Problems solved by technology

Due to the high content of active substances, when the active substance reaches 60% or more, the highly concentrated laundry detergent formula is prone to solution gel and poor dispersion in water. Dissolving, it is easy to form a gel during the production process, which makes the production operation process difficult and it is difficult to obtain the ideal product

Abstract

The invention discloses a highly concentrated laundry detergent, which comprises: an environment-friendly solvent, sodium alkanol polyether sulfate, C12‑13 alkanol polyether, C12‑14 sodium olefin sulfonate, and water. The concentrated laundry detergent has an active ingredient of 60%, is easy to produce and can form industrialized production, is not toxic to aquatic organisms, is environmentally safe, and responds to national calls for environmental protection and energy saving. The concentrated laundry liquid has the advantages of easy dispersion and dissolution during use, short action time, convenient use, less dosage, less irritation, strong decontamination ability, no harm to human body, etc.; it is suitable for wide use in civil and public places.

Description

technical field [0001] The invention relates to the field of daily chemicals, in particular to a highly concentrated laundry detergent. Background technique [0002] At present, domestically produced laundry detergents are mostly ordinary, with an active substance content of about 20%. In developed countries, concentration has become the main trend of sustainable development and technological innovation of the detergent industry. In 2008, the content of surfactants in laundry detergent in the Western European market was generally 15% to 45%, and the active substance of a certain brand product was even as high as 55%. [0003] Highly concentrated laundry detergent can further greatly save the packaging and transportation costs of enterprises, and reduce unnecessary energy waste. Due to the high content of active substances, when the active substances reach 60% and above, the highly concentrated laundry detergent formula is prone to solution gel and poor dispersion in water....
