Glyceryl Stearate Citrate is an emulsifier and skin-conditioning agent commonly used in cosmetic and personal care products. It is derived from the esterification of glycerin, stearic acid, and citric acid.
Glyceryl Stearate Citrate has the ability to blend oil and water-based ingredients, helping to stabilise and create a smooth, uniform texture in formulations. GlycerylStearate Citrate is a palm-free glyceryl diester oil-in-water emulsifier made of glycerin and fatty acids derived from vegetable oils. It acts as a hydrophilic, PEG-free, anionic o/w emulsifier and emollient.
It is well suited for emulsions with a slightly acidic pH-value or emulsions with UV filters. It supports the consistency and the oil binding capacity and can also be used as co-emulsifier for PEG-free formulations. Provides a soft and smooth appearance on the skin and can be used also for sensitive skin.
Acts as an emulsifying agent, helping to blend water and oil phases in formulations.
Provides a smooth and creamy texture to cosmetic products.
Enhances the stability and shelf life of emulsions.
Can function as a mild surfactant.
HLB value 12 (gives oil-in-water emulsions).
Directions for use:
Add pellets to the hot oil phase (approx. 80oC / 176oF) and stir until homogeneous. Combine then with hot water phase. Typical use level 1.5-2.5%. This product produces stable emulsions from pH 5.5 - 8.0.
