Abstract

A detergent sheet and a preparation method thereof are provided; the preparation method comprises the following steps: A, adding pure water into a reactor, stirring, and adding sodium hydroxide until full solution; B, adding dodecylbenzene sulfonic acid under stirring, stirring until clarification, fully reacting until solution PH is neutral; C, adding fatty alcohol polyoxyethylene ether until clarification, adding sodium dodecyl sulfate and ethylene diamine tetraacetic acid, and continuing to stir for 5 min until clarification; D, adding cocamidopropyl betaine slowly, stirring until transparency, adding plant aroma extract, and continuing to stir for 10 min; E, stirring well the above materials, injecting to a mold plate, drying and forming, and sheeting and bagging. The detergent sheet is composited with a water-soluble surfactant, has good deterging power and facilitates rinsing; the detergent sheet has a neutral formulation and is friendly to clothes and hands; each detergent sheet is less than 10 g in gram weight, one detergent sheet is used each time, and the detergent is convenient to use and store.

Description

technical field [0001] The invention relates to a daily chemical solid-state washing, more specifically to a super-concentrated laundry tablet and a preparation method thereof. Background technique [0002] At present, the washing products on the market are mainly three types of laundry detergent, laundry soap and washing powder, which dominate people's daily life. However, first, the high alkalinity of washing powder will cause certain damage to the clothes or skin in direct contact, and it also contains a large amount of inorganic salt components, which are difficult to rinse off when left on the clothes; It is composed of detergent and various additives, and the clothes are easy to rinse after washing. More than 70% of its ingredients are water, and the weight of a single bottle reaches more than 3kg, which is inconvenient to take and transport; 3. Laundry soap is light, has good detergency, and mild nature It does not hurt clothes and hands, but it is easy to soften and...
