Laundry powdered soap with no phosphor and benzene

Abstract

This invention discloses phosphorus and benzene-free washing powder, which comprises: sodium fatty acid ethyl ester sulfonate 10-20 parts, soap base 15-25 parts, fatty acid diethanolamide 3-5 parts, fatty alcohol polyoxyethylene ether 3-5 parts, filler 40-60 parts, water 3-10 parts, essence 0.1-0.5 part, preservative 0.01-0.5 part, and bactericide 0.01-0.5 part. The filler comprises sodium sulfate 35-50 parts, and sodium silicate 5-10 parts. The washing powder is neutral, and does no harm to human bodies or environment. The surfactant does not comprise cancerigenic substances, and there are not cancerigenic substances formed during preparation.

Description

technical field [0001] The invention belongs to the field of washing products, and in particular relates to a phosphorus-free and benzene-free laundry soap powder. Background technique [0002] For detergents such as washing powder, sodium alkylbenzene sulfonate is often used as a surfactant. The disadvantage is that sodium alkylbenzene sulfonate contains benzene rings and is a carcinogen; It has good detergency under certain conditions, so when washing clothes, it will cause damage to protein fibers, and if it is washed by hand, it will also have an adverse effect on the skin; third, in order to increase the washing effect, it is often necessary to add sodium tripolyphosphate as a water softener , and the discharge of phosphorus-containing substances pollutes the environment. As an alternative product, people use fatty acid methyl ester sulfonate as a surfactant in detergents to replace the original active ingredients. This product can avoid the shortcomings of detergents ...

[0002] For detergents such as washing powder, sodium alkylbenzene sulfonate is often used as a surfactant. The disadvantage is that sodium alkylbenzene sulfonate contains benzene rings and is a carcinogen; It has good detergency under certain conditions, so when washing clothes, it will cause damage to protein fibers, and if it is washed by hand, it will also have an adverse effect on the skin; third, in order to increase the washing effect, it is often necessary to add sodium tripolyphosphate as a water softener , while the discharge of phosphorus-containing substances pollutes the environment

As an alternative product, people use fatty acid methyl ester sulfonate as a surfactant in detergents to replace the original active ingredients. This product can avoid the shortcomings of detergents in which sodium alkylbenzene sulfonate is the active ingredient. , is a phosphorus-free and benzene-free washing product. The washing powder and other washing products produced by fatty acid methyl ester sulfonate have the advantages of avoiding environmental pollution, significantly improving the washing effect, preventing damage to the fibers of the washed fabric, and not hurting the fabric. Human skin and other advantages; but in the process of preparing fatty acid methyl ester sulfonate with fatty acid methyl ester, there will inevitably be by-product methyl sulfate, and methyl sulfate has recently been found to have the possibility of carcinogenesis
