Abstract

The present application provides a tableware detergent tablet, and methods for preparing and using the same, the tableware detergent tablet is made of the following components in parts by mass: water-soluble polymer 15-35 parts, anionic surfactant 10-25 parts, nonionic surfactant 5-20 parts, forming additive 0.3-5 parts, polyol detergency promoter 1-10 parts, water softener 1-10 parts, anti-stain dispersant 1-10 parts, enzyme formulation 0.1-5 parts, polymer cleaning co-agent 0.3-3 parts, essence 0-1 part, and preservative 0-1 part.

Claims (13)

1 . A tableware detergent tablet, wherein the tableware detergent tablet is made of the following components in parts by mass: water-soluble polymer 15-35 parts, anionic surfactant 10-25 parts, nonionic surfactant 5-20 parts, forming additive 0.3-5 parts, polyol detergency promoter 1-10 parts, water softener 1-10 parts, anti-stain dispersant 1-10 parts, enzyme formulation 0.1-5 parts, polymer cleaning co-agent 0.3-3 parts, essence 0-1 part, and preservative 0-1 part;

wherein the water-soluble polymer is at least one of polyvinyl alcohol or polyvinyl alcohol cross-linked polymer, and the water-soluble polymer has an average molecular weight of 10000-40000;

the anionic surfactant is a combination of sodium alkyl sulfate with fatty acid methyl ester sulfonate in a mass ratio of 10:(1-6);

the water softener is a combination of trisodium methylglycine diacetate and sodium citrate in a mass ratio of 3:(1-3); and

the anti-stain dispersant is a combination of sodium polyacrylate and copolymer of acrylic acid and sulfonic acid in a mass ratio of 3:(1-3).

2 . The tableware detergent tablet according to claim 1 , wherein the nonionic surfactant is at least one selected from the group consisting of alkyl glycoside, polymer of maltitol laurate and maltooligosaccharide glucoside, alcohol ether glycoside, fatty alcohol polyoxyethylene ether, isomeric alcohol polyoxyethylene ether, EO-PO block polyoxyethylene ether, modified oil ethoxylate, and fatty acid methyl ester ethoxylate, each of which has a C6-C18 carbon chain.

3 . The tableware detergent tablet according to claim 2 , wherein the nonionic surfactant is a combination of at least one of the alkyl glycoside or the polymer of maltitol laurate and maltooligosaccharide glucoside, each of which has a C6-C18 carbon chain, and any other nonionic surfactants selected from the group consisting of the alcohol ether glycoside, the fatty alcohol polyoxyethylene ether, the isomeric alcohol polyoxyethylene ether, the EO-PO block polyoxyethylene ether, the modified oil ethoxylate, and fatty acid methyl ester ethoxylate, each of which has a C6-C18 carbon chain.
