Urea
Keratin-softening humectant
1. INCI y CAS
INCI: Urea · CAS: 57-13-6
2. Función en la fórmula
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. Niveles de uso típicos (guía de formulación)
- For lotions, the recorded level is 2–5%.
- The stated reference for foot and heel creams is 5–10%.
- The level shown for gels is 3–8% in this reference.
Dissolve into water. Urea can drift pH; set the finished pH after addition.
4. Fuentes normativas y cumplimiento global
- A CosIng entry naming Urea does not by itself approve the purchased grade or complete cosmetic.
- EU cosmetics rules under Regulation (EC) No 1223/2009 require a safety assessment of the finished cosmetic containing Urea rather than for an ingredient name alone.
- Establish grade-specific details for Urea from the supplier and assess filing requirements in the intended market.
5. Seguridad y evaluación de riesgos
The use-level note is a reference for cosmetic formulation; the listed level does not itself confer drug or OTC status so patch response and stability should be checked on the finished product.
6. Estabilidad y envasado
Protect the sealed bulk from heat, sun, and unnecessary exposure; evaluate packaging against the formula's susceptibility to oxidation; confirm stability and pack fit with the final formula.
7. Redacción de alegaciones (permitido / no permitido)
- The formulation note describes Urea as part of a cosmetic direction focused on urea softening.
- This reference is not evidence of drug effects, clinical cures, or unsupported product certifications.
- The formulation record for Urea should not be used to substantiate a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.
