NEOS: an odor-induced affect scale for use in the cosmetic industry.

This work proposes an odor-induced affect scale for use in the cosmetic industry that relies on the approach that produced the UniGEOS, a universal odor-related emotional scale from the Swiss Center for Affective Sciences. The Natura Emotion and Odor Scale (NEOS) was built on experiments conducted with a larger set of participants (491) and a set of 35 scents that combine seven commercial perfumes from Natura & Co cosmetic company with 28 odors from different olfactory classes important for the cosmetic industry. The results showed the stability of 60 Emotion-Related terms in Brazilian Portuguese split into five emotion-related dimensions: Romance, Attention, Energy, Well-Being and Negative feelings. The association of the scents evoking these five dimensions has direct implications in the design of new products.
