Pentaerythrityl distearate

Pentaerythrityl distearate (CAS 13081-97-5), also known as Pentaerythritol Distearate, is a partial ester of pentaerythritol and stearic acid.

Where is Pentaerythrityl distearate used?

• Plastics processing: internal lubricant and mold release agent, reducing friction between polymer chains during extrusion and injection molding of PVC and similar resins
• Personal care: spreadability and emulsion stability in lipsticks, creams, and emollient-rich skin preparations
• Metalworking lubricants: base component or additive for thermal stability and film-forming performance on metal surfaces
• Specialty coatings and wax blends: plasticizer for controlled softening and compatibility with fatty acid systems
• It functions as a plasticizer, emulsifier, and internal lubricant, helping processors and formulators improve flow, texture, and surface finish.

Commercial specifications

• Cosmetic-grade material meets purity requirements for personal care applications
• Standard packaging includes bags and fiber drums, with bulk supply available depending on the supplier
