Cremophor? A25 is a nonionic surfactant and emulsifier produced by BASF. It belongs to the Cremophor series, which are polyethylene glycol (PEG)-based compounds widely used in pharmaceuticals, cosmetics, and industrial formulations.
Key Features:
Composition: Derived from cetylstearyl alcohol (a mix of cetyl and stearyl alcohols) reacted with ethylene oxide (25 moles), forming a PEGylated fatty alcohol (PEG-25 hydrogenated castor oil derivative).
Function: Acts as a solubilizer, emulsifier, or stabilizer for hydrophobic substances in aqueous systems.
Applications:
Pharmaceuticals: Enhances solubility of poorly water-soluble drugs (e.g., in injectables, oral liquids, or topical creams).
Cosmetics: Used in creams, lotions, and ointments for texture and stability.
Safety: Generally regarded as safe in regulated concentrations, though PEG derivatives may cause sensitization in rare cases. Always adhere to formulation guidelines.
Notes:
HLB Value: Likely has a hydrophilic-lipophilic balance (HLB) suited for oil-in-water emulsions (exact value depends on structure).
Regulatory: Complies with pharmacopeial standards (e.g., USP/NF, EP) for pharmaceutical use.
For precise technical specifications (e.g., viscosity, pH stability), consult BASF’s product datasheet.
