A couple of years ago we tried a variety of UK Persil here in the U.S. Here is what we thought:

UK Persil Bio Powder - Great. Clothes smell wonderful. Cleans better than anything else we ever tried. Very easy rinsing.

UK Persil Colors Powder- Pretty much the same as the Bio Powder.

UK Persil Aloe Vera Liquid - Cleaned well, did NOT like the scent at all Like all the other Persils rinsed out very easily.

UK Persil Silk & Wool Liquid - Much better than Woolite. Nice fragrance too, easy rinsing.

Thank you for a great review, dualref. My daughter is at university in Scotland and was trying to find a good detergent to keep her white shirts nice and bright. I knew Persil would be the best if she was somewhere elese in Europe so I thought she could try the UK variety. It looks like Persil Bio will be it! I will also ask her to bring me some when she comes home for the holidays.

You are welcome!
The Persil Bio powder & liquid (we tried both) is a great detergent and will certainly keep your daughters whites really white! You won't be disappointed.
