- Reference substance:
- Reaction product of Titanium tetrakis(2-ethylhexan-1-olato) and pentane-2,4-dione
- Reference substance:
- Reaction product of Titanium tetrakis(2-ethylhexan-1-olato) and pentane-2,4-dione
- Reference substance:
- Reaction product of Titanium tetrakis(2-ethylhexan-1-olato) and pentane-2,4-dione
- Reference substance:
- Reaction product of Titanium tetrakis(2-ethylhexan-1-olato) and pentane-2,4-dione
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The target substance is hydrolytically unstable with hydrolysis half-life less than 30 minutes. Hydrolysis products include 2 -ethylhexanol, pentane-2,4 -dione and hydrated titanium dioxide. Titanium dioxide is an inorganic substance and consider not relevant for toxicity evaluation. The intrinsic short-, long-term toxicities of the target substance is based on the two organic hydrolysis products.
The ocatanol-water partition coefficients are 2.9 and 0.68 (log value) for the organic products. The target substance is therefore considered not persistent and no bioaccumulation potential.
Based on the lowest 72-h NOAEC (growth rate) Scenedesmus quadricauta of 2.0 mg/l, and no other findings of carcinogenicity, mutagenicity, toxicity to reproduction and long-term toxicity to target organs, the target substance is considered non-toxic.
