Fatty acids, C12-18, mixed esters with citric acid, pentaerythritol

Fatty acids, C12-18, mixed esters with citric acid, pentaerythritol is a complex ester built from medium- to long-chain fatty acids, citric acid, and pentaerythritol. It functions as a multifunctional emulsifier, lubricant, and moisturizing agent across personal care and industrial formulations.

Identified by CAS 130328-22-2, this versatile chemical stabilizes oil-in-water and water-in-oil emulsions while contributing a smooth, conditioning skin feel in body care products. Coating and adhesive formulators use it to improve substrate wetting.

In polymer-based systems, it provides essential internal lubrication. In metalworking and industrial lubricant blends, it acts as a boundary lubricant additive, reducing friction between metal surfaces under moderate load conditions.

Personal care manufacturers also incorporate it into lip care and leave-on formulations where both emulsification and humectant performance are required in a single ingredient. This product is typically supplied as a waxy solid or viscous paste.

The physical state depends on the specific fatty acid chain distribution of the batch. Technical and cosmetic grades are the most commonly available, with cosmetic-grade material meeting purity and color standards for leave-on applications.

The material is suitable for both leave-on and rinse-off personal care applications. Bulk supply is standard in drum and IBC quantities to meet the high-volume demands of industrial and cosmetic manufacturing facilities worldwide.
