These soaps are handmade using a traditional method of cold process.  Oils and butters are mixed with sodium hydroxide (lye), wrapped up and put to bed for 24 hours in the mould.  They are then taken out of the mould, hand cut and then left for 2-4 weeks to cure. 

Please be assured that once chemically reacted with the oil/s in correct proportions, absolutely no caustic properties remain in the soaps. All soaps start out this way, hence the scientific words for the different soaps all beginning with 'Sodium', i.e. sodium palmate (soap made with palm oil).
