Zwaardemaker Pairs

An important contribution of Zwaardemaker's studies is the concept of odor conjugates. Zwaardemaker discovered that certain odors could be prevented from detection by smell senses when mixed with various essential oils. These combination of odors are referred to as Zwaardemaker Pairs, (or Z-pairs).
