Urea
Keratin-softening humectant
1. INCI et CAS
INCI: Urea · CAS: 57-13-6
2. Rôle dans la formule
Cosmetic urea guides often use about 2–10% for softness and higher levels only when the brief and the destination rules allow. This page does not claim a drug keratolytic.
3. Niveaux d'emploi typiques (repère de formulation)
- The level shown for lotions is 2–5%.
- For foot and heel creams, the reference gives 5–10%.
- The stated reference for gels is 3–8% for the formula.
Dissolve in water. Urea can drift pH; set the finished pH after addition.
4. Sources réglementaires et conformité mondiale
- If Urea appears in CosIng, its entry is informational and does not approve a specific grade or finished cosmetic.
- The finished-product provisions of Regulation (EC) No 1223/2009 require a safety assessment of the complete cosmetic formula containing Urea for the completed formula, not simply for an ingredient in isolation.
- Confirm the actual Urea grade from supplier documentation and check requirements where the product will be sold.
5. Sécurité et évaluation des risques
The guide records a level for cosmetic formulation purposes; it does not authorize a drug or OTC product so assess patch response and stability in the final formula.
6. Stabilité et conditionnement
Keep the bulk container closed and shaded in a cool area; if oxidation risk calls for it, review a pump or airless format; verify the chosen pack against the tested formula.
7. Formulations d'allégations (à faire / à éviter)
- The recorded cosmetic positioning for Urea highlights urea softening.
- The formulation note does not support medical outcomes, cure language, or a product certification not supported by the available facts.
- The ingredient record for Urea should not be used to substantiate a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.
