Spolapon AES 242/70 LD is a highly concentrated anionic surfactant used as the most common ingredient in the formulations of laundry, cleaning and dishwashing detergents, personal care products and cosmetics. It offers rich stable foam, excellent detergency, wetting and emulsifying properties and easy adjustment of the final product's consistency. It is especially valued for its low skin irritation and ready biodegradation, with the undesirable 1,4-dioxane being removed in this variant.
