Glycerin
Humectant
1. INCI et CAS
INCI: Glycerin · CAS: 56-81-5
2. Rôle dans la formule
The listed glycerin role is that of a polyol humectant in cosmetic washes, gels, and emulsions; the amount is guidance only.
3. Niveaux d'emploi typiques (repère de formulation)
- For gels and serums, use 3–8% as a formulation guide.
- The level shown for creams is 2–5% for the formula.
- For rinse-off, the recorded level is 2–4% for the formula.
The water phase is the addition point for Glycerin; a separate melt is unnecessary.
4. Sources réglementaires et conformité mondiale
- If Glycerin appears in CosIng, its entry is informational and does not approve a specific grade or finished cosmetic.
- For a cosmetic sold in the EU, Regulation (EC) No 1223/2009 requires a safety assessment covering the complete formulation with Glycerin before the finished product is marketed.
- For Glycerin, check the purchased grade against its supplier TDS and review filing requirements in the destination market.
5. Sécurité et évaluation des risques
Use the stated level as reference guidance for cosmetic formulation; it makes no claim of drug or OTC authorization with patch response and finished-product stability still to be verified.
6. Stabilité et conditionnement
Hold the bulk material in a sealed, cool place shielded from light; review airless or pump options if oxidation presents a concern; follow with stability and packaging checks on the confirmed batch.
7. Formulations d'allégations (à faire / à éviter)
- The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.
- The ingredient guidance does not demonstrate claims of drug activity, a clinical cure, or an undocumented product certification.
- This reference for Glycerin should not be cited in support of whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
