Having just checked, I've noticed that even the TSA in metric hating USA give their limits at "3.4oz (100ml)" - so clearly 100ml is the limit, and 4oz is over the limit.
Accordingly, I would not have attempted 4oz, unless 4oz (rather than 100ml - 3.4oz) was a vital quantity to have with you.
For 2 of the 3 solutions I require, 4 ounces is the smallest size made. I actually had no choice.
