Weak-acid low-foam liquid detergent composition

The invention relates to the field of detergents, and discloses a weak-acid low-foam liquid detergent composition, the total active matter content is 15-30 wt%, and the weak-acid low-foam liquid detergent composition comprises the following components: 5-15 wt% of modified grease ethoxylate sulfonate, 4-8 wt% of a fatty alcohol polyether type nonionic surfactant, 0.5-2.0 wt% of a thickener polyethylene glycol difatty acid ester, 0.5-1.5 wt% of long-chain fatty acid, an alkali neutralizer, 0-10 wt% of other auxiliaries and a solvent. The liquid detergent composition disclosed by the invention is weakly acidic, so that the liquid detergent composition has the characteristics of lower irritation, more skin friendliness and no injury to hands, and on the basis, the liquid detergent composition also successfully realizes that fatty acid is introduced into a weakly acidic system; and introducing the modified grease ethoxylate sulfonate into the weakly acidic system under the condition that the viscosity of the syst
