A fragrance concentration refers to the strength that a fragrance has. Perfumes with a higher fragrance concentration contain more perfume oils and less alcohol. Fragrance concentrations are broken into categories.
Deodorant
A deodorant is a substance applied to the body to prevent or mask (hide) body odor due to bacterial breakdown of perspiration in the armpits, groin, and feet, and in some cases vaginal secretions. A subclass of deodorants, called antiperspirants, prevents sweating itself, typically by blocking sweat glands.
PERFUME
A perfume has three types of notes, a top note, a middle note, and a base note. A top note is the first scent you 'experience' when you first apply the fragrance. Top notes include and can be referred as citrusy, summery, woody, spicy, or floral.
