Compound detergent sheet

Abstract

The invention discloses a compound detergent sheet. The compound detergent sheet comprises a fiber layer, a first washing layer, an active enzyme layer and a second washing layer, wherein the first washing layer is arranged on the fiber layer; the second washing layer is arranged on the first washing layer; the active enzyme layer is arranged between the first washing layer and the second washinglayer; the first washing layer is prepared from the following components in parts by weight: 10 to 15 parts of fatty alcohol polyoxyethylene ether, 10 to 15 parts of fatty alcohol polyoxyethylene ether sodium sulfonate, 2 to 5 parts of epichlorohydrin dimethylamine polymer, 0.02 to 0.1 part of disodium ethylene diamine tetraacetate, 1 to 3 parts of sorbitol, 2 to 4 parts of thickening agent, 0.5 to 2.0 parts of film forming agent, 0.2 to 1.2 parts of molding auxiliary agent, 0.1 to 1.0 part of pH (Potential of Hydrogen) regulator and 10 to 40 parts of de-ionized water; the second washing layeris prepared from the following components in parts by weight: 10 to 15 parts of the fatty alcohol polyoxyethylene ether, 10 to 15 parts of the fatty alcohol polyoxyethylene ether sodium sulfonate, 0.02 to 0.1 part of the disodium ethylene diamine tetraacetate, 1 to 10 parts of wetting agent, 2 to 4 parts of thickening agent, 0.5 to 2.0 parts of film forming agent, 0.2 to 1.2 parts of molding auxiliary agent, 0.1 to 1.0 part of pH regulator, 0.1 to 1.0 part of essence and 10 to 40 parts of de-ionized water. The invention provides the compound detergent sheet with good stability and multifunctionality.

Description

technical field [0001] The invention relates to the technical field of daily chemical industry, in particular to a composite laundry sheet. Background technique [0002] Laundry sheets are more and more popular among consumers because of their portability. Laundry tablets overcome the cumbersome metering in the use of traditional washing powder and laundry detergent, which saves washing supplies. At the same time, the low-foaming and super-concentrated characteristics of laundry tablets save water, so laundry tablets are expected to be promoted in China. [0003] However, most laundry tablets currently on the market do not contain active enzymes, so it is difficult to remove protein, grease and other stains in the actual washing process. In addition, a small number of enzyme-containing laundry tablets generally use active enzymes added to the slurry, and the enzymes are prone to lose activity when encountering high temperatures during batching and drying, and this enzyme-co...
