If you have any of this... ...here's what you can do with it. You can either throw it away or you can use it to turbocharge your Colgate or Williams. Just squeeze a small dollop (pea size) onto the puck and proceed to lather as usual. You may need to experiment with the amount. Too little will have no effect on the lather and too much will effectively kill it. But get it just right and you will see your hard-to-lather pucks transformed into little factories of rich long-lasting goodness. Try it!
I don't have Palmolive cream, but I do like the stick form. Cremo cream does give that "a little something extra" to under performing soaps. While I'm not a Purest insisting no one alter or molest their soaps - I have gotten a usable lather from vintage Colgate. I leave modern Williams for those that like it. Vintage Williams is a whole 'nother matter - great all by it's self!
It deserves it's own discussion. I'd like to pin a date on the box mine came in. Printed label says 15¢. Classic drug store product.
I would love to figure out dates. I have seen adds gor the barbershop soap from 1917. I do not know when they started or stopped the mug soap.
