- Irritant / corrosive response data:
- Application of the test item to healthy intact rabbit skin resulted in a primary irritation index of 1.33. Local signs (mean values from 24 to 72 hours) consisted of grade 1.22 erythema and grade 0.11 oedema. Very slight to well defined erythema was observed in all animals 1 hour after treatment and persisted in two animals up to the 48 hour reading and in the other animal up to the 72 hour reading. Very slight swelling at the test site was noted in one female 1 hour after the treatment and in the other female 24 hours after treatment. Slight scaling of the skin at the test site was evident in the male at the 72 hour reading. In addition, the skin of this animal was noted to be dry and inelastic from 24 to 72 hours after treatment. Slight to moderate scaling at the test site was also noted in both the females from 7 to 10 days or from 72 hours to 10 days after treatment. The skin of these two female animals was similarly noted to be dry and inelastic from 48 to 72 hours or from 24 to 72 hours after treatment. All skin reactions had cleared within 14 days of treatment. No staining by the test item of the treated skin was observed. No irreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin.
- Other effects:
- No clinical signs or systemic toxicity were observed in the animals during the study and no mortality occurred.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In the in vivo skin irritation study with N-ethyl-3-trimethoxysilyl-2-methyl-propanamine, conducted according to OECD Test Guideline 404 and in compliance with GLP, the test substance was concluded to be not irritating to rabbit skin.
