Description
D-Galactose (CAS 59-23-4) is a naturally occurring monosaccharide and epimer of glucose, commercially known under names including (+)-Galactose and D-Galactos. It carries no assigned E-code and is classified under HS code 29400090. It occurs naturally in lactose, glycoproteins, and glycolipids.
In personal care formulations, D-Galactose functions as a humectant by attracting and retaining moisture within the skin matrix, and as a skin protectant that supports the integrity of the epidermal barrier. In pharmaceutical and nutritional applications, it serves as a buffering agent to stabilise pH in sensitive biological preparations and as a metabolic substrate in specialised dietary products.
D-Galactose is available in powder form to food-grade and pharmaceutical-grade specifications, with compliance to FCC and Ph.Eur. standards depending on grade. It is subject to REACH registration requirements for supply within the European Economic Area. Procurement teams should confirm grade suitability against their specific regulatory and formulation requirements.
