What is Sodium Lauryl Ether Sulfate 70% and Its Uses?

Sodium Lauryl Ether Sulfate 70% (or SLES 70%) is pretty common across a bunch of industries these days. Basically, it works really well as a surfactant—that’s just a fancy way of saying it helps stuff get clean. You’ll mostly see it popping up in personal care products like shampoos and body washes, as well as cleaning supplies. I read in a report by Grand View Research that the global market for surfactants hit over $40 billion in 2021 alone. And honestly, that number keeps climbing because more people want products that are both effective at cleaning and gentle on the skin. One thing that makes SLES 70% stand out is how much it bubbles up—foaming is its thing, which is why it’s a big hit in shampoos and body washes. Plus, it does a decent job at pulling dirt and grime off surfaces when you’re cleaning. But, of course, there are some concerns floating around—like how biodegradable it is and whether it might irritate your skin. With all the buzz about being eco-friendly these days, a study in the Journal of Surfactants and Detergents points out that we really need greener alternatives. Even though it’s pretty widely used, it’s worth thinking about the whole formulation process. Not all suppliers deliver the same level of purity with their SLES 70%. That variation can even affect how well it works and whether it’s safe to use. The way it’s made and where the ingredients come from really matter—these choices can ripple through the entire supply chain. So, if you’re involved in product formulation, understanding these little details can make a big difference in making smart, informed decisions.
