Trilinolein, also known by its chemical name Propane-1,2,3-triyl tris[(9Z,12Z)-octadeca-9,12-dienoate], is a triglyceride composed of three linoleic acid molecules attached to a glycerol backbone. This ingredient is primarily sourced from plant oils, such as sunflower, safflower, and soybean oils, which are rich in linoleic acid.
The use of Trilinolein in cosmetics has a relatively modern history. As the demand for natural and plant-derived ingredients grew, researchers and formulators began to explore the benefits of various fatty acids and their derivatives. Linoleic acid, being an essential fatty acid with numerous skin benefits, became a focal point. Trilinolein emerged as a valuable ingredient due to its ability to deliver linoleic acid in a stable and effective form.
The production of Trilinolein involves the esterification of glycerol with linoleic acid. This process typically occurs in a controlled laboratory setting where glycerol is reacted with linoleic acid in the presence of a catalyst. The result is a triglyceride that combines the moisturizing and skin-conditioning properties of linoleic acid with the structural benefits of glycerol. This makes Trilinolein a versatile ingredient in various cosmetic formulations, from creams and lotions to serums and oils.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Trilinolein:
Trilinolein is known for its skin conditioning properties. This means it helps to keep your skin soft, smooth, and healthy. When applied in cosmetic products, it can enhance the overall texture and appearance of your skin, making it feel more supple and hydrated. This is particularly beneficial for those with dry or rough skin, as it can provide much-needed moisture and nourishment.
Another key benefit of Trilinolein is its ability to control the viscosity of cosmetic formulations. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, Trilinolein ensures that creams, lotions, and other cosmetic products have the right consistency for easy application and absorption. This means your favorite skincare products won’t be too runny or too thick, making them more pleasant and effective to use.
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).
Trilinolein 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 Trilinolein 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 Trilinolein are relatively uncommon, but it is always recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
Trilinolein has a comedogenic rating of 2, which means it has a low to moderate likelihood of clogging pores. People who are prone to acne, blemishes, or breakouts should take this into consideration when choosing products containing this ingredient.
