Biotechnological Strategies to Enhance Fragrance Longevity and Sustainability: Focus on Bio‐Based Materials and Green Technologies—A Review

ABSTRACT This review aims to discover biotechnological strategies applicable to both natural and synthetic fragrances for enhancing longevity and sustainability, addressing the challenge of limited scent duration in personal care products. A comprehensive literature review was conducted, analysing advancements in bio‐based substances, enzymatic technologies, nanotechnology, microbial biosynthesis, microencapsulation, and genetic engineering. Key findings consist of the use of biodegradable polymers (e.g., alginate, polylactic acid) for sustained perfume launch, metagenomic enzymes (e.g., Est16, Lip‐1420) for stabilising compounds, and CRISPR‐based genetic engineering for greater terpenoid biosynthesis. Nanotechnology and microencapsulation shield high‐risk compounds, while microbial methods offer scalable, eco‐friendly production. Biotechnological innovations provide sustainable, high‐performance answers for fragrance formulations, with promising implications for enterprises and environmentally conscious clients.
