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.
