Yes, Persil Has Zeolites
As well as most other powdered laundry detergents the world over. Zeolites were introduced ages ago as away to soften wash water using less and or no phosphates.
Zeolites are an insoluble clay substance that IMHO can build up in fabrics and or also contribute to the "lint" one sees coming off textiles when laundered in products containing the stuff.
When one washes with vintage and or liquid detergents you notice the wash water isn't "cloudy" but various stages of milkly clear (depending upon the chemistry of the cleanser in question), but detergents with Zeolites will always have murky wash water.
Happily the commercial European detergent powder in one's stash is free of Zeolites and have a decent stash of both vintage cleansers as well as liquid. In a pinch can also use Calgon water softener and soap! *LOL*
Persil mega-perls are the only "powder" detergent in one's stash that am sure has Zeolites. Vintage boxes of Tide, All, Cold Power, Rinso, Gain,and a few others were made during the hey day of phosphates so think am safe there.
I never use Zeolite containing detergents on my bed or table linen; but that's just me.
