The Formulation of The Peel off Gel Mask Preparation of Shallot Peel Extract (Allium cepa L.) As An Antioxidant

Shallot peel was known to contain secondary metabolites having the potential substances as antioxidants. This study aimed to determine whether shallot peel extract (Allium cepa L.) could be formulated into peel off gel mask preparation and to determine the antioxidant activity of the peel off gel mask preparation of shallot peel extract (Allium cepa L.). The method of this research was the extraction of shallot peel using the maceration method with methanol solvent. The extraction results obtained were made into a peel off gel mask preparation and tested for antioxidant activity with DPPH. The extraction results obtained was yield of 3.036%. The results of the evaluation of the peel off gel mask preparations obtained the peel off gel mask met the requirements and was stable in the formulation II with a concentration of 1% shallot peel extract. The results of the antioxidant activity test of the peel off gel mask obtained lC50 of 29.97% ppm.The antioxidant activity of the peel off gel mask shallot peel extract was included in the category of very strong antioxidant.
