Sodium C8-16 Isoalkylsuccinyl Lactoglobulin Sulfonate

What is Sodium C8-16 Isoalkylsuccinyl Lactoglobulin Sulfonate?

Sodium C8-16 Isoalkylsuccinyl Lactoglobulin Sulfonate is a cosmetically modified derivative of lactoglobulin, a natural protein sourced from whey in milk. Through chemical processes, it incorporates C8-16 isoalkyl succinyl groups and sulfonation, resulting in an amphiphilic molecule with improved water solubility and surface-active properties. Commonly featured in shampoos, conditioners, and cleansing formulations, it functions dually as a surfactant—reducing surface tension for effective yet gentle removal of dirt and oils while generating foam—and as a conditioning agent. By adsorbing onto hair shafts and skin surfaces, it creates a lubricious layer that minimizes friction, enhances slip, and promotes a smoother, more manageable feel. This makes it suitable for daily rinse-off products where mildness and performance are key, offering a protein-based option distinct from traditional synthetic alternatives.
