Heretic Dirty Vanilla Eau de Parfum What is Limonene?
Limonene is a naturally occurring compound found in the peels of citrus fruits. It is a hydrocarbon classified as a cyclic monoterpene and is typically extracted through cold-pressing or steam distillation methods.
Limonene is commonly used in consumer products for its pleasant citrus scent and its ability to dissolve oils, making it a popular choice in fragrances, personal care, and cleaning products. While limonene is generally recognized as safe (GRAS) when used in food, some studies have shown it can cause skin irritation in certain individuals.
When you see limonene on a label, it's often used for its scent rather than any significant function in the product. Although deemed safe for most, individuals with citrus allergies or sensitive skin should proceed with caution.
Commonly found in: Deodorant, Lip Care, Fragrances, Dishwasher, Hand Sanitizer
