ISOFOL 20 is a primary, saturated alcohol with defined branching of the carbon chain. Such alcohols are chemically described as 2-alkyl-1-alkanols and are also referred to as Guerbet alcohols. It is a high purity alcohol that offers excellent oxidative and color stability. Additionally, the twin, 100% linear alkyl branches of the ISOFOL alcohol give it a lower viscosity and better biodegradability than dimer alcohols derived from oxo-alcohols. The unique chemical structure of ISOFOL alcohol also provides good solubility and solvency.

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
