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.

Description of key information

Additional information

A grouping approach was used to describe the physical and chemical properties of the substance 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts (EC 939-457-4). For this aim, the structurally analogue substance 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-(C8-18(even numbered) acyl) derivs., hydroxides, inner salts (EC 939-455-3) was used as source substance.

The studies used for the grouping approach were performed on either dried commercial products (solid content = active content + minor constituents + impurities) or aqueous commercial products (the substance is manufactured in aqueous solutions and is never used in a solid form).

The grouping approach is built on the following similarities: general chemical process of manufacturing, functional groups, general composition and main constituent ( C12 alkylamidopropylhydroxysultaine). The main variable resides in the alkyl C-chain distribution.
