Description

Dishwashing Detergent Composition

The present invention relates to a dish detergent composition excellent in deodorizing effect. More specifically, the present invention contains at least one organic acid and at least one mint oil, and has a deodorant effect on the mercaptan odor and also contains an alkaline agent used as a pH adjuster, and additionally fungicides and flavors, The present invention relates to a dishwashing detergent composition having an excellent effect of deodorizing the odor generated from food waste and sewage, especially when washing dishes with hot water, and sterilizing microorganisms, which are one of the causes of odor.

There are many kinds of bacteria and yeast in the cutting boards and dish towels used in the kitchen, causing odor, and skin eczema is caused by frequent washing dishes and food debris on dishes. In particular, it is difficult to remove odors such as fishy (amine odor) and kimchi (mercaptan odor) from food, water, etc. Odor substances containing ammonia, amines, mercaptans, etc. generate odors. Conventionally, only detergents and disinfectants are used, or sterilization and disinfectants are separately used to clean and sterilize. In particular, odors are simply removed by circulating the air in the room, or a method using a special deodorant that is currently released in Japan. I use it.

Prior patent documents JP 92-298513 and JP 90-217064 describe general deodorant compositions using green tea extracts and polyols, and JP 90-297239 discloses deodorant and bactericides containing limonene and benzalkonium fluoride. JP 89-186267 describes sterilization and deodorant using chlorine compounds and alcohols. US 5260053 and JP 09103473 also describe deodorants using a combination of essence oils, JP 08281042 describes carbonized bamboo powders, and US 4906462 describes deodorants using phosphoric acid and its derivatives.

General deodorant preparations mainly use extracts derived from ethanol, green tea, bamboo, etc. as deodorants, or compounds such as p-dichlorobenzene, chlorine compounds (laxes) and benzalkonium chloride. I use it. Conventional dish detergents have only a function of cleaning or contain a fungicide and have only a sterilizing power so there is little effect on deodorization. In addition, if the deodorant used in the existing plant extracts contain enough content to have a deodorant effect in the dish detergent, the price of the extract is expensive and difficult to apply to dish detergent and affect the discoloration in the dish detergent. Also, compounds such as p-dichlorobenzene, chlorine compounds (laxes) and benzalkonium chloride, such as benzalkonium chloride, can be used as dishwashing agents with anionic surfactants. It may not function as a detergent or cause severe irritation to the skin.

Accordingly, the present inventors have conducted numerous studies and experiments to improve the problems of the prior art dish detergent, the dish detergent composition containing a specific organic acid and a specific mint oil in a specific blending ratio occurs in the kitchen. Food waste on cutting boards, dishcloths, and utensils, and other odorous substances containing ammonia, amines, mercaptans, etc. In addition to showing an excellent deodorizing power, it was found that the washing power, which is the main function of the kitchen detergent, was also excellent and completed the present invention.

The present invention contains 0.5 to 20% by weight of at least one organic acid selected from citric acid, malic acid, succinic acid, tartaric acid, sorbic acid, ascorbic acid, lactic acid and gluconic acid, eucalyptol, thymol, eugenol, methyl salicylate, menthol It relates to a kitchen detergent composition containing 0.005 to 5% by weight of at least one mint oil selected from among menthol, bammint and herbmint and having a pH of 4 to 8.

Organic acid which is a deodorant component used in the present invention serves to remove fishy smell that is the most odor that occurs in the kitchen. As a suitable organic acid, at least one selected from citric acid, malic acid, succinic acid, tartaric acid, sorbic acid, ascorbic acid, ascorbic acid, lactic acid and gluconic acid is used, and their chemical formulas are as follows.

In addition, the mint oil in the present invention is eucalyptol (eucalyptol), thymol (thymol), eugenol (eugenol), methyl salicylate (methyl salicylate), menthol (menthol), menthol (menthone), a mixture of mint oil Use at least one selected from balm mint and herb mint. Representative chemical structural formula of mint oil is as follows.

