There is an patent available for encapsulation technique using fumed silica. I tried it but facing problem for the gelling step I used 0.5 gm SiO2 dispersed in 60 gm of water then adding fragrance oil. It does work but the next haven’t been able to crack which involves further coating the silica with calcium chloride can anyone guide regarding this.
