"CONCENTRATED LIQUID DISINFECTANT COMPOSITION, LIQUID DISINFECTANT CONCENTRATE, WORKING SOLUTION OF A BIOCIDENTALLY EFFICIENT DISINFECTANT, METHOD TO PROTECT A QUAT. DISABILITY QUAT. The present invention relates to a storage stable liquid disinfectant concentrate composition containing at least 1 wt% of a quat biocide. (biocidal active quaternary ammonium compounds) and capable of dilution with 20 parts water to 1 part concentrate to produce a dilute solution, the diluted solution exhibiting a MIC after 24 hours of up to 2% tryptone (or its equivalent protein) smaller than the MIC of a single solution of the same concentration of the same biocide quat. in water in the presence of the same protein concentration. The biocidal efficacy of biocide quat. may be protected by an activity protector selected from the group consisting of "enzyme stabilizers", "enzyme stabilizing systems", "micelle formation modifiers and inhibitors", and combinations thereof. The invention also relates to a disinfectant working solution prepared from the concentrate, and a method for protecting a quat biocide. of deactivation.
