摘要:
Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.

摘要:
The foaming and detergent power of manual dishwashing detergents gentle to the skin and containing anionic surfactants of the sulfonate or sulfate surfactant type, fatty acid alkanolamides and fatty alkylgucosides are enhanced by using fatty alkyl C.sub.12 -C.sub.14 monoglucosides containing less than 2 glucose units per fatty alkyl group in quantities of from 3 to 20% by weight alkyl sulfate or alkylether sulfate, and from 1 to 15% by weight fatty acid alkanolamide.
摘要:
Liquid, aqueous disinfectants based on alcohol and hydrogen peroxide which contain one or more C.sub.2 -C.sub.8 alcohols, hydrogen peroxide or a compound which forms peroxide in aqueous phase, one or more carboxylic acids, one or more microbicidally active nitrogen-containing organic compounds, one or more microbicidally active phenolic compounds, and optionally other active substances and/or auxiliaries typically present in disinfectants, and to the use of such disinfectants for disinfection of the skin and mucous membrane.
摘要:
Alkyl glycosides are used to greatly increase the microbicidal activity of biguanide compounds, such as chlorhexidine salts. The alkyl glycoside/biguanide agents have a particular utility in teeth cleaning preparations due to their improved microbicidal activity against gram-positive bacteria.

Alkyl glycosides in admixture with bactericidally active alcohols or carboxylic acids in, e.g. aqueous treatment solutions, for potentiating the microbicidal effect thereof.
摘要:
A collecting agent and method for the recovery of valuable minerals in the froth flotation beneficiation of non-sulfidic ores is provided. The collecting agent is selected from alkyl glycosides, alkenyl glycosides and mixtures thereof. Preferably, the collecting agent is a combination of an alkyl glycoside, an alkenyl glycoside and mixtures thereof with a non-thio ionizable surfactant collector. Glycosides containing from about 2 to 8 glycoside residues may be used. The alkyl and alkenyl components of these glycosides may be linear or branched, may contain from about 2 to 18 carbon atoms and may optionally contain a hydroxyl group or an ether linkage.
