Results and discussion

Results of examinations:
irritation: 31/49 individuals
sensitizing: 24/49 individuals

Any other information on results incl. tables

Irritation:

The test material elicited irritation in 31/49 individuals.This was well over 50 % of the panelists participating in the study. Minimal or moderate erythema was the extent of irritation in seven (7/49) of these individuals, the picture in the remaining 24 individuals was quite different.

Sensitizing:

During induction phase: 24 individuals (24/49) showed intensive or very intense irritation, consisting of erythema, induration, weeping, and extension beyond the margin of the contact site. The characteristics of these responses were consistent with that of a sensitizing effect.

Applicant's summary and conclusion

Executive summary:

The test substance (75 % preparation in pet.) induced a allergic response in 24/49 human volunteeres (Monsanto Co.1982).
