Comparing the Olfactory Perception of a Fragrance-Loaded SpECs Over Time
10 participantsStarted 2026-02-15
Plain-language summary
The human olfactory system plays a crucial role in sensory perception, influencing emotional states, memory, and interpersonal interactions(1). Fragrance durability and intensity are critical factors in the evaluation of perfumes and other scented products. The ability of fragrance formulations to maintain consistent scent intensity over time is a major contributor to a product's overall efficacy and consumer satisfaction,
Primary Aim To compare the perceived strength of a topical fragrance delivered via SpECs across a period of 8 hours using subjective ratings by participants and an independent examiner.
Objectives
1. To investigate whether the encapsulated fragrance intensity, as perceived by participants, decreases less over time compared with fragrance alone, after application to the skin.
2. To investigate whether the encapsulated fragrance intensity, as perceived by an independent examiner, decreases less over time compared with fragrance alone, after application to the skin.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
