A charge director composition dispersed in at least one solvent comprising: A. a salt mixture comprised of 1-10 parts by weight each of: (i) a chromium salt of a C. sub. 14-18 alkyl salicylic acid; (ii) a calcium didecyl sulfosuccinate; and (iii) a salt of the didecyl ester of sulfosuccinate acid and at least 50% of the basic nitrogen radicals of a copolymer of lauryl methacrylate, stearyl methacrylate and 2-methyl-5-vinyl pyridine, said copolymer having a vinyl pyridine content of 20-30% by weight and an average molecular weight of 15,000-250,000; and B. a salt-free copolymer of (i) laurylmethacrylate and (ii) a monomer selected from 2- or 4-vinylpyridine, styrene and N,N-dimethylaminoethylmethacrylate and mixtures thereof, said copolymer having a molecular weight from about 15,000 to about 100,000, and the weight ratio of monomers B(i) to B(ii) is from about 4:1 to about 50:1; and wherein the weight ratio of B:A is from 10:3 to about 40:3.

A process is described for producing biobased 1,2-propanediol, comprising reacting a glycerol-containing feed containing less than 5 weight percent of water with hydrogen in the presence of a catalyst, to partially convert glycerol in the glycerol containing feed to a crude reaction product mixture including 1,2-propanediol, removing 10 water from the crude reaction product mixture, recovering a portion but not all of the 1,2-propanediol from the crude reaction product mixture, and recycling the remainder of the 1,2-propanediol with unconverted glycerol and combining these with makeup glycerol to provide additional of the essentially anhydrous, glycerol-containing feed.
