Glycerin
Humectant
1. INCI & CAS
INCI: Glycerin · CAS: 56-81-5
2. Role in the formula
The reference uses glycerin as a polyol humectant across washes, gels, and emulsions. Treat the percentage as development guidance.
3. Typical use levels (formulation guide)
- Gels and serums may use the guide range 3–8% for the formula.
- For creams, use 2–5%.

The guide places Glycerin in the water phase and calls for no melt step.
4. Regulatory sources & global compliance
- The CosIng record for Glycerin, where listed, is informational rather than product-specific authorization.
- For a cosmetic sold in the EU, Regulation (EC) No 1223/2009 requires a safety review of the finished cosmetic in which Glycerin is used rather than for an ingredient name alone.
- Establish grade-specific details for Glycerin from the supplier and assess filing requirements in the intended market.
5. Safety & risk assessment
This level is a cosmetic-formulation guide; it does not qualify a finished product as a drug or OTC product so assess patch response and stability in the final formula.
6. Stability & packaging
Keep the ingredient in cool, closed bulk storage away from sunlight; if the formula is oxidation-sensitive, an airless or pump format may be considered; confirm compatibility and stability using the selected formula and pack.

- This formulation entry does not demonstrate drug effects, cures, or certification claims that go beyond the documented ingredient information.
