At Humboldt Soap Company the fragrances we use are phthalate free and we use mica colorants. Our skin nourishing soaps are handcrafted in small batches using the cold process method. We also 'super-fat' our soaps during the making process which means the soaps retain more oils and butters for a more luxurious bar. Our soaps are then cured for 4-6 weeks to make sure they are perfect for you. Each REAL soap bar is made with skin nourishing natural oils and butters without fillers or detergents (don't get me started) like you find in manufactured bars that pass for soap.
