What Annex V means for CITRIC ACID (AND) SILVER CITRATE

CITRIC ACID (AND) SILVER CITRATE is an approved preservative listed in Annex V of EU Cosmetics Regulation 1223/2009. Only substances on this positive list may be used as cosmetic preservatives in the EU.

Each preservative entry specifies maximum permitted concentrations and applicable product scope. Concentrations must not exceed the listed maximum. Some preservatives require warning statements on the product label.

This record is linked to 2 CosIng inventory ingredients for name and identifier cross-reference. The page also surfaces 12 related annex records with overlapping identifiers, annex logic or naming patterns.

Compliance checklist

  • Use concentration must not exceed: 0,2% corresponding to 0,0024% of silver
  • Verify the preservative is effective at the permitted concentration for your matrix.

Frequently asked questions

Yes. CITRIC ACID (AND) SILVER CITRATE is listed in Annex V of EU Cosmetics Regulation 1223/2009 as a permitted preservative. It may be used in cosmetics up to the maximum concentration specified above, within the permitted product scope.

CAS 5949-29-1; 77-92-9; 36701-38-9 is the unique numerical identifier assigned to CITRIC ACID (AND) SILVER CITRATE by the Chemical Abstracts Service. In cosmetic compliance work, the CAS number is used to cross-reference the substance across regulatory databases, raw material specifications and safety assessment reports. Multiple EU annex entries may share the same CAS number if the same substance appears under different conditions or in different annexes.

The maximum concentration of 0,2% corresponding to 0,0024% of silver applies to the concentration of the substance in the ready-to-use cosmetic product. When the substance is supplied as part of a blend or mixture, the calculation must account for the contribution of all sources in the formulation. The combined concentration must not exceed the stated limit.
