Development of an Eco-Friendly Acne Patch from Tannin Extract of Indian Almond Leaves and Silk Fibroin from Discarded Silkworm Cocoons
Keywords:

This study developed a sustainable acne patch using silk fibroin from discarded cocoons and tannin from Indian almond leaves. Tannin extract showed significant antibacterial activity against Cutibacterium acnes and Staphylococcus epidermidis comparable to standard antibiotics. The resulting composite patch demonstrated excellent mechanical properties including high elongation and optimal swelling ratios. Its water vapor transmission rate and surface pH aligned with medical wound dressing standards. These findings provide a scientific foundation for utilizing biowaste to create effective natural alternatives to synthetic antimicrobial treatments for acne management..
