Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
For this endpoint, the read across between PWH/ammonium and PWH/sodium salt is valid, because this toxicological property is defined by the main component.The read across justification that takes into account the ammonium ion properties is attached on section 13 of the dossier.
An OECD 422 study has been conducted on Paraffin waxes and Hydrocarbon waxes C14-17, chloro, sulfochlorinated, low sulphonated, saponified setting a NOAEL = 30 mg/Kg . The minimal effect concentration has been set at 180 mg/kg bw, that for a 422 repeated dose test is not leading to classification for repeated dose toxicity. No study has been conducted for inhalatory and dermal repeated dose toxicity because exposure of humans via inhalation is unlikely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size and exposure of humans by dermal route is unlikely; physicochemical and toxicological properties don't suggest potential for a significant rate of absorption through the skin
Justification for selection of repeated dose toxicity inhalation - systemic effects endpoint:
Based on REACH regulation annex VIII column 2 (specific rules for adaptation from column 1) the study does not need to be conducted if exposure of humans via inhalation is unlikely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size.
Justification for selection of repeated dose toxicity inhalation - local effects endpoint:
Based on REACH regulation annex VIII column 2 (specific rules for adaptation from column 1) the study does not need to be conducted if exposure of humans via inhalation is unlikely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size.
Justification for selection of repeated dose toxicity dermal - systemic effects endpoint:
Based on REACH regulation annex VIII column 2 (specific rules for adaptation from column 1) the study does not need to be conducted if exposure of humans by dermal route is unlikely; physicochemical and toxicological properties don't suggest potential for a significant rate of absorption through the skin
Justification for selection of repeated dose toxicity dermal - local effects endpoint:
Based on REACH regulation annex VIII column 2 (specific rules for adaptation from column 1) the study does not need to be conducted if exposure of humans by dermal route is unlikely; physicochemical and toxicological properties don't suggest potential for a significant rate of absorption through the skin
Justification for classification or non-classification
According to CLP regulation (EC1272/2008) the substance is not classified for repeated dose toxicity.
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).
