LIQUID DETERGENT COMPOSITION WITH IMPROVED WASHING DURABILITY

摘要

PURPOSE: A liquid detergent composition is provided, to improve low temperature stability, dissolving power and washing durability. CONSTITUTION: The liquid detergent composition comprises 15-30 wt% of an anionic surfactant; 10-20 wt% of a nonionic or cationic surfactant; and 0.01-2 wt% of an inorganic salt. Preferably the ratio of the nonionic or cationic surfactant to the anionic surfactant is 30:70 to 50:50 by weight. Preferably the inorganic salt is at least one selected from the group consisting of NaCl, Na2SO4, MgCl2 and MgSO4; and the anionic surfactant comprises the P-type surfactant having a linear alkyl group and a hydrophilic group combined to a terminal and the S-type surfactant having hydrophilic group combined to the middle part of an alkyl chain in the ratio of 90:10 to 40:60 by weight.
