PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Propylene glycol n-propyl ether does not have PBT or vPvB Properties.
Propylene glycol n-propyl ether meets the criteria for ready biodegradation, based on the results obtained in a DOC (dissolved organic carbon) Die-Away screening test according to OECD guideline 301A indicating 91.5 % degradation after 28 days (meeting the 10-day window).
Propylene glycol n-propyl ether has a low log Kow (log Kow < 1) and is readily biodegradable, which indicates that propylene glycol n-propyl ether offers little potential for bioconcentration in aquatic organisms.
Measured aquatic toxicity data indicate that propylene glycol n-propyl ether presents a low toxicity hazard to aquatic species. All EC50/LC50 values (fish, daphnia and algae) are greater than 100 mg/l.
Propylene glycol n-propyl ether is not classified as carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B), or toxic for reproduction (category 1A, 1B or 2) and there is no evidence of chronic toxicity, as identified by the classifications STOT (repeated exposure), category 1(oral, dermal, inhalation of gases/vapours, inhalation of dust/mist/fume) or category 2 (oral, dermal, inhalation of gases/vapours, inhalation of dust/mist/fume) according to Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
