Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fabric softener composition for imparting flexibility to fibers, clothing, hair, etc., and in particular, a fabric softener composition that is less likely to stain laundry items, and Discoloration occurs during long-term storage.

This invention relates to a colored softener composition that exhibits less fading and excellent stability.

Conventional technology Fabric softeners are used to add softness to clothing.

Usually, the main component is a di-long-chain alkyl di-short-chain alkyl quaternary ammonium salt, a di-long chain quaternary imidazolinium salt, etc., and is used in the form of a dispersion in an aqueous medium. In such softeners, pigments such as dyes and pigments are often added for the purpose of imparting or enhancing aesthetic appearance.

However, fabric softeners that contain dyes have the problem of fading or fading of color due to the effects of heat and light during long-term storage, and when fabric softeners are treated, one dye may be adsorbed to the fibers. He had a problem with dyeing, which caused him to dye his clothes. Particularly when selling in a product form such as a transparent bottle, dyeing of clothing due to fabric softener and discoloration and fading during storage have a significant impact on product value.

Therefore, many studies have been made on coloring agents for softener compositions, but it is difficult to solve the above problems and still color the compositions in beautiful colors.
The blue or green coloring was particularly interesting.

The object of the present invention is to provide a colored fabric softener composition that does not stain clothes etc. during use, does not change color or fade during storage, and has excellent long-term stability.

The softener composition of the present invention is characterized by containing the following components (A) and (B).

(A) One or a mixture of two or more quaternary ammonium salts represented by the following general formula (1).

(In the formula, R, R2:, alkyl group or alkenyl group with R prime number of 8 to 24 R3, R,: methyl group, ethyl group, hydroxyethyl group, hydroxypropyl group, polyoxypropyne group or polyoxypropylene group) X-: Anion) (B) A phthalocyanine dye having a sulfonic acid group and a reactive dye having a triazine ring.

The present invention will be explained in more detail below.

Component (A) of the present invention is a quaternary ammonium salt type cationic surfactant, and is a cationic surfactant of the above general formula (I), a halogen atom, an alkyl sulfate group having 1 to 2 carbon atoms, or a cationic surfactant having 2 to 6 carbon atoms. carboxylic acid groups, phosphoric acid groups, etc. Specific examples of quaternary ammonium salts include the following, which may be used alone or as a mixture of two or more.

・Dilauryldimethylammonium chloride ・Civalmityldimethylammonium chloride ・Di(hydrogenated tallow alkyl)dimethylammonium chloride ・Distearyldimethylammonium chloride ・Dioleyldimethylammonium chloride ・Distearylmethylpolyoxyethylene (average degree of polymerization 1 to 10 moles) ) The quaternary ammonium salt compound of ammonium chloride di(palm oil alkyl) dimethylammonium chloride (A) component is preferably blended in the softener composition in an amount of 0.1 to 50% by weight, more preferably 2 to 15% by weight. % by weight is added.

In the present invention, as the colorant of component (B), a phthalocyanine dye having a sulfonic acid group and a reactive dye having a triazine ring is used. This dye is
When blended into a softener composition containing a grade ammonium salt, it causes less dyeing and has extremely good stability against heat and light during storage compared to other dyes. This storage stability is exhibited whether the long chain group of the quaternary ammonium salt is saturated (alkyl) or unsaturated (alkenyl). In conventionally used dyes, the stability deteriorates significantly, especially when the long chain group is unsaturated.

As a specific example of the phthalocyanine-based reactive dye of component (B), the color index name (Colo
ur Index Number), Reactive Blue 41
), Reactive Blue 15 (Reactive B
lue 15), Reactive Green 5 (Rea
active Green 5), etc.

The phthalocyanine-based reactive dye as component (B) is preferably blended in the softener composition in an amount of 10-6 to 1% by weight,
More preferably, it is 10-s to 10-2% by weight.

