What Is Guaiene?

Guaiene, also known by its chemical name (1S-cis)-1,2,3,4,5,6,7,8-Octahydro-7-isopropylidene-1,4-dimethylazulene, is a naturally occurring sesquiterpene hydrocarbon. This compound is primarily sourced from the essential oils of various plants, particularly those belonging to the Guaiacum species. It is also sometimes referred to as guaiazulene, although this term can also denote a closely related compound.

The history of guaiene in cosmetics dates back to the early exploration of essential oils and their aromatic properties. Over time, as the fragrance industry evolved, guaiene was identified for its unique scent profile, which is often described as woody, spicy, and slightly sweet. This discovery led to its incorporation into various perfuming products, where it serves as a key ingredient in creating complex and appealing fragrances.

The production of guaiene typically involves the extraction of essential oils from plant sources through steam distillation or cold pressing. Once the essential oil is obtained, guaiene is isolated and purified using techniques such as fractional distillation. This process ensures that the final product is of high purity and suitable for use in cosmetic formulations.

The Benefits/Uses of Guaiene

In this section, we will delve into the officially recognized cosmetic benefits and uses of Guaiene:


Guaiene is primarily used in cosmetics for its perfuming properties. This means it is added to products to impart a pleasant fragrance. Whether it’s a luxurious lotion, a refreshing body wash, or a sophisticated perfume, Guaiene helps to create an appealing scent profile that enhances the overall sensory experience of the product. The unique aroma of Guaiene can make a product more attractive and enjoyable to use, contributing to a sense of well-being and personal satisfaction.

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).

Guaiene is generally considered safe for use in cosmetic products, particularly in its role as a perfuming agent. However, as with any ingredient, there are potential side effects and considerations to keep in mind.

  • Allergic reactions
  • Contact dermatitis

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Guaiene during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.

Side effects and adverse reactions from Guaiene are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that you do not have an adverse reaction to the ingredient.

In terms of comedogenicity, Guaiene has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means that Guaiene is unlikely to clog pores or cause acne, making it suitable for individuals prone to blemishes and breakouts.
