Expert Verdict

Natural galactomannan from carob (locust bean) seeds (Ceratonia siliqua). Distinguished by its synergistic interaction with xanthan gum โ€” combining the two creates elastic gels at concentrations where neither ingredient would gel independently. This xanthan + locust bean gum synergy is a standard approach for cost-effective elastic gel textures in cosmetics. Fully biodegradable and exempt from EU REACH SPM restriction. COSMOS/ECOCERT compliant.
