Abstract
Tubuh akan tetap memproduksi radikal bebas dari metabolisme
sel normal, peradangan, malnutrisi maupun respons terhadap efek
eksternal yang dihasilkan. Salah satu zat yang bisa memicu
penghambatan terhadap pembentukan radikal bebas mengakibatkan
penuaan pada kulit yaitu antioksidan. Teh memiliki kandungan
senyawa fenolik yang berfungsi sebagai antioksidan. Studi ini bertujuan
untuk mengetahui formulasi dan aktivitas antioksidan sabun cair wajah
ekstrak etanol daun teh hijau (Camellia sinensis L.).
Formulasi sabun cair wajah ekstrak etanol daun teh hijau dalam
studi ini digunakan variasi konsentrasi surfaktan sodium cocoyl
isethionate 4%, 8% dan 12%. Ekstrak tanaman diperoleh dengan
metode maserasi dengan pelarut etanol 70%. Pengujian sediaan sabun
wajah terhadap mutu fisiknya mempergunakan uji organolepis, pH,
homogenitas, tinggi busa, alkali bebas, bobot jenis dan viskositas, serta
dilakukan cycling test. Pengujian aktivitas antioksidan sediaan sabun
cair wajah secara in vitro mengggunakan metode DPPH (1,1-diphenyl
2-picrylhydrazil).
Hasil studi diperoleh bahwa semua formula sediaan sabun cair
wajah ekstrak etanol daun teh hijau (Camellia sinensis L.) bermutu
fisik dan berstabilitas baik sesuai SNI, formula terbaik ditunjukkan oleh
formula 5 dan aktivitas antioksidan paling baik ditunjukkan oleh
formula 4 dengan nilai IC50 10,5685 ± 0,2211 ppm.
The body will continue to produce free radicals from normal cell
metabolism, inflammation, malnutrition and in response to external
effects. One of the substances that can trigger inhibition of the
formation of free radicals resulting in aging of the skin is antioxidants.
Tea contains phenolic compounds that function as antioxidants. This
study aims to determine the formulation and antioxidant activity of
facial liquid soap ethanol extract of geen tea leaves (Camellia sinensis
L.).
The formulation of geen tea leaf ethanol extract facial liquid soap
in this study used various surfactant concentrations of sodium cocoyl
isethionate 4%, 8% and 12%. Plant extracts were obtained by
maceration method with 70% ethanol solvent. Testing of facial soap
preparations for their physical quality uses organoleptic tests, pH,
homogeneity, foam height, free alkali, specific gavity and viscosity, as
well as a cycling test. Testing the antioxidant activity of facial liquid
soap preparations in vitro using the DPPH (1,1-diphenyl-2
picrylhydrazil) method.
The results of the study showed that all formulas for facial liquid
soap ethanol extract of geen tea leaves (Camellia sinensis L.) had good
physical quality and stability according to SNI, the best formula was
shown by formula 4 and the best antioxidant activity was shown by
formula 4 with an IC50 value of 10.5685 ± 0.2211 ppm.
