Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 105 (Water Solubility)
Deviations:
yes
Remarks:
adjustments of equilibration temperature and time to assure accurate results for the sample.
GLP compliance:
no
Type of method:
flask method
Specific details on test material used for the study:
Cola®Teric CDB (INCI: Cetyl Betaine) is a liquid material comprising 30% w/w active surfactant with about 6% w/w associated salt and 64% w/w water.
Samples were mixed with water, equilibrated at 35°C for one week, and then checked for dissolved content. To assure full dissolution in the liquid portion of the sample, extended equilibration time at temperature was used.
Key result
Water solubility:
>= 44.26 - <= 44.7 other: wt%
Conc. based on:
test mat.
Incubation duration:
1 wk
Temp.:
25 °C
pH:
>= 4.6 - <= 4.7

Description of key information

Cetyl betaine is readily soluble in water.

Key value for chemical safety assessment

Water solubility:
444.8 g/L
at the temperature of:
25 °C
