Expert Verdict

Strong natural thickener at low concentrations (0.1โ€“0.8%) delivering creamy texture; synergistic with xanthan gum in mixed-gel systems. pH range limited to 4โ€“9, susceptible to hydrolytic degradation below pH 4. Overdosing causes stickiness. Fully biodegradable and COSMOS/ECOCERT compliant. Best suited to near-neutral pH formulations; avoid in acidic serums or toners below pH 4.
