The target substance is a hydrolytically unstable organozirconate with hydrolysis half-life less than 5 minutes (Borica, 2016). The identified hydrolysis products include 1 -propanol and zirconium dioxide, which is an inorganic substance.
Zirconium dioxide is a solid precipitate which is not classified as hazardous to human health or to the environment. As an insoluble precipitate, it is also lacking bioavailability, and therefore not relevant to be considered further in CSA.
On the basis the rapid hydrolysis, the intrinsic properties lie in the degradation products.
Biodegradation & Bioaccumulation The organic component of the hydrolysis product - 1 -propanol was found readily biodegradable (Price, et. al. 1974) and highly water soluble. Bioaccumulation is not expected.
