Abstract

The invention discloses low-temperature instant soap powder and a preparation method thereof. The low-temperature instant soap powder comprises the following raw material components in percentages by weight: 10-85% of acid component; 1-40% of alkali component; 0-40% of assistant; and 1-50% of surfactant. The preparation method of the low-temperature instant soap powder, provided by the invention, comprises a step of reacting a precursor of soap (including the acid component and the alkali component) with the assistant and the surfactant so as to form microscopic combination or linkage with the soap, the other assistant and the surfactant, thereby improving the solubility of the soap powder greatly and reducing a Kraft point of the soap powder; and the low-temperature instant soap powder has the low-temperature instant effect.

Description

technical field [0001] The present invention relates to a kind of daily-use chemicals and its production process, more precisely, the present invention relates to the flowable chemical produced by in-situ reaction of a kind of acid and alkali components and corresponding components on auxiliary agents and surfactants Low temperature instant soap powder. Background technique [0002] Soap powder, as a synthetic detergent with relatively high sodium fatty acid content, is loved by some consumers in China. Our country issued a standard for laundry soap powder in 2008, standard number: QB / T 2387-2008. It is marked that the content of sodium fatty acid is greater than or equal to 7%. The well-known brands of soap powder in the market include Chaoneng, Diaopai, Liby and other brands. However, when consumers use soap powder, they also find a very headache problem, which is poor solubility, which is significantly different from washing powder, especially at low temperature, that ...
