Effect of cacaoate in lipstick formulation

Abstract

Cetyl cacaoate is a cosmetic wax derivedfrom cocoa butter deodorizer distil/ate with the melting point of 55C. A mixture design of Simplex centroid for Cetyl cacaoate ", jojoba ester and carnauba wax was carried out to study the effect of Cetyl cacaoate towards lipstick strength and its spread ability. Lipstick strength l'laS determined through parameters of stick hardness, stick resilience and stiffness, which were measured by TA.XT.Plus texture analyser fitted with cantilever rig (AILC) at (28 llC. The spread ability of the lipstick was by sensory evaluation by trained panelists. Generally, Cetyl cacaoat/M in the blending reduced the hardness of the lipstick but it enhanced the stick resilience and stiffness of the lipstick. Sensory evaluation showed that existence of Cetyl eacooate'" in the blending was able to enhance the attribute of spread ability during application on lips
