Oleth-3 Phosphate
What is Oleth-3 Phosphate?
Oleth-3 Phosphate is a phosphate ester derived from oleyl alcohol, which undergoes ethoxylation to form Oleth-3 before phosphorylation. This creates an anionic surfactant commonly used in rinse-off products like shampoos, body washes, and facial cleansers, as well as leave-on items such as lotions and creams. It works by reducing surface tension between liquids and solids, facilitating the removal of dirt, excess oils, and makeup without stripping the skin's natural barrier. As an emulsifying agent, it forms a protective film at the oil-water interface, preventing separation and ensuring a smooth, uniform texture in multi-phase formulations. Its structure balances cleansing power with relative gentleness, making it suitable for everyday personal care products.
