Episode 25 — Dirty Thirty Chemicals: The Surfactant That's Everywhere and Isn't InnocentWelcome to KeysPure.com's Dirty Thirty. I'm Bob Root. Episode Twenty-Five is about Sodium Laureth Sulfate — SLES — probably one of the most recognized names on this list and one of the most commonly used surfactants in personal care products.It lathers. It cleans. It is in your shampoo, your body wash, your face wash, your toothpaste. The foam it creates is the reason most people feel like something is working, even though foam has nothing to do with cleaning efficacy. It's a sensory illusion — and a chemically concerning one.Sodium Laureth Sulfate is an irritant. Animal studies show sense organ effects. Like Propylene Glycol and PEG compounds, it is a penetration enhancer — it alters your skin's structure, increasing the absorption of other chemicals into the bloodstream. In a product that contains multiple questionable ingredients, SLES amplifies the problem.At Keys, we use gentle, plant-derived cleansing agents that clean effectively without stripping your skin barrier or opening a chemical superhighway into your body.
