  • PROCEDURE FOR DETECTING MICROBIAL CONTAMINATION BY BIOLUMINESCENCE IN ASSOCIATIVE ACRYLIC THICKENERS AND PRODUCTS CONTAINING THEM
    Publication number: 20100112611
    Abstract: A procedure for detecting microorganisms by bioluminescence in an aqueous formulation containing an ASE or HASE-type polymer, which implements at least one step of dilution of the aqueous formulation. This dilution step, and notably the regulation of the dilution factor, allows the bioluminescence technique, up to now ineffective on this type of products, to be implemented. It can henceforth be used on these ASE or HASE-type polymers, but also on products containing them, such as a paper coating, paint, lacquer, varnish or stain.
