DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a detergency. The present invention relates to a high-concentration liquid cleaning composition having excellent foaming power. [Prior art and its problems] Most kitchen detergents currently mainly used for home use are liquid detergents. By the way, looking at the housing situation in Japan in recent years, it is a fact that it is not possible to take a large space in the kitchen part, and in the sink part, tableware etc. are arranged in a very narrow part. . How to effectively use this limited part is a problem for housewives and other people who often work in the kitchen. One of the solutions is to make the kitchen detergent used every day more compact. Placing large detergent bottles in very small spaces is extremely inefficient, and miniaturization of kitchen detergents has been a long-awaited theme. Surfactants mainly used in current kitchen detergents are:
Linear alkyl benzene sulfonate, lauryl sulfate,
Polyoxyethylene lauryl ether sulfate, α-olefin sulfonate, etc., and the surfactant concentration during washing is usually 25 to 35% by weight. Studies on increasing the concentration using these surfactants have been conducted for some time, and even when a delicate combination of various surfactants and a large amount of solubilizer are used, 40 to 45% by weight can be obtained. It is a limit.
In addition, those compacted in this way have high viscosity, are difficult to use, or have poor stability at low temperatures, and those that satisfy consumers with high concentration, ease of use, and stability are satisfactory. Not obtained. [Means for Solving the Problems] The present inventors have conducted intensive studies to solve the above-mentioned drawbacks. As a result, the present inventors have found that the surfactant base is a fatty acid diethanolamide and a fatty acid monoethanolamide / ethylene oxide adduct (hereinafter ethylene oxide is referred to as EO). The surfactant concentration is 70% by weight or more by combining a terpene hydrocarbon, an aliphatic lower alcohol and water within a certain range. The present invention was found to be excellent in detergency, stability, and low viscosity. That is, the present invention provides a high-concentration liquid detergent composition containing the following components A to D. (A) A mixture of fatty acid diethanolamide and fatty acid monoethanolamide EO adduct, in a weight ratio of 8: 2 to 5: 5
(B) Terpene hydrocarbon 2.5-7.5% by weight (C) Aliphatic lower alcohol 2.5-7.5% by weight (D) Water It constitutes the base of the activator, and a mixture of aliphatic diethanolamide and fatty acid monoethanolamide / EO adduct in a specific ratio is used. The alkyl group of these fatty acid alkanolamides preferably has 10 to 14 carbon atoms. If the alkyl group is 16 or more, the liquid cannot be maintained in the composition. The number of moles of EO addition of the fatty acid monoethanolamide EO adduct is preferably from 1 to 15. The component A is mixed in the composition at 70 to 90% by weight. If it is less than 70% by weight, the object of the present invention is to increase the concentration. 90% by weight
Above, stable transparent liquefaction becomes difficult. Representative of component A are coconut oil fatty acid diethanolamide, lauric acid ethanolamide, myristic acid diethanolamide, coconut oil fatty acid monoethanolamide (2EO),
Coconut fatty acid monoethanolamide (5EO), coconut fatty acid monoethanolamide (10EO), lauric acid monoethanolamide (2EO), lauric acid monoethanolamide (5EO), lauric acid monoethanolamide (10E)
O), myristic acid monoethanolamide (5EO), myristic acid monoethanolamide (10EO), and myristic acid monoethanolamide (15EO). The terpene hydrocarbon of the B component used in the present invention is preferably a monoterpene hydrocarbon, and functions as a solubilizer synergistically with the C and D components. Preferably,
Examples include limonene, pinene, and myrcene. The amount of component B in the composition is preferably 2.5 to 7.5% by weight, preferably 2.5% by weight.
Under the following conditions, it is difficult to maintain a transparent liquefaction, and at 7.5% by weight or more, the odor may be too strong when used to make it unpleasant. The most preferred aliphatic lower alcohol of the component C is ethanol, which works as a solubilizer synergistically with the components B and D. The amount of the component C in the composition is 2.5 to 7.5% by weight.
