Benzoxazoles having the structure <IMAGE> where R is hydrogen or an alkyl group having from 1 to 20 carbon atoms, R' is hydrogen, chlorine or an alkyl group containing from 1 to 20 carbon atoms, X is H or Chlorine and the total number of carbon atoms in R and R' is 6 to 40 with the proviso that one of R and R' must be an alkyl group of at least 6 carbon atoms.
