Pengaruh Konsentrasi PVA terhadap Stabilitas dan Aktivitas Antioksidan Masker Peel Off Ekstrak Kulit Jengkol (Archidendron pauciflorum (Benth.) Nielsen)

Abstract

Abstract
 Jengkol skin (Archidendron pauciflorum (Benth.) Nielsen) has antioxidant activity because it contains flavonoid compounds, saponins, and alkaloids, so jengkol skin can be used as a facial treatment. The peel off mask preparation was chosen because is one type of cosmetic that is easy to use because it utilizes the ability to release the film layer when applied to the skin so that it can increase comfort in use and is expected to increase the antioxidant activity of jengkol skin extract. Components of masks such as PVA (Polyvinyl Alcohol) which act as filming agents, affect the physical properties of the mask, because it is the material underlying the peel off mask. A stability test needs to be carried out to ensure the durability of the mask during storage. This study aims to determine the stability and antioxidant activity of peel off masks of jengkol skin from various concentrations of PVA. The method used is maceration with 70% ethanol solvent. PVA was used with concentrations of 6%, 8% and 10%. The physical properties test includes organoleptic test, pH test, homogenity test, adhesion test, dispersion test, dry time test, and viscosity test. The antioxidant test of peel off mask preparations was carried out by DPPH method (1,1 Difenyl-2-picrylhydrazil). Based on the results of the study, it was obtained that the peel off mask preparation was stable for a maximum of 21 days of storage. Formula with a PVA concentration of 10% is the formula that has the best physical properties during storage but is the most unstable formula because there are more white lumps than other formulas on the 28th day. The IC50 values ??were 420.9 ?g/mL, 397.4 ?g/mL and 434.1 ?g/mL

Formulasi Dan Uji Stabilitas Masker Gel Peel-Off Ekstrak Etanol Daun Belimbing Wuluh Dengan Variasi Konsentrasi Pva

“…Uji waktu mengering Sebanyak 0,5 gram sediaan dioleskan ke punggung tangan dengan panjang 7 cm dan lebar 7 cm. Amati waktu yang diperlukan sediaan untuk mengering, yaitu waktu dari awal dioleskan hingga terbentuk lapisan kering (Nabila et al, 2020).…”

“…Masker peel off memiliki bahan utama seperti filming agent yang akan membentuk lapisan film tipis saat masker diaplikasikan pada kulit, seperti PVA (Rizal et al, 2016). Masker peel off diformulasikan dengan zat aktif berupa kombinasi daun sirih hijau dan buah belimbing wuluh, basis PVA, pengawet, pelembab, dan pewangi (Nabila et al, 2020). PVA berfungsi sebagai filming agent sabgat berpengaruh terhadap parameter kecepatan pengeringan masker peel off.…”

Studi Literatur: Pengaruh Konsentrasi PVA dan HPMC Terhadap Sifat Fisik dan Stabilitas Fisik Masker Gel Peel-Off dari Bahan Alam

“…Film forming ini memiliki fungsi untuk memberikan efek mengelupas saat masker dibersihkan. Sifat yang dimiliki oleh PVA yakni mudah larut dalam air, mudah dibentuk menjadi film yang tidak beracun, memiliki kestabilan mekanik dan fleksibel [4]. Selain itu, dilakukannya juga penambahan Hydroxypropyl methylcellulose (HPMC) yang berfungsi sebagai gelling agent.…”
