Poloxamer 188

Poloxamer 188 is a synthetic polymer derived from ethylene oxide and propylene oxide. It belongs to a class of ingredients called poloxamers, which are widely used in pharmaceuticals and cosmetics as emulsifiers and surfactants.In skincare, its primary role is to help blend water and oil-based components that would otherwise separate. This allows formulators to create stable, uniform products with improved texture and consistency.

Poloxamer 188 is an emulsifier with a unique molecular structure: one end attracts water while the other attracts oil. This allows it to position itself at the interface between incompatible ingredients, holding them together and preventing them from separating.Beyond emulsification, research in clinical settings has explored poloxamer-based hydrogels as delivery systems for therapeutic agents in wound care, suggesting it may also play a supporting role in maintaining skin hydration and product efficacy when incorporated into more complex formulations.

Poloxamer 188 is used at low concentrations within finished products, so there are no specific usage instructions to follow. Simply use your formulation as directed. Its presence will not affect how you apply your skincare routine, though it contributes to the overall stability and feel of the product.

Poloxamer 188 is generally well-tolerated and has a long safety history in both pharmaceuticals and cosmetics. It is suitable for most skin types, including sensitive skin, though individual sensitivities remain possible.
