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
Justification for type of information:
From the structural formula Musk R1 is not expected to react significantly with water at 20°C, and will in no way emit flammable gases. This is in line with the fact that during studies such as the determination of the water solubility of Musk R1 (Water solubility of Musk R1, Givaudan Study 17-E096) no reaction of Musk R1 with water was observed.
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 and observations during testing.
GLP compliance:
no
Interpretation of results:
not classified based on GHS criteria
Conclusions:
From the structural formula Musk R1 is not expected to react significantly with water at 20'C, and will in no way emit flammable gases. This is in line with the fact that during studies such as the determination of the water solubility of Musk R1 (Water Solubility of Musk R1, Givaudan Study 17-E096) no reaction of Musk R1 with water was observed.
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 Musk R1 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
Endpoint:
flammable liquids: obsolete as covered by section 'Flash point'
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Reason / purpose for cross-reference:
data waiving: supporting information
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 (IUCLID section 4.1) with a freezing point of 34 °C (see IUCLID section 4.2), so the substance should not be classified as a flammable solid.
Reason / purpose for cross-reference:
data waiving: supporting information

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 (gases) 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), 166°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) with a freezing point of 34 °C (see IUCLID section 4.2), so the substance should not be classified as a flammable solid, and with a low vapour pressure of 0.5 Pa at 25 °C (see IUCLID section 4.6), so the substance should not be classified as a flammable gas.
