Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
1981
Deviations:
no

Type of method:
OECD harmonised ring method
Key result
Surface tension:
69.9 mN/m
Temp.:
21 °C
Conc.:
90 other: % saturation

Calibration factor based on measurement with water

A) Measured value of the surface tension of water : 69.5 mN/m

B) EC / OECD standard reading for surface tension of water: 72.3 mN/m

Resulting calibration factor (B/A): 1.04

According to OECD 115, in addition to the calibration factor based on water, a correction based on the Harkins-Jordan correctionwas performed (tabulated values within OECD 115).

Conclusions:
Surface tension (OECD 115): 69.9 mN/m at 21°C (90% saturation)
Executive summary:

The surface tension of 1-chloro-2,3-dimethylbenzene was detemined with the ring-method according to OECD 115 (1981) compliant with GLP.

A saturated solution in water was produced by 90 min of vigorous shaking and phse separation. The solution was diluted with water to 90% saturation and measurements performed at 21°C.

Two replicate measurements were performed with the following results (calibrated using water; corrected based on Harkins-Jordan):

1) 69.9 mN/m

2) 69.9 mN/m

Final result:

Suface tension of 1-chloro-2,3-dimethylbenzene in water (90% saturation, 21°C): 69.9 mN/m.

Based on a surface tension of water of 72.3 mN/m at 23°C the substance is not surface active.

Description of key information

Surface tension (OECD 115): 69.9 mN/m at 21°C (90% saturation, ca. 18 mg/L based on key result for solubility in water)

Key value for chemical safety assessment

Surface tension:
69.9
