Pinene
What is Pinene?
Pinene is a natural organic compound found in the oils of many coniferous trees, particularly pines. It exists in two structural forms, alpha and beta pinene, each with distinct chemical properties.
Pinene is often used in fragrances and as a flavoring agent due to its fresh, pine-like aroma. Some studies suggest that pinene may have anti-inflammatory and bronchodilator properties, though the evidence is not conclusive. It is also being investigated for potential antimicrobial benefits.
When included in products, pinene is typically part of a blend of natural aromas. For consumers sensitive to fragrances, it might be a potential irritant in high concentrations, but standard usage levels are generally considered safe.
Commonly found in: Perfumes, Essential Oils, Aromatherapy Products, Cleaning Products, Food Flavoring
What to watch

Pine-terpene aromachemical. Oxidizes on air exposure into stronger sensitizers (alpha-pinene hydroperoxides are documented contact allergens).
