Glyceryl Stearate Citrate

Glyceryl Stearate Citrate is a gentle, plant-derived emulsifier that keeps water and oils blended in cosmetic products while softening the skin.

Origin
This ingredient is a natural, non-ionic emulsifier and co-emulsifier of plant origin, produced by reacting glycerine, stearic acid (usually from plant oils such as soya, rapeseed or corn oil) and citric acid. Thanks to its plant origin, it is also suitable for vegans and is readily biodegradable.

How it works
The main function of Glyceryl Stearate Citrate is to stabilise oil-in-water (O/W) emulsions, creating light, smooth and non-greasy product textures. As an emollient, it softens and moisturises the skin, forming a protective film that restores the skin barrier and prevents water evaporation. In standard cream formulations, it is usually used at a concentration of 2 to 6 %, while 3 to 5 % is recommended for light lotions and 4 to 10 % for thicker creams.

Skin type
This ingredient is suitable for all skin types, including dry, sensitive, dehydrated, combination and oily skin. Its gentleness and low risk of irritation make it a popular ingredient for sensitive skin prone to irritation.

Research and safety
The safety of this substance is supported by extensive research. In its official 2017 report, the Cosmetic Ingredient Review (CIR) research panel confirmed that Glyceryl Stearate Citrate is safe for use in cosmetic products at concentrations up to 5 %, with no evidence of irritation, sensitisation or toxicity when used correctly. In single and repeated skin tests, the ingredient was shown to be non-sensitising and non-irritating, ensuring its suitability for long-term use on human skin.
