Reference 2

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Endpoint:

pyrophoric liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

Reference 4

Endpoint:

flammable solids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Description of key information

A study is scientifically unjustified, since hydrocarbons, C6-C7, n-alkanes, isoalkanes, cyclics, <5% n-hexane has a flash point below 23°C and an initial boiling point higher than 35°C and therefore meets the criteria of Category 2 for flammability.

Lower and upper flammability limits were extrapolated from existing literature data.

Additional information

In accordance with REACH Annex XI this study is scientifically unjustified. The flammability of liquids is determined on the basis of their flashpoint (in combination with their boiling point), their ability to emit flammable gases upon contact with water and their pyrophoricity. The molecular structure of the substance does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case. The flashpoint indicates that the substance is a Category 2 - Highly flammable liquid. The substance was placed in this hazard class because it has a flash point below 23°C and a initial boiling point higher than 35°C and therefore meets the criteria of Category 2 for flammability.

Justification for classification or non-classification

A study is scientifically unjustified, since Hydrocarbons, C6-C7, n-alkanes, isoalkanes, cyclics, <5% n-hexane has a flash point < 23°C and an inotial boiling point higher than 35°C and therefore meets the criteria of category 2 for flammability.
