Abstract

Recently, the utilization of the herbal skincare industry has drawn much attention. One component utilized in formulations to provide a gel-like consistency and maintain the stability of a medical preparation is carbopol-940, a cosmetic gelling agent. It is frequently combined with an emulgator, triethanolamine. This study aims to assess the effect of blending Carbopol-940 and triethanolamine in the formulation of a cocoa peel extract gel using the Simplex Lattice Design (SLD) approach. In principle, using a magnetic stirrer, the water and oil phases are mixed to produce the gel at 700C. The procedure begins with dissolving Carbopol-940 in water, which is then combined with triethanolamine to form the base. After combining the gel base and emulsion, cocoa fruit peel extract is added. The SLD method was employed to evaluate the physical characteristics of emulgel (adhesion, viscosity, and dispersibility) to determine how Carbopol-940 and triethanolamine affected those characteristics. The result showed that using carbopol 940 and triethanolamine simultaneously significantly affected the adhesion and viscosity of cocoa peel extract emulgel. The ratio carbopol-940 to triethanolamine 1:8 gave the best physical properties- it shows a spreading power of 5.50-5.60 cm, an adhesive power of 1.16-1.25 seconds, and a viscosity of 20,456-21,472 mPa.s. Furthermore, compared to triethanolamine, carbopol 940 has a more substantial impact on the emulgel of cocoa peel extract. In conclusion, carbopol 940 and triethanolamine simultaneously had a major effect on the adhesion and viscosity of cocoa peel extract emulgel. Meanwhile, carbopol 940 has a greater effect on the emulgel of cocoa peel extract than triethanolamine.
