Applicant's summary and conclusion
- Conclusions:
- The viscosity of para-nonyl-ortho-cresol, branched was determined using a rotational viscometer to be 267 and 240 mPa * s at 25 °C for batches 2233-93-3 and PE-251548 respectively, and 25 and 11 mPa * s at 75 °C.
- Executive summary:
Para-nonyl-ortho-cresol, branched was analysed for its viscosity according to standard laboratory procedures using a rotational viscometer and conducted by an experienced and well trained lab technician.
The viscosity of para-nonyl-ortho-cresol, branched was determined to be 267 and 240 mPa * s at 25 °C for batches 2233-93-3 and PE-251548 respectively, and 25 and 11 mPa * s at 75 °C.
The entry is deemed to have a Klimisch Score of 4 as the methods are not described in detail.
