The substances are corrosive to the eyes and irritating to the skin. Basically the same safety measures for QUAB 188 and QUAB 151 apply to the QUAB Specialties.
QUAB 342, QUAB 360 and QUAB 426 are toxic to fish. Precautions must therefore be taken to prevent this product and its by-products from entering the aquatic environment.
The QUAB specialty products have not only cationic but also surface-active properties which are attributable to the long-chain alkyl groups. The dodecyl, cocoalkyl or stearyl groups lend hydrophobic (lipophilic) properties to the polymers modified by these QUAB reagents. This may cause foam formation when aqueous solutions are handled, particularly if there is strong mechanical agitation.
