摘要

Invention patent: "hidrofu00eclico rate for laundry detergents lu00ecquidas aqueous compositions, containing them.Liquid laundry detergent composition having a very concentrated surfactant system.The surfactant system comprises of from about 0.1% to about 20%, by weight, of the system of surfactant from a surfactant of alkyl benzene sulfonate.And where the system of surfactant has a hydrophilic index, HL ~ C ~, from 8.0 to 9.2.The index hidrofilico is calculated as follows: HL ~ C ~ = sym ~ y ~ (% in weight of surfactant and surfactant system) x (HL ~ s ~ ~ y ~)HL ~ s ~ ~ y ~ is calculated for each of the surfactant in surfactant systems as follows: HL ~ s ~ ~ y ~ x = 20 (the molecular weight of the hydrophilic portion of the component Y of the surfactant) / (molecular weight).The component Y of the surfactant).
