The Effect of the Percentage of Robusta Coffee Ground (Coffea canephora) and Heating Temperature on the Characteristics of Body Scrub

Abstract

Body scrub is one of the cosmetic products used for skin care. Body scrubs have coarse granules that function  to remove dead skin cells and clean the skin optimally, which is called abrasive or sanding. This study aims to  determine the effect of the percentage og coffee grounds and heating temperature and their interaction on the  characteristics of the body scrub and to determine the percentage of coffee grounds and the right heating  temperature so as to produce a body scrub with the best characteristics. This study used a factorial randomized  block design with two factors. The first factor is the percentage of coffee grounds with 3 levels, namely 4, 6  and 8%, while the second factor is the heating temperature with 3 levels, namely 65, 70 and 75˚C. The results  showed that the percentage of coffee grounds had an effect on ph, viscosity, spreadability, adhesion, total  phenolic compounds and overall body scrub acceptance. The heating temperature affects the viscosity,  spreadability, adhesion, total phenolic compounds and overall acceptance of the body scrub but the heating  temperature has no effect on the ph of the body scrub. The interaction between the percentage of coffee grounds  and the heating temperature had no effect on ph, viscosity, spreadability, adhesion, total phenolic compounds  and overall acceptance of the body scrub. The percentage of 4% coffee grounds and a heating temperature of  65˚C is the best treatment of body scrub with characteristics of ph 5.93, viscosity of 7600 cp, dispersion of 5.6  cm, adhesion of 5.78 seconds, separation ratio = 1, total phenolic compounds 1.52 mg GAE/g and overall  acceptance was 4.95 (regular to moderate).
