General description
Carnauba wax No.1 yellow(CW) is an ester based wax that can be extracted from palm leaves. The composition of this wax contains aliphatic esters, ω-hydroxy esters and unsaturated alcohols. It can be used as a glossing agent in a variety of pharmaceutical products.[1]
Application
CW may be used as a hydrophobic excipient which can be used to modify the kinetics of polymeric gel in a drug releasing system.[2] It can be used in dry polymeric coatings which can increase the crystallization and improve the stability of amorphous solid drug formulations.[3] It may also be used as a component of lipids which can be used to tune and improve the flowability and designing of solid drugs.[4]
