From formulation to fibre
Four stages of fragrance deposition
The final impression emerges from a sequence of physicochemical transitions. None operates independently of the others.
How fragrance and water coexist
Fragrance materials do not become water-soluble through shaking alone. They need a suitable solubilisation system.
Micelles as an intermediate environment
Surfactants contain a region with affinity for water and another with affinity for less polar molecules. Above a characteristic concentration, they can organise into micelles, structures with regions of differing polarity into which fragrance materials partition. [1]
Tilghman et al. (2025) measured solubilisation of fragrance raw materials in Polysorbate 20 and SDS systems. Partitioning depended on the particular molecule, and one material could alter another’s solubilisation in binary mixtures. The behaviour of a complete fragrance mixture therefore cannot be predicted precisely from one material studied in isolation. [1]
The complete mixture is the unit of evaluation
The study measured partitioning equilibria in micellar solutions. It did not test the long-term stability of a finished fabric mist or pump repeatability. It does, however, show why solubilisation must be evaluated across the complete fragrance mixture. [1]
What a droplet does when it meets textile
Deposition is only the beginning. Spreading, imbibition, and evaporation follow.
A porous surface multiplies the path
On a flat non-porous surface, a droplet retains a relatively clear perimeter. In fabric, spaces between fibres create capillary pressure and draw liquid inwards. The final wetted area can become larger than the droplet’s initial footprint. [2]
Gonçalves et al. (2022) tracked water droplets on porous fabric with optical and X-ray imaging. Spreading and imbibition enlarged the wetted area and promoted evaporation. Because the study used water, it explains the aqueous-phase mechanism rather than the complete behaviour of every fabric mist. [2]
The study begins after deposition
Gonçalves et al. deposited a known volume of deionised water with a micropipette. The study supports the spreading, imbibition, and evaporation that follow deposition, not claims about pump design, spray distance, or spray angle. [2]
Why textiles retain fragrance differently
Fibre chemistry and fabric architecture shape both water movement and fragrance retention.
There is no universally most fragrant fibre
In direct fragrance tests, Du et al. (2020) found longer retention in samples with more cotton and linked it to water retention. In a realistic laundering study, Marcotullio et al. found greater overall retention of hydrophobic fragrance materials on polyester, while redeposition during rinsing was stronger on cotton. [3][4]
The findings are not contradictory. The studies examined different processes, direct application and laundering. They show that fibre cannot be interpreted without formulation, application route, and measurement stage. [3][4]
Fabric construction changes retention
In the Du experiments, twill retained fragrance longer than plain weave, and higher fabric density was also associated with longer retention. Porosity and capillary transport changed how quickly liquid dispersed and dried. [3]
What remains after drying
Fabric feels dry after losing sufficient moisture. Fragrance release can continue beyond that point.
Volatility and hydrophobicity change the path
In the Gherghel et al. study, lower-volatility compounds transferred and were recovered in larger amounts than higher-volatility compounds. In a different process, Marcotullio et al. linked hydrophobicity with greater overall retention of fragrance materials on polyester after laundering. Together, the experiments show that fragrance molecules do not all follow the same time course. [4][5]
Research on fragrance transfer between textiles detected volatile compounds even when scented fabric had aged for 48 hours before brief contact with a second fabric. The finding does not measure perceived intensity, but it confirms that some compounds can remain available after initial application. [5]
