Dr. Bronner’s Peppermint Pure Castile Soap is their most popular variety. The peppermint essential oil creates an exhilarating chilly-tingly-cool body space. Because peppermint oil is a mild stimulant, it increases vitality and clarity. The original all-natural soap. Quality soap-making consists in great part in choosing the right proportions of the right oils with their different fatty acids. Most commercial soaps skimp on quality because of cost, and use lots of tallow from beef fat with a little bit of coconut or palm kernel oil. Dr. Bronner’s (All One) unsurpassed soaps use olive, hemp, and palm oils instead of tallow, and use three to four times more coconut oil than commercial soaps. Saponified coconut oil generates high-lather cleansing even in hard water because it has shorter-chain saturated fatty acids. Hemp, olive, and palm based soaps make a mild, smooth, creamy lather, because these oils contain longer chain unsaturated and polyunsaturated fatty acids.
