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.

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.
Abstract: Clear aqueous gels prepared from certain polyoxybutylene-polyoxyethylene block polymers are used for topically applied cosmetic and pharmaceutical compositions and remain gels at refrigerator and freezer temperatures.
Abstract: Highly stable emulsions of biocides in liquid fertilizer compositions are disclosed which offer unexpected stability thus permitting application of both biocides and liquid fertilizers simultaneously. The improved emulsion stability can be obtained by utilizing higher polyoxyalkylene glycol ethoxylate esters or combinations thereof with certain anionic emulsifiers. Stable aqueous emulsions are also disclosed.

Abstract: The process and polyoxyalkylene compound prepared by reacting 4,4'-thiodiphenol with at least one alkylene oxide in the presence of a base catalyst.
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.

Abstract: This invention relates to polymer dispersions prepared by the in situ polymerization of an ethylenically unsaturated monomer or mixture of monomers in a chain extender in the presence of a free radical polymerization initiator and a polyamide stabilizer. The invention also relates to mixtures of the polymer dispersions with compounds having two or more active hydrogen atoms as determined by the Zerewittinoff method. These mixtures are used to prepare polyurethane products.
Abstract: Easily dispersible alkali blue pigments with high color strength are obtained if the pigment is precipitated in the presence of (1) primary, secondary or tertiary aliphatic amines, (2) N-alkylamino alkanic acid, (3) a diaryl or triarylamine, (4) an acid or neutral aliphatic ester of phosphoric acid, (5) a half ester of sulfuric acid based on fatty alcohol, fatty alcohol-EO adducts or alkyl phenol-EO adducts, (6) an alkane or alkene sulfonic acid on a dialkylsulfimide, (7) EO adducts based on alkylphenols, alkanols or alkylamines, (8) polypropylene glycol or PO/EO block copolymers based on alkane diols or alkane polyols or in the presence of mixtures of these compounds or is mixed with at least one of the substances listed under (1) to (8) after the precipitation with acid in the acid suspension and is isolated.Alkali blue pigments are obtained which are easily dispersible in offset printing ink varnishes and which result in excellent color strength of the printed matter.
Abstract: Polyisocyanurate foams are prepared from reacting partially etherified methylolmelamines either alone or in mixture with polyoxyalkylene polyether polyols with polyisocyanates. Improved friability and flame retardancy are obtained.

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.
