Description

Polypropylene oxide addition type cationic surfactant, preparation method thereof and detergent composition using the same

The present invention relates to a polymeric cationic surfactant using polypropylene oxide as a hydrophobic group of a surfactant, a method for preparing the same, and a fabric softener composition comprising the same. More specifically, the present invention provides a softening and antistatic property by adsorbing to a fiber. The present invention relates to a cationic surfactant, a method of preparing the same, and a fabric softener composition including the same, which has a deodorizing power and can maintain a transparent appearance of a product even with a small amount of emulsifier in the manufacture of the fabric softener, and imparts high foam suppression power when rinsing.

Cationic surfactants are used as the main component of the fabric softener because they have the effect of general surfactant and adsorbed to the fibers by the cation in the aqueous solution to show the softening and antistatic effect.

Dimethyl dialkyl ammonium chloride (dimethyl dialkyl ammonium chloride) was widely used as a representative cationic surfactant in the early stage of development of cationic surfactants, but its use is gradually decreasing due to its low biodegradability. Accordingly, studies have been actively conducted to introduce substituents having functional groups that can be decomposed into an alkyl group, such as esters and amides, into the molecule, and are now quaternary ammonium salts of amidoamines, quaternary ammonium salts of amidoesteramines, Cationic surfactants based on dazoline and imidazoline esters have been developed and widely used.

For example, Japanese Unexamined Patent Publication No. 6-345704 describes a method for preparing an amidoamine compound and a cationic surfactant using the same, and a method of using the same as a fabric softener. It describes a method for producing an amine ester amine compound and cationic surfactants using the same and a method of using the same as a fabric softener. In addition, Japanese Unexamined Patent Publication No. 4-257372 discloses a method for preparing imidazoline ester and a softener composition, and Japanese Patent Laid-Open No. 2-1479 discloses a method for preparing imidazoline and conditioning for the same. Compounds are disclosed.

In addition, International Patent Publication No. 94-07978 discloses a method for preparing a fabric softener and a hair care product using a quaternized cationic surfactant derived from triethanolamine. International Patent Publication No. 93-23510 Discloses a method for preparing a concentrated fiber softener and a biodegradable fiber softener composition using a cationic surfactant having ester bonds to two hydrophobic groups, and International Patent Publication No. 92-15745 discloses imidazolines. Or a method for producing a concentrated fiber softener composition using a linear fatty alcohol ethoxylate, polydialkylsiloxane and the like to the imidazoline ester has been disclosed.

However, the conventional cationic surfactants include two C ₁₆ to C ₁₈ alkyl groups in one molecule in order to increase the softening effect. In this case, the solubility in water is very low. In use, the appearance is opaque. On the other hand, when containing a single alkyl group may have a transparent appearance, but the softening effect is lowered and a large amount of foam avoided in the fabric softener is generated.

In order to secure a transparent phase, an oleyl group may be introduced into an alkyl group which is a hydrophobic part of a cationic surfactant. However, discoloration and odor occur during manufacturing and transparency is not secured when dispersed in water.

In addition, U.S. Patent No. 5,280,481 and U.S. Patent No. 5,282,983 disclose patents for preparing cationic surfactants having an amide group and an ester group in a molecule, and in this case, after the amidation and esterification reaction of fatty acids and amines, There is a large amount of the reaction fatty acid, there is a large amount of unreacted amine according to the temperature conditions or a large amount of synthetic amine of amide-esteramine according to the molar ratio of the quaternizing agent such as alkyl halide and dimethyl sulfate. Unreacted materials that do not have the form of quaternary ammonium salts are inconvenient to undergo a process such as purification, and even if purified, they are not completely removed, resulting in poor stability, and transparency in dispersing in water due to the presence of these unreacted materials. There is a disadvantage that is not secured.

In addition, in order to secure a transparent phase, asymmetric two alkyl chains of cationic surfactants or Gemini type cationic surfactants have been studied in a form similar to the previous studies, but the manufacturing process thereof is complicated and a large amount of unreacted substances are present. There is a problem of generating a large amount of bubbles in the aqueous solution.

