摘要:
Improved mouldability and surface smoothness is provided for moulded detergent compositions, for example bar soaps, containing from 30 to 70% by weight of a sodium C.sub.12 -C.sub.18 alkyl sulfate, from 5 to 25% by weight of a C.sub.12 -C.sub.18 fatty alcohol, from 5 to 25% by weight palmitic and/or stearic acid, optionally partially saponified, and from 1 to 30% by weight of an .alpha.-sulfofatty acid salt corresponding to the following formula ##STR1## wherein R.sup.1 is a linear C.sub.9 -C.sub.21 alkyl group, A is an alkali metal, ammonium or alkanolammonium cation, and B is hydrogen or has one of the meanings of A.
摘要:
Soil-collecting detergency enhancers for detergent solutions comprising a substantially water-insoluble polyfunctional quaternary ammonium compound or a water-soluble polyfunctional quaternary ammonium compound fixed to a water-insoluble solid carrier. The detergency enhancers may be used in the cleaning of soiled articles, particularly those soiled with pigments, in aqueous detergent solutions such as for washing fabrics.
摘要:
Alkyl hydroxyalkyl orthophosphoric acid esters, particularly mixtures thereof, corresponding to the following formula ##STR1## in which R.sup.1 and R.sup.2 represent C.sub.6 -C.sub.22 alkyl groups and R.sup.3 is hydrogen, a group R.sup.1 or a group --CH.sub.2 --CH(OH)--R.sup.2. The esters are prepared by reaction of phosphorus pentoxide with fatty alcohol and reaction of the phosphoric acid partial esters formed with long-chain .alpha.-epoxides. After conversion of the compounds corresponding to formula I, in which R.sup.3 is hydrogen, into the salt form, the new alkyl hydroxyalkyl orthophosphoric acid ester mixtures are particularly suitable as emulsifiers for oil-water emulsion.
摘要:
The method of using polyfunctional quaternary ammonium compounds which are at least substantially insoluble in an aqueous fabric detergent solution and/or are fixed to solids correspondingly insoluble in such aqueous solution, as a soil-collecting, concentration-reducing agent for reducing the demand for conventional detergent components in the aqueous solution.
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:
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.
