Polyglyceryl-3 Ricinoleate

Polyglyceryl-3 ricinoleate is an emulsifier derived from castor oil and glycerin. It belongs to a class of ingredients called polyglyceryl esters, which are produced by esterifying glycerin with fatty acids. In skincare products, it functions as an emulsifying agent, helping to stabilise formulations by allowing water and oil-based ingredients to mix together evenly.As an emulsifier, it works at the interface between water and oil phases, reducing surface tension and preventing separation. This makes it useful in creating stable creams, lotions, and other mixed formulations where disparate …

Polyglyceryl-3 ricinoleate stabilises emulsions through its molecular structure, which contains both water-loving (hydrophilic) and oil-loving (lipophilic) regions. These regions position themselves at the boundary between water and oil, creating a protective layer that prevents the two phases from separating.This mechanism allows skincare products to maintain a consistent texture and ensure that active ingredients remain evenly distributed throughout the product's shelf life and during application to skin.

This ingredient is typically found in finished formulations rather than used as a standalone product. If using a product containing polyglyceryl-3 ricinoleate, follow the manufacturer's instructions for that formulation. There are no specific application techniques that optimise this ingredient's emulsifying function — it works during the product's manufacture and maintains stability during use.

Polyglyceryl-3 ricinoleate is generally well-tolerated and considered safe for cosmetic use in typical concentrations. Some users with fungal acne-prone skin may prefer to avoid products with this ingredient, though evidence linking it specifically to fungal acne is anecdotal.
