Potential of Caulerpa racemosa extracts as sunscreen creams

Caulerpa racemosa contains phenol compounds that have bioactivation as an active ingredient to capture UV radiation. The purpose of this study was to determine the potential of Caulerpa racemosa extract in some solvents. This study used an experimental method consisting of four treatments and five replications, namely Control: Commercial seaweed sunscreen labeled SPF 18, P1: Sunscreen cream with a concentration of 1% extract of Caulerpa racemose n-hexane, P2: Sunscreen cream with a concentration of 1% extract of Caulerpa racemose ethyl acetate, P3: Sunscreen cream with a concentration of 1% extract of Caulerpa racemose ethanol 96%. The best treatment, in sunscreen cream with a concentration of 1% extract of Caulerpa racemose ethyl acetate which has an SPF value of 2.32 ± 0.07 (the effectiveness of protective sunscreen at least 2-4), supported by the results of pH value (Day 0: 7.80 ± 0.11; Day 7: 7.82 ± 0.14). The best treatment hedonic test results, namely in sunscreen cream with a concentration of 1% extract of Caulerpa racemose ethanol 96%, which has an appearance value of 7.13; odor 7.59; texture 6.42; and color 7.09.
