Concern level

High concern

A magnesium salt of carboxymethylated beta-glucan, used in cosmetics as a skin-conditioning and soothing polymer. It is generally positioned as a barrier-support supportive humectant/film-former with low sensitization potential and is especially common in calming, recovery, and sensitive-skin formulations.

Interactions

incompatible with: No major incompatibilities are established in the reviewed sources., Use formulation caution with strong oxidizers or extreme pH systems if the finished formula destabilizes polymer performance.

Risks & Warnings

Overall low-risk ingredient. Main concerns are rare individual sensitivity or intolerance to beta-glucan-derived materials; because it is a polymeric conditioning agent, systemic toxicity concerns are not typical at cosmetic use levels. No specific pregnancy contraindication is established in the sources reviewed. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/18505493/?utm_source=openai))
