C12-18 and C18-unsaturated fatty acids

C12-18 and C18-unsaturated fatty acids (CAS 90990-15-1) is a mixed-chain fatty acid blend combining saturated C12–C18 fractions with unsaturated C18 species.

Where is C12-18 and C18-unsaturated fatty acids used?

• Surface treatment: surface modifier and wetting agent improving substrate adhesion and film formation in coatings and adhesives
• Lubrication: boundary lubrication in metalworking fluids and process oils
• Emulsification: emulsifier and skin-conditioning base in creams and lotions
• Cleansing formulations
• In plastics processing it functions as an internal or external lubricant and dispersing aid during compounding and extrusion.

Good to know: The physical state depends on the unsaturated-to-saturated ratio of the specific lot. Supply specifications vary by acid value, iodine value and chain length distribution.
