Conclusions:

Sw of (D,L)-limonene is 2.65 mg/L. Thereofre the substance is considered as slightly soluble.

Executive summary:

Water Solubility, Sw, of the substance (D,L)-limonene (CAS# 138-86-3), has been calculated by the model i-SAFERAT Toolbox, Linear v.1.1. Calculation was performed from the input Molecular Weight of (D,L)-limonene, and (D,L)-limonene falls inside the Applicability Domain of the model.

Therefore, the Sw value of (D,L)-limonene is 2.65 mg/L. (D,L)-limonene is considered as slightly soluble.

Description of key information

The Water Solubility of Eucalyptus oil was calculated from data on its major constituents.

Key value for chemical safety assessment

Water solubility:

1.82 mg/L

Additional information

In a weight-of-evidence approach, 1,8-cineol water solubility data has been gathered (public reference). (D,L)-limonene, α-pinene and β-pinene values were calculated with iSAFERAT Toolbox, Linear, v1.1. These 3 components fall inside the Applicability domain of the model. All the available results on isomeric constituents were very similar. Therefore, the key value for the multi-constituent has been set as the lowest value of 1.82 mg/L. Indeed, at this concentration, it is supposed that the constituents are present at the same ratio as in the composition of the multi-constituent substance.

Water Solubility, Sw of (d,l)-limonene= 2.65 mg/L

Water Solubility, Sw of alpha-pinene= 1.82 mg/L

Water Solubility, Sw of 1,8-cineol= 3500 mg/L
