Beeswax Nanoemulsion for Consolidation and Hydrophobization of Canvases
ChemPlusChem, EarlyView.A beeswax‐CNC/EHM composite system is developed for the consolidation and hydrophobization of canvases. The beeswax nanoemulsion is prepared using a spontaneous emulsification method based on the Ouzo effect. The interactions between CNC, EHM and beeswax resulted in a stable and uniform layer upon drying, synergistically providing both reinforcement ...
