Expert 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.
