Geraniol

Geraniol is a fragrant liquid unsaturated alcohol (C10H18O) used primarily in perfumes and soap[1]. It is an acyclic isoprenoid monoterpene isolated from the essential oils of aromatic plants, including Cinnamomum tenuipilum and Valeriana officinalis[2]. Geraniol has a rose-like scent and is commonly used in perfumes and flavors such as peach, raspberry, grapefruit, red apple, plum, lime, orange, lemon, watermelon, pineapple, and blueberry[3]. It is the primary part of rose oil, palmarosa oil, and citronella oil (Java type), and also occurs in small quantities in geranium, lemon, and many other essential oils[3].

Geraniol is recognized as safe by the International Fragrance Association Codes & Standards for use in cosmetics and personal care products at a concentration of ≥90%[4]. However, it can be a possible cause for allergic contact dermatitis, and individuals should check with their doctor before using any new products to ensure this ingredient isn't an irritant for their skin[4]. The Food and Drug Administration (FDA) designates geraniol as a safe food additive, and it's also recognized as safe by the Flavor and Extract Manufacturers Association (FEMA)[4]. As a natural ingredient, geraniol is biodegradable and has a low level of bioaccumulation, making it safe for the environment[4].

Geraniol is a common fragrance ingredient that smells like rose and can be found in rose oil or in small quantities in geranium, lemon, and many other essential oils[5]. However, it can oxidize on air exposure and become allergenic, so it's best to avoid if you have sensitive skin[5].
