摘要:
The invention is a process for degreasing animal skins in which the animal skin to be degreased is contacted with a mixture of a predominantly saturated C.sub.12 -C.sub.18 fatty alcohol ethoxylate having an average of not more than 15 EO groups and a predominantly saturated C.sub.6-10 fatty alcohol ethoxylate having an average of not more than 3 EO groups.

The invention is cleaning compositions containing Polyethylene-glycol ethers of the formulaR.sub.1 --(CH.sub.2 CH.sub.2 O).sub.n --R.sub.2 (1)in whichR.sub.1 is a straight-chain or branched alkyl- or alkenyl radical having from 20 to 28 carbon atomsR.sub.2 is an alkyl radical having from 4 to 8 carbon atoms and n is an integer from about 6 to about 20as a foam-suppressing additive. The cleaning compositions are stable over a broad temperature range and having low foaming characteristics particularly at about ambient temperatures.
摘要:
Process for the production of modified triglycerides which contain epoxide groups, secondary hydroxyl groups and ether groups. The invention particularly relates to the production of reaction products of epoxidized triglycerides, for example epoxidized soy oil, with polyfunctional alcohols, for example glycols. The products so prepared are valuable starting materials, particularly for the production of alkyd resins.

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:
Polyurethane prepolymers containing terminal isocyanate groups in which oleochemical polyols are present as the polyol component. The oleochemical polyols are ring opened products or partial ring-opened products of epoxidized fatty acid triglycerides with alcohols. The use of oleochemical polyols having a residual epoxide number of from 1.0 to 4.0% by weight of epoxide oxygen is preferred. The polyurethane prepolymers are particularly suitable for use in one-component or two-component polyurethane foam formulations.
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.
