CHR

8/10

Concern level

High concern

Solvent extract derived from Chondrus crispus (Irish moss/red seaweed). In cosmetics it is mainly used as a skin-conditioning and viscosity-controlling ingredient; it can also contribute humectant-like feel and film-forming, soothing, and texture-enhancing effects. COSMILE Europe lists it as a skin-conditioning and viscosity-controlling ingredient, and PubChem/CIR identify it as a cosmetic ingredient with safe use in current practices.

Interactions

incompatible with: No well-established topical incompatibilities are documented for typical cosmetic use., In very acidic or very alkaline systems, botanical polysaccharides may show viscosity changes, so formulation testing is recommended.

Risks & Warnings

Generally low risk, but any botanical extract can rarely trigger irritation or allergy in sensitive users. Seaweed-derived materials may vary by source and processing; quality control matters. If the raw material contains trace iodine/mineral contaminants, those are formulation-quality concerns rather than an inherent topical hazard.
