Main functionalities
Emulsifier for anhydrous topical formulations. Emulsifier for difficult-to-formulate emulsions (solvents and large oily phase). Stabilizes and improves sensorial and texture properties. Safety of use is inferred by precedence of use in approved pharmaceutical products.
Main formulation technologies
Topical emulsion and foam (with aerosol). One-pot formulation process can facilitate manufacturing.
