Any other information on results incl. tables
The pH of pure surfactant at 0.1 g/L and 1 g/L in water was 5.6-6.2 based on 12 measurements. The pH of the commercial 28% solution was 10, due to the addition of NaOH.
Applicant's summary and conclusion
- Conclusions:
- The test substance is a neutral compound with a pH of 5.6-6.2.
- Executive summary:
The pH was measured “as is” with the temperature within 25±5°C. The pH of the surfactant in glycol solvent mixture and water was pH = 10 due to the addition of NaOH, while the pure surfactant is a neutral compound with a pH of 5.6-6.2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
