  • Patent number: 4468478
    Abstract: The oxidation promoting harmful effects of the presence of an alkaline catalyst in a polyoxyalkylene can be eliminated and the product made more resistant to oxidation especially at elevated temperatures by the incorporation therein of soluble salts of certain benzoic acid derivatives. The soluble salts can be formed by reaction with the alkali or alkaline earth metal ion derived from the alkaline catalyst utilized in the polymerization of the polyoxyalkylene.

  • Patent number: 4465661
    Abstract: Oral products such as mouthwashes and dentifrices are disclosed which utilize a polyoxyethylene derivative of a fatty alcohol having 15 to 20 carbon atoms wherein the polyoxyethylene chains are responsible for about 50 to about 90 percent of the molecular weight of the surfactant. Unexpectedly, the nonionic surfactants solubilize peppermint oil and other flavorants at ambient temperatures and below so that the mouthwash compositions of the invention remain clear and haze free. The visually clear dental creams of the invention also maintain their clarity at ambient temperatures and below. Both mouthwash and dental creams of the invention are free of the usual bitter surfactant taste.

  • Patent number: 4458038
    Abstract: White graft polymer dispersions in polyoxyalkylene polyether polyols are employed together with flame retardant compounds to prepare flame retardant polyurethane foams. The polymer dispersions employ less than 0.1 mole of induced unsaturation per mole of polyol mixture. Improved processes for the preparation of these polymer dispersions employ either maleate or fumarate derived polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol with a compound selected from the group consisting of maleic acid, maleic anhydride and fumaric acid and an alkylene oxide in the presence of salts and oxides of divalent metals.

  • Patent number: 4450091
    Abstract: It has been found in accordance with the instant invention that the viscosity of a shampoo formulation based on a blend of amphoteric and nonionic surfactants could be considerably enhanced by replacement of a part of the amphoteric surfactant with an anionic surfactant. The shampoo compositions also contain as essential ingredients both an alkanolamide and a polyoxyalkylene glycol fatty ester. These shampoo products are characterized by increased viscosity as well as mildness towards the eyes and superior foam compared to some leading commercial products.The nonionic surfactant is a cogeneric mixture of conjugated polyoxybutylene-polyoxyethylene compounds containing in their structure oxybutylene groups, oxyethylene groups and an organic radical derived from an organic compound containing a pluarlity of reactive hydrogen atoms.
