1. INCI & CAS
INCI: Glycerin · CAS: 56-81-5

3. Typical use levels (formulation guide)
- Gels and serums may use the guide range 3–8% in this reference.

4. Regulatory sources & global compliance
- The CosIng record for Glycerin, where listed, is informational rather than product-specific authorization.
- Regulation (EC) No 1223/2009 sets the requirement for the complete cosmetic containing Glycerin to receive its own safety assessment before the finished product is marketed.
- Use the supplier TDS to confirm grade-specific details for Glycerin and review the destination market's requirements.
5. Safety & risk assessment
Use the stated level as reference guidance for cosmetic formulation; it is not evidence of drug approval or OTC authorization and the completed formula still requires stability and patch testing.
6. Stability & packaging
Protect sealed bulk from warmth and direct light; match the pack choice to the system's oxidation risk; check the final package and formula together for compatibility and stability.
