Swapnroop Pharma manufactures and supplies Polysorbate 40, a nonionic surfactant used as an emulsifier, wetting agent, dispersing agent and stabilizer in formulation systems. Polysorbate 40 is also known as Polyoxyethylene (20) Sorbitan Monopalmitate and is derived from sorbitan monopalmitate through ethoxylation.
Its amphiphilic structure combines a hydrophilic polyoxyethylene chain with a fatty-acid-derived hydrophobic portion, allowing it to support emulsification and improve the dispersion of formulation ingredients.
Polysorbate 40 is a member of the Polysorbate family and contains palmitic acid as its principal fatty-acid component. It is generally supplied as a viscous liquid or semi-solid material depending on grade and temperature.
The product can assist in stabilizing mixtures containing aqueous and oil-soluble components and may be selected when a nonionic surfactant with palmitate functionality is required.
Depending on the applicable grade and regulatory requirements, Polysorbate 40 can be used in:
