DETERGENT COMPOSITIONS.

摘要

The present invention provides a detergent composition for effectively releasing both muddy soil and oily soil deposited on polyester fibers in water at not more than 30 degree C. A detergent composition for use in washing of polyester fibers in washing water at a temperature of not more than 30 degree C comprising: (i) from 0.05 to 2 percent by weight of a methyl cellulose ether wherein its solution viscosity measured at a temperature of 20 degree C as a 2 wt.percent aqueous solution is from 80 to 120 centipoises (cps) and its average degree of methyl substitution (DS methyl) per anhydroglucose is from about 1.6 to about 2.3; (ii) from 25 to 65 percent by weight of a detergent surfactant; (iii) from 0 to 20 percent by weight of a bleaching component; and (iv) from 30 to 70 percent by weight of a builder and an alkaline material.
