[29, 30] Up to this various workers uses essential oil (Carvacrol and thymol) as core material in microencapsulation process using various shells like alginate,

Microcapsules possessing diverse shell walls like as phenol formaldehyde,
[36]
urea formaldehyde, [37] melamine formaldehyde, [38, 39] polyurethane,
[40]
and polyurea [41] have been formulated. It is found that Carvacrol and thymol are reported as core material in microencapsulation, [15, 30-35] but no one reported these as shell materials in microencapsulation technique. Establishment of novel shell is inimitable idea of this work. Carvacrol and thymol are the biobased phenols,
[28-30]
phenol– formaldehyde (PF) microcapsules with various cores were produced by applying in situ polymerization technique.
[42, 43] The prettiness of present research work is that invented new shell materials carvacrol-formaldehyde (CF), thymol-formaldehyde
(TF), and carvacrol-thymol-formaldehyde (CTF) for encapsulation of
