Description

Fabric softener composition {FABRIC SOFTENER COMPOSITION}

The present invention relates to a fabric softener composition, and more particularly, to a fabric softener composition which is not only excellent in flexibility and absorbency of clothes, but also significantly improved in storage stability.

Cationic dialkyldimethylammonium salts (JAOCS 61, 367 (1984) and JAOCS 65 (10), 1682 (1988)), reported by the American Petroleum Institute, have been used for a long time as a major component of general fabric softeners. Cationic surfactants containing functional groups capable of biodegrading, such as ester groups, have been developed and used because of their low biodegradability.

N-methyl, N, N-di- (C _{14-18 -acyloxy} ethyl), N-hydroxy ethyl ammonium as one of the surfactants containing intramolecular ester bonds among the cationic surfactants developed for environmental friendliness Methosulfate has been applied to fabric softeners. These cationic surfactants are synthesized based on triethanolamine and fatty acids. In general, the synthesis ratio of triethanolamine and fatty acids, including US Pat. In addition, in order to satisfy both flexibility and water absorbency in the fabric softener using the surfactant, US Pat. No. 50,033, describes the ratio of stereoisomers based on unsaturated bonds of alkenyl groups, ie, oleic acid, in cis / trans trans) = 50/50 ~ 90/10 was used to adjust.

However, ester bonds introduced for the purpose of biodegradation have the problem of being hydrolyzed in the fabric softener products with time and eventually have the disadvantage of losing the function of the product in the distribution process. In addition, the flexibility and absorbency of fibrous softeners vary according to the cis / trans ratio of oleic acid in N-methyl, N, N-di- (C _{14-18 -acyloxy} ethyl) and N-hydroxyethyl ammonium methosulfate molecules. However, it was difficult to fundamentally overcome the limitations of high absorbency and low flexibility, which are basic characteristics of oleic acid.

In order to solve the problems of the prior art as described above, by optimizing the ratio of fatty acids and amines to synthesize mononitrogen quaternary cationic compounds optimizing the composition ratio of mono / di / tri alkyl group or alkenyl group in the molecule ester after fabrication of softener The present invention has been completed by developing a fiber softener composition which delays the hydrolysis of the bond and improves flexibility and water absorption.

Accordingly, an object of the present invention is to provide a fabric softener composition containing a mononitrogen quaternary cationic compound which not only improves flexibility and water absorption, but also significantly improves storage stability.

In order to achieve the above object, the present invention

Provided is a fabric softener composition containing a mononitrogen quaternary cationic compound represented by Formula 1 below:

[Formula 1]

In Chemical Formula 1,

R ₁ , R ₂ and R ₃ are each N-hydroxyethyl; Linear or branched alkyl groups having 12 to 22 carbon atoms; Linear or branched alkenyl groups having 12 to 22 carbon atoms; Or a mixture of these alkyl groups and alkenyl groups,

The content of mono-alkyl group or mono-alkenyl group in the molecule is 25-50% by weight, the content of di-alkyl group or di-alkenyl group is 35-60% by weight,

X is halogen, CH ₃ SO ₄ or C ₂ H ₆ SO ₄

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

The mononitrogen quaternary cationic compound represented by the formula (1) is generally trans-esterified triethanolamine and fatty acid in a small amount of catalyst or non-catalytic condition, and the resulting amine ester is halogen, CH ₃ SO ₄ or C ₂ Prepared through the process of quaternization using H ₆ SO ₄ , the molar ratio of triethanolamine / fatty acid to about 1/2 and the alkyl group or alkenyl group corresponding to R ₁ , R ₂ and R ₃ of Formula 1 The presence of two in the molecule is known to have an ideal effect.

However, the present inventors carry out the reaction at a molar ratio of triethanolamine / fatty acid at a ratio of 1 / 1.35 to 1 / 1.75, and analyze the content of the mono / di-alkyl group or alkenyl group of the compound molecule synthesized by this reaction, As a result, when the content of mono-alkyl group or mono-alkenyl group in the total molecule is 25 to 50% by weight, and the content of di-alkyl group or di-alkenyl group is 35 to 60% by weight, the flexibility, water absorption and excellent long-term It has been found to delay hydrolysis during storage and to be excellent in water dispersibility.

Fatty acids used in the present invention are fatty acids having 12 to 22 carbon atoms, preferably fatty acids having 16 to 18 carbon atoms, for example , stearic acid, oleic acid, palmitic acid, linoleic acid or mixtures thereof. In particular, the fatty acid is most preferably a mixture containing 10 to 40% by weight of stearic acid, 30 to 50% by weight of oleic acid and 10 to 60% by weight of palmitic acid. If a fatty acid having 12 or less carbon atoms or 22 or more carbon atoms is used, it is accompanied by a significant decrease in flexibility, which is the greatest role of the softening agent.

