Glycerin
Humectant
1. INCI & CAS
INCI: Glycerin · CAS: 56-81-5
2. Role in the formula
For emulsions, gels, and washes, this guide assigns glycerin a polyol-humectant role. Its level is not a batch assay.
3. Typical use levels (formulation guide)
- For gels and serums, the recorded level is 3–8% as a formulation guide.
- The formulation record indicates 2–5% for creams.
- 2–4% is listed for rinse-off in this reference.
Add Glycerin in the water phase without melting it first.
4. Regulatory sources & global compliance
- A CosIng entry naming Glycerin does not by itself approve the purchased grade or complete cosmetic.
- The EU Cosmetics Regulation (EC) No 1223/2009 requires a safety evaluation of the product containing Glycerin as it will be marketed before the cosmetic is placed on the EU market.
- Check the supplier's technical information for the Glycerin grade and confirm the relevant market filing list.
5. Safety & risk assessment
Read the recorded level as a cosmetic formulation guide; the note establishes neither drug approval nor OTC-monograph status with patch response and finished-product stability still to be verified.
6. Stability & packaging
Hold the bulk material in a sealed, cool place shielded from light; match the pack choice to the system's oxidation risk; verify the chosen pack against the tested formula.
7. Claims language (Do / Don’t)
- The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.
- The ingredient guidance does not demonstrate therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
- The ingredient record for Glycerin offers no support for a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.
