Polyglyceryl-3 Ricinoleate

What is Polyglyceryl-3 Ricinoleate?

Polyglyceryl-3 ricinoleate is a non-ionic surfactant and emulsifier created by esterifying polyglycerol-3, derived from vegetable glycerin, with ricinoleic acid from castor oil seeds. This pale yellow, viscous liquid belongs to the polyglyceryl ester family, commonly used in cosmetics for its ability to form stable water-in-oil emulsions and anhydrous systems like lip balms, mascaras, and foundations. It functions by reducing interfacial tension between oil and water phases, creating a protective film that prevents separation and enhances product spreadability. Additionally, it solubilizes lipophilic actives such as fragrances and oils into water-based formulas, improving texture and sensory feel without greasiness.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
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.

Benefits

Delivers a smooth, softening effect on skin surfaces for better product glide.

Supports creation of stable emulsions, ensuring consistent texture in creams and lotions.

Facilitates mild cleansing and foaming in washes without stripping moisture.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
People with dry skin preferring emollient-rich, non-greasy textures.
Anyone with known allergies to castor oil derivatives.
Individuals using makeup or lip products for reliable, blendable formulas.
People sensitive to polyglycerol esters, though rare.
Those seeking gentle surfactants in cleansers for everyday routines.
Those preferring fully anhydrous or simple formulations without emulsifiers.

Safety Notes

  • Considered low hazard with no significant irritation potential in cosmetic use.
  • Non-comedogenic, unlikely to clog pores or cause breakouts.
