Reference
Description of key information
Cetyl Betaine is a surfactant containing both water soluble and oil soluble portions within its structure. It is known to be water soluble and partially soluble in n-octanol. This test has confirmed that this substance is n-octonol soluble at a level of 45.6% ± 0.7%.
The partition coefficient has been shown to be
Pow = 1.02
Log Pow = -0.0086
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.009
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
