3 additional animals were exposed for 3 minutes each. The mean erythema
score was 0.6 and the mean edema score was 0. Effect was reversible
within 72 hours.
Washing immediately after exposure significantly reduced the severity
and duration of the effect.
See attached table for details.
The skin irritation potential of Toluene 4-sulphonic acid was assessed following official guideline OECD 402, Acute Skin Irritation/Corrosion. The skin of the animals showed a clearly circumscribed to severe erythema and a noticeable oedema. In addition, the skin surface was partly dry and brittle and flaky or brown over a large area. Hardening and scab formation were also observed. The effects were seen after 7 days post administration.
