Sodium lauryl sulfate (SLS) and Sodium laureth sulfate (SLES) are nasty foaming agents that can be found in up 90% of common personal care and cleaning products. A major concern about SLS and SLES is its potential to interact and combine with other chemicals to form nitrosamines, a carcinogen. All our cleansers use natural cleansing agents that will deeply cleanse, detox and leave the skin feeling fresh.
