Potential use of Polyphenol-Enriched Extract from Moringa oleifera Leaves as an Active Ingredient in Sunscreen

Abstract

Moringa oleifera is commonly referred to as the “tree of life” due to its high nutrient content and valuable biological activities. Widely found in tropical zones, this plant is usually used in local cuisine, cosmetic products and nutraceuticals. In this paper, we explored the potential of Moringa oleifera leaf alcoholic extract as a bioactive ingredient in sunscreen. Characterizations of extract were firstly investigated, including total polyphenol content, antioxidant activity. Formulations of extract containing creams were then created in order to examine its ability to protect against UVB radiation in the presence of other ingredients. Various evaluations of cream were carried out, including stability testing, UV absorption capacity, in vitro SPF values and microbial testing. The results revealed that Moringa oleifera extract showed a promising active ingredient in sunscreen, with a moderate antioxidant activity. Cream containing 2% of extract incorporated with 2% of oxybenzone demonstrated good in vitro SPF values.
