Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 3,3'-iminodi(propylamine)
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- 3,3'-iminodi(propylamine)
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance is readily biodegradable based on an CO2 Evolution Test according to OECD 301B. After 28 days of exposure the degree of biodegradation was 89%. Therefore, the substance is not persisitent (not P/vP).
The measured log Kow (-1.25 at 25°C, BASF AG, 1989, report no. BRU 89.022) indicates no potential for bioaccumulation (not B/vB). In addition, BCF values were estimated to be 3.2 L/kg (BCFBAF v3.01, EPI Suite v4.11) and 0.07 L/kg (Bysshe, 1990). Measured read-across data for two structurally analogous substances support the estimated BCF values. In both studies performed according to OECD 305, the BCFs were found to be equal or lower than 6.3 L/kg (CAS 111 -40 -0) and lower than 5 L/kg (CAS 112 -24 -3) (NITE, 2011). Therefore, the substance is not bioaccumulative (not B/vB).
With respect to aquatic toxicity, the substance is "not T " since the lowest available chronic value is > 0.01 mg/L. Experimental chronic toxicity data are available only for algae (72 -h ErC10 > 100 mg/L, BASF AG 1989, report no. 01/0499/2/89) and aquatic invertebrates (21 -d NOEC = 5.6 mg/L, read-across from CAS 111 -40 -0, Akzo 1992, report no. CRL F91183). With respect to mammalian toxicity, the substance is "T", based on the self-classification as STOT-RE, target organ: thymus gland.
Therefore, with respect to all endpoints, the substance is "T".
In summary, the substance can be regarded as not PBT and not vPvB.
Reference
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).
