Is it just me that doesn't understand the american washing powders avaialble in Publix?

Whats the difference between our washing powder and the american stuff? why does it have bleach added to it?

I don't use bleach on my clothes at home, would it damage my clothes if I used the american stuff?

I normally take some Persil out with me but would rather not have to?

any clues??[msnembarrased][msnembarrased]
