PEG-100 Stearate (CAS 9004-99-3) is a nonionic surfactant, the polyethylene glycol (100 EO) monoester of stearic acid. It is used as an oil-in-water emulsifier and emulsion stabilizer in personal-care creams, lotions and related formulations.

Frequently Asked Questions

What is PEG-100 stearate?

PEG-100 Stearate (CAS 9004-99-3) is a nonionic surfactant — the polyethylene glycol (100 EO) monoester of stearic acid. It functions as an oil-in-water emulsifier and emulsion stabilizer in creams, lotions and related formulations.

What is PEG-100 stearate made from?

It is produced by esterifying stearic acid (a C18 fatty acid) with polyethylene glycol of about 100 ethylene-oxide units. The result is a hydrophilic nonionic emulsifier commonly paired with a co-emulsifier such as glyceryl stearate.

Is PEG-100 stearate water soluble?

The high ethylene-oxide content (100 EO) makes PEG-100 Stearate strongly hydrophilic, so it disperses and solubilizes well in water and serves as the hydrophilic partner in O/W emulsifier pairs. Exact solubility behavior depends on the formulation; consult the technical data sheet.

How is bulk PEG-100 stearate supplied?
