The Hydroperoxides of Linalool and Limonene

Linalool is a naturally occurring terpene alcohol chemical found in many flowers and spice plants with many commercial applications, the majority of which are based on its pleasant scent.
Limonene takes its name from the lemon, as the rind of the lemon, contains considerable amounts of this compound, which contributes to the odor.
Both fragrances are very common in cosmetic products, such as perfumes and creams. The hydroperoxides are formed when Limonene and Linalool are exposed to sunlight and air.
Now available as H-031 -Hydroperoxides of Linalool and H-032 -Hydroperoxides of Limonene
