Application

  • Synthesis of lactose-based surfactants: Research by Enayati, Gong, and Abbaspourrad demonstrated the use of d-Lactose monohydrate in the synthesis of lactose lauryl ester, employing aluminosilicate zeolite as a catalyst. This study presents a method for producing non-ionic surfactants, highlighting d-Lactose monohydrate′s role in industrial and pharmaceutical applications (Enayati et al., 2019).
