Problems solved by technology

[0003] (1) Phosphates such as sodium tripolyphosphate are used in traditional washing powder, which seriously pollutes the environment. With the discharge of washing sewage, it will cause eutrophication in water areas, resulting in the death of a large number of organisms and causing environmental pollution; 4A zeolite in aluminosilicate is also used in the powder as an auxiliary agent to replace phosphate, but 4A zeolite itself is also a water-insoluble substance, which is easy to adhere to the surface of the clothes and is not easy to rinse. cause some damages
As mentioned above, it is not advisable to use phosphate or aluminosilicate as auxiliary agents in washing powder. Existing washing powder or laundry balls use these two materials as main auxiliary agents, so the use safety is low and it is harmful

Abstract

The invention discloses a solid clothes laundering composition coated with a polymeric membrane. The composition is obtained by coating a solid washing material by using the polymeric membrane, wherein the polymeric membrane has the functions of anti-redeposition and calcium ion and magnesium ion coordination; the polymeric membrane comprises a dirt dispersion agent, an anti-redeposition agent and an auxiliary material; the washing material comprises an anionic surfactant, a nonionic surfactant, a cationic surfactant and a washing assistant. The solid clothes laundering composition is easily dispersed in the water during washing, the water source pollution can be reduced, the calcium ion and magnesium ion can be effectively coordinated, the hard water can be softened and the redeposition of the dirt can be prevented; besides, the solid clothes laundering composition is convenient to use, easy to quantify, simple in package and low in cost.

Description

technical field [0001] The invention relates to the technical field of laundry cleaning agents, in particular to a solid laundry composition with an outer layer coated with a polymer film and a preparation method thereof. Background technique [0002] Commonly used laundry detergents in life have washing powder, laundry detergent etc. and have been widely used. Existing washing powder and laundry detergent are usually mixed with surfactants, auxiliary agents, additives, fillers, etc. to make. Traditional washing powder and laundry detergent have the following problems: [0003] (1) Phosphates such as sodium tripolyphosphate are used in traditional washing powder, which seriously pollutes the environment. With the discharge of washing sewage, it will cause eutrophication in water areas, resulting in the death of a large number of organisms and causing environmental pollution; 4A zeolite in aluminosilicate is also used in the powder as an auxiliary agent to replace phosphate,...
