Verdict
Sodium Alginate is a naturally-derived marine polysaccharide permitted without restriction under EU Regulation (EC) No. 1223/2009. The CIR Expert Panel issued a safe as used conclusion covering use levels up to 50% in rinse-off formulations and up to 18% in leave-on products. Its high molecular weight renders dermal penetration negligible and sensitization potential is exceptionally low.
US Note
GRAS status affirmed under 21 CFR 184.1724 for direct food use (FEMA No. 2015). Permitted for cosmetic use under general FDA cosmetic ingredient provisions without pre-approval requirement. CIR Expert Panel safe as used conclusion (Final Report, October 22, 2015) serves as primary industry safety guidance.
