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)
- Formulation guidance for gels and serums: 3–8% in this reference.
- 2–5% is listed for creams as a formulation guide.
- For rinse-off, use 2–4% as a formulation guide.
The guide places Glycerin in the water phase and calls for no melt step.
4. Sources réglementaires et conformité mondiale
- Use CosIng's information on Glycerin as a reference, then verify the specific grade and intended use under market rules.
- For an EU-market product, Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Glycerin rather than for an ingredient name alone.
- Review the supplier TDS for the received Glycerin grade, together with the target market's current filing requirements.
5. Sécurité et évaluation des risques
The listed use rate is intended as a cosmetic-development guide; it is not evidence of drug approval or OTC authorization so patch response and stability should be checked on the finished product.
6. Stabilité et conditionnement
Keep the bulk container closed and shaded in a cool area; review airless or pump options if oxidation presents a concern; check the finished batch's stability and package compatibility.
7. Formulations d'allégations (à faire / à éviter)
- The cosmetic formulation concept for Glycerin centers on humectant function.
- The cosmetic listing is not evidence of therapeutic results, cure claims, or unverified certification claims.
- This reference for Glycerin should not be used to substantiate whitening, treatment of acne, perspiration control, sun protection, or hair growth.
