Description

[Technical Field]

[0001] The present invention relates to a liquid detergent composition for clothing. [Background technology]

[0002] Liquid laundry detergents are used to remove various types of soiling from clothing, such as body stains, food stains, and mud stains. Surfactants used in liquid laundry detergents include anionic surfactants such as alkylbenzene sulfonates, polyoxyalkylene alkyl ether sulfates, and alkyl sulfates, as well as nonionic surfactants such as polyoxyalkylene alkyl ethers. These surfactants have the effect of removing soiling from clothing. Liquid laundry detergents containing anionic or nonionic surfactants often contain water, hydroxyl-containing organic solvents, and hydrotropes to improve ease of use and storage stability.

[0003] Patent Document 1 describes a liquid laundry detergent composition suitable for use in water-soluble unit-volume articles containing an anionic surfactant, a nonionic surfactant, 1,2-propanediol, and dipropylene glycol, with the mass ratio of the anionic surfactant to the nonionic surfactant being 5:1 to 1:1, and a specific amount of the solvent. Patent Document 2 describes a liquid detergent composition for textile products with excellent fluidity, containing 0.1 to 5% by mass of a polysaccharide polymer having a cationic group, 0.1 to 10% by mass of an aromatic sulfonate salt having a branched alkyl group having 3 to 8 carbon atoms, 15 to 60% by mass of one or more surfactants selected from anionic surfactants and nonionic surfactants, and water.

After drying, each sheet was cut at 1 / 3 of the long side and 1 / 2 of the short side to yield six test pieces, yielding a total of 48 test fabrics.

[0098] (2) Washing clothes 4.2 L of city water (3.5°dH, calculated using the water hardness measurement method described above, 5°C) was poured into a National electric bucket washing machine (model number "N-BK2"), and 2.1 g of the liquid laundry detergent composition described in Table 1 was added and stirred for 1 minute. Then, four test cloths (approximately 140 g) pretreated by the method described above were added and washed for 10 minutes. After washing, the cloths were dehydrated for 1 minute using a Hitachi two-tier washing machine (model number "PS-H35L"). Next, 4.2 L of the same city water was poured into the bucket washing machine, and the test cloth, which had been dehydrated in a Hitachi two-tier washing machine, was placed in and rinsed for 3 minutes. The same dehydration treatment was then carried out for 1 minute using the two-tier washing machine. After this treatment was repeated five times, the cloth was removed from the spin tub of the two-tier washing machine, lightly shaken, and hung up, and then left to dry for 12 hours at 25°C and 45% RH.

The folded cotton knit fabric was held between the index finger and thumb of both hands, and the index finger and thumb were slid across it. Two experts in evaluating the texture of clothing evaluated the smoothness of the fabric on a 7-point scale (in increments of 1 point) according to the following criteria.