If it is less than 2.5%, it will be difficult to maintain transparent liquefaction, and if it is more than 7.5%, the odor during use may be unpleasant. The water of the component C is preferably used in the composition in the range of 5 to 15% by weight. Even if the amount is less than 5% by weight or more than 15% by weight, the transparent liquefaction cannot be maintained or the stability at low temperature becomes poor. Or As another invention of the present invention, there is a liquid detergent composition further comprising an inorganic acid and / or an organic acid in addition to the above components. The inorganic and organic acids of the fifth component include:
Hydrochloric acid, sulfuric acid, phosphoric acid, citric acid, tartaric acid, malic acid, oxalic acid, etc. are used, and the compounding amount varies depending on the type and amount of the base fatty acid alkanolamide, but 0.1 to
5% by weight can be used. If these acids are not used, slight roughening will be observed during use, but by adding the acids, a milder, highly concentrated kitchen detergent can be obtained. If necessary, a solubilizer such as glycerin, p-toluenesulfonic acid, and urea, a foaming enhancer, a fragrance, and a colorant may be added to the high-concentration liquid detergent of the present invention. In addition, other anionic surfactants, cationic surfactants, amphoteric surfactants,
A nonionic surfactant may be added within a range that does not inhibit the object of the present invention. These include, for example, fatty acid soaps, higher alcohol sulfates, polyoxyethylene higher alcohol phosphates and salts thereof, polyoxy higher fatty acid phosphates and salts thereof,
Sulfonated higher fatty acid alcohol ester salt, higher alcohol sulfosuccinate, isethionic acid higher fatty acid ester salt, N-acyl-N-methyltaurine salt, acylsarcosine salt, N-acyl-N-methyl-β-alanine salt, acylglutamic acid Salt, α-sulfo higher alcohol acetate, polyoxyethylene higher fatty acid monoethanolamide phosphate, amine oxide, alkyl dimethyl betaine, 2-alkyl-N-carboxyalkyl-N-hydroxyethyl imidazolinium betaine, fatty acid amidopyro Examples include, but are not limited to, pilldimethylaminoacetate betaine. [Examples] As shown in Examples 1 to 7 in Table 1, liquid detergent compositions having different formulations were prepared, and the state of the compositions and the dish washing test were performed. Table 2 shows Comparative Examples 1 to 5 performed similarly. (Evaluation of condition) ○: Transparent liquid △: Translucent or paste-like ×: Cloudy or solid (Dish washing test method) Mix soybean oil and refined tallow in a ratio of 6: 4 and colorize with 0.1% oil blue 2.0 ml of artificial soil as specified dish (White meat dish with a diameter of 20 cm) and spread it evenly on the dish with your fingertips. 0.15% concentration
Use 1500ml (30 ° C) sample aqueous solution (30cm diameter x
After removing the foam to a depth of 14cm), tap water at 30 ° C 5
Drop 00 ml from 50 cm above the surface of the sample aqueous solution in the tub, and make bubbles on the water surface in the tub. Put the soiled dishes in the tub one by one, and put a cotton cloth (30cm x 30cm)
Rub the front and back of the dish in a circular motion to remove any dirt. At this time, be careful not to create new bubbles on the liquid surface in the tub. Wash the dishes in this way, and evaluate the scrubbing performance of the sample with the number of dishes that can be washed until the foam created first disappears from the liquid level in the trough. In addition, those in which palmitic acid diethanolamide was used instead of coconut oil fatty acid diethanolamide in Example 1 and those in which palmitic acid monoethanolamide (5EO) was used instead of coconut oil fatty acid monoethanolamide (5EO) were used. All became solid. [Example 8] Coconut fatty acid diethanolamide 49% Lauric acid diethanolamide 4% Lauric acid monoethanolamide (10EO) 21% d-pinene 5% Ethanol 5% Polyoxyethylene (2) sodium laurin ether sulfate 5% α- Sodium olefin sulfonate 5% Methyl paraben 0.1% Citric acid 1.0% Water 8.9% [Example 9] Coconut oil fatty acid diethanolamide 46% Myristate diethanolamide 3% Coconut oil fatty acid monoethanolamide (2EO) 21% d-limonene 6% Ethanol 4% Sodium linear alkylbenzene sulfonate 10% Methyl paraben 0.1% Hydrochloric acid 0.2% Water 9.7% When the high concentration liquid detergents of Examples 8 and 9 were used in the kitchen at home, a general commercial kitchen detergent (A company product) , Surfactant concentration 27%) Showed the same detergency and less rough hands. Examples 8 and 9
When citric acid and hydrochloric acid were removed from Comparative Examples 6 to 7 and used in the same manner, the washing power was the same, but slight roughening was observed. [Effect of the Invention] The liquid detergent composition of the present invention is a high-concentration liquid detergent composition having a very high surfactant concentration of 70% by weight or more, compact and excellent in detergency. Therefore, it has the same detergency as less than half the amount of ordinary kitchen detergents, so it requires only small bolts, does not take up space in the kitchen, and saves storage space and freight during the distribution process.
