• Match the selected Glycerin material to its supplier TDS and check the filing list for the market of sale.

5. Sicurezza e valutazione del rischio

Treat the listed amount as cosmetic-development guidance; it provides no evidence that a drug or OTC monograph applies so the finished cosmetic should receive patch and stability checks.
