Bis(2-ethylhexyl) adipate

CAS: 103-23-1

Overview

Bis(2-ethylhexyl) adipate ( CAS 103-23-1 ), commonly known as DOA or Diethylhexyl adipate, is a low-temperature plasticizer and lubricant ester used across food packaging, personal care, and industrial applications.

It keeps flexible PVC and other polymer systems pliable at sub-zero temperatures where standard phthalate plasticizers lose performance. In food-contact film and packaging, DOA is approved for use as a plasticizer.

This material is essential where low-temperature flexibility and regulatory compliance are both required. Personal care formulators incorporate it as an emollient and skin-conditioning agent in creams, lotions, and color cosmetics.

In these applications, it contributes a light, non-greasy skin feel. Industrial lubricant manufacturers use it as a base fluid or additive in synthetic lubricants and metalworking fluids for broad operating temperature ranges.

It also functions as a flavor solvent and carrier in food applications, where its food-grade status supports use in direct and indirect contact scenarios. DOA is supplied as a clear, low-viscosity liquid.

The product is available in bulk quantities including IBC totes and road tankers. Food-grade and technical-grade designations are the standard commercial grades available in the market for various industries.

Specifications typically align with FCC requirements for food-contact applications and technical purity standards for industrial use. This ensures high performance and safety across all manufacturing sectors.
