Detailed Analysis
Lactitol (4-O-β-D-galactopyranosyl-D-glucitol, CAS 585-86-4) is a sugar alcohol produced by hydrogenation of lactose. It is widely used as a food sweetener (E966) and pharmaceutical excipient. In cosmetics, it functions as a humectant and skin-conditioning agent, binding water to maintain hydration.
