PEG-20 Glyceryl Triisostearate has a high molecular weight, which prevents it from penetrating past the skin's surface. It is available for DIYers, but it can be difficult to find. Some possible suppliers include Croda, Glamour Cosmetics, and The Formulary. Cithrol 10GTIS is a highly effective and mild surfactant. It can also be used to create simple oil cleansers, emulsifying cleansing oils on contact with water so they can be rinsed from skin on application of water. The microemulsion and oil cleansers are very effective at removing long wear and waterproof make-up while leaving the skin feeling renewed, smooth and soft to touch.
