The number 3 correlates with the viscosity (thickness) of this ingredient. The higher the laureth’s numerical value, the greater the viscosity. Laureth-3 is a polyethylene glycol ether of Lauryl Alcohol (q.v.). Laureth-3 has a proven track record of safety in cosmetics. In 2012, the Cosmetic Ingredient Review Expert Panel reaffirmed its safety status. Their report looked at products using concentrations between 0.0004-20%, although typical use levels are closer to 1-5%. Laureth ingredients are polyethylene glycol ethers of lauryl alcohol that contain repeating ethylene oxide units. These ingredients are useful in cosmetic and personal care products as surfactants, cleansing agents, emulsifiers and solubilizers. Laureth-3 is also used as a texture enhancer/thickening agent and its solubilising properties make it popular in products where a milky consistency is desired.
