Phenylethylidene-Bis-Indole, also known as 1,1′-(2-Phenylethylidene)bis(1H-indole), is a synthetic compound that’s primarily used in the cosmetics industry for its perfuming properties. This ingredient is not naturally derived and doesn’t have any other common names. Its chemical structure consists of two indole groups, which are organic compounds, linked by a phenylethylidene group.
The use of Phenylethylidene-Bis-Indole in cosmetics is relatively recent, and it’s primarily found in fragrances and perfumed skincare products. Its unique aromatic properties make it a valuable addition to a variety of cosmetic formulations. It’s worth noting that this ingredient doesn’t have any known therapeutic benefits, and its sole function is to add a pleasant scent to products.
The production of Phenylethylidene-Bis-Indole involves a series of chemical reactions. First, indole is reacted with phenylethylidene in the presence of a catalyst to form a complex intermediate. This intermediate is then further reacted to form the final product, Phenylethylidene-Bis-Indole. The entire process is carried out in a controlled environment to ensure the purity and quality of the final product.
In this section, we will delve into the officially recognized benefits and uses of Phenylethylidene-Bis-Indole:
Phenylethylidene-Bis-Indole is primarily used in cosmetics for its perfuming properties. This means that it is used to impart a specific scent to the product. The scent of a cosmetic product plays a crucial role in the overall user experience. It can make the product more appealing to use and can also enhance the mood of the user. The scent can also mask the smell of other ingredients that may not be as pleasant. Phenylethylidene-Bis-Indole is a versatile ingredient that can be used in a wide range of cosmetic products, from skincare and hair care products to makeup and perfumes.
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).
Phenylethylidene-Bis-Indole, while primarily used for its perfuming properties, is generally considered safe for topical use in cosmetics. However, as with any ingredient, individual reactions can vary and there is always a potential for side effects. These may include:
Regarding individuals who are pregnant or breastfeeding, there is currently insufficient data on the safety of topical use of Phenylethylidene-Bis-Indole during pregnancy or lactation. As such, it is recommended to consult a healthcare professional for further advice.
While adverse reactions to Phenylethylidene-Bis-Indole are not common, it is always recommended to perform a patch test before widespread usage. This can help identify any potential sensitivity or allergic reaction to the ingredient.
As for its comedogenicity, Phenylethylidene-Bis-Indole is rated as 2 on a scale of 0 to 5. This means it has a moderate likelihood of clogging pores, which could potentially lead to acne or blemishes in individuals with acne-prone skin. Therefore, if you are prone to breakouts, it may be worth considering products that do not contain this ingredient.
