Abstract: Disclosed is a novel composition of the formula: ##STR1## wherein R=H, methyl, ethyl, or a mixture thereof and R.sup.5 =a saturated or unsaturated alkyl group from a fatty acid containing 7 to 22 carbon atoms and a+b=n, wherein n is from about 2 to 80, resulting from alkoxylating an substituted imidazolidone, reductively aminating the alkoxylated product and reacting the aminated product with a fatty acid; and, to its use as a surfactant in glycol-water mixtures, such as, for example, propylene glycol based wing deicers thickened with polyacrylic acids.

Abstract: Disclosed is an ethylene glycol based deicing/anti-icing composition which contains a thickener comprising a polyacrylic acid having a molecular weight of from about 90,000 to 100,000 and a wetting agent from the group consisting of nonylphenol ethoxylates, alkarylsulfonates, polyoxyethylene phosphates and tetrafunctional block copolymers of EO/PO on an ethylene diamine backbone and demonstrates improvement in anti-icing ability as measured by holdover time while not adversely effecting aerodynamic performance or Newtonian rheology of the deicer measured by passing the minimum requirements of the AMS test for Type I fluids.

Abstract: Anti-icing compositions, such as used on aircraft wing surfaces, may be thickened using a blend of a polyacrylic acid and a copolymer of polyacrylic acid with a vinyl monomer, where the copolymer acts as a thickener modifier. Additional advantages are obtained when a low molecular weight nonionic alkylphenol ethoxylate surfactant is used in conjunction with an alkylaryl sulfonate hydrotrope, as additives. This latter combination of additives gives anti-icing compositions with increased holdover times with no degradation of other properties. The compositions also contain an alkylene glycol component, such as propylene glycol, diethylene glycol and mixtures thereof. These compositions retain a high viscosity, even when diluted with water, and exhibit a highly pseudoplastic rheology indicating desirable flow off characteristics.

Abstract: De-icing compositions, such as used on aircraft wing surfaces, are found to not need thickeners to obtain acceptable holdover times. The compositions are based on an alkylene glycol component (such as propylene glycol, diethylene glycol and mixtures thereof), and obtain particular advantage when a nonionic alkylphenol ethoxylate surfactant is used in conjunction with an alkylaryl sulfonate hydrotrope, as additives. This latter combination of additives gives de-icing compositions with increased holdover times with no degradation of other properties. These compositions exhibit a Newtonian rheology as required for de-icing compositions.
