addition, the added flavor and color gives added effect by refreshing. The fabric softener contains cationic surfactant and fragrance, stabilizer, acidity regulator, preservative, and additives for functionalization.

Cationic surfactants, which are the main constituents of fabric softener, use quaternary ammonium salts, which are effective in removing detergent residues in fabrics, but are known to have the highest skin irritation among surfactants and pruritus to sensitive skin .

As described above, there are many kinds of cationic surfactants used as the base compound of the fabric softener, but dimethyl ammonium chloride has been used for 30 years or more. These bases exhibiting cationic properties are adsorbed on a fabric charged with anion, so that the friction coefficient of the surface of the fabric is lowered according to the lubricating effect of the two long chain alkyl groups, thereby exhibiting a softening effect.

The role of the fabric softener is to provide soft spots and softening effect, and antistatic effect. It also softens the fiber pieces and shortens the drying time.

However, when a conventional cationic surfactant is used, a hydrophobic alkyl group is present on the surface of the fiber to lower the water absorption, thereby deteriorating the moisture absorption of the sweat. In addition, since the base material of the softener is a cation, the anion and adduct of the detergent component remaining in the washing step And a problem of deteriorating the softening effect has been found. In addition, since the base material of the fabric softener is insoluble in water, a dispersant is usually formulated into a fine dispersion of 4 to 6%.

As a result of concerns about chemical hazards and the demand for natural materials, textile softeners that replace cationic surfactants, which are major components of fabric softener, with organic acids and vinegar have gained popularity in the market. Fermented vinegar contains several dozens of organic acids such as acetic acid, citric acid and various amino acids, which not only stimulates metabolism but also acts as a powerful preservative and disinfectant. In addition, vinegar has also been able to remove the detergent residue, soften the fabric and soften the softener, so that a fabric softener containing vinegar has been developed (Korean Patent Laid-Open No. 2015-0100547). Generally, The generated odor is generated by reaction with a volatile organic compound such as an unsaturated lower fatty acid and ammonia produced by decomposition of an organic compound, which is a component of perspiration odor, by a skin-damaging bacteria, or by reacting with a laundry detergent or a residual component of a fabric softener. Especially in the rainy season, it is known that the drying time is delayed, and the odor generated by the bacteria is further generated. When the fabric softener using vinegar is used, the sterilizing ability of the vinegar plays a role of removing the smell.

The present inventors have intensively studied to develop a fabric softener which does not contain a preservative, an artificial coloring matter and a cationic surfactant, and it has been found that when containing a chaff extract, It is confirmed that an environmentally friendly fabric softener can be produced without being irritating, and the present invention has been completed.

Accordingly, an object of the present invention is to provide a fabric softener composition comprising a chaff extract as an active ingredient.

The cooling water temperature of the rice husk hypochlorite condenser was in the range of 15 ~ 43 ℃. The crude sap was used as a sample after being subjected to a distillation under reduced pressure for use in this experiment. The manufacturing process of the rice husk carbonization plant consists of a rice hull tank, a carbonization furnace, a smelting furnace, a cooling system and a super-liquid condenser.

As a result, as shown in Fig. 1, it has antibacterial activity against Salmonella typhimurium, Bacillus cereus, Listeria monocytogenes, and Escherichia coli Respectively.

1.2. Identification of antioxidant activity of chaff extract
