Documented Uses

• Used as intermediates; Fatty alcohols with chain lengths >18 are used to prevent evaporation of water reservoirs during dry seasons; Naturally occurring in lanolin and green leaf composite samples; [HSDB]
• The industrial importance of fatty alcohols is due to the large number of reactions that the hydroxyl group may undergo ... many of the resulting derivatives are intermediates of commercial importance /Fatty alcohols/
• Fatty alcohols with chain lengths greater than 18 ... are suitable for protection of water reservoirs against evaporation during dry seasons ... evaporation can be reduced up to 50% /Fatty alcohols/
• This chemical is listed as a High Production Volume (HPV) (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and/or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B; 51FR21438).
• Lanolin was saponified and extracted with petroleum ether. The natural fraction of lanolin obtained (wool wax alcohols) was treated with digitonin. After thin-layer chromatography, 5 fractions were isolated from the digitonin-negative fraction from which several steroidal hydrocarbons, including lignoceryl alcohol, were isolated.
