Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

other: Study following in-vitro guideline under validation
Principles of method if other than guideline:
Ocular Irritection Assay System (refinement of the former Eyetex method)The system evalutes the ocular hazard effects of test chemicals based on the premise that eye irritation and corneal opacity after exposure to rirritating substances is the result of perturbation or denaturation of corneal proteins. The test method maels use of a macromolecular reagent composed of a mixture of proteins and glycoproteins, carbohydrates, lipids and low molecular weight components, which when rehydrated, form an ordered molecular matrix mimicking the structure of the transparent cornea. Irritatn substances produce a turbidity of the reagent by changing both protein conformation and degree of hydration. Changes in the turbidity of the reagent solution caused by the tested material can be quantified by measuring an increase in the light scattering detected at a wavelenght of 405 nm with the help of a spectrometer. The increase in optical density produced by the test material is compared with that prodcued by a set of calibration substances eahc of which having rpeviously estimated in vivo irritancy potential.

Interpretation of results:
Migrated informationunder Regulation 1272/2008
The substance was tested for eye irritation potential by means of Ocular Irritection Assay. Under the experimental conditions the substance showed eye irritation properties.
Executive summary:

The substance was tested for eye irritation potential by means of Ocular Irritection Assay. Doses of 1, 5, 10 and 25 % of the test item were applied to the matrix mimicking the ordered structure of the cornea for 5h. Irritection score were all in the mild range. Under the experimental conditions the substance showed an increase in turbidity and therefore eye irritation properties classified as H319 Category 2.

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (irreversible damage)

Additional information

In vitro Irritection tests are available for both eye and skin irritation properties (Ricci; 2002) on the substance and on a group of substances that differ from the target substance only for the lenght of the fatty acid in the final structure.

Eye irritation was determined by Ocular Irritection Assay on the substance (and similar substances) with a result as a mild/modearte eye irritant in the Draize score system.

Skin irritation was determined on a similar substance by Dermal Irritection Assay, which resulted as mild skin irritant. However, based on the considerations reported in the attached document and on the read across considerations no skin irritation potential is considered for the substance while eye irritation potential is classified as H318.

Effect level: empty Endpoint conclusion: Adverse effect observed

Justification for classification or non-classification

The irritative scores determined by the Irritection Assay (dermal and Ocular) classify the substance as H318 and do not classify the substance for skin irritation under Regulation 1272/2008 ( refer to the attached document).
