However, this MSDS is for liquid Tide, which didn't exist in the

I wonder what the formula was back then? It will have had something
like 10% phosphorus in it.

Since the 1940's the most effective ingredient has been the
alkylbenzenesulfonate surfactant.

How it works:

Thanks; I'll look into this.

But for instance the user's manual for my circa 1999 dishwasher says if
the detergent is less than 8% phosphorus, they (Bosch) do not guarantee
dishwashing performance.
