Dr. Bronner's Tea Tree Pure Castile Soap is their phenomenal new soap for the millennium. The therapeutic benefits of Tea Tree oil can now be reaped in an unsurpassed pure castile base. Use for facial cleansing and cleaning minor cuts and scrapes, as well as everyday bathing. 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.
