    Cleaning Validation is the Methodology used to assure that a Cleaning Process removes Residues of the Active Pharmaceutical Ingredients (APIs) of the Product Manufactured on a piece of Equipment, the Cleaning Aids utilized in the Cleaning Process, and the Microbial Attributes so as to ensure that the process and processing Equipment are suitable for subsequent Pharmaceutical Manufacturing. Potential Contaminants include Residues of the APIs, API Degradation Species, or Residues from the Cleaning Process such as Detergents or Solvents.

    All Residues are removed to Predetermined levels so as to ensure that the Quality of the Next Product and that of the Future Products to be Manufactured is not compromised by Waste from the previous Product, to prevent Cross-Contamination and as a GMP Requirement. Acceptable Residue Limits (ARL) in Cleaning Validation is a Critical function and should be Practically Achievable, Verifiable for Logical Determination. This covers the Critical 10 ppm USP Limit Test on Materials for which no Toxicology Data is available.

    Validation of Cleaning Procedures is not normally required but a Risk Assessment should be performed to make sure that there is no potential for Degradation or Microbial Contamination that may adversely impact the Quality of the Product. The Analytical Methods for Cleaning Validation should be Validated & Suitable to Quantify at the Acceptance Criterion Level. The Limit of Detection (LOD) must be lower than or equal to the Acceptance Criterion Level. Blanks must be evaluated to ensure that there is no significant interference with the Recovery of the Analyte.

    EFRAC’s Cleaning Validation services include Validation of Cleaning Procedures, Challenge Tests for the Equipment Cleaning Process & Equipment specific Sampling through Visual inspection, Swab sampling or Rinse Sampling, Limit Tests to cover a range of Analyte Concentrations. The broad Cleaning Validation Sampling Techniques cover Swabbing, Rinsing & other appropriate or other Specific Techniques.
