Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 701-208-0 | CAS number: -
Eye irritation
Administrative data
- Endpoint:
- eye irritation: in vivo
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Justification for type of information:
- See category justification attached in Section 13 for more information. Evaluating alkyl phenate sulfides (“phenates”) as a category is appropriate based on similar chemical structures and starting materials, manufacturing processes, physical and chemical properties, functional uses as a lubricating oil additive, and toxicological data. Regarding the ECHA Read-Across Assessment Framework (2017), the alkyl phenate category fit into Scenario 6 (different compounds with the same effect and no variation in the strength of that effect across substances).
Phenates in this category are manufactured in a similar way and from the same staring alkylphenol, tetrapropenyl phenol (“TPP”, EC 310-154-3; AKA phenol, dodecyl-, branched (PDB, PDDP)). The primary difference among the phenates is if they have calcium carbonate basing; the amount of overbasing may also differ. However, based on the trends observed with the robust toxicology data for the category, the amount of calcium carbonate overbasing is not expected to alter the hazards, especially as the core phenate functionality does not change and calcium carbonate has a low hazard potential.
Based on the data and consistent trends observed among category members, phenates have low hazard for human health and the environment. The registered (target) substance, EC 701-208-0 is very similar to EC 701-251-5 and this substance can be used as direct read across (and is used as the test material in the target record, where data exists for this source substance); EC 701-249-4 and 272-388-1 serve to bracket EC 701-208-0 with EC 701-251-5 regarding different levels of calcium carbonate overbasing.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Multiple studies with alkyl phenate sulfides (EC 701-251-5; EC 701-249-4; EC 272-388-1) demonstrate low irritation potential and that no hazard classification is warranted.
