- Irritant / corrosive response data:
- Score per animal is not available in the publication: mean values are presented. No edema score is presented.
The clinical inflamatory response varied from minimal erythema to marked erythema with slight vesiculation. The frequency of positive response (irritation index of 1 minimum) is 57 in vulvar test site and 9% in forearm test site.
Besides, a significant difference in skin reactivity is observed between forearm and vulvar sites.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (corrosive) based on GHS criteria
- Conclusions:
- At a concentration of 17%, the clinical inflamatory response varied from minimal erythema to marked erythema with slight vesiculation. The frequency of positive response (irritation index of 1 minimum) is 57% in vulvar test site and 9% in forearm test site.
Besides, a significant difference in skin reactivity is observed between forearm and vulvar sites. - Executive summary:
In a clinical open test at 17% benzalkonium chloride in 21 human volunteers, the clinical inflamatory response varied from minimal erythema to marked erythema with slight vesiculation, and a significant difference in skin reactivity is observed between forearm and vulvar application sites.
The frequency of positive response (irritation index of 1 minimum) is 57% in vulvar test site and 9% in forearm test site.
