Which is better titanium dioxide or zinc oxide?
Titanium dioxide is effective at blocking UV-B and short-wave UV-A rays, but it is less effective than zinc dioxide at blocking long UV-A rays. Zinc oxide’s ability to block various types of rays makes it one of the most effective sun protection products on the market at preventing sun damage.
How is urotropine used in molecular recognition studies?
Urotropine is a convenient molecular scaffold in the formation of linear to macrocyclic supramolecular assembly with designed phenolic substrates based on both conventional O–H⋯N and unconventional C–H⋯O hydrogen bonds in molecular recognition studies. 1. Introduction
Why is urotropine not allowed in water resources?
production of urotropine usually contains residual amounts of urotropine, ammonia, formaldehyde, formic acid and methanol. Urotropine must be considered as a real wastewater pollutant and should not be allowed to enter water resources and soils because its molecule has a cyclic symmetric structure (Fig. 1) and is very stable.
Which is the best form of urotropin to use?
Urotropin is issued in the form of powder, tablets or solution for injections with various content of active agent. Drug can be packaged in bottles, ampoules or packages. Drug possesses considerable antimicrobic and antiinflammatory action.
