Triisononanoin, also known as Propane-1,2,3-triyl 3,5,5-trimethylhexanoate, is a versatile ingredient commonly found in various cosmetic products. This compound is a type of ester, which is formed through the reaction of an alcohol and an acid. Specifically, Triisononanoin is derived from glycerin (a trihydroxy alcohol) and isononanoic acid (a branched-chain fatty acid). Its chemical structure allows it to function effectively in skincare formulations.
The history of Triisononanoin in cosmetics dates back to the increasing demand for multifunctional ingredients that can enhance the texture and performance of skincare products. Initially, cosmetic chemists were on the lookout for compounds that could provide both skin conditioning and viscosity controlling properties. Triisononanoin emerged as a suitable candidate due to its unique chemical composition and beneficial attributes.
The production of Triisononanoin involves a process called esterification, where glycerin reacts with isononanoic acid under controlled conditions. This reaction results in the formation of a stable ester that can be easily incorporated into various cosmetic formulations. The end product is a clear, odorless liquid that blends seamlessly with other ingredients, making it a popular choice among formulators.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Triisononanoin:
Triisononanoin is primarily used as a skin conditioning agent. This means it helps to keep your skin soft, smooth, and hydrated. When applied in cosmetic products, it forms a thin layer on the skin’s surface, which helps to lock in moisture and prevent dryness. This can be particularly beneficial for individuals with dry or sensitive skin, as it helps to maintain a healthy skin barrier and improve overall skin texture.
Another key function of Triisononanoin is its role in controlling the viscosity of cosmetic formulations. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, Triisononanoin ensures that creams, lotions, and other cosmetic products have the right consistency for easy application and absorption. This makes the products more user-friendly and enhances their overall performance.
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).
Triisononanoin is generally considered safe for use in cosmetic products, with a low risk of causing adverse reactions. However, as with any ingredient, there are potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Triisononanoin 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 Triisononanoin are uncommon, but it is always prudent to perform a patch test before widespread usage to ensure personal compatibility.
Triisononanoin has a comedogenic rating of 1, which means it is unlikely to clog pores and cause acne or breakouts. This makes it a suitable option for individuals prone to acne or blemishes, although individual reactions can vary.
