The addition of up to 15 percent by weight of a polyoxyalkylene derivative to a fatty acid derived bis(alkylamidoalkyl)amine derived quaternary salt permits the atomization of the latter in conventional equipment. The resulting fabric softening product is in the desirable form of a free flowing solid, water dispersible powder.

Process for making a particulate water dispersible free flowing fabric

The present invention is directed to a dewatering aid which functions unexpectedly efficiently in the dewatering of a particulate solids slurry, e.g. mineral ore concentrate or slurry, wherein a dewatering aid is added thereto followed by filtration of the slurry. Such improved dewatering results are achieved by adding to the mineral ore slurry, an effective amount of a dewatering aid comprising an alkoxylated C.sub.6 -C.sub.11 alkanol or alkanoic acid wherein alkoxylation is conducted with propylene oxide or butylene oxide.

Ore dewatering process and compositions therefor

Disclosed is a stable, free-flowing particulate imidazoline product of the structure: ##STR1## where R.sub.1 and R.sub.2 independently are a saturated C.sub.12 -C.sub.22 alkyl group. The product is made by condensing and cyclyzing a fatty acid or ester and a polyamine wherein the molten, cyclyzed, solvent-free product is rapidly cooled to a particulate form.

Powdered imidazoline product and method for producing same

A polyol composition consisting essentially of a homogeneous liquid or low melting solid admixture of propylene glycol and a diol obtained by alkoxylating a propylene glycol dispersion of 3,3',5,5' tetrabromobisphenol A with ethylene oxide, propylene oxide or mixtures thereof. These polyol compositions are useful in preparing fire and chemical resistant thermosetting resinous compositions.