When the softener composition of the present invention is used as an aqueous liquid or paste softener, hydrotropes such as ethylene glycol, propylene glycol, glycerin, and ethanol, and polyoxyethylene (i5=10 to 70) Alkyl (c*-02) phenyl ether, polyoxyethylene (p=lo~70) alkyl or alkenyl (C1,,□) ether, polyoxyethylene (i5.=10~70) alkyl or alkenyl (CX. -2□) 1 to 10% by weight of a nonionic surfactant such as amine can be blended. Alternatively, viscosity modifiers such as inorganic electrolytes, hand feel improvers such as silicones, anionic polymers, hydrocarbons, and cellulose derivatives, other disinfectants, fragrances, and the like may be appropriately blended.

According to the present invention, a composition is prepared by blending a phthalocyanine dye having a sulfonic acid group and a reactive dye having a triazine ring with a quaternary ammonium salt type cationic surfactant. Due to the coloring, it does not dye the objects to be treated such as clothing when used, and the composition does not change color or fade due to the influence of light or heat during storage, and has excellent long-term storage stability. A drug composition is obtained.

Example 1 Components other than dioleyldimethylammonium chloride and isopropyl alcohol in the following composition were dissolved in water, and while heating this to 45°C or higher and stirring, a mixture of dioleyldimethylammonium chloride and isopropyl alcohol was added dropwise. After dispersing it evenly,
The mixture was slowly cooled to 5° C. to prepare softener compositions containing various dyes.

Table-1: Composition of softener composition Isopropyl alcohol Ethylene glycol Salt Flavor Various dyes (listed in Table-2) 1.5wt% 3wt% 0.01wt% 0.2wt% 0.003wt% 100wt% Contains various dyes For each softener composition, the dyeability and stability against heat and light were evaluated using the following evaluation method.
The results are shown in Table 2 below along with the dyes used.

(1) Dyeability test A multi-woven fabric made of nine types of fibers: polyester, silk, acrylic, rayon, wool, acetate, vinylon, nylon, and silk is used.

A multi-woven fabric was made to have a squeezing rate of 200%, 10 g of the above softener composition (aqueous dispersion) was dropped onto all the fibers of the fabric, and after being left for 3 hours, it was rinsed with tap water for 3 minutes and then dried. dry. Then, the dyeing on the dried cloth is visually observed, and the degree of dyeing on the clothing is evaluated according to the following criteria.

0: Almost no staining Δ: Slight staining ×: Dyeing observed (2) Stability against heat (discoloration/fading) test Place the softener composition in a glass bottle and seal it and use it as a sample. This sample is placed in a constant temperature bath at 80°C, and after 40 hours, the color tone is compared with that of the sample stored at 5°C, and the stability against heat is evaluated using the following criteria.

O: No discoloration/fading is observed 0: Slight discoloration/fading Δ: Slight discoloration/fading ×: Discoloration/fading is clearly observed (3) Stability against light (discoloration/fading) Test A transparent glass bottle filled and sealed in the same manner as above was used as a sample, and this sample was irradiated with ultraviolet carbon arc for 4 hours. Based on the same criteria as in (2) above, it was compared with a stored item that was not irradiated with ultraviolet carbon arc. Compare and evaluate the color tone.

(The following is a blank space) Example 2 A softener composition was prepared using dicured beef tallow alkyldimethylammonium chloride in place of the dioleyldimethylammonium chloride used in Example 1. At this time, dyes shown in Table 3 below were blended, and dyeability and storage stability were evaluated in the same manner as in Example 1.

By using , the stability is improved for both saturated and unsaturated alkyl groups (No. 8).

As shown in Table 3, when the alkyl group of the quaternary ammonium salt to be blended is a saturated alkyl group, Direct B
The photostability (number 7) when using direct dyes such as lue 199 is the same as that for unsaturated alkenyl groups (Table 2).
Although it is slightly better than No. 1), it is still insufficient.
