Recommended Uses & Known Applications

ISOFOL Alcohols and their derivatives are used as raw materials and intermediates in many application areas including:

  • Lubricants – converted to esters having improved hydrolytic stability and lower pour points than linear counterparts.
  • Cosmetics and Pharmaceuticals – an odorless ingredient of creams, lotions, and ointments.
  • Personal Care – sulfate derivative gives low foaming cleansing.

Technical Details & Test Data

Melting points of ISOFOL alcohols in comparison with linear NACOL alcohols

The ISOFOL alcohols C12 to C24 are liquid at ambient temperature, whereas corresponding linear and saturated alcohols are solid. While oleyl alcohol starts to solidify at approx. 10 °C, ISOFOL alcohol of similar chain lengths remains liquid
