I don't know whether the "ranch mayonnaise" you had was a commercial product or simply something the supermarket whipped up to put on sandwiches.

In any case, both the dressing and mayonnaise are likely ...


Ranch mayonnaise has mayonnaise as the only base ingredient, whereas ranch dressing has mayonnaise and another ingredient, in this case buttermilk.
