1. INCI e CAS

INCI: Glycerin · CAS: 56-81-5

2. Ruolo nella formula

Cosmetic washes, gels, and emulsions use glycerin in a polyol-humectant role; the listed level is for formulation development.

3. Livelli d'uso tipici (guida di formulazione)

• The level shown for gels and serums is 3–8% in this reference.
• The level shown for creams is 2–5% as a formulation guide.
• For rinse-off, use 2–4% for the formula.

Incorporate Glycerin in the water phase without a separate melt step.

4. Fonti normative e conformità globale

• An entry for Glycerin in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
• Regulation (EC) No 1223/2009 requires an assessment addressing the safety of the finished product that contains Glycerin for the complete formula intended for sale.
• Use the supplier TDS to confirm grade-specific details for Glycerin and review the destination market's requirements.

5. Sicurezza e valutazione del rischio

The listed use rate is intended as a cosmetic-development guide; no drug approval or OTC-monograph status follows from this guide and the finished formula still needs patch and stability testing.

6. Stabilità e packaging

Hold the bulk material in a sealed, cool place shielded from light; select packaging with the formula's oxidation sensitivity in mind; test the selected package with the confirmed batch for stability and fit.

7. Linguaggio dei claim (cosa dire / cosa non dire)

• The listed cosmetic direction for Glycerin emphasizes humectant function.

• The listed information cannot substantiate drug claims, cure claims, or a certification that is absent from the product records.
• The information about Glycerin does not establish skin whitening, treatment of acne, sweat control, UV protection, or hair-growth results.

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

The use-level note is a reference for cosmetic formulation; the listed level does not itself confer drug or OTC status with patch and stability testing still needed for the completed formula.

6. Stabilità e packaging

Protect sealed bulk from warmth and direct light; for oxidation-sensitive formulas, consider an airless or pump pack; test the selected package with the confirmed batch for stability and fit.

• Review the documentation for the actual Sodium Hyaluronate grade and the filing requirements for the target market.

5. Sicurezza e valutazione del rischio

Use the stated level as reference guidance for cosmetic formulation; this reference is not approval for drug use or OTC marketing with patch assessment and finished-formula stability testing still required.
