Non-specific methods for detecting residues of cleaning agents during cleaning validation

Abstract: Cleaning validation procedures are carried out in order to assure that residues of cleaning agents are within acceptable limits after the cleaning process. Cleaning agents often consist of a mixture of various surfactants which are in a highly diluted state after the water rinsing procedure has been completed. This makes it difficult to find appropriate analytical methods that are sensitive enough to detect the cleaning agents. In addition, it is advantageous for the analytical methods to be simple to perform … Show more

“…Yet the number of particles produced immediately following washing was similar for all three amounts, and for different amounts of flushing with clean water. This result indicates that only a small amount of residual detergent provides sufficient organic matter for particle formation and that the residue is not readily dislodged by tap water flushes (Milenovic et al., ; US EPA, ). Indeed, rinsing with nearly pure isopropyl alcohol did not eliminate the formation of new particles following washing with detergent.…”

“…23 Temizlik validasyonunun en önemli adımlarından biri de çıkarılacak kalıntı türü için uygun bir temizleme ajanının seçilmesidir. 24,25 Temizlik ajanlarının uygun seçimi daha kolay geçerlilik kazanan bir sistem geliştirmede yardımcı olmakta ve bu nedenle temizleme, validasyon çalışmalarını son derece basitleştirmektedir. Ayrıca, temizlik maddeleri ve parametrelerinin geçerliliği onaylandıktan sonra değiştirilmesi zordur.…”

“…Aksi takdirde farklı deterjanlar seçilmelidir. 14,24,26 Temizlik için bir deterjan kullanılıyorsa artıkları saptamaya çalışırken ortaya çıkabilecek zorluklar iyice belirlenmeli ve dikkate alınmalıdır. 25 Temizlik ajanı etkili bir şekilde ilaç-ürün kalıntısını ortadan kaldırmaktadır ancak kendi kalıntısını geride bırakırsa bir tür kirlilik diğeriyle değiştirilmiş olmakta ve ekipman etkin bir şekilde temizlenememektedir.…”
