Description

Fabric softener composition {FABRIC SOFTENER COMPOSITION}

The present invention relates to a fabric softener composition, and more particularly to a fabric softener composition excellent in antibacterial and deodorant function.

Fabric softeners are widely used in homes to prevent static electricity generated in clothing and to give the flexibility of the fiber, the amount is increasingly used. Recently, with the improvement of consumers' standard of living, the desire for hygiene and cleanliness increases and the pursuit of a more comfortable medical life, there is a growing interest in preventing microbial growth and odor removal that can occur in clothing.

In general, when clothing is worn for a long time, or when clothing or textile products are incompletely dried during the rainy or summer season, bacteria or fungi are likely to proliferate, and odors may occur in the clothing and textile products. In this case, various diseases of the skin may be caused by bacteria or fungi propagated in clothing and textile products, and there is a problem that comfort may be impaired when wearing clothing due to bad smell.

In order to prevent the growth of bacteria and mold in clothing and textile products, a fabric softener composition applying an antimicrobial agent has been prepared. However, the antimicrobial agent applied to the conventional fabric softener composition is excellent in the antimicrobial activity of the raw material of the antimicrobial agent, but when applied to the fabric softener, there is a problem in that the antimicrobial activity is hardly exhibited due to its dilution ratio.

In the problem of removing odors, various methods have been used. Examples of the odor removal method include a chemical removal method, a physicochemical removal method, a sensory deodorization method, and a biochemical removal method. The chemical removal method uses chemical reactions such as neutralization, addition, polymerization, oxidation, reduction, or hydrolysis to decompose odorous substances by acting highly reactive substances on odorous components, or change into odorless compounds. It is a method of removing the substances causing them. The physicochemical removal method uses a compound having excellent adsorption and trapping ability, such as activated carbon, silica, or cyclodextrin, to adsorb or collect the odor causing component, or to remove the odor causing component with a high boiling point solvent or surfactant. Absorption is carried out by coating with a liquid paraffin, a higher alcohol, or a synthetic resin to remove. In addition, the sensory deodorizing method is a method of neutralizing the odor by using a fragrance fragrance with respect to the component causing the odor, or a sensory neutralization by masking the odor. Finally, the biochemical method is a method of blocking the generation of odor components by bacteria by antibacterial and bactericidal action such as amphoteric surfactants and fungicides, or decomposing organic acids known as odor causing substances by using digestive enzymes, bacteria and yeasts. to be.

Most of the odor that occurs in clothing and textile products is the sweat of the body, or most of the human body odor, and has been generally removed by washing or masking the smell as described above. However, when masking such an unpleasant odor, there is a disadvantage in that it interacts with the unpleasant odors, causing even more odor.

In view of the problems in the prior art as described above, an object of the present invention is to provide an excellent fiber softener composition excellent in antibacterial and deodorizing effect even in a small amount.

It is another object of the present invention to provide a fabric softener composition which removes unpleasant odors of fibers and microorganisms that breed in clothing to enable a comfortable medical life.
