Polyglyceryl-5 Polyricinoleate

What is Polyglyceryl-5 Polyricinoleate?

Polyglyceryl-5 Polyricinoleate is an ester formed from polyglycerol-5 and polyricinoleic acid, a modified fatty acid sourced from castor oil seeds. This plant-origin ingredient falls into the polyglyceryl esters category, widely used in makeup foundations, lipsticks, creams, and cleansers. It excels as an emulsifier by creating a protective film at the oil-water interface, stabilizing complex formulations with high pigment or oil content to prevent separation. Its surfactant action reduces surface tension, promoting even ingredient dispersion, while its viscosity-controlling properties allow precise texture adjustments, from fluid lotions to rich balms. This multifunctional role supports reliable performance in diverse cosmetic systems, maintaining homogeneity and usability over time.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Stabilizes emulsions for consistent product texture and longevity

Adjusts viscosity to improve spreadability and feel

Facilitates even dispersion of pigments and oils in makeup
