Dyneema Â® SK60 is the only super-fiber with a density below 1.0 (the fiber can float on water). The specific gravity of Dyneema Â® SK60 is 0.97, which is the lowest value among super fibers and is lighter than water.
Benzalkonium chloride is a quaternary ammonium compound and is used as a preservative in many ophthalmic solutions. Typically in dilutions of 0.01% or less.lkyl triethanol ammonium chloride, benzethonium chloride, CETRIMIDE (cetyltrimethylammonium bromide), DYMED and POLYQUAD are also examples of quaternary ammonium compounds that are used in ophthalmic preparations.
For our purposes, more technically, the specific kind of chlorine compound used in liquid disinfectants is known as sodium hypochlorite, which is found in household bleach. Besides chlorine, another well-known category of disinfectants is known as quaternary ammonium compounds.Keep in mind, that chlorine can work equally well in different types of water hardness. This is not the case for quaternary ammonium compounds, whose capability to disinfect suffers with increasing water hardness.amely, quaternary ammonium compounds can kill off enveloped viruses much better than non-enveloped viruses. You can liken a non-enveloped virus to one that has a hardy shell, like a nut, around its nucleic acid genome. An enveloped virus is surrounded by a thin membrane, kind of like a thin balloon.
