MAIN STUDY
A. INDUCTION EXPOSURE
Intradermal induction D1
3 injections on the scapular area:
. 0.1mL of Freund's complete adjuvant 50% in 0.9% NaCl
. 0.1mL of TMDAP 0.1% in 0.9% NaCl (treated group) or vehicle (control group)
. 0.1mL of a mixture 50/50 (V/V) of Freund complete adjuvant 50% in 0.9% NaCl and vehicle (for control group) or TMDAP 0.1% in 0.9% NaCl (for treated group)
Cutaneous induction D9
. On day 7, the irritation created with the application of sodium Laurylsulfate 10% in vaseline.
. On day 8, occlusive application on the scapular area of 0.5mL of TMDAP 10% (for treated group) or vehicle (for control group) for 48hours.
B. CHALLENGE EXPOSURE D26
On day 22, 24-hour occlusive application on the scapular area of 0.5mL of TMPDA 1% on the right flank and 0.5mL of the vehicle on the left flank.
Reactions are evaluated 24 and 48 hours after removal of the dressing. - Positive control substance(s):

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- According to the maximization method of Magnusson and Kligman, TMPDA did not induce any sensitization process in the guinea-pig.
- Executive summary:
The delayed contact hypersensivity of tetramethyldiaminopropane (TMPDA) was evaluated in Guinea pigs according a protocol similar to OECD N°406 guideline (Magnusson and Kligman test). The induction phase has been realized both by intradermal route on day 1 (TMPDA 0.1% in vehicle) and by cutaneous route on day 9 (TMPDA 10%) in 2 groups of guinea pigs: 5 males and 5 females for control group and 10 males and 10 females for treated group. The challenge phase was realized on day 24 by cutaneous application of TMPDA 1%; the cutaneous reactions were scored 24 and 48 hours after the challenge phase. Neither mortality nor clinical signs were observed during the study. 24 and 48hours after removal of the dressing, no reaction was observed.
In conclusion, TMPDA did not induce any sensitization process in the guinea pig under these experimental conditions.
