Dicetyl phosphate

Dicetyl phosphate (CAS 2197-63-9 ), also known as dipalmityl phosphate, is an anionic phosphate ester derived from cetyl alcohol used as an emulsifier and surface-active agent across personal care, pharmaceutical, and industrial applications.

It functions primarily to stabilize emulsions, modify surface charge, and control rheological behavior in formulated systems. In cosmetic and topical pharmaceutical formulations, it acts as an anionic emulsifier in creams and lotions.

This chemical contributes to droplet stabilization and improves the texture of oil-in-water systems. It is used in liposomal and vesicular drug delivery systems, where its negative surface charge helps control membrane stability.

The compound also improves encapsulation efficiency in these specialized delivery systems. In personal care products such as sunscreens and moisturizers, it modifies interfacial tension to support uniform pigment or active dispersion.

Plastics and polymer processing applications utilize it as a surface modifier and processing aid where controlled wetting of substrates is required. This versatility makes it a staple in advanced material manufacturing.

The product is supplied as a white to off-white waxy solid or flake. It is available in cosmetic-grade and pharmaceutical-grade specifications to meet the purity requirements of regulated formulation environments.

Packaging options typically range from kilogram-scale bags to bulk quantities suited for industrial procurement volumes. Our supply chain ensures consistent quality for large-scale manufacturing and specialized laboratory use.
