Q&A Perchlorate-Free Detergents
Q) We are looking for a laboratory dishwasher detergent that does not contain perchlorates. One of our end users analyses for trace levels of perchlorates, so we cannot have a detergent that has that type of impurities.
A) Alconox’s detergents do not contain perchlorates. However, perchlorates can be a very trace contaminant in phosphate-containing detergents, even if the detergent does not have perchlorate as an ingredient.
Consequently, dilution to two orders of magnitude (usage concentration) and rinsing for another several orders of magnitude will very likely take this trace contaminant to well below detectable levels. Consequently, I would see no problem using any of Alconox’s aqueous detergents.
While Alconox’s detergents do not contain perchlorates as an ingredient, you can further avoid any such impurities (extremely trace or otherwise) by using its Solujet® Low-Foaming Phosphate-Free Liquid and Tergajet® Low-Foaming Phosphate-Free Detergent for your wash, depending on the washer’s need for a liquid concentrate or powdered cleaner, respectively.
For manual cleaning, utilising Liquinox® Critical Cleaning Liquid Detergent would be the way to go.
All of Alconox’s detergents have Certificates of Analysis, Certificates of Compliance and Trace Analysis Certificates available upon request.
