In the present article, the author considers factors for sulfate vs. sulfate-free formulating, including cost, foam and viscosity. In addition, two test formulations with and without sulfates are compared. The author concludes that little sound science exists to support the current “sulfate-free” market trend, especially when considering the potential benefits sulfates can impart in formulations.
