Stearate SE
What is Stearate SE?
Stearate SE is a self-emulsifying ester derived from stearic acid and polyethylene glycol (PEG), primarily used as an emulsifier in skincare formulations to stabilize oil-in-water emulsions. It enables the creation of creamy textures in lotions, creams, and conditioners by blending water and oil phases effectively. This ingredient is valued for its ability to produce stable, aesthetically pleasing products without additional stabilizers.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Antifungal agent
Inhibits fungal growth on skin/scalp or within the product, supporting stability and helping manage fungal-related concerns depending on the application.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Antimicrobial agent
Helps limit growth of bacteria and other microbes on skin or in the formula; may be used for product protection, odor control, or targeted antimicrobial effects.
Preservative
Protects the product from microbial contamination during storage and use, helping maintain safety, stability, and shelf life.
