Description
Glyceryl monooleate is a non‑ionic surfactant that forms stable oil‑in‑water emulsions when heated above 45 °C.
Technical
Its hydrophilic‑lipo‑philic balance (HLB) of ~12 allows the molecule to orient at the oil‑water interface, reducing interfacial tension by 30–40 % at 60–70 °C. The resulting flexible interfacial film resists coalescence, producing uniform droplet sizes and a smooth, creamy texture.
Science
Primary Reaction
