Expert Verdict
The benchmark natural thickener with exceptional pH stability (2-12), excellent salt tolerance, and outstanding particle suspension. Pseudoplastic/shear-thinning properties prevent sedimentation at rest while enabling easy spreading under shear. Fully biodegradable and COSMOS/ECOCERT compliant. Best used at 0.1-1.0% in synergistic blends with locust bean gum or sclerotium gum.
