Zwitterionic comb-like lipid polymers encapsulating linalool for increasing the fragrance retention time

Fragrances are widely used in cosmetics, apparel and detergents. However, the rapid evaporation of the aroma shortens the useful life of the aromatic product. Therefore, improving the fragrance retention time of aromatic products and prolonging the service life of aromatic products are the key scientific problems that need to be solved in current aromatic products. In this study, zwitterionic comb-like lipid polymers were synthesized to encapsulate the fragrance molecule linalool. The results showed that the zwitterionic comb lipid molecules were capable of encapsulating more linalool than linear lipid molecules. At the same time, the zwitterionic comb-like lipid molecules also limited the slow release rate of the aroma, thereby increasing the fragrance retention time of the nano-fragrance.