Therefore, the inventors of the present invention utilize a polypropylene oxide as a hydrophobic group of a surfactant, and thus have excellent flexibility, antistatic power, deodorizing power, transparency, a transparent phase, and a novel material capable of suppressing bubble generation, which is a major problem of existing cationic surfactants. To develop a polymeric cationic surfactant.

The present invention has been made to solve the above problems, the object of the present invention is to adsorb on the fiber to give softness and antistatic power and has a deodorizing power and to produce a transparent appearance of the product with only a small amount of emulsifier in the fabric softener The present invention provides a novel cationic surfactant, a method for preparing the same, and a fabric softener composition containing the same, which can be maintained and impart high foam suppression force when rinsing.

To evaluate the flexibility, 4 towels were washed with the highest so-called (approximately 43L water supply, spark 43g as a laundry detergent) of the top-loading washing machine (LG tungsten 10kg, WF-CK105A). Progress was made using about 29 g (using 0.67 g / L) of each fabric softener composition. Afterwards, sensory evaluation was conducted on 10 experienced panelists. When washing with only a general detergent to one point, when using Comparative Example 1 in a general washing machine to 3.7 points to let the panel to recognize the reference towel, the softness was evaluated. The results are shown in Tables 7 to 8 below.

According to Tables 7 to 8, as the number of moles of propylene oxide added to TEAQ increases, the softening effect increases, and TEAQ 140 has a similar softening power to that of conventional cationic surfactants, EQ and IMQ.

Experimental Example 3 Evaluation of Bubble Suppression

The bubble suppressing force in the rinsing step was evaluated for the fabric softener compositions of Examples 4-10 and Comparative Examples 1-6. The bubble inhibition was measured by percentage of the surface area of the bubble in the four stages of initial water supply, additional water supply, stop after stirring, and drainage.

According to Tables 9 to 10, as the number of moles of propylene oxide of TEAQ increases, the bubble suppression force is improved, and as the amount thereof is used, the bubble suppression force is improved. In the case of a conventional cationic surfactant, a large amount of bubbles are not generated, but when unsaturated unsaturated acids or emulsifiers are used to improve transparency, the generation of bubbles is increased. In addition, when using a silicone-based antifoaming agent to further suppress such bubbles may cause a technical problem that becomes opaque again.

Since the polymeric cationic surfactant of the present invention has excellent antifoaming properties, bubbles may be generated temporarily in the water supply process or the stirring step even in Examples 6 to 8, but because all the bubbles are destroyed within a few seconds when stopped, the user You can't actually see bubbles.

The deodorizing power evaluation of TEAQ of the present invention was measured and compared.

3 g of TEAQ was added to the saelai in the desiccator, and the deodorant power was compared by comparing the concentration of the deodorant agent 24 hours after the injection of the deodorant. Samples used as deodorant were TEAQ PO80, TEAQ PO140 and beta-cyclodextrin and charcoal which are widely used as deodorant as comparative samples. The deodorant used was compared using ammonia, hydrogen sulfide, methyl mercaptan, trimethylamine, and the initial concentration was carried out at about 150 ppm ammonia, about 80 ppm hydrogen sulfide, about 15 ppm methylmercaptan, and about 80 ppm trimethylamine.

The removal rate of the above-described deodorant was measured and shown in Table 11 below.

TABLE 11

TEAQ PO80 TEAQ PO140 Beta-CD charcoal ammonia 96.7% 97.5% 67.4% 96.7% Hydrogen sulfide 6.9% 7.2% 11.8% 100.0% Methyl mercaptan 15.4% 18.0% 8.3% 100.0% Trimethylamine 73.7% 92.3% 56.0% 95.7%

In Table 11, TEAQ shows excellent deodorizing power in ammonia and trimethylamine, and deodorizing power in comparison with charcoal shows excellent deodorizing power even for inferior or beta-cyclodextrin.

The cationic polymer surfactant of the present invention can be used in general household detergents such as laundry detergents, shampoos, rinses, dish detergents, body cleansers, and cleansing cosmetics, similarly to the case of the fabric softener composition.
