    Calfoam® ES-302 is an anionic surfactant that provides luxurious, mild, and copious foam that is gentle to the skin and is perfect for personal care and HI&I formulations. Calfoam® ES-302 is a great flash foamer, creates very dense foam and performs well under a range of conditions in formulations when used alone or in combination with other surfactants. Calfoam® ES-302 has a high tolerance for pH increases and is relatively unaffected by changing water hardness, which enables many industrial cleaner formulations to benefit from using this surfactant. Calfoam® ES-302 is perfect for bubble bath, shampoo, shower gel, facial cleanser, liquid hand cleaner, fabric care, hand dish wash, and car care products.

    Storage & Handling

    Storage and Handling Information

    Store in a plastic or plastic lined steel, tightly closed container. Do not store with oxidizing agents. 1,4-Dioxane levels may change as a result of time, temperature, pH and other product ingredients. Do not store product above ambient temperature (~65-78°F or ~18-26°C). Storage of product above ambient temperature can generate, affect or increase 1,4-Dioxane levels in the product. Avoid contact with eyes, skin and clothing. Wear appropriate personal protective equipment and observe good industrial hygiene practices. Material is slippery on wet and hard surfaces.
