Abstract
Peel off mask has been very popular and preferred due to its ease in application. Gel base has been preferred for its cold and moist sensation during application. When herbal ingredients such as extract is introduced into gel formulation, the stability then will become an issue. The aim of the study was to formulate the peel-off mask gels containing green tea leaves extract (Camellia sinensis L.) which effective, stable, and safe to be used. The antioxidant study was conducted by using Diphenylhydrazylpicryl (DPPH) method. The peel-off mask gel formula were Hidroxypropyl Methylcelulosa (HPMC) as gel base at 0.5% concentration and plasticizer Polyvinyl Alcohol (PVA) at concentration of 12%. Evaluation of peel-off mask gel included observation on pH, viscosity, dispersing power, and drying time during the 90 days of storage at room temperature. The IC50 values of the green tea (Camellia sinensis L.) extract was 5.511 ppm. The concentration of green tea leaves extract in the preparation were 1x IC50 (F1); 2x IC50 (F2) and 3x IC50 (F3). The result showed that all preparations were stable in the aspect of consistency, color, and odor. Viscosity, drying time and dispersing power remained unchanged after 90 days of storage. The pH value changed, but still in the range of acceptable pH of topical preparations. The results of antioxidant activity study showed that formula F3 (peel-off mask gels with 3 x IC50 of green tea extracts) had the highest antioxidant activity.Keywords: antioxidant, Camellia sinensis L., peel off gel masks, green tea
Highlights
Aging skin can be inhibited by using cosmetics that contain antioxidants
It can be concluded that the extract contain flavonoid, alkaloid and many other biological compound which responsible to its activity as antioidant
The results of the moisture content determination of green tea leaves extract was 0.83%. This result was in the range of the quality, which should not be more than 10%, in order to avoid microbial growth especially fungus on the extracts
Summary
Aging skin can be inhibited by using cosmetics that contain antioxidants. Antioxidants can reduce free radicals to be less reactive molecules, it can avoid and reduce oxidative damage. The use of antioxidants in anti-aging skin care is essential to prevent further skin damage[1]. Antioxidants are grouped into two categories based on the source, which is an antioxidant that is naturally and synthetically derived[2]. The concerns about possible side effects that are not known from synthetic antioxidants cause natural antioxidant potential alternatives to be developed[2]. Epigallocatechin gallate (EGCG) and epicatechin gallate (ECG) are types of major catechins in green tea.
