A surfactant derived from coconut and palm oil, it is a very mild cleansing agent with a dense and luxurious foam and an elegant after feel. It also has excellent water solubility and thus good rinsability. Surfactants are found in most cleansing products as they degrease, emulsify oils and fats, and suspend oil in order for it to be washed away. And while some surfactants can be drying and irritating, Sodium Lauroyl Methyl Isethionate has proven to be mild and gentle. This is because it is a large molecule ingredient, which means it cannot penetrate the skin; and therefore, not irritate it either.
