In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular we have explored the surface delivery of the model perfumes phenyl ethanol, PE, and Linalool, LL, with the anionic surfactant LAS, and the alkyl sulphates such as SDS. These initial results illustrate the importance of the structure of the perfume molecule which dictates its location at the interface and moderates specific perfume-surfactant interactions which can enhance coadsorption. We propose to test these concepts by exploring a wider range of model perfumes with distinctly different structures and degrees of hydrophobicity by studying the coadsorption of Eugenol and Limonene with SDS at the air-water interface.
