Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Minimally irritating.
Key value for chemical safety assessment
Additional information
Neodecanoic acid is minimally but transiently irritating to the skin and eyes.
In skin irritation studies, mild and transient erythema and edema are noted in animals. However, these reactions were fully reversible within 7 days post exposure. After, 7 days, desquamation was noted.
In eye irritation studies, 1 hour after treatment, animals typically show a slight redness of the conjunctivae, slight to moderate swelling and slight to moderate discharge. Recovery typically occurs within 48 hours after treatment and is fully resolved by 72 hours.
In a study to assess respiratory irritation, mice received 30 minute head only exposures to average actual concentrations of 3607 (group 1), 1098 (group 2), or 334 (group 3) mg/m3 of neodecanoic acid. The group 1 mean respiratory rate was depressed 42.5% below the pre-exposure rates, while the group 2 rate was decreased 24.9 %. The group 3 sample respiratory rate was increased by 7.9%. One of the group 1 mice died approximately 16 minutes after the start of the exposure. The three surviving mice displayed both sensory and pulmonary responses. Although a 50% reduction in respiratory rate was not achieved, a RD50 based on the three exposure groups was estimated as 5491 mg/m3.

Justification for classification or non-classification
No classification for skin/eye irritation or corrosion is indicated according to the general classification and labeling requirements for dangerous substances and preparations (Directive 67-548-EEC) or the classification, labeling, and packaging (CLP) 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.
