Problems solved by technology

Surfactants used in super-concentrated liquid detergent formulations are usually non-ionic and anionic. slow, will cause it to form gel or produce layering phenomenon, it is difficult to form a stable product with uniform transparency, good fluidity, easy to pour, easy to use, and gel phenomenon will appear when mixed with water during washing, resulting in product solubility Deterioration, reduced use efficiency, difficulty in fully exploiting the performance of ultra-concentrated detergents

Abstract

Hyper-concentrated liquid detergent comprises, in percentage by weight, 8-30% of anionic surfactant, 40-60% of nonionic surfactant, 5-15% of cosolvent, 0-10% of auxiliary, 0.005-1% of deflocculant, 0-0.5% of fluorescent brightener, 0-2% of detergent enzymes, 0-0.1% of preservative, 0.1-1% of essence, and the balance of water. The hyper-concentrated liquid detergent has the advantages of high solid content and high deterging effect.

Description

technical field [0001] The invention belongs to a liquid detergent and its preparation technology, in particular to a super-concentrated liquid detergent and its preparation technology. Background technique [0002] As environmental protection and the green movement have gained widespread attention around the world, mild, natural, concentrated, easily degradable, and renewable pollution-free green products that meet environmental protection requirements will become the mainstream in the production and consumption of detergents in the future. Products with low consumption and low pollution will be more and more favored by consumers. On the other hand, due to changes in the living environment and the general improvement in hygiene awareness, consumers' requirements for washing and perceptions of dirt have also changed. Consumers require detergents not only to clean the visible dirt on clothes, but also to completely remove odors. Therefore, popularizing and applying energy-s...
