What is Laureth-4?

Laureth-4 is a synthetic compound derived from lauryl alcohol and ethylene oxide. It functions primarily as a surfactant and emulsifier, helping different substances mix together more effectively.

Laureth-4 is commonly used in hair care products like shampoos and conditioners to improve texture and spreadability. Some research suggests that ethylene oxide-derived compounds may pose potential irritation risks for the skin, but the evidence is not conclusive.

When you see Laureth-4 on a label, it's typically used for its ability to create stable mixtures and improve the feel of personal care products.
