Surface tension

Administrative data

Endpoint:

surface tension

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because water solubility is below 1 mg/L at 20°C

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

transformation / dissolution of metals and inorganic metal compounds

Type of information:

experimental study

Adequacy of study:

key study

Study period:

April 2022

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Series on Testing and Assessment No. 29 (23-Jul-2001): Guidance document on transformation/dissolution of metals and metal compounds in aqueous media

GLP compliance:

no

Type of method:

flask method

Specific details on test material used for the study:

Batch No.: OP.1501019

Type of test:

full transformation/dissolution test - metals and sparingly soluble metal compounds

Mean dissolved conc.:

< 0.01 mg/L

Element analysed:

Titanium

Loading of aqueous phase:

1 mg/L

Incubation duration:

7 d

Test conditions:

Temperature: controlled ambient temperature + 2 °C in the range 20 - 25°C.
The test was performed in closed vessels and in the dark.
Two time intervals were included in the test to determine the concentrations of dissolved Titanium oxide: after 7 days of incubation and after 28 days of incubation (end of the test).

Key result

Type of test:

full transformation/dissolution test - metals and sparingly soluble metal compounds

Mean dissolved conc.:

< 0.01 mg/L

Element analysed:

Titanium

Loading of aqueous phase:

1 mg/L

Incubation duration:

28 d

Test conditions:

Temperature: controlled ambient temperature + 2 °C in the range 20 - 25°C.
The test was performed in closed vessels and in the dark.
Two time intervals were included in the test to determine the concentrations of dissolved Titanium oxide: after 7 days of incubation and after 28 days of incubation (end of the test).

Conclusions:

The transformation/dissolution in aqueous media test performed on the test item showed a concentration lower than LOQ of 0.010 ppm. In conclusion, the substance is considered not soluble in water, even after 28 days.
