1. INCI et CAS
INCI: Glycerin · CAS: 56-81-5
2. Rôle dans la formule
The glycerin note covers its polyol-humectant role in washes, gels, and emulsions and gives a formulation guide level.
3. Niveaux d'emploi typiques (repère de formulation)
- For gels and serums, the recorded level is 3–8% in this reference.
- For creams, use 2–5%.
- The rinse-off use-level reference is 2–4% in this reference.
Add Glycerin to the water phase; no separate melt step is needed.
4. Sources réglementaires et conformité mondiale
- A CosIng listing for Glycerin provides ingredient information, not approval of a supplied grade or finished product.
- The finished-product provisions of Regulation (EC) No 1223/2009 require a safety assessment covering the complete formulation with Glycerin as part of the finished cosmetic's safety documentation.
- Review the documentation for the actual Glycerin grade and the filing requirements for the target market.
5. Sécurité et évaluation des risques
Treat the listed amount as cosmetic-development guidance; it makes no claim of drug or OTC authorization and the finished formula still needs patch and stability testing.
6. Stabilité et conditionnement
Use cool, sealed storage away from strong light for the bulk; take oxidation sensitivity into account when selecting the final pack; confirm stability and pack fit with the final formula.
7. Formulations d'allégations (à faire / à éviter)
- For cosmetic use, this entry records Glycerin in a direction centered on humectant function.
- The cosmetic listing provides no basis for therapeutic effects, curative outcomes, or unsupported certification statements.
- This guide to Glycerin does not establish whitening effects, acne treatment, antiperspirant performance, sunscreen protection, or hair growth.
