Description
Guar gum stabilizes oil-in-water emulsions by forming a viscoelastic network that increases continuous-phase viscosity.
Technical
Guar gum is a galactomannan polysaccharide that, at 0.5–2 % w/w, entangles and hydrogen-bonds to create a high‑molecular‑weight network. This network raises viscosity, reduces droplet coalescence, and extends shelf life. Its effectiveness is governed by concentration, temperature, and shear conditions.
