    摘要: 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: 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.
