Date of event: unknown.The date received by manufacturer has been used for this field.Results: four units were received for evaluation.Our quality engineer visually inspected the returned units and confirmed the presence of clear liquid drops along the roofs of the syringe barrels.The engineer identified the foreign as most likely being excess silicone.Conclusion: silicone is an inert, nontoxic medical substance used as a lubricant for disposable hypodermic products.It does not present a safety or efficacy issue nor does it impact product function.The silicone application process is designed to provide an even distribution of silicone on the interior of the syringe barrel.Then, when the plunger is fully depressed, the silicone gets distributed along the barrel roof and walls, ensuring a lubricated surface for the plunger to move against.However, in this case, there was an unusual aggregation of silicone on the barrel roof area which created the noticeable appearance.(b)(4).
