Glycerin
Humectant
1. INCI et CAS
INCI: Glycerin · CAS: 56-81-5
2. Rôle dans la formule
Glycerin serves as the polyol humectant in these cosmetic formats, while the stated percentage remains a formulation reference.
3. Niveaux d'emploi typiques (repère de formulation)
- For gels and serums, use 3–8% for the formula.
- For creams, the recorded level is 2–5%.
- For rinse-off, the reference gives 2–4% in this reference.
The water phase is the addition point for Glycerin; a separate melt is unnecessary.
4. Sources réglementaires et conformité mondiale
- A CosIng entry naming Glycerin does not by itself approve the purchased grade or complete cosmetic.
- EU market placement under Regulation (EC) No 1223/2009 requires an assessment of the safety of the final cosmetic containing Glycerin for the completed formula, not simply for an ingredient in isolation.
- 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 should not be read as a drug authorization or OTC listing and patch and stability testing remain part of finished-product review.
6. Stabilité et conditionnement
Protect the sealed bulk from heat, sun, and unnecessary exposure; for oxidation-sensitive formulas, consider an airless or pump pack; check the final package and formula together for compatibility and stability.
7. Formulations d'allégations (à faire / à éviter)
- The cosmetic concept for Glycerin in this entry centers on humectant function.
- The formulation note does not establish drug or therapeutic claims, clinical cures, or certification claims not confirmed for the product.
- This reference for Glycerin does not demonstrate whitening effects, acne treatment, antiperspirant performance, sunscreen protection, or hair growth.
