Pentaerythrityl tetrastearate

Pentaerythrityl tetrastearate (CAS 115-83-3), commonly abbreviated as PETS and also marketed as Pentaerythritol tetrastearate, is a waxy ester derived from pentaerythritol and stearic acid.

It functions as an internal and external lubricant, mold release agent, and processing aid across polymer, coatings, and personal care manufacturing. In plastics processing, PETS reduces friction between polymer chains.

It is used during extrusion and injection molding, improving throughput and surface finish on engineering thermoplastics such as PVC, ABS, and polyamides. Lubricant formulators incorporate it into high-temperature grease.

Its ester structure provides film stability under load in metalworking compounds. In coatings and adhesive systems, it modifies rheology and improves substrate slip without compromising adhesion.

Personal care manufacturers use it as a structuring agent and emollient in lipsticks, creams, and hair care products where a waxy, non-greasy texture is required for the final formulation.

Pentaerythrityl tetrastearate is supplied as a white to off-white flake or powder. Technical and cosmetic grades are the most commonly stocked forms for industrial and commercial use.

Cosmetic-grade material meets purity requirements for personal care applications. Packaging typically ranges from 25 kg bags to bulk quantities depending on the specific grade and supplier requirements.
