Cleaning Vitamin Residues
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?
Glassware and Utensils Came Out Coated In A Dry White Residue
Q: We are working with a lab washer in a compounding pharmacy application. We are using Detergent 8 to clean glassware and utensils. The glassware and utensils came out coated in a dry white residue. Can you please advise why this is happening with this detergent?
Do Enzymatic Detergents Disinfect?
Q. We have been using Tergazyme to clean lenses and cuvettes for our light scattering equipment and it works flawlessly! My question is: Does Tergazyme enzyme detergent have any disinfection properties, like killing of bacteria such as E. coli, or viruses?
Dilution Precision in Concentration Measurements
Q. Do I determine detergent dilution by weight or by volume or both?
A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions. In manufacturing situations, often directions are written volume/volume or volume/weight.
Cosmetics Cleaning: Removing Deodorant From Stainless Tanks
Q: How can we clean residual deodorant from our stainless steel tanks? It is proving very difficult. It is largely AlCl3.
A: Deodorant, designed to stay in place for obvious reasons, can be quite adherent on processing equipment. If it stays on skin for extended periods, which is designed to avoid residues, imagine what it does to stainless steel!
