Concern level

High concern

Ceratonia siliqua (carob) gum, also known as locust bean gum, is a high-molecular-weight galactomannan polysaccharide obtained from carob seed endosperm. In cosmetics it functions primarily as a thickener, stabilizer, viscosity builder, and texture modifier in water-based formulations, helping improve slip and suspension without contributing oiliness or occlusion.

Interactions

incompatible with: No major incompatibilities are established for normal cosmetic use., Powdered/aerosolized applications may increase inhalation irritation risk., Can lose viscosity if formulation architecture is poorly balanced with high electrolyte loads or extreme processing, so bench testing is recommended.

Risks & Warnings

Generally low-risk in topical cosmetic use. Potential concerns are rare sensitization in individuals with legume/carob allergy and mild ocular or respiratory irritation if used in powder/aerosolized formats. CIR also notes tannins and trypsin inhibitors have been detected in ceratonia siliqua gum, but cosmetic use is considered safe at present practices. No meaningful phototoxicity or acne risk is expected.
