Cyamopsis Tetragonoloba (Guar) Gum

Concern level

High concern

Cyamopsis Tetragonoloba (Guar) Gum is a high-molecular-weight galactomannan polysaccharide obtained from guar bean endosperm. In cosmetics it functions mainly as a viscosity-increasing agent, thickener, stabilizer, and texture enhancer. It is water-dispersible, helps improve slip and product feel, and can support emulsion stability and suspension of insoluble particles. CIR has reviewed it as a safe cosmetic ingredient, and PubChem describes guar gum as a water-soluble plant mucilage with neutral-pH aqueous solutions.

Interactions

incompatible with: High electrolyte/salt loads can reduce viscosity in some gum systems., Strongly cationic polymers may alter rheology or cause complexation depending on formula design., Excessive borate or crosslinking systems can drastically change gel behavior.

Risks & Warnings

Generally low risk. Main concerns are rare sensitivity or contact allergy in very reactive users, and occasional product performance issues if overused (stringiness, tack, pilling). Because it is plant-derived, poorly purified material could theoretically contain trace impurities, but this is a manufacturing-quality issue rather than an intrinsic toxicologic concern.
