Description

Fabric softener composition {FABRIC SOFTENER COMPOSITION}

The present invention relates to a fabric softener composition, and more particularly, it is excellent in the uniform adhesiveness effect of clothing, not only excellent in flexibility, antistatic effect and water absorption, but also in storage stability, water dispersibility, and biodegradation effect. An improved fabric softener composition is disclosed.

Cationic dialkyldimethylammonium salts (JAOCS 61, 367 (1984), and 65 (10), 1682 (1988)), reported by the American Petrochemical Society, have long been used as main components of general fabric softeners. In recent years, the dialkyldimethylammonium salt has a low biodegradability, and the amount of dialkyldimethylammonium salt is decreasing, and research and application for introducing a group having a functional group capable of decomposing into an alkyl group, such as an ester or an amide, into an molecule have been actively conducted.

The fiber softener comprising a group having a functional group which can be decomposed as described above may be a cationic surfactant of amidoamine type quaternary ammonium salt, quaternary ammonium salt of amidoesteramine, imidazoline, and imidazoline ester type. Usually used a lot. As examples of these, Japanese Patent Application Laid-Open No. Hei 6-345704 discloses an amidoamine compound and a softening agent composition, and Japanese Patent Application Laid-Open Publication Hei 6-336466 uses an amidoesteramine compound and a softening agent composition. In 257372, a softening agent composition containing an imidazoline ester has been described. Japanese Unexamined Patent Application Publication No. Hei 2-1479 has described a compound for conditioning containing imidazoline. The cationic surfactants have improved biodegradability compared to cationic dialkyldimethylammonium salts, but have not been improved to a satisfactory level.

Recently, when an alkyl group, which is a lipophilic moiety in a cationic surfactant molecule, contains a functional group that is easily decomposed, such as an ester group, its biodegradability is the aforementioned conventional dimethyldialkyl ammonium chloride, amide quaternary ammonium salt, and imidazoline It has been reported to be very good compared to cationic surfactants (Tenside Surfactant Detergent, 1993, 30, 186-191). Accordingly, various derivatives of quaternary ammonium salts having ester groups in the molecule have been developed and commercialized. As a representative example of commercialization, WO 94/07978 discloses a softener and a hair protector using a quaternary cationic surfactant derived from triethanolamine, and WO 93/23510 discloses two hydrophobic groups. A concentrated fibrous softener and a biodegradable fibrous softener composition using a cationic surfactant having an ester bond are disclosed. International Publication No. 92/15745 discloses an imidazoline or imidazoline ester type fatty alcohol ethoxylate. Disclosed is a concentrated fabric softener composition. In addition, International Patent Publication No. 94/14935 discloses a concentrated fiber softener dispersant composition comprising a quaternary ammonium compound prepared from triethanolamine and a fatty acid, and International Patent Publication No. 94/13772 is a fourth-class having an ester group in a molecule. A highly concentrated fabric softener composition using a small amount of an ammonium compound and a nonionic dispersant is disclosed.

The quaternary ammonium salts containing ester groups in the molecule have low dispersibility in water, and in order to maintain product stability for a long time, a large amount of compounds such as glycerin, lower alcohols, and nonionic dispersants are used. As a result, there is a problem that the basic performance inherent to the quaternary ammonium salt is lowered.

Japanese Patent Application Laid-Open Nos. Hei 3-295855, Hei 4-208964, Hei 4-267468, Hei 4-28023, and Hei 4-6984 have amido ester tertiary amines and quaternary salts with excellent water dispersibility. A fiber softener having a main component thereof is disclosed, and the fiber softeners have a problem of poor storage stability at high temperature.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a fabric softener composition having excellent flexibility, antistatic effect, and absorbency excellent in the uniform adhesion effect of the clothing.

Another object of the present invention is to provide a fabric softener composition with markedly improved storage stability, water dispersibility, and biodegradation effect.

The fabric softener composition was prepared using amido ammonium salt having a good uniform adhesiveness effect of clothing, which is excellent in flexibility, antistatic effect and water absorption, and at the same time, water dispersibility and biodegradation effect are remarkably improved. After confirming this, the present invention was completed.

The fabric softener composition of the present invention is characterized in that it comprises an amido ammonium salt represented by the formula (1) having an amide group and a hydroxyl group in the molecule.

If the carbon number exceeds 21, the clothes may have a soft or excessive softening effect. There is a problem.

Amido ammonium salt represented by the formula (1) is prepared by the method of Scheme 1 to react the fatty acid and amine, and then tertiated using a tertiary agent, and then quaternized with dimethyl sulfate or alkyl halide.

n is an integer of 2-6.

Amido ammonium salt represented by the formula (1) is preferably included 1 to 30 parts by weight based on 100 parts by weight of the fabric softener composition. If the content is less than 1 part by weight, it may not satisfy the softening effect or the antistatic effect of various clothes, and if it exceeds 30 parts by weight, there is a problem in that the emulsion stability and freezing stability are poor.
