Q: We are looking for detergent and process recommendations for manual cleaning of a 100 gallon mixer. We make one product in the mixer which contains water, modified food starch, acidic buffers, sucralose and preservative. Currently when cleaning, we boil for 1 hour at 90°C, then cool, drain and soak in cool water while using the mixing blades.  Scrub brushes and a spray hosing follows that. The mixer is made from stainless steel.

Q: Can you tell me if Liquinox can clean/remove pharmaceutical probiotics? We use this product to clean our packaging lines. We have a customer who is looking to have us package their probiotic product.

A: Liquinox® Critical Cleaning Liquid Detergent is an excellent emulsifier of organic and oily residues. It will do the job. Best practice, however, would be to incorporate a powerful emulsifier of organic and oily residues, along with enhanced protein removal.

We are cleaning a V Mixer made of NSF Stainless steel and we are using it to mix different protein powders, amino acids, and herbs for dietary supplements. It is small enough to be cleaned by hand but not small enough for any type of sink. I was advised to buy your Citranox product. Is that the best detergent for this job?

Q. We manufacture vitamins, which include minerals (calcium, magnesium etc.) and have found that Citranox is very effective in cleaning the residue left in our equipment. Unfortunately, we have learned that the pH of Citranox is too low for our local requirements. Do you have another detergent with a higher pH that would work equally as well?

Q. How do you remove protein out of pipes, centrifuges and tanks in a CIP environment with water temperatures averaging 20C?

A. In a cooler temperature environment, consider adding an enzymatic cleaner to your alkaline/acidic CIP routine. A product like Tergazyme® Enzyme-Active Powdered Detergent, which contains both protease and surfactants, is not only efficient at removing the biofilm, but will also slow down the formation of biofilm and allow the regular cleaning cycle to clean effectively for more cycles.

Q. Our pharmaceutical company is transferring product manufacture to a different one our facilities. We used a CIP cleaning process with Citrajet and are going to have to perform validation and verification tests again. What information do we need for our testing? Chemical properties might be helpful as well as the science on how this chemical works. We would also need information on disposal and the requirements for allowing this to flow to normal process drains.
