Used primarily as a wetting agent and anionic surfactant in industrial, household, and textile applications. It enhances the spreading and penetration of liquids on surfaces, making it effective in hard surface cleaners, metal degreasers, fiber cleaning, dyeing processes for even color penetration, and emulsion polymerization. Its strong water softening properties improve performance in hard water conditions. Also found in agricultural sprays to help pesticides and fertilizers adhere to plant surfaces. Provides good foam stabilization and is valued in products requiring rapid surface tension reduction. Low skin irritation makes it suitable for personal care formulations like liquid soaps and detergents.
