Sažetak
Microencapsulated fragrant oil with melamine- formaldehyde shell was synthesized through interfacial polymerization. The effects of molar ratio melamine (M) - formaldehyde (F) monomers and types of surfactants: Tween 20, Tween 80, SLS and CTAB. The investigation was carried out using thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The results have shown that the microcapsules obtained using the emulsifier Tween 80 and the molar ratio 1:6 of M-F monomers showed particle size smaller than the microcapsules using the emulsifier SLS, CTAB and Tween 20 and the molar ratio 1:4 and 1:3 of M-F monomers.
