Formulation of marigold (Tagetes erecta L.) flower extract in peel off mask using polyvinyl alcohol and polyethylene glycol 6000 base

Abstract

Flavonoids and carotenoids in marigold flower extract can act as a potent antioxidant. Because the use of antioxidant peel-off face masks is efficient, this research aimed to determine the effect of marigold (Tagetes erecta L.) extract, formulated with Polyvinyl Alcohol (PVA) and Polyethylene Glycol (PEG) 6000 as the bases, on the physical characteristics and stability of the produced peel-off face masks. This formulation used the ethanol extract of the marigold flower with three different concentrations, namely F1 3%, F2 4%, and F3 6%. The masks were then evaluated for their physical features (organoleptic, homogeneity, viscosity, spreadability, and drying time), chemical characteristic (pH), and stability. The results showed that all of the three formulas created a brown, soft textured, and homogeneous gel. Further tests revealed that F1, F2, and F3 differed in viscosity (18.466; 22.533; 28.133cps), drying time (29.1; 26.29; 24.64 minutes), pH (5.5I; 4.71; 4.59), and spreadability (6.7; 6.5; 5.9 cm) although not significantly. Based on both stability and freeze-thaw tests, these formulas were concluded as stable without any significant changes in their organoleptic properties and pH levels. Prepared with PVA and PEG 6000 as the bases, marigold extract can form peel-off face masks with good stability and physical features when used up to 6% concentration in the formulation.
