peg-20 stearate
binomial name: polyethylene glycol (20) stearate
PEG-20 stearate is a nonionic emulsifier derived from stearic acid and ethylene oxide. Stearic acid itself is a fatty acid naturally found in plant oils, while the PEG portion enhances water solubility and stability. This combination allows oil and water phases to blend seamlessly, forming smooth, uniform emulsions. Widely used in modern cosmetic chemistry, it supports texture refinement while maintaining formula clarity and consistency.
benefit: In skincare formulations, PEG-20 stearate functions primarily as an emulsifier and solubilizer. It helps distribute botanical oils evenly within water-based systems, contributing to a balanced, silky texture. By stabilizing emulsions, it ensures product performance and shelf integrity. Its presence enhances the sensory elegance of creams and cleansers, allowing plant-based ingredients to perform harmoniously within the formula.
