WHO Technical Report Series, No. 937, 2006. Annex 4, Validation
4.1.4 Cleaning procedures for products and processes which are very similar do not need to be individually validated. A validation study of the “worst case” may be considered acceptable (bracketing)
4.1.6 Bracketing by product should be done only when the products concerned are similar in nature or property and will be processed using the same equipment. Identical cleaning procedures should then be used for these products.
4.1.7 When a representative product is chosen, this should be the one that is most difficult to clean. In your case, this would be the product of the highest concentration.
Thanks very for reply… i will regard your recommendations.