In the detergent composition of the present invention, the pH decrease occurs as the content of the organic acid increases. To solve this problem, an alkaline agent is used as a neutralizing agent. Suitable alkaline agents include one or more selected from sodium carbonate, sodium hydroxide, potassium hydroxide, triethanolamine, diethanolamine, and monoethanolamine. These alkalizing agents do not affect the organic acid exhibiting a deodorizing effect even when the pH is neutralized, and in particular, gives a synergistic effect to the deodorizing function against mercaptan odor. In addition, the use of alcohol-based solvents such as ethanol, isopropanol, isobutanol, propylene glycol, and ethylene glycol as viscosity modifiers shows synergistic and bactericidal effects against deodorization, particularly for mercaptans, among odor sources generated in sinks and drains. The viscosity lowering effect is also shown for the viscosity increase as the content is increased.

Detergent composition of the present invention is also deodorized in removing the cause of odor caused by bacteria even by adding fungicides such as triclosan, thiabendazole, thiram, trichlorocarbanilide, etc. May help to synergistic effects. In particular, the use of a deodorant made of metal ions such as zinc ricinoleate may help to increase the deodorant effect.

In the detergent composition of the present invention, the pH decrease occurs as the content of the organic acid used for the purpose of increasing the deodorant effect increases, and the kitchen detergent is a substance which is in direct contact with the skin. That is, the neutralizing agent is adjusted to pH 4 to 8 by containing at least one of sodium carbonate, sodium hydroxide, potassium hydroxide, triethanolamine, diethanolamine, and monoethanolamine. The detergent composition according to the invention has a pH of 4 to 8, preferably 5 to 7 at room temperature.

Hereinafter, although this invention is demonstrated based on an experiment example and an Example, the technical scope of this invention is not limited to these.

Experimental Example 1. Deodorizing force test method

Each deodorant shown in Table 1 was put in a sealed container, and then, the same amount of odor source (3 types) was put in each of them, and after a certain time, the residual amount of odor that had not been deodorized was sucked into the detection tube to measure the concentration of residual gas (Gastec). Detector, use a detector tube).

TABLE 1

As shown in Table 1, when a raw material having deodorizing power was diluted (to 100) with water or ethanol or used as an undiluted stock solution, the mixture of organic acids showed an excellent effect on the deodorization of ammonia and amine. Mint oils (Comparative Example 7-9), such as eucalyptol, menthol and bammint, exhibit excellent deodorizing power for mercaptans. In addition, the addition of ethanol amine to the organic acid increases the deodorizing power to mercaptan while maintaining the deodorizing power to ammonia and amine. The addition of ethanol and fungicides (Comparative Example 11) also shows synergistic effects on deodorizing and bactericidal properties.

TABLE 4

As shown in Examples 1 to 8 of Table 4, when the organic acid used in the present invention is used as an active ingredient of kitchen detergents sold in the general market, excellent odors, especially against alkaline odors such as ammonia and amines When the alkaline agent is used, the deodorizing power on the alkali system is not affected by the role of giving the deodorizing auxiliary effect to the odor of the mercurtan while adjusting the pH. In addition, the use of an alcoholic solvent such as ethanol in the composition of the present invention can control the degree of auxiliary effect on the deodorizing power and the degree of dishwashing agent affects the improvement of usability. In addition, the addition of fungicides increases the bactericidal power against bacteria, thereby aiding in the removal of odors generated from bacteria, and also affecting kitchen hygiene. In Example 4, as shown in Example 5, the deodorizing power was lowered when the content of citric acid in the detergent was 0.5 parts by weight or less, and when the content of citric acid was 20 parts by weight or more, the viscosity of the pH regulator was increased and The content is increased excessively and the detergency and foaming power are lowered.

TABLE 5

In Example 9 shown in Table 5, when mint oils, such as organic acids in detergents, were used as shown in Example 16, the deodorizing effect of the mercaptan was particularly excellent, and the mint oil used was one or more. Even when mixed, the deodorant reaction to odor is constantly acted on by the specific structure of mint oil itself, so the effect of single or mixed use is excellent without any difference. When the content of mint oil is 0.005% by weight or less as in Example 9, the deodorizing power is lowered. When the content of oil is 5% by weight or more, the cleaning power, foaming power, and phase stability of the cleaning agent are lowered due to the specificity of the oil. Excessive odor can be given and may cause disgust.

(5) Practical deodorant effect experiment

Thirty housewives between 20 and 40 years old were selected and the kitchen detergents of Example 16 and Comparative Example 13 were distributed, and the two detergents were used for dish washing for 15 days. Evaluated.
