Abstract

ABSTRACT Coconut oil is one of the soap base materials that can be used, because it has a high content of lauric acid. The addition of white tea extract served as an active substance to add properties functions. The purpose of this study was to determine the effect of adding white tea extract to the characteristics of liquid soap. This study was used an experimental laboratory method with regression-correlation analysis and descriptive analysis. The treatments in this study were the addition of white tea extract concentrations (1% v / v) of A = 0% (w / v), B = 0.5% (w / v), C = 1.0% (w / v), D = 1.5% (w / v), and E = 2.0% (w / v), out of 300 grams soap basis. Parameters observed included specific gravity, pH , total plate count, organoleptic test, and antibacterial test of liquid soap. The analysis results showed that every formulas met the requirement based on SNI 06-4085- 1996 of liquid soap. The liquid soap formula with D treatment was the best product according to organoleptics test with a percent of 40 %. The antibacterial test was showed liquid soap formula with E treatment has a strong bacterial inhibitory activity of 12.93 mm ± 0.33 with a specific gravity value of 1.025 g/g± 0.002, pH 9.23± 0.059, and a total plate value of 5.5 x 104 colonies / g ± 0 .
