Conclusion on classification

Terpinolene monoconstituent is an organic monoconstituent substance. It is very slightly soluble in water (4.6 mg/L according to the column elution method, 7 mg/L according to the slow-stirring method).

The short-term toxicity of terpinolene monoconstituent to aquatic organisms was investigated according to OECD guidelines and GLP. The following toxicity values are available for the substance:

Fish Acute: 96h-LC50(96 h) = 0.805 mg/L (based on geometric measured concentrations)

Aquatic invertebrates: EC50(48 h)= 0.634 mg/L (based on geometric measured concentrations)

Algae: ErC50(72 h)= 0.692 mg/L (based on geometric measured concentrations)

The lowest acute aquatic toxicity values based on available data ranges between 0.1 and 1.0 mg/L. There are no adequate chronic toxicity data available.

The degradation of terpinolene monoconstituent was investigated:

A reliable study was carried out according to OECD Guideline 301D and GLP. Under the conditions of this study, terpinolene monoconstituent was found readily biodegradable (81% of biodegradation on Day 28 based on oxygen consumption).

Information on bioaccumulation potential of the submission substance:

No fish BCF is available. log Kow is 4.33, which indicates a potential for bioaccumulation.

CLP Classification (Regulation (EC) No 1272/2008)

Acute aquatic hazard:

Terpinolene monoconstituent is classified under CLP Regulation for acute toxic hazard - Category 1. The lowest EC50 value (Daphnia magna) ranges between 0.1 and 1 mg/L.

Chronic aquatic hazard:

Terpinolene monoconstituent is classified under CLP Regulation for chronic toxic hazard - Category 1. The lowest acute EC50 value (Daphnia magna) ranges between 0.1 and 1 mg/L. The substance is readily biodegradable but log Kow > 4).

M-Factor: 1.

DSD Classification (Directive 67/548/EEC)

Terpinolene monoconstituent is classified dangerous for the environment: N; R50/53. The lowest acute EC50 value (Daphnia magna) ranges between 0.1 and 1 mg/L. The substance is readily biodegradable substance but log Kow > 3.
