SLES 70

SLES is a modified, improved version of SLS. It takes the high ground with a series of benefits such as long-lasting bubbles, still commonly perceived as a sign of high cleaning power. It has been proven to cause minuscule levels of skin irritation, without stripping the epidermis of excess moisture – a perk highly desirable among customers. Moreover, SLES shows almost no sensitivity to hard water, which allows for the formulation of products suitable for a worldwide market.
On top of all, sodium laureth sulfate’s biodegradation capacity meets the eco-protection requirements. SLES biodegrades rapidly and in entirety.SLES is contained in many personal care products such as soaps, shampoos, body washes/bubble baths, toothpaste, washing liquids, shaving cream, mouth wash, and even sunscreens.
Sodium laureth sulfate is used in a range of concentrations. In cosmetics, it can go from as little as 0.01% up to 50% of the formula. In cleaning products, the common range is from 1% to 30%.
