Additional information

The PNEC values were determined for the substance itself by application of methods provided in ECHA Guidance Chapter R.10 (May 2008).

Conclusion on classification

Neryl acetate is an organic mono-constituent substance and is slightly soluble in water (34.51 mg/L at 20°C).

The following short-term toxicity are available for the substance.

Fish Acute: 96h-LC50 = 6.0 mg/L

Aquatic invertebrates: 48h-EC50 = 9.97 mg/L

Algae: 72h-ErC50 = 4.9 mg/L

The lowest acute aquatic toxicity value based on available data ranges between 1 and 10 mg/L. The long-term toxicity of the registered substance to aquatic organisms was not investigated. Thus, there are no adequate chronic toxicity data available.

The degradation of the substance was not investigated because a read-across from nerol was used. A reliable study carried out according to Guideline OECD 301D and GLP was available on nerol. Nerol was found readily biodegradable. Therefore, by extrapolation, neryl acetate can be considered as readily biodegradable in aquatic system.

Information on bioaccumulation potential of the submission substance:

No fish BCF is available. log Kow is 3.98 which indicates no potential for bioaccumulation.

CLP Classification proposal:

It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).

Acute aquatic hazard: not classified. Reasoning: lowest E(L) C50 higher than 1 mg/L.

Chronic aquatic hazard: not classified. Reasoning: adequate chronic toxicity data are not available, lowest acute E(L) C50 value ranges between 1 and 10 mg/L, rapidly degradable substance with a log Kow < 4.
