Lubricants
Fatty acids are formulated into non-polar products as lubricity additives or corrosion inhibitors. In grease manufacture they are reacted with alkali’s to help form the soap thickener matrix. When neutralised with a base, fatty acids become water dispersible and are used in aqueous metal working or metal rolling applications as emulsifiers, corrosion inhibitors and lubricity additives.

bio based and include the below:
- Oleic acid
- Isostearic acid
- Dimer / Trimer acid
- Azelaic acid
Oleic acid and isostearic acids are monomer acids.
Dimer and trimer acids are formed through the conversion of unsaturated fatty acids(oleic acid) into a 36 carbon chain (dimer) or C54 carbon chain (trimer). They are extremely hydrophobic, have multiple free acid groups and are thicker than monomer fatty acids.
Azelaic acid is a C9 di-acid formed through the ozonolysis of oleic acid and widely used in the formulation of greases.
Isostearic acid is a branched, saturated acid which combines excellent oxidative stability with low pour points. This is ideal for applications that require both high and low temperature operation such as greases.
Our fatty acid range allows a formulator to choose bio stability or biodegradability. Dimer acid is biostable for improved in-service life, important in applications such as fuel additives; whereas oleic acid and isostearic acid are both readily biodegradable and therefore suitable for Environmentally Acceptable Lubricants (EAL's), such as European Ecolabel compliant lubricants.
Being 100% biobased, the full range is appropriate for products that require high bio-based content, such as those meeting the USDA’s BioPreferred program.
