1. INCI y CAS

INCI: Glycerin · CAS: 56-81-5

2. Función en la fórmula

The reference uses glycerin as a polyol humectant across washes, gels, and emulsions. Treat the percentage as development guidance.

3. Niveles de uso típicos (guía de formulación)

• For gels and serums, use 3–8% for the formula.
• The creams use-level reference is 2–5% in this reference.
• The rinse-off use-level reference is 2–4% for the formula.

The water phase is the addition point for Glycerin; a separate melt is unnecessary.

4. Fuentes normativas y cumplimiento global

• If Glycerin appears in CosIng, its entry is informational and does not approve a specific grade or finished cosmetic.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires the final cosmetic with Glycerin to undergo a safety assessment as part of the finished cosmetic's safety documentation.
• Check the supplier's technical information for the Glycerin grade and confirm the relevant market filing list.

5. Seguridad y evaluación de riesgos

This formulation note gives a cosmetic-use reference level; it does not establish drug approval or OTC-monograph status and the final formula should undergo patch and stability assessment.

6. Estabilidad y envasado

For bulk storage, avoid warmth and direct sun and keep the container closed; if the formula is oxidation-sensitive, an airless or pump format may be considered; use batch testing to verify stability and package compatibility.

The use-level note is a reference for cosmetic formulation; the listed level does not itself confer drug or OTC status so the finished cosmetic should receive patch and stability checks.

6. Estabilidad y envasado

7. Redacción de alegaciones (permitido / no permitido)
