FWIW: Castile soap means that the fat comes from Spanish olive oil. it’s like the champagne monicker. everything other is just olive oil soap.PALMOLIVE is an portmanteau of PALM and OLIVE oils. that's what their soaps were made of, instead of the animal fats (tallow) historically used in UK soap making.COLGATE-PALMOLIVE in the USA is now a 100% detergent manufacturer. not even Murphy's Soap has pine oil in it.it’s different within the subsidiaries.@wiert @gneilyo @TeflonTrout @NilaJones
