Cationic surface-active agents which are polyhydroxylated tertiary amines or the quaternary ammonium salts thereof and which are usefully employed in cosmetic compositions, are prepared by condensing on a fatty alcohol, glycerol epihalohydrin alone or together with an epoxide to form polyhalogenated polyethers, which in turn are converted to polyhalogenated glycidyl ethers, the latter being reacted with a secondary amine to form polyhalogenated tertiary amines which are then reacted with sodium or potassium acetate in the presence of a diol to form said polyhydroxylated tertiary amines.
A photosensitive composition is prepared from a mixture of a photosensitive resin containing radicals having the formula ##STR1## wherein X and Y represent hydrogen, halogen, cyano or nitro, Ar represents an aryl radical or a substituted aryl radical, and n represents 1 or 2, and a solvent having the formula ##STR2## wherein R and R" represent a lower alkyl radical and R' represents a lower alkylene radical.

The present invention is directed to a water-soluble polyether glycol polymer having: a structural backbone of carbon atoms and oxygen atoms where there are at least two consecutive carbon atoms present between each oxygen atom; a moiety on the backbone of the polymer or a functionalized derivative on the polymer, that is cationic at physiological pH and permits complexation with phosphate or oxalate; and an average molecular weight from about 5,000 to about 750,000 Daltons. These polymers are formulated for oral dosage to reduce the phosphonate or oxalate levels in an animal. The process of preparing these polymers and the method of reducing gastrointestinal absorption of phosphate and oxalate are included.
