Detergent compositions containing monoesters produced through esterifying dibasic or polybasic organic aliphatic carboxylic acids and/or dibasic or polybasic aromatic carboxylic acids with alcohols. These monoesters replace in the detergent previously used phosphates which caused eutrofication and endangered the ecology.
A solid detergent composition for cleaning hard surfaces comprises an active detergent constituent which also serves as a carrier material, and a cleaning constituent. The cleaning constituent can comprise an acidic material, which is effective to remove soap scum from hard surfaces, or a bleach functional at a basic pH which is effective to bleach mildew. The detergent constituent comprises the essentially anhydrous neutralization product of an anionic surfactant such as a linear alkylbenzene sulfonic acid and a solid neutralizing material, such as a salt, oxide, or hydroxide of an alkali or alkaline earth metal, including sodium carbonate. The cleaning constituent, along with a filler material, is added to the detergent constituent during the course of and prior to the termination of the neutralization reaction. Also disclosed is a reusable scrubber pad incorporating the solid detergent composition. Within other aspects of the invention are solid, acidic cleaning compositions containing at least one polycarboxylic acid, solid cleaning compositions containing a bleach functional at a basic pH, and methods for manufacturing and using both the acid pH and the basic pH solid cleaning compositions.
Salts of aromatic 1,2-dicarboxylic acids having hydrophobic groups attached to the benzene ring, especially alkali metal salts of C.sub.10 -C.sub.20 alkyl and alkenyl phthalic acids, are used as detergency builders.
Ethers of 1,2-disubstituted tartaric acid esters proved to be excellent initiators for thermally initiatable radical polymerization reactions. They show a high reactivity even in low concentrations and yield thoroughly hardened products.
A machine dish washing process wherein a detergent is given such a composition and/or is dispersed over the crockery in such a way that with the detergent a cleaning layer with an appearance distinct from water is formed on preferably at least substantially the complete surface of the crockery, which distinction preferably can be discerned by the naked eye.
The present invention provides a cleaning solution for recycling a waste copy paper with toner-images formed on the surface of the copy paper, comprising water, a monoester of bivalent organic acid, a surface active agent and an organic acid.
