Request SDS →Self-emulsifying propylene glycol monostearate is an emulsifier blend based on propylene glycol monostearate combined with a small amount of anionic soap to give self-emulsifying behavior. It is used as an emulsifier and texture agent in cosmetic and food formulations.
Frequently Asked Questions
What is propylene glycol monostearate used for?
Self-emulsifying propylene glycol monostearate is used as an emulsifier and texture agent. It serves as a self-emulsifying base for creams and lotions in cosmetics, as an emulsifier and texture agent in food formulations, and as an oil-in-water emulsifier and opacifier in emulsion systems.
Is propylene glycol monostearate an emulsifying agent?
Yes. It is a nonionic emulsifier (CAS 9004-99-3, formula C20H40O3) within the surfactant family. The self-emulsifying grade combines propylene glycol monostearate with a small amount of anionic soap so it disperses without added co-emulsifiers, stabilizing oil-in-water systems.
What makes the self-emulsifying grade different from standard PGMS?
The self-emulsifying grade incorporates a small fraction of anionic soap alongside the propylene glycol monostearate ester. That added anionic component lets the material form emulsions on its own, whereas a non-self-emulsifying ester typically requires a separate primary emulsifier in the formulation.
What CAS number and packaging is bulk propylene glycol monostearate available in?
This material is supplied under CAS 9004-99-3. RawSource distributes it in industrial bulk formats for manufacturers; for available pack sizes (drums, totes, IBCs), MOQ, and a current price, request a bulk quote with your target volume.
Can you provide a CoA and SDS for this emulsifier?
Yes. A Certificate of Analysis and Safety Data Sheet are available with each shipment. Request both with your quote so your formulation and incoming-QC teams can review identity, specification, and handling information before ordering.
