- For an EU-market product, Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Glycerin rather than for an ingredient name alone.
- Review the supplier TDS for the received Glycerin grade, together with the target market's current filing requirements.
5. Sicurezza e valutazione del rischio
The listed use rate is intended as a cosmetic-development guide; it is not evidence of drug approval or OTC authorization so patch response and stability should be checked on the finished product.

Keep the bulk container closed and shaded in a cool area; review airless or pump options if oxidation presents a concern; check the finished batch's stability and package compatibility.
