Reference
Name:
Dextro alpha fenchyl alcohol
Type of composition:
legal entity composition of the substance
State / form:
solid: bulk
Reference substance:
Composition 1
PBT status:
the substance is not PBT / vPvB
Justification:

Persistence Assessment

Evidence of ready biodegradation:

Study report: The substance is biodegradable (study performed according to OECD Guideline 301F).

The substance is not fulfilling the criteria for Persistence (P)

Bioaccumulation Assessment

The log Kow value of the substance is lower than 4.5: calculated log Pow of the substance is 2.93 (study performed according to OECD Guideline 107).

The substance is not fulfilling the criteria for Bioaccumulation (B)

Toxicity Assessment

There is no long-term toxicity studies available with fish and daphnia.

- Short-term toxicity to fish: Key study: LC50 (96h) = 59 mg/L (based on mortality) (read-across from supporting substance L-borneol).

- Short-term toxicity to aquatic invertebrates: Key study: EC50 (48h) = 11.67 mg/L (based on mobility, without pH adjustment) (read-across from analogue substance Dextro alpha fenchyl acetate).

- Toxicity to aquatic algae: Key study: EC50 (72h) = 9.19 mg/L and NOEC (72h) = 2.63 mg/L (based on growth rate, with pH adjustment) (read-across from analogue substance Dextro alpha fenchyl acetate)

There is no evidence of CMR.

Not classified for specific target organ toxicity after repeated exposure.

The substance is not fulfilling the criteria for Toxicity (T)

Summary and overall Conclusions on PBT or vPvB Properties

D-alpha fenchol is not a PBT or vPvB substance.
