Esterol 10S


Esterol 10S is an inactive sulfur donor additive made of vegetable sulfurized esters (10% sulfur) compatible with mineral, synthetic base oils and greases.


Key property: bio-based.


CAS number
Chemical name
Fatty acids C16-18 and C18-unsatd., Me esters, sulfurized
Common name


Thanks to its polar head groups and fatty chains, Esterol10S improves lubricity and anti-wear properties, while extending extreme-pressure performances without corroding copper alloys. Esterol10S is recommended for the formulation of neat and soluble metal working fluids (with a preference to yellow metals such as copper and alloys) as well as for industrial lubricants. Esterol10S can be formulated solely or in combination with other products within the TPS range (i.e. enhanced anti-wear & extreme-pressure properties in combination with TPS®20). Esterol10S is produced from renewable vegetable raw materials and therefore, is the ideal alternative to sulfurized lards.
