Additional information
Justification for classification or non-classification
Eye and/or skin irritation studies are available on hydrogenated castor oil, ‘fatty acids, castor oil hydrogenated’ and stearic acid. These studies suggest that 12-hydroxystearic acid is likely to be not or only minimally irritating to skin and eyes.
Exposure to 12-hydroxystearic acid via the inhalation route and consequent respiratory irritation is not expected given it low vapour pressure and solid form (flakes). Appropriate risk management measures are implemented wherever necessary (e.g. dustproof masks). Moreover, the absence of any significant skin or eye irritation does not suggest 12-hydroxystearic acid to be a respiratory irritant.
Based on the available data, this substance does not require to be classified for eye or skin irritation properties according to Directive 67/548/EEC or 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.
