Abstract

The present invention can be used as a fungicide and can be used as a softening agent of a fabric softener by substituting a cationic surfactant with a skin-stimulating cationic surfactant in a water-soluble polymer as a softening agent, Reduces the friction of the skin as much as possible and absorbs sweat more easily than conventional cationic surfactant type softener, so that it does not irritate the skin.

Description

[0001] The present invention relates to a fabric softener composition comprising a viscous polymer as a main component,

The present invention features a fabric softener composition that provides the flexibility of a fabric softener with a polymer that exhibits a viscosity without using a cationic surfactant. Examples of the macromolecule that exhibits viscosity in water include guar gum and guar gum derivatives, agar, gelatin, gum arabic, locust bean gum, carbopol, hydroxyethyl cellulose, carbomer and the like.

This fiber fabric softener composition is used as a softener in place of a cationic surfactant and is usually used as a thickening agent. It is safer to the human body, has less irritation to the skin, and has a sensitive skin or a more safe ingredient. Suitable for people.

In the case of conventional softeners, almost all of the fabric softeners basically contain cationic surfactants as softeners.

Cationic surfactant means that when the surfactant is dissolved in water, the atomic group that is dissociated and exhibits the surfactant has a positive charge. Cationic surfactants are used as softeners and antistatic agents because they are well adsorbed to negatively charged fibers in water by reverse osmosis soap and exhibit flexibility, antistatic properties and water repellency of the fibers. Generally, since bacteria have a negative charge, cationic surfactants strongly adsorb bacteria to eliminate active functions, and thus they are also used for sterilization and disinfection purposes.

 Representative cationic surfactants include amine salts and quaternary ammonium salts.

Since the amine (R-NH ₂ ) is a base, it reacts with acid to form a salt (RNH ₂ · HX). Such amine salts having long alkyl groups are used as surfactants.

A quaternary ammonium salt (quaternary ammonium salt) in which all four hydrogen atoms of a quaternary ammonium salt (NH ₄ ⁺ ) are substituted with an alkyl group or an alkylaryl group is one of important cationic surfactants.

Wherein R ₁ and R ₂ are CH ₃ ^- or C ₂ H ₅ ^- , R ₃ and R ₄ are C ₈ -C ₁₈ alkyl or aryl groups, and X is Br or Cl.

CH₂-)를 가지고 있는 것은 강한 살균력을 가지고 있다.Textile softeners Most of the surfactants used as softening agents and antistatic agents are these quaternary ammonium. One of the alkyl groups in the quaternary ammonium salt is a benzene group (

CH ₂ -) have strong sterilizing power.

Ammonium salt compounds such as dimethyl dialkylammonium chloride (DDAC) have been used as cationic surfactants used in fabric softeners. However, since they have low biodegradability, cationic surfactants having a functional group capable of decomposing in the alkyl group such as ester or amide Quaternary ammonium salts, quaternary ammonium salts of amido ester amines, imidazoline and imidazoline ester based cationic surfactants have been developed. In the case of imidazolinium salt, the imidazole group is hydrolyzed and the biodegradability is poor in the aqueous solution. Triethanolamine and fatty acid are reacted with each other, and quaternized to form ester imidazoline. However, imidazoline ester has good biodegradability but low flexibility.

Recently, the Ester Quat series has been widely used. DDAC-based fabric softener used as a disinfectant has high viscosity and high stability of the product, but it is environmentally problematic and its harmfulness is suggested. A Study on Inhalation Toxicity Screening Techniques for Assessment of Mixture Hazards by the National Institute of Environmental Research, 2014 (Ⅰ) Studies have shown that DDAC or DDAC + EG may cause pulmonary fibrosis. Ethylene oxide (EG) is also a commonly used ingredient in softeners. If the product is used for a long period of time with spray or fumigation, it can be extremely fatal to the human body.

The ester quater is a cationic surfactant mainly used in softeners. It is produced through an ester exchange reaction between an oil and an amine. In this case, the oil content of untranslated triglyceride is so high that the quality of the fabric softener is poor.

US Patent No. 5,637,743 uses a strong alkaline catalyst to improve this disadvantage. Partially hydrogenated palm oil and sodium methylate are used as a catalyst in triethanolamine. , Followed by an ester exchange reaction, followed by ester exchange reaction using a hypophosphorous acid as a catalyst in a mixture of dimethylaminopropylamine and triethanolamine, followed by quaternization with dimethylsulfate .

The triethanolamine used at this time shows symptoms of systemic toxicity at high exposure levels and weak skin irritation at repeated exposure through the skin pathway, the National Institute of Environmental Research reported.

The ester quater uses a lot of nonionic surfactant for the stability of the product, so the rinse water is foamy and the detergent component remains on the clothes except the cationic surfactant.

Also, in the case of cationic surfactant fabric softener, it may cause irritation when the pH of the product is 2 to 3 on the skin, and because of low hygroscopicity of the fiber, it inhibits sweat absorption, which causes skin trouble such as rash or bacterial infection .

Even when the fabric softener is not used, the aging of the fiber can cause irritation to the skin as the rough fiber and the skin are frictioned.

Therefore, a good fabric softener does not inhibit the hygroscopicity, and it can be said that the rough fiber reduces the friction of the skin by adding the softening power to the harmless components.

The present invention relates to a fiber softener composition which is safer for skin, which gives flexibility to fiber with a component used for food among polymers showing increase by melting in water instead of a cationic surfactant which is a raw material of bactericide.

The seeds of Gua bean have very good characteristics. The seeds of guacapone contain very large endosperm, which consists of very large polysaccharides of galactose and mannose. These polysaccharide polymers are water-soluble and exhibit a viscous effect in water. Due to these characteristics, guar gum has been added to foods for a long time.

Cationic guar, which is prepared to have cations after reacting with cations in guar gums, has been generally used for the incremental effect of products in household goods.
