Description

[0001] The present invention relates to a fabric softener composition comprising a polymer having viscosity and lecithin as main components,

The present invention is characterized by a fabric softener composition which is free from the use of a cationic surfactant and has a viscosity and a small amount of lecithin dissolved in water to be used in foods and is effective in preventing softening of the fabric softener and prevention of static electricity. 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 a safe and chewy skin for people who have sensitive skin and a more safe ingredient because of the use of polymer and natural surfactant lecithin as an effective ingredient instead of cationic surfactant. Suitable for people who need it.

Conventional softeners basically contain a cationic surfactant as a flexible component.

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.

Cationic surfactants are generally used for the purpose of disinfectants and disinfectants since they strongly adsorb bacteria with negative charges and thus eliminate active functions.

 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). This amine salt having a long alkyl group is used as a surfactant.

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.

Conventionally, cationic surfactants used in fabric softeners include ammonium salt compounds such as dimethyl dialkylammonium chloride (DDAC). However, since they have low biodegradability, cationic surfactants having a functional group capable of decomposing into an alkyl group Quaternary ammonium salts of surfactants, quaternary ammonium salts of amidoesteramines, 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.

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 the Assessment of Mixture Hazards in 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.

Ester Quat is a cationic surfactant mainly used in softeners. It is produced through ester exchange reaction between oil and amine. Since the content of untranslated triglyceride oil is high, the quality of fabric softener is poor. Have.

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 .

According to the National Institute of Environmental Research, triethanolamine shows symptoms of systemic toxicity at high exposure levels and weak skin irritation at repeated exposure through skin pathways.

In addition, ester quaternaries use nonionic surfactants in order to stabilize the product. If nonionic surfactant is used, the rinse water will be foamy and the nonionic surfactant and nonionic detergent components will remain on the fibers, which may cause another irritation of the skin.

In the softener which does not contain the cationic surfactant, a large amount of nonionic is used for the purpose of solubilizing the fragrance, so that the bubble in the final rinse water has a disadvantage that it becomes worse than the conventional cationic surfactant fabric softener.

Cationic surfactant fabric softener may cause irritation when the product comes in contact with the skin at a pH of 2 to 3, and since the fiber treated with this fabric softener has a low hygroscopicity, it inhibits sweat absorption. Can cause skin troubles.

If you do not use a fabric softener, it can irritate your skin as it aggravates rough fibers and skin.

Therefore, a fabric softener with the least irritation to the skin can be said to coat fibers with a safe ingredient without impairing hygroscopicity.

The present invention relates to a fabric softener composition which is used for food instead of a cationic surfactant which is a raw material of a bactericide, and is more safe for skin, which contains a small amount of lecithin in a polymer which shows an increase in water and dissolves in water to give flexibility and antistatic effect.

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

Cationic guar, which is made to have cations after reacting with cations in guar gums, has been generally used for the incremental effect of products in household goods. U.S. Patent No. 4,661,267 uses a cationic guar as a antifouling agent for liquid fabric softening agents, and Japanese Patent Laid-Open No. 10-2014-0042866 discloses a method for producing a non-cellulosic polysaccharide (guar, galactomannan) containing a cationic group Conditioning effect of hair and hair and scalp care.
