TL;DR
This study explores using recycled palm oil in cosmetic creams, finding that it can be a sustainable ingredient with good performance and antimicrobial properties.
Contribution
The novelty lies in evaluating recycled palm oil's potential as a sustainable lipid phase in experimental cosmetic formulations.
Findings
Recycled palm oil retains structural features useful for topical formulations despite thermal degradation.
EM-R10 formulation showed better spreadability, adhesion, stability, and antimicrobial activity compared to R10.
Recycled palm oil is promising for sustainable cosmetics but requires further purification and safety testing.
Abstract
Sustainable strategies for revalorizing food industry by-products are increasingly relevant in the development of modern experimental dermato-cosmetic formulations. In this study, two semisolid cosmetic creams (R10 and EM-R10) were designed using recycled palm oil—physically purified after intensive frying—as the lipid phase. The recycled oil was incorporated strictly within a controlled experimental framework and does not imply cosmetic-grade regulatory compliance. The formulations incorporated distinct bioactive profiles: R10 combined apricot and pineapple extracts with lime essential oil, while EM-R10 integrated fir bud and green tea extracts alongside the same essential oil. Both preparations contained Fragard as a preservative and niacinamide and panthenol as vitaminic components. The physicochemical properties of the formulations were assessed through rheology, confocal…
