Problems solved by technology

[0011] However, in order to obtain a liquid cleaning agent composition that still has excellent solubility at a higher concentration, it is necessary to make almost all primary alcohol polyoxyethylene ethers and hydrotropes in the composition, while the necessary enzymes and chelating agents in the detergent Mixture and other functional ingredients can not be fully mixed

[0285] Into a 500 mL beaker, each component was put into a 500-mL beaker according to the composition shown in Tables 2 to 5, and the mixture was fully stirred with a magnetic stirrer (MITAMURAKOGYO INC.). Next, arbitrary components (except pure water) were added in the mixing amounts shown in Table 1, and pure water was added while stirring so that the total amount became 98% by mass, and further stirred. After adding an appropriate amount of pH adjuster (sodium hydroxide or sulfuric acid) so that the pH at 25°C would be 7.0, pure water was added so that the total amount would be 100% by mass to obtain a liquid cleaning composition.

[0286] Various measurements and evaluations were performed on the obtained liquid cleaning composition. The results are shown in Tables 2-5.

[0287] In addition, the unit of the compounding quantity in Tables 2-5 is mass %, and the arbitrary component shows the purity conversion quantity.

Abstract

The invention relates to a liquid detergent composition includes: a component (A) which includes a nonionic surfactant represented by the formula R 1 O(CH 2 CH 2 O) n H; a component (B) which includes at least one species of anionic surfactant selected from the group consisting of compounds represented by the formulas R 2 CH(SO 3 M 1 )COOR 3 and R 4 CH(SO 3 M 2 )CONHR 5 ; and a component (C) which includes at least two species of water-miscible solvents selected from the group consisting of methanol, ethanol, propanol, butanol, ethylene glycol, propylene glycol, butylene glycol, butyl carbitol, phenoxy ethanol, and polyethylene glycol with an average molecular weight of 570 to 3800, wherein the total amount of the component (A) and the component (B) is in the range of 40 to 75 % by mass and the mass ratio of the amount of the component (B) with respect to the total amount of the component (A) and the component (B) satisfies component (B) / (component (A)+component (B)) =1 / 10 to 6 / 10. The invention can provide a liquid detergent composition which includes a surfactant at a high concentration and which has superior low-temperature preservation stability and superior low-temperature solubility and sebum detergency during washing.

Description

technical field [0001] The present invention relates to liquid cleaning compositions. [0002] this application claims the priority based on Japanese Patent Application No. 2009-238354 for which it applied to Japan on October 15, 2009, The content is used here. Background technique [0003] In recent years, the development of eco-friendly products has become increasingly important, and in the field of daily necessities such as laundry detergents, products that take into account the global environment are being sought. For example, in order to reduce energy consumption during logistics and reduce waste generation, detergent containers are being miniaturized. Correspondingly, in order to make a small amount of detergent exert a higher sebum washing ability, a concentrated liquid detergent is required. Concentration of a liquid detergent requires that it does not gel even if it is diluted with water during washing, and that it does not reduce the ability to cleanse sebum. Es...
