Glycerin
Humectant
1. INCI e CAS
INCI: Glycerin · CAS: 56-81-5
2. Ruolo nella formula
This entry describes glycerin as a polyol humectant for gels, emulsions, and washes, with a guide level rather than a batch result.
3. Livelli d'uso tipici (guida di formulazione)
- Gels and serums: 3–8% for the formula.
- For creams, the reference gives 2–5% as a formulation guide.
- The stated reference for rinse-off is 2–4% as a formulation guide.
The water phase is the addition point for Glycerin; a separate melt is unnecessary.
4. Fonti normative e conformità globale
- An entry for Glycerin in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
- For an EU-market product, Regulation (EC) No 1223/2009 requires a safety assessment of the finished cosmetic containing Glycerin for the complete formula intended for sale.
- Review the supplier TDS for the received Glycerin grade, together with the target market's current filing requirements.
5. Sicurezza e valutazione del rischio
The use-level note is a reference for cosmetic formulation; the note establishes neither drug approval nor OTC-monograph status and the completed cosmetic needs its own patch and stability checks.
6. Stabilità e packaging
Use cool, sealed storage away from strong light for the bulk; choose a package with oxidation sensitivity in view; confirm final stability and pack compatibility on a representative batch.
7. Linguaggio dei claim (cosa dire / cosa non dire)
- The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.
- This reference provides no basis for therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
- This cosmetic entry naming Glycerin does not establish skin whitening, treatment of acne, sweat control, UV protection, or hair-growth results.
