25 °C

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.
