an adipate being an ester of adipic acid cooh ch 2 4 cooh and a sebacate being an ester of sebacic acid cooh ch 2 8 cooh phosphates are esters of phosphoric acid h 3 po 4 a sulfonamide has the typical structure rso 2 nh 2 the fatty acids are carboxylic acids derived from or contained in an animal or vegetable fat or oil they are composed of a chain of alkyl groups containing from 4 to 22 carbon atoms usually even numbered and characterized by a terminal carboxyl group cooh the generic formula for all fatty acids above acetic is ch 3 ch 2 n cooh the carbon atom count includes the carboxyl group fatty acids may be saturated or unsaturated a particularly preferred stabilizer is triethyl phosphate tep which has the formula c 2 h 5 3 po 4 tep is water soluble and compatible with solutions of peg and thus may be used in the composition of this invention without emulsification it is believed that the most suitable plasticizers for the intended purpose of this invention are polar compounds which are compatible with polyethylene glycol i e those plasticizers which do not exhibit phase separation when intimately mixed with peg the observation that many plasticizers are capable of being emulsified by peg to form a stable dispersion or emulsion in water provides a presumptive indicator of the compatibility of the plasticizer with the peg in the dry state plasticizers based on phthalate adipate sebacate phosphate and sulfonamide types are all readily emulsified with peg contrariwise it was not possible to form a stable emulsion according to the above described procedure with a non polar compound such as paraffin oil.
