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. Derived from natural fats and oils, this blend functions as a multifunctional raw material.

It is used across surface treatment, lubrication, and emulsification applications in industrial and personal care manufacturing. In personal care, the blend acts as an emulsifier and skin-conditioning base in creams and lotions.

It is also utilized in cleansing formulations. Coatings and adhesives manufacturers use it as a surface modifier and wetting agent to improve substrate adhesion and film formation during the production process.

Lubricant formulators incorporate it into metalworking fluids and process oils where fatty acid chemistry provides boundary lubrication under load. This ensures high performance in demanding industrial environments.

In plastics processing, it functions as an internal or external lubricant and dispersing aid during compounding and extrusion. This material is typically supplied as a liquid or low-melting solid for easy handling.

The physical state depends on the unsaturated-to-saturated ratio of the specific lot. Technical grade is the standard commercial offering, with supply specifications varying by acid value and iodine value.

Chain length distribution is also a key factor in technical specifications. Bulk and intermediate packaging options are common for industrial buyers seeking reliable supply chains for large-scale manufacturing needs.
