Humectant
1. INCI & CAS
INCI: Glycerin · CAS: 56-81-5
2. Role in the formula
The glycerin note covers its polyol-humectant role in washes, gels, and emulsions and gives a formulation guide level.
3. Typical use levels (formulation guide)
- For gels and serums, the recorded level is 3–8% in this reference.
- For creams, use 2–5%.
- The rinse-off use-level reference is 2–4% in this reference.
Add Glycerin to the water phase; no separate melt step is needed.
4. Regulatory sources & global compliance
- A CosIng listing for Glycerin provides ingredient information, not approval of a supplied grade or finished product.
- The finished-product provisions of Regulation (EC) No 1223/2009 require a safety assessment covering the complete formulation with Glycerin as part of the finished cosmetic's safety documentation.
- Review the documentation for the actual Glycerin grade and the filing requirements for the target market.
5. Safety & risk assessment
Treat the listed amount as cosmetic-development guidance; it makes no claim of drug or OTC authorization and the finished formula still needs patch and stability testing.
6. Stability & packaging
Use cool, sealed storage away from strong light for the bulk; take oxidation sensitivity into account when selecting the final pack; confirm stability and pack fit with the final formula.
7. Claims language (Do / Don’t)
- For cosmetic use, this entry records Glycerin in a direction centered on humectant function.
- The cosmetic listing provides no basis for therapeutic effects, curative outcomes, or unsupported certification statements.
- This guide to Glycerin does not establish whitening effects, acne treatment, antiperspirant performance, sunscreen protection, or hair growth.
