BTW suds have nothing to do with cleaning power. The companies add more or less of the stuff to suit the sales gimmick of the day
A bit off the trivia topic but agreed. Suds mean nothing and you need MUCH less detergent than what they say. It's all a gimmick to get you to buy more.
I have sensitive skin and most laundry detergents were bothering my skin. I switched to Palmolive dish soap and a bit of vinegar in my homemade laundry soap years ago and no problems since.

Vinegar is also a natural fabric softener.
