Wax alcohols
The wax alcohols form a subgroup of the saturated unbranched alkanols . They form a homologous series with the sum formula C n H 2n + 1 OH with n ≥ 24. The boundary between the fatty alcohols and the wax alcohols is fluid. It is set at the number of carbon atoms of 24, i.e. starting with lignoceryl alcohol (C 24 H 49 OH).
