The processes comprise providing biologically produced 1,3-propanediol, contacting the 1,3-propanediol with organic acids, which produces the esters, recovering the esters, and incorporating the esters into personal care formulations. Also provided are processes of making a personal care composition comprising providing an ester of 1,3 propanediol and mixing the ester with an acceptable carrier to form a personal care composition.
