Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Reference substance:
- SPA / Acrylsäure-(3-sulfopropyl)-ester, K-Salz
- Name:
- SPA / Acrylsäure-(3-sulfopropyl)-ester, K-Salz
- Type of composition:
- boundary composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- SPA / Acrylsäure-(3-sulfopropyl)-ester, K-Salz
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence asssessment:
Sulfopropyl acrylate (SPA) is not readily biodegradable in the aquatic environment (28% in 28 d) based on an OECD 301D (Mead, 2001). The ECHA guidance R7b states (ECHA 2014) “Biodegradation above 20% of theoretical (measured as BOD, DOC removal or COD) may be regarded as evidence of inherent, primary biodegradability”. Therefore, Sulfopropyl acrylate (SPA) may potentially fullfil the “P” or "vP" criterion. As the substance is not bioaccumulative further investigation of the “P” criterion is not considered necessary.
Bioaccumulation assessment:
Considering the low adsorption potential (log Kow = -3.63 at 21.5 °C, pH 7.5), the substance is not bioaccumulative.
Toxicity assessment:
As the substance is neither fulfilling the classification criteria for classification as R45, R46, R48, R49, R60-63, nor the screening criterion for Toxicity (T) to aquatic organisms stipulated in the ‘Guidance on information requirements and chemical safety assessment – Chapter R.11: PBT Assessment’ (ECHA, 2014), the substance does not meet the Toxicity (T) criteria.
