Additional information

Classification Justification for Reaction mass of 4-methoxyphenol and 4-methoxy-cyclohexanone and 4-methoxy-cyclohexanol (EC 947-389-1; Mochon roh):

According to the REACh ‘Guidance on the Application of CLP Criteria’, Part 4 (ECHA; June 2015) the classification of a mixture is to be based on the available information on the relevant components, if no or inadequate test data on the mixture itself are available and bridging principles based on similar tested mixtures are not applicable. According to REACh ‘Guidance on the Application of CLP Criteria’, Part 4 section 4.1.4.7. (ECHA; June 2015) a straightforward application of the summation method has to be used for the classification of a mixture, when classification data are available for some or all relevant components of the mixture.

The ‘Reaction mass of 4-methoxyphenol and 4-methoxy-cyclohexanone and 4-methoxy-cyclohexanol)’ is a mixture (EC 947-389-1; Mochon roh) that consists of the following three components:

- 4-Methoxycyclohexanol (C7H12O2; CAS 13482-23-0, Mochon): 70% (>65% to < 75%)

No harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI;

CLP self-classification: not to be classified

- 4-Methoxycyclohexan-1-ol(C7H14O2; CAS 18068-06-9): 20% (>15% to < 25%)

No harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI;

CLP self-classification: data not sufficient for classification purposes

- 4-Methoxyphenol (C7H8O2; CAS 150-76-5): 10% (>5% to < 15%)

No harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI;

CLP self-classification: chronic 3

Valid test data on the mixture as a whole (for all three trophic levels) are not available. Furthermore, there are no valid test data on similar tested mixtures available, meaning that any bridging principle cannot be used. Therefore, classification should be considered based on the available data of the individual components using the summation method, in accordance with REACh ‘Guidance on the Application of CLP Criteria’, Part 4 section 4.1.4.7. (ECHA; June 2015):

 

‘Reaction mass of 4-methoxyphenol and 4-methoxy-cyclohexanone and 4-methoxy-cyclohexanol’ - Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1, none of the relevant components as well as the mixture as a whole (EC 947-389-1; Mochon roh) are classified as hazardous to the environment.

According to Regulation (EC) 1272/2008 Annex VI Table 3.2, none of the relevant components as well as the mixture as a whole (EC 947-389-1; Mochon roh) are classified as hazardous to the environment.

 

‘Reaction mass of 4-methoxyphenol and 4-methoxy-cyclohexanone and 4-methoxy-cyclohexanol’ - Self-classification

Following GHS/CLP (summation method), the ‘Reaction mass of 4-methoxyphenol and 4-methoxy-cyclohexanone and 4-methoxy-cyclohexanol)’ (EC 947-389-1; Mochon roh) is not to be classified as acutely hazardous to the aquatic environment. Furthermore, the mixture is not to be classified as chronically hazardous to the aquatic environment.

 

Rationale:

The mixture as a whole (EC 947-389-1; Mochon roh) is not to be classified as acutely hazardous to the aquatic environment, since none of the relevant components is classified as ’Acute 1’.

 

The mixture as a whole (EC 947-389-1; Mochon roh) is not to be classified as chronically hazardous to the aquatic environment. The classification is based on the available classification data on the relevant components. One component is self-classified as chronic 3; the sum of the concentrations (in %) of all components classified as chronic 3 is < 25%:

- 4-Methoxyphenol (C7H8O2; CAS 150-76-5): 10% (>5% to < 15%)

 

Atmospheric compartment

None of the relevant components of the mixture (EC 947-389-1; Mochon roh) is listed in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.

None of the relevant components does belong to the greenhouse gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and in Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.
