INCI: SODIUM LACTATE
Sodium Lactate (CAS 72-17-3) is a cosmetic humectant functioning as pH buffering agent; humectant; moisturizer. NOAEL 1330 mg/kg bw/day (cross-referenced against ToxValDB ECHA IUCLID); EU Regulation 1223/2009 status: permitted. Industrial safety data is also available in the chemical safety database. Same-CAS public records also appear in industrial chemical safety, pharmaceutical, and food safety data.
US NotesGRAS under 21 CFR 184.1768 for food use (emulsifier, flavor enhancer, humectant, pH control). Permitted in cosmetics under FDA general safety requirement. CIR Expert Panel (1998, re-reviewed 2017) concluded AHAs including sodium lactate are safe at <=10% concentration at final formulation pH >=3.5, when formulated to avoid increasing sun sensitivity or with daily sun protection labeling.
