Abstract

A low-temperature efficient liquid detergent composition consists of, by weight, anionic surface agent 8-15%, non-ionic surface active agent 2-5%, anionic surface agent containing branched chains 5-14%, 4A zeolite 15-25%, sodium carbonate 2-6%, sodium silicate 2-6%, sodium citrate 0-5%, de-flocculating agent 0.005-0.5%, fluorescent brightener 0-0.1%, enzyme for washing 0-1%, preservative 0-0.1%, essence 0-0.2% and the balance water. The low-temperature efficient liquid detergent composition has the advantages of being good in low-temperature cleaning performance, hard water resisting performance and water-saving performance.

Description

technical field [0001] The invention belongs to a detergent and its preparation process, in particular to a low-temperature high-efficiency liquid detergent composition and its preparation process. Background technique [0002] Modern liquid detergents began in the late 1940s, and were fully developed and popularized in the 1970s and 1980s. After the 1990s, with the rapid development of science and technology, liquid detergents have made greater progress in terms of quality and quantity. , The proportion of washing products is rising rapidly. In recent years, with the rapid rise in the price of raw materials such as petroleum, the production cost of manufacturers has increased significantly, but at the same time it has given them greater motivation to break through the previous inherent formula system and seek new raw materials and new technologies . Surfactants will still be the key components of decontamination in future detergents, and more attention will be paid to sur...
