Xymenynic Acid, also known by its chemical name 11-Octadecen-9-ynoic acid, (E)-, is a naturally occurring fatty acid primarily sourced from the seeds of the Santalum album, commonly known as sandalwood. This ingredient is also referred to as Santalbic Acid in some contexts. Chemically, it is an unsaturated fatty acid with a unique triple bond, which sets it apart from more common fatty acids found in cosmetic formulations.
The history of Xymenynic Acid in cosmetics is relatively recent, although its source, sandalwood, has been revered for centuries in traditional medicine and perfumery. The extraction and identification of Xymenynic Acid from sandalwood seeds opened new avenues for its application in skincare products. Researchers discovered its potential benefits for skin conditioning and emollient properties, leading to its inclusion in various cosmetic formulations.
The production of Xymenynic Acid involves the extraction of oil from sandalwood seeds, followed by a series of purification processes to isolate the fatty acid. This ensures that the final product is of high purity and suitable for use in cosmetic applications. The extraction process is designed to maintain the integrity of the acid, preserving its beneficial properties for skin care.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Xymenynic Acid:
Xymenynic Acid is known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When applied in cosmetic formulations, it can improve the appearance and feel of the skin, making it softer, smoother, and more supple. Essentially, it works to keep your skin looking and feeling its best by providing essential care and nourishment.
Another key benefit of Xymenynic Acid is its role as an emollient. Emollients are substances that soften and moisturize the skin, reducing dryness and flakiness. By forming a protective barrier on the skin’s surface, Xymenynic Acid helps to lock in moisture, preventing water loss and keeping the skin hydrated. This can be particularly beneficial for individuals with dry or sensitive skin, as it helps to soothe and protect the skin from environmental stressors.
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).
Xymenynic Acid is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Xymenynic Acid 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.
Side effects and adverse reactions from Xymenynic Acid are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that the ingredient does not cause any adverse reactions on your skin.
In terms of comedogenicity, Xymenynic Acid is rated as a 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating means that it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
