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.

A process for preparing alkyd resin emulsions where a precondensate is further condensed to an acidic precondensate which is esterified to yield a resin which is then emulsified, and the products of this process.
摘要:
Alkyd resins containing functional epoxides as long-chain modifying agents. The functional epoxides used are selected from the following:(a) epoxidized unsaturated fatty alcohols containing from 16 to 22 C-atoms,(b) esters of epoxidized fatty acids and monofunctional alcohols containing from 1 to 18 C-atoms,(c) epoxidized triglycerides,(d) reaction products of epoxidized triglycerides containing in the molecule epoxide groups and secondary hydroxyl groups formed by ring opening.The alkyd resins according to the invention are distinguished by particularly good weathering properties.
摘要:
The aqueous paste contains an alkyl glucoside as non-ionic surfactant and an .alpha.-sulfofatty acid disalt as anionic surfactant; a thickener, for example carboxymethy cellulose, may also be present for adjusting viscosity. The paste-form detergent is produced by mixing concentrated aqueous pastes of the surfactants and, optionally, the thickener, the pH optionally being adjusted to a substantially neutral value by addition of a regulator. The paste-form detergents are suitable both for the washing of laundry and for the washing of hard surfaces, for example dishes.
摘要:
A process for the production of alcohol polyglycol ethers by reaction of an alcohol with ethylene oxide and/or propylene oxide wherein a basic alkali metal compound catalyst is employed in at least 0.5% by weight, expressed as sodium methylate, and based on the total weight of the reactants. The reaction mixture is neutralized in the presence of a filter aid.
摘要:
Soiled textile articles are washed by the addition of a determined amount of a detergent concentrate containing surfactants to the textile articles to be cleaned while the textiles are dry or only damp. The aqueous washing liquor is formed by the gradual addition of water to the textile articles while they are rotated. At room temperature, the detergent concentrate is to a substantial extent a paste-to dough-like substance, stable in form, and is applied to the textile articles in such an amount that the major portion of the surfactants together with further detergent constituents, if desired, are applied to the textiles or on an article of textile provided with markings for the correct detergent dose, as a dosing aid.

摘要:
Reactive resin systems suitable for cast-molding polyurethanes comprise reactive isocyanates and chain extenders for the isocyanates comprising polyol addition products of C.sub.1 -C.sub.8 alcohols and epoxidized triglyceride oils: if desired, the polyol addition products used have been alkoxylated with C.sub.2 -C.sub.4 -alkylene oxides.
摘要:
New oil components for cosmetic and pharmaceutical applications consist of reaction products of epoxidized triglyceride oils with monohydric alcohols containing from 1 to 4 carbon atoms. The oil components are produced by reacting an epoxidized triglyceride oil containing from about 4 to about 8% by weight of epoxide oxygen, preferably an epoxidized soya bean oil containing from about 6 to about 7% by weight of epoxide oxygen, in the presence of an acidic catalyst with a monohydric C.sub.1 -C.sub.4 -alcohol, preferably methanol, in excess at the boiling temperature of the alcohol until the oxirane rings have been completely opened, followed by neutralizing the catalyst and distilling off the excess alcohol. The new oil components are eminently suitable, inter alia, for the production of cosmetic stick preparations.
