Trioleyl Citrate, also known by its chemical name 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, tri-9-octadecenyl ester (all-Z)-, is a versatile ingredient commonly found in cosmetic products. This compound is derived from citric acid and oleic acid, both of which are naturally occurring substances. Citric acid is widely found in citrus fruits, while oleic acid is a monounsaturated fatty acid present in various plant oils, such as olive oil.
The use of Trioleyl Citrate in cosmetics has a relatively modern history. As the demand for more effective and multifunctional ingredients grew, researchers began to explore the potential of combining citric acid with fatty acids to create compounds that could offer multiple benefits. Trioleyl Citrate emerged as a promising candidate due to its ability to act as a plasticiser, skin conditioning agent, and emollient.
The production of Trioleyl Citrate involves a chemical reaction known as esterification. In this process, citric acid reacts with oleic acid in the presence of a catalyst, resulting in the formation of the ester compound. This reaction not only combines the beneficial properties of both acids but also enhances their stability and usability in various formulations. The end product is a highly functional ingredient that can be seamlessly incorporated into creams, lotions, and other personal care items.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Trioleyl Citrate:
Trioleyl Citrate acts as a plasticiser in cosmetic formulations. This means it helps to increase the flexibility and fluidity of the product, making it easier to apply and spread on the skin. Think of it as the ingredient that ensures your favorite lotion or cream has that smooth, glide-on texture, rather than feeling stiff or sticky.
One of the standout benefits of Trioleyl Citrate is its ability to condition the skin. This means it helps to maintain the skin’s softness, smoothness, and overall health. When you use a product containing this ingredient, you can expect your skin to feel more hydrated and nourished, which is especially beneficial for those with dry or rough skin.
As an emollient, Trioleyl Citrate plays a crucial role in moisturizing the skin. It works by forming a protective barrier on the skin’s surface, which helps to lock in moisture and prevent water loss. This makes it an excellent ingredient for keeping your skin feeling soft, supple, and hydrated throughout the day.
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).
Trioleyl Citrate is generally considered safe for use in cosmetic products, with a low potential for causing adverse reactions. However, as with any ingredient, there are some potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Trioleyl Citrate during pregnancy and breastfeeding 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 Trioleyl Citrate are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
In terms of comedogenicity, Trioleyl Citrate has a rating of 2 on a scale of 0 to 5. This means it has a low to moderate potential to clog pores, which could be a concern for individuals prone to acne, blemishes, or breakouts. Those with acne-prone skin should be cautious when using products containing this ingredient.
