Preparation and Application of VE Microcapsules with Polyurethane Shell for Skin-Care Textiles

Abstract:

Vitamin E (VE) microcapsules with polyurethane (PU) shell are successfully prepared via interfacial polymerization of polyurethane with toluene-2,4-diisocyanate (TDI) as the isocyanate, polyethylene glycol as the polyol, and 1,4-butanediol (BD) as the chain extender. In the preparation process, VE emulsion, prepolymer and microencapsulation of VE are studied using a particle size analyzer, butylamine titration, optical microscopy (OM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Based on the present research, VE microcapsules prepared have smooth surfaces and spherical appearances, the mean particle size of about 550 nm. Vitamin E microcapsules have been glued effectively to textiles, and a kind of skin-care product has been developed.
