Aqueous Surface Disinfectant Contains pH Sensitive Colorant That Fades

US No. 12,116,554 B2 is awarded to Kinnos, a Brooklyn-based disinfection science company co-founded by Columbia University alumni.

US Patent No. 12,116,554 B2 (Jason Kang, Kevin Tyan, Katherine Jin); Kinnos Inc., based in Brooklyn, NY patented a method  or making a colorized solution of an aqueous disinfectant that is both stable in bulk solution and will fade to clear within a predetermined period of time after being applied to a surface, for example as a spray or film. The composition allows an end user to visualize both the extent of coverage and the duration of contact of the disinfectant with the surface, thereby providing more efficient disinfection of the surface.

The method entails mixing an oxidant-based disinfecting agent and a solid composition comprising a pH sensitive colorant, a surfactant and a rheology modifier. The pH sensitive colorant is present in an amount of from 1-10% w/w, based on the total weight of the composition. The total amount of surfactant is present in an amount of from 25-97% w/w, based on total weight of the composition.

Kinnos was co-founded by Columbia University alumni.
