Geranial, also known as (E)-3,7-Dimethylocta-2,6-dienal, is a naturally occurring compound found in the essential oils of several plants, most notably lemongrass, lemon balm, and other citrus fruits. It is also referred to as citral A, which is one of the two geometric isomers of citral, the other being neral (citral B). Geranial is a pale yellow liquid with a strong lemon scent, making it a popular choice in the fragrance industry.
Historically, geranial has been used for its pleasant aroma in various applications, including perfumes, soaps, and other personal care products. Its journey into the cosmetic world began with the extraction of essential oils from plants known for their aromatic properties. Over time, as the demand for natural and effective perfuming agents grew, geranial became a staple ingredient due to its potent and refreshing citrus fragrance.
The production of geranial typically involves the steam distillation of essential oils from plants like lemongrass. This process captures the volatile compounds, which are then separated and purified to obtain geranial. Advances in synthetic chemistry have also enabled the production of geranial through chemical synthesis, providing a more consistent and scalable supply for the cosmetic industry.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Geranial:
Geranial is primarily used in cosmetics for its perfuming properties. This means that it is added to products to impart a pleasant fragrance. The fresh, lemony scent of Geranial can enhance the sensory experience of using a cosmetic product, making it more enjoyable to apply. Whether it’s in a lotion, cream, or perfume, the inclusion of Geranial can make a product smell more appealing, which can be a significant factor in a consumer’s purchasing decision.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Geranial, while widely used for its perfuming properties, does come with certain considerations regarding its safety and suitability for all users.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Geranial during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Geranial are relatively uncommon, but they can occur, especially in individuals with sensitive skin or allergies. To minimize the risk of adverse reactions, it is recommended to conduct a patch test before widespread usage.
Geranial has a comedogenic rating of 1, which means it is considered to have a low likelihood of clogging pores. This makes it generally suitable for people who are prone to acne, blemishes, or breakouts. However, individual reactions can vary, so monitoring your skin’s response is always a good practice.
