Propane-1,3-diol phosphatides of the formula ##STR1## are prepared from the corresponding 1-alkanoyl-propanediols by conversion o an intermediate alkanoyl-propanediol-phosphoric acid .beta.-bromoethyl ester with .beta.-bromoethylphosphoric acid dichloride, and amination of the intermediate. They are biodegradable surfactants useful in detergent compositions and as emulsifiers in foods. In the formula, n is an integer and 9 to 25, R.sub.1 and R.sub.2 may be hydrogen or alkyl having up to six carbon atoms, and R.sub.3, R.sub.4, R.sub.5 may be hydrogen or methyl, but at least one of R.sub.3, R.sub.4, and R.sub.5 is hydrogen when R.sub.1 and R.sub.2 are both hydrogen.
