Abstract

The invention discloses a preparation method of a liquid detergent, which comprises the following steps: adding 15-25 parts by weight of glycerol and 20-35 parts by weight of sulfonate anionic surfactant into a reaction kettle at normal temperature, stirring at 25-35 DEG C at the speed of 35 rpm, and standing for more than 50 minutes. The detergent produced by the method can reduce the phenomena of yellowing, fading and hardening of clothes after repeated washing, effectively removes various fungi, blood stains, sweat stains, milk stains, endocrines and the like, and can eliminate foreign matters and peculiar smells. The detergent has mild properties, protects clothes, and does not hurt hand skin. The detergent protects clothes fibers, and enables the underwear to be soft and bright in color after washing. The detergent has moderate foam, is easy to flush, and saves both time and labor.

Description

technical field [0001] The invention relates to a preparation method of a liquid detergent, which belongs to the field of daily chemical industry. Background technique [0002] Compared with solid detergents, liquid detergents can be energy-saving and economical products regardless of production or consumption. Liquid detergent has high technical content and strong decontamination ability. It is easy to add various ingredients in the production process, which can effectively avoid the damage caused by high alkali dosage form to clothes and hand skin; the application of phosphorus-free formula and surfactant is more Meet environmental quality requirements. And well packaged for easy use. Cotton underwear is favored by people because of its good breathability. However, after repeated washing of the worn cotton fabric, yellowing, discoloration, and hardening will occur at the collar and cuffs, and these problems cannot be solved with commercially available common detergents....
