Description of key information
The dermal irritation of Phenol, ethoxylated, esters with acrylic acid was investigated in one study, showing mild to slight irritation. Well-defined dermal irritation was observed in two of three animals 4 hours after application, and with the primary irritation index (PII) of 1.2. The CLP-criteria for a classification as skin irritant is therefore not met.
No data was available on eye irritation is available for Phenol, ethoxylated, esters with acrylic acid, therefore read-across has been made to 2-phenoxyethyl acrylate. The eye irritation of 2-phenoxyethyl acrylate was investigated in a rabbit study, showing slight irritation after 48 hours. However, the irritation had disappeared at 72 hours hence it is fully reversible. The criteria for CLP classification as eye irritant is therefore not met. Due to structural and pysico-chemical similarity to Phenol, ethoxylated, esters with acrylic acid, this can also be concluded for Phenol, ethoxylated, esters with acrylic acid as well.

- Basis:
- mean
- Time point:
- 24/48/72 h
- Score:
- ca. 1.2

- fully reversible within: 96 hours
- Irritant / corrosive response data:
- Well-defiend erythema with very slight-to-slight oedema was observed in two animals from approximately one hour after bandage removal following the four hours exposure. Reaction had resolved in both animals by Day 4 (96h). No dermal irritation was observed in the remaining animals throughout the study.

- Migrated information Criteria used for interpretation of results: US CPSC / US FDA
- Conclusions:
- The skin irritation potential of M142 was tested using semi-occlusive application for four hours in three Rabbits (one male and two females) according to OECD test guideline 404. Dermal irritation was observed in two of three animals 4 hours after application. The primary irritation index (PII) was calculated to be 1.2. Based on the present test M142 was not subject for classification as a skin irritating substance.
- Executive summary:
The skin irritation potential of M142 was tested using semi-occlusive application for four hours in three Rabbits (one male and two females) according to OECD test guideline 404.
Dermal observations were made three minutes, one hour, four hours, 24, 48 and 72 hours after removal of the semi-occlusive dressing. Well-defined dermal irritation was observed in two of three animals 4 hours after application. The primary irritation index (PII) was calculated to be 1.2. Mean values of erythema and oedema were below the values triggering CLP classification. Hence, based on the present test M142 was not subject for classification as a skin irritating substance.

Additional information
The available experimental data suggest that Phenol, ethoxylated, esters with acrylic acid (M142) is not corrosive, as all observed effects were fully reversible.
The key study on dermal irritation found that two of three animal had dermal reactions, leading to a primary irritation index of 1.2. The major criteria for classification as irritant is therefore not met ( at least two of three animals, with a mean score between 2.3 to 4.0).
The data from a study with the read-across substance 2-phenoxyethyl acrylate (S1) showed that all animals have ligth redness, score 1, which was only persisting in one animal after 48 hours (ligthly increased redness) and fully reversible in all animals after 72 hours.

Justification for selection of skin
irritation / corrosion endpoint:
OECD TG 404 study in rabbits, performed according to GLP.
Justification for selection of eye irritation endpoint:
No studies were available for Phenol,
ethoxylated, esters with acrylic acid. Hence, read-across was made to an
in vivo eye irritation study for 2
-phenoxyethyl acrylate.
Effects on skin
irritation/corrosion: slightly irritating
Effects on eye irritation: slightly irritating
Justification for classification or non-classification
A skin irritation study (4 hours exposure) found that Phenol, ethoxylated, esters with acrylic acid was slightly irritating but reversible., dermal reactions were observed only in two out of three animals, and with the dermal irritation index of 1.2. The major criteria for a classification as skin irritant is therefor not met.
For classification as an eye irritant the criteria was also not met, as the reactions observed were fully reversible, and mean scores following grading 24, 48, and 72 hours were lower than the criteria set in table 3.3.2 in Regulation (ec) 1272/2008.
