1. INCI & CAS

INCI: Urea · CAS: 57-13-6

• Use CosIng's information on Urea as a reference, then verify the specific grade and intended use under market rules.
• EU cosmetics rules under Regulation (EC) No 1223/2009 require a safety evaluation of the product containing Urea as it will be marketed rather than for an ingredient name alone.
• Verify the purchased Urea grade using supplier data, alongside the applicable filing rules for the destination market.

5. Safety & risk assessment

Use the stated level as reference guidance for cosmetic formulation; the listed level does not itself confer drug or OTC status and the completed formula still requires stability and patch testing.

• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires the complete cosmetic containing Lactic Acid to receive its own safety assessment as a finished-product assessment.
• Verify the purchased Lactic Acid grade using supplier data, alongside the applicable filing rules for the destination market.

5. Safety & risk assessment

The listed use rate is intended as a cosmetic-development guide; this reference is not approval for drug use or OTC marketing while finished-product patch and stability testing remain necessary.

6. Stability & packaging

Keep bulk material sealed, cool, and out of direct sunlight; review airless or pump options if oxidation presents a concern; use batch testing to verify stability and package compatibility.

• Review the supplier TDS for the received Glycerin grade, together with the target market's current filing requirements.

5. Safety & risk assessment

Use the stated level as reference guidance for cosmetic formulation; it provides no evidence that a drug or OTC monograph applies and the completed cosmetic needs its own patch and stability checks.

6. Stability & packaging

Protect the sealed bulk from heat, sun, and unnecessary exposure; consider an airless or pump format when oxidation sensitivity warrants it; check the final package and formula together for compatibility and stability.

• The development record is not evidence of claims of drug action or cure, or a product certification outside the supporting records.
