Science
Mechanism of Action
This ingredient functions primarily as an emollient, forming a thin, protective film on the skin's surface to significantly reduce trans-epidermal water loss, thereby boosting moisture retention and improving the skin's texture. Its amphiphilic nature, possessing both hydrophilic and lipophilic characteristics, allows it to serve as a crucial co-emulsifier, stabilizing oil-in-water formulations. Additionally, it acts as a humectant, drawing moisture into the stratum corneum, and contributes to product viscosity as a thickening agent.

Stability
Glyceryl Isostearates is primarily soluble in oil, exhibiting very low water solubility, estimated at 0.01421 mg/L at 25 °C. Despite this, its emulsifying properties are vital for integrating oil and water phases, thus enhancing emulsion stability in cosmetic products. Optimal formulation stability is observed within a precise pH range of 6.0 to 7.0.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Glyceryl Isostearates is safe for use in cosmetic applications under current practices and concentrations. Regulatory bodies including the FDA and EU Cosmetic Regulation approve its inclusion in personal care products. While undiluted glyceryl monoesters may cause minor irritation, particularly on abraded skin, concentrations typically used in cosmetics are not considered irritating.
