Reference

Reference 1

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Study period:

The study was conducted on 28 August 2017.

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

Reason / purpose for cross-reference:

data waiving: supporting information

Qualifier:

no guideline required

Principles of method if other than guideline:

Theoretical consideration, based on chemical structure of the components in the formulation.

GLP compliance:

no

Specific details on test material used for the study:

Not relevant (theoretical consideration based on chemical structure).

Interpretation of results:

not classified based on GHS criteria

Conclusions:

From the structural formula of its constituents, Oxyoctaline Formate can possibly react with water in a hydrolysis reaction to form a secondary alcohol and formic acid, both non gaseous. However, in studies such as the Hydroysis as a Function of pH (Oxyoctaline Formate: Determination of Adsorption Coefficient and Hydroysis as a Function of pH, Harlan Laboratories Ltd., Harlan Study Number 41400639) no significant reaction of Oxyoctaline Formate with water was observed, Oxyoctaline Formate did not emit flammable gases in contact with water.
Therefore it can be concluded beyond reasonable doubt that the contact of the substance with water or damp air will not lead to the development of dangerous amounts of gas or gases which may be highly flammable.

Executive summary:

It can be concluded beyond reasonable doubt that the contact of the substance Oxyoctaline Formate with water or damp air will not lead to the development of dangerous amounts of gas or gases which may be highly flammable.

Endpoint:

flammable gases

Data waiving:

study technically not feasible

Justification for data waiving:

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

Justification for type of information:

The substance is a liquid under standard conditions (IUCLID section 4.1, CSR section 1.3) with a low vapour pressure of 0.64 Pa at 25 °C (see IUCLID section 4.6, CSR section 1.3), so the substance should not be classified as a flammable gas.

Reason / purpose for cross-reference:

data waiving: supporting information

Reference 3

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

other:

Justification for type of information:

The substance is a liquid under standard conditions with a freezing point of -20 °C (see IUCLID section 4.2, CSR section 1.3), so the substance should not be classified as a flammable solid.

Description of key information

In accordance with annex XI of REACH flammability(solids) is not technically possible for this liquid substance.
In accordance with annex XI of REACH flammability(contact with air and water) is not necessary based on experience from safe handling and use

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Testing for this endpoint has been waived because the studies are scientifically unjustified. The substance is a liquid and the key value for flammability of liquids is the flash point.

Justification for classification or non-classification

According to Regulation (EC) 1272/2008, Annex I, section 2.6, "Flammable liquid means a liquid having a flash point of not more than 60 °C". The flash point (IUCLID section 4.11 , CSR section 1.3), 138°C, is higher than this value and so the substance should not be classified as a flammable liquid. The substance is a liquid under standard conditions (IUCLID section 4.1, CSR section 1.3) with a freezing point of < -20 °C (see IUCLID section 4.2, CSR section 1.3), so the substance should not be classified as a flammable solid, and with a low vapour pressure of 0.64 Pa at 25 °C (see IUCLID section 4.6, CSR section 1.3), so the substance should not be classified as a flammable gas.
