Mechanism of Action
Lauryl Stearate primarily functions as an emollient, improving skin texture and feel. Its mechanism involves forming a resilient, protective film on the skin's outermost layer. This barrier significantly reduces transepidermal water loss (TEWL), thereby preserving moisture and ensuring the skin remains supple and soft. Within formulations, it also contributes as a lubricant, emulsion stabilizer, and dispersing agent.
