TW483933B - Liquid detergent composition - Google Patents

Abstract

A liquid detergent composition containing a surfactant in an amount ranging from 25 to 50% by weight. Wherein the liquid detergent composition further contains (a) an aromatic carboxylic acid represented by formula (I): wherein X, Y and Z represent, independently of each other, one of the groups selected from the group consisting of hydrogen, methyl, ethyl and hydroxy groups; and (b) a degree of dissociation of the above carboxylic acid ranges from 5 to 95%. The liquid detergent composition does not cause any feeling of being slimy when used in cleansing and any feeling of the detergent remaining on hands after use. The liquid detergent composition can be completely washed away with a little amount of water and is superior in handling and economy.

Description

483933 V. Description of the invention α) [Technical Field] The present invention relates to a dense type of detergent useful as a liquid detergent for hard surfaces (including kitchen detergents) or a detergent for body or hair The composition provides a detergent composition which exhibits excellent hand feeling (touch of the hand) at the time of washing and shows good low-temperature stability. [Background Art] Recently, in liquid detergent compositions led by kitchen detergents, dense liquid detergent compositions have begun to become mainstream, and consumers and distributors have benefited more. So far, regarding the surfactants incorporated in the detergent composition, based on the viewpoint of excellent cleaning performance, research and development on the composition centering on anionic surfactants has been carried out, and in the dense type In the case of a detergent composition, since the ingredients are blended at a high concentration, a slippery (greasy) appearance during washing is liable to occur. If there is a greasy feeling during washing, it will easily fall off during use, which is not only difficult to wash, but also leaves a residual feeling on the skin of the hands after washing, and a large amount of water is required for rinsing after washing. It is a problem in terms of workability and economy. So far, there have been proposed patents (Japanese Patent Laid-Open Publication No. 2-609999) on a detergent composition for improving the feel (Japanese Patent Laid-Open No. 2-6099). The low-temperature stability of high-concentration systems, and the lack of cleaning power caused by the large amount of nonionic surfactants and the reduction of anionic surfactants are the problems. Therefore, in recent years, it has been highly desired to develop a dense composition which exhibits an excellent feel regardless of the type of the detergent.

A group of the composition), (b) the acid dissociation degree of the aromatic carboxylic acid is in a range of 5 to 95%. [Best Mode for Implementing the Invention] In the detergent composition of the present invention, a conventionally used anionic surfactant and non-ionic interface activity can be optionally combined within a range that does not impair the effect of the present invention. Agents, amphoteric surfactants, and other compounds with interfacial activity are used. The surfactant is used in a total amount of 25 to 50 wt% of the detergent composition. Females are preferred surfactants, and examples include anionic surfactants, non-ionic surfactants, and amphoteric surfactants. Preferred anionic surfactants that may be used include L alkylbenzene sulfonate, α-olefin sulfonate, alkyl sulfate, polytaurin alkyl ether sulfate, and alkane Ether ether carboxylate, α-sulfonic acid fatty acid salt, soap, amido ether carboxylate, sulfonic acid succinate, amino acid ion surfactant, and the like, but are not limited to these examples. y and π are preferably non-ionic surfactants that may be used, and examples thereof include polyethylene glycol alkyl ethers, sorbose fatty acid esters, polyethylene glycols, ^^, and alkyl polyglycosides. , Fatty acid glycoside esters, fatty acid acyl glycoside esters, methylmethyl glucamine, alkylamine oxides, and the like are examples. 70 is a better example of amphoteric surfactants that may be used.

⑴ In the aromatic carboxylic acid used in the present invention, χ, Y, and Z each independently represent a group selected from the group consisting of a hydrogen atom, a methyl group, an ethyl group, and a hydroxyl group. Examples of such aromatic carboxylic acids include benzoic acid, o-hydroxybenzoic acid, benzoic acid, dimethylbenzylcarboxylic acid, ethylbenzoic acid, and dihydroxybenzoic acid. The aromatic carboxylic acid represented by the general formula (I) is preferably contained in the liquid detergent composition in an amount of 0.5 to 5. 3 (b) The conditions are used to specify the acid dissociation of the carboxyl group of the above aromatic and aromatic carboxylic acids. In general, if the pH in the system becomes higher, the acid dissociation will increase, and if the pH becomes lower, the acid dissociation will decrease. The inventors of the present case have found the following facts: In the field where the dissociation of the aromatic carboxylic acid has not been improved by 95%, the hand feeling has been significantly improved in the field where the dissociation of the aromatic acid is less than 95%. effect. in

In the Ming Dynasty, the dissociation domain below 95% is better, and the 90 J domain is better. Γ < Dissociation collar On the other hand, when the degree of acid dissociation is less than 5%, the water solubility is significantly impaired because of the proportion of all, and it is easy to be acidic at low temperatures. In the present invention, it is better to use a dissociation field of 5% or more, and ^%
