Polyglyceryl-3 Dicitrate/Stearate

Polyglyceryl-3 dicitrate/stearate is a synthetic emulsifier derived from polyglycerin and fatty acids. It belongs to the polyglyceryl ester family — ingredients designed to blend oil-soluble and water-soluble components together, preventing them from separating in a formulation.In skincare products, it serves primarily as an emulsifying agent, helping to create stable creams, serums, and lotions. It is used in relatively small quantities (typically under 1%) and is found in a small proportion of skincare products overall.

This ingredient works by positioning itself at the boundary between oil and water molecules. One part of its molecular structure is attracted to oils, whilst another is attracted to water, allowing these naturally incompatible substances to mix and remain blended rather than separating into layers.This emulsifying function is purely cosmetic — it does not penetrate the skin or alter skin physiology, but instead ensures that other actives in the formula are distributed evenly and remain stable.

This ingredient does not require any special application method — simply use the product as directed by the manufacturer. Because it is a formulation ingredient rather than an active, its benefit comes from being part of a stable, well-designed formula rather than from targeted application.

Generally well-tolerated and approved for use in cosmetics. Some individuals with fungal acne sensitivities may wish to verify the full product formulation, as certain emulsifiers have been anecdotally associated with triggering fungal acne in susceptible skin.
