Persil power WAS NOT a booster. The WIKI extract is woefully misleading.
Persil Power was a detergent in its own right and replaced micro system in the new products war against P&G.
It was on the market for quite a while, much longer than 6 months. My mum used it quite a fair bit and I cant say we noticed any ruined clothing but then us kids were changing clothes sizes every 2 minutes do i doubt anything had chance to wear out.
Persil Power was the bio version,
Persil Pure a non bio variant
Persil Colour as it suggests.
They came initially in a pouring canister that were designed to be refilled with an eco bag.
