Abstract

The invention discloses laundry detergent laundry detergent having a good flowing state at the low temperature. The laundry detergent comprises an anionic surfactant. The anionic surfactant is prepared from a compound of isopropyl amine salt of linear alkylbenzene sulfonic acid and fatty alcohol-polyoxyethylene ether sodium sulfate (AES) and / or alpha-sodium alkenyl sulfonate. The weight-percentagecontent of the compound of the anionic surfactant is 15-20%. The content of alkylbenzene sulfonate in a product is decreased, the AES can be applied in large proportion, and the production cost is low; and the product has the good flowing state at the low temperature, the jellying phenomenon is avoided, and thickening is easy.

Description

technical field [0001] The invention belongs to the technical field of daily chemical industry, and in particular relates to a kind of laundry liquid with good flowing state at low temperature. Background technique [0002] At present, the main surfactants commonly used in laundry detergent mainly include sodium linear alkylbenzene sulfonate (LAS), sodium α-alkenyl sulfonate (AOS), sodium fatty alcohol polyoxyethylene ether sulfate (AES), fatty alcohol Sodium sulfate and fatty alcohol ethoxylates. Fatty alcohol polyoxyethylene ether sodium sulfate (AES) has the advantages of strong foaming ability, good hard water resistance, and strong detergency, so it is a common raw material for laundry detergents based on anionic surfactants. However, if the AES content in the product is high, it will easily appear in a low-temperature jelly state, and it will be difficult to flow in the low-temperature climate in winter, and the foam will increase during the washing process and it wil...
