Disodium laureth sulfosuccinate or DLS is a cleansing ingredient that is used to help improve the cleansing abilities of skincare products. It is generally considered to be less harsh than other cleansing ingredients such as sulfates. DLS is a common ingredient in shampoos, cleansers, and body washes. This is mainly due to its ability to lift oils and dirt from the skin, allowing them to be easily rinsed away. DLS also helps to improve the foaming of the product and helps to stabilize the product. DLS is not considered a sulfate, while the name may seem similar to sulfates such as sodium lauryl sulfate, it is considered to be far gentler on the skin and non-irritating.
