Karakteristik Sediaan Body Scrub Residu Garam Rumput Laut Sargassum sp. dengan Penambahan Bubuk Rimpang Kunyit

Abstract

Residu garam rumput laut Sargassum sp. dapat berperan sebagai scrub alami yang diharapkan mampu menggantikan mikroplastik polyethylene. Penambahan bubuk rimpang kunyit berfungsi untuk meningkatkan nilai fungsi sediaan body srub, seperti aktivitas antioksidannya. Penelitian ini bertujuan menentukan penambahan konsentrasi bubuk rimpang kunyit (Curcuma longa) terbaik pada sediaan body scrub residu garam rumput laut Sargassum sp. 7% dengan karakteristik yang sesuai. Sediaan body scrub terbuat dari campuran bahan fase minyak dan bahan fase air dengan penambahan residu garam rumput laut Sargassum sp. 7% dan bubuk rimpang kunyit 0,5%, 1%, dan 1,5%. Produk sediaan body scrub terpilih yaitu SK 7:0,5 (kombinasi residu garam rumput laut Sargassum sp. 7% dan bubuk rimpang kunyit 0,5%) dan telah sesuai dengan acuan yang ditetapkan, kecuali uji daya sebar. Sediaan body scrub SK 7:0,5 memiliki nilai pH 6,52, waktu lekat 1,54 detik, diameter sebar 3,33 cm, emulsi yang stabil, homogen, mampu meningkatkan kelembaban kulit, total fenol 464,52 ± 12,67 mg GAE/g, aktivitas antioksidan CUPRAC 1,20 ± 0,003 μg/mL asam askorbat/g sampel dan ABTS dengan nilai IC50 195,99 ± 1,30 μg/mL.

Sargassum sp. seaweed salt residue acts as a natrual scrub that is expected to replace polyethylene microplastics. The addition of turmeric rhizome powder serves to increase the functional value of body scrub, such as antioxidant activity. The aim of this research was to determine the best concentration of addition turmeric rhizome powder (Curcuma longa) to body scrub Sargassum sp. 7% with the best characteristics. The body scrub was producted from mixing oil and water phase material with the addition of Sargassum sp. seaweed salt residue 7% and turmeric rhizome powder 0.5%, 1%, and 1.5%. The body scrub product selected was SK 7:0.5 (a combination of Sargassum sp. seaweed salt residue 7% and turmeric rhizome powder 0.5%) and was in accordance with the established standards, except for spreadability test. The body scrub SK 7:0.5 had pH value 6.52, adhesion time 1.54 seconds, spread diameter 3.33 cm, stable emulsion, homogeneous, able to increase skin moisture, total phenol 464.52 ± 12.67 mg GAE /g, antioxidant activity of CUPRAC 1.20 ± 0.003 g/mL ascorbic acid/g sample and ABTS with IC50 value of 195.99 ± 1.30 g/mL.