In the present invention, the ratio of triethanolamine and fatty acid is lower as the molar ratio of fatty acids increases the content of mono-alkyl or mono-alkenyl groups in the ratio of alkyl or alkenyl groups in the molecule, and relatively tri-alkyl or tri-alkenyl groups. Decreases. The molar ratio of triethanolamine / fatty acid used in the present invention has a ratio of 1 / 1.35 to 1 / 1.75, preferably 1 / 1.40 to 1 / 1.70. Lower molar ratios of fatty acids at molar ratios of triethanolamine / fatty acids of 1 / 1.35 or less result in lower flexibility, and higher molar ratios of fatty acids at molar ratios of 1 / 1.75 or higher reduce hydrolysis of the ester bonds, lower dispersion stability, and lower absorbency. May be accompanied.

The content of the mono / di / tri-alkyl group or the mono / di / tri-alkenyl group is related to the synthesis ratio according to the molar ratio of triethanolamine / fatty acid, but can be controlled in part according to the reaction temperature and the selection of the catalyst. The use ratio of mono / di-alkyl group or mono / di-alkenyl group in the molecule used is 25 to 50% by weight of the mono-alkyl group or the mono-alkenyl group in the whole molecule, and the content of the di-alkyl group or the di-alkenyl group. It is 35-60 weight%, Preferably, the content of a mono-alkyl group or a mono-alkenyl group is 30-50 weight%, and the content of a di-alkyl group or a di-alkenyl group is 45-60 weight% of all the molecules. When the content of the mono-alkyl or mono-alkenyl group is less than 25% by weight, the content of the di / tri-alkyl group or the di / tri-alkenyl group is relatively increased, the dispersibility is lowered, and the hydrolysis rate of the ester bond is increased, When the content of the mono-alkyl group or the mono-alkenyl group is more than 50% by weight, the flexibility is lowered. In addition, when the content of the tri-alkyl group or the tri-alkenyl group is 15% by weight or more, the water dispersibility is lowered and the hydrolysis rate of the ester bond is increased.

In addition, in the synthesis of the mono-nitride quaternary cationic compound represented by Formula 1, it may include a solvent such as mono-ethylene glycol, diethylene glycol, isopropyl alcohol, ethanol in order to improve reactivity, workability, usability, etc. have.

The mononitrogen quaternary cationic compound represented by Formula 1 is included in an amount of 1 to 30 parts by weight based on 100 parts by weight of the total fiber softener composition, and the compound is one or more of various cationic surfactants, that is, dialkyl dimethylammonium compounds. , Esteramide amine, dialkylimidazolinemethylsulfate cation and the like can be used. If the content exceeds 30% by weight there is a problem that the emulsion stability and freezing stability is poor.

The fabric softener composition of the present invention may further include a nonionic surfactant as an emulsifier, if necessary, in addition to the mononitrogen quaternary cationic compound represented by Formula 1, which is a cationic surfactant.

As the nonionic surfactant, polyoxyethylene alkyl ether, alkenyl ether or polyoxyethylene alkyl phenyl ether having 10 to 20 carbon atoms; Alkyl-hydroxy fatty acid esters having 10 to 20 carbon atoms; Sorbitan fatty acid alkyl esters and ethylene oxide adducts thereof, and polyoxyethylene alkyl, alkenylamides; Polyoxyethylene alkyl, alkenylamine; Glyceryl monoalkyl-alkenyl esters; Ethylene oxide adducts of hardened castor oil; Alkylamine oxides; Or amido propylamine oxide etc. can be used individually or in mixture of 2 or more types.

The nonionic surfactant is preferably included in 0.1 to 10% by weight based on 100% by weight of the compound of the present invention. When the content exceeds 10% by weight, the stability of the product is lowered, and as the content of the nonionic surfactant increases, there is a problem of inhibiting the softening effect by preventing the cationic compound of the present invention from being adsorbed on the garment.

In addition, the fabric softener composition of the present invention may further include a dispersion stabilizer as necessary.

The dispersion stabilizer may be a lower alcohol or glycol having 1 to 8 carbon atoms, higher alcohols having 12 to 20 carbon atoms, urea, magnesium chloride, sodium chloride, calcium chloride or sodium nitrate. In particular, ethanol, isopropyl alcohol, ethylene glycol, propylene glycol, hexylene glycol, trimethylpentanediol, cetyl alcohol, stearyl alcohol, magnesium chloride, sodium chloride, calcium chloride or sodium nitrate are preferably used.

The dispersion stabilizer is preferably included in an amount of 0.1 to 20% by weight based on 100% by weight of the compound of the present invention, when the content exceeds 20% by weight, the softening effect is lowered, which may cause excessive cost there is a problem.

In addition, the fabric softener composition of the present invention may further include additives such as fragrances, preservatives, fungicides, optical brighteners, pigments, antioxidants, or antifoaming agents generally used as additives of the fabric softener, the content of which is It is preferable to include 0.01 to 3% by weight in 100% by weight of the fabric softener composition so as not to affect the product stability.

Typically, the basic content of the net softener in the general-purpose product is 3 to 10% by weight, and most of the concentrated product is 10 to 30% by weight, but it is converted to the standard use concentration, which is softly treated to various fibers during rinsing after washing. In the case of general product, 6% of pure substance, 0.67 mL of pure substance of fabric softener is used per 1L of wash water.
