What Is Laureth-7?
Laureth-7 is a derivative of lauryl alcohol (a non-drying fatty alcohol derived from coconut oil) that functions as a cleansing agent/emulsifier/texture enhancer in skin care formulas. It is also used in other kinds of beauty products, including hair care and makeup.\n\nThe number 7 correlates with the viscosity of this ingredient. The lower the laureth’s numerical value, the lower the viscosity. Not surprisingly, laureth-7 is a liquid. It’s available in natural or synthetic form, with both types being effective.\n\nLaureth-7 has a proven track record of safety in cosmetic use. The 2012 Cosmetic Ingredient Review Expert Panel reaffirmed its safety status (their report looked at products containing 0.001-4%).
