Washing powder/liquid - if the label is green it's bio, if it's blue it's non-bio. This is true across every brand I've found.
When cooking with chilli peppers - 'wash' your hands with a bit of oil afterwards to remove all the burning chilli chemicals. Then wash with soap.
The number of times I've rubbed my eyes after handling chillies is ridiculous, I could have saved myself so much discomfort!
