Glycerin
Humectant
1. INCI & CAS
INCI: Glycerin · CAS: 56-81-5
2. Role in the formula
The listed glycerin role is that of a polyol humectant in cosmetic washes, gels, and emulsions; the amount is guidance only.
3. Typical use levels (formulation guide)
- 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. Regulatory sources & global compliance
- 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. Safety & risk assessment
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. Stability & packaging
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. 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 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.
