Sodium Stearoyl Lactylate (CAS 25383-99-7) is an anionic food-grade emulsifier derived from stearic acid and lactic acid, a white powder that strengthens dough and complexes with starch in industrial baking and serves as a conditioning emulsifier in personal care lotions and creams. It is widely valued for its high stability and superior dough-strengthening properties in industrial baking and processed food applications.
Functioning as a potent surfactant, SSL interacts with gluten proteins to improve volume, texture, and crumb softness in yeast-raised products. Its ability to complex with starch allows for significant shelf-life extension by retarding the staling process in commercial bakery goods.
Beyond nutrition, this high-purity powder serves as a conditioning agent and emulsifier in personal care formulations like lotions and creams. It provides excellent oil-in-water stability, ensuring a smooth skin feel and consistent viscosity in cosmetic products.
