Trihydroxystearin, also known by its chemical name 1,2,3-Propanetriyl tris(12-hydroxyoctadecanoate), is a versatile ingredient commonly found in various cosmetic products. This compound is derived from the esterification of glycerin and hydroxystearic acid, resulting in a molecule that boasts both skin conditioning and viscosity controlling properties. In simpler terms, it helps to keep your skin feeling soft and smooth while also ensuring that the product maintains a desirable consistency.
The use of Trihydroxystearin in cosmetics has a relatively modern history. As the cosmetic industry evolved, there was a growing demand for ingredients that could offer multifunctional benefits. Researchers and formulators identified Trihydroxystearin as a promising candidate due to its dual functionality. Its ability to condition the skin while also acting as a thickening agent made it an attractive addition to a wide range of products, from creams and lotions to makeup and hair care items.
The production of Trihydroxystearin involves a chemical process where glycerin, a naturally occurring compound, reacts with hydroxystearic acid. This reaction forms an ester, resulting in the final product. The process is carefully controlled to ensure the purity and effectiveness of the ingredient, making it suitable for use in various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Trihydroxystearin:
Trihydroxystearin is known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When applied in cosmetic formulations, it works to soften and smooth the skin, making it feel more supple and hydrated. This is particularly beneficial for those with dry or rough skin, as it can help to restore a more youthful and healthy appearance.
Another key function of Trihydroxystearin is its ability to control the viscosity of cosmetic products. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, Trihydroxystearin ensures that creams, lotions, and other formulations have the right consistency for easy application and absorption. This not only enhances the user experience but also ensures that the product delivers its active ingredients effectively.
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).
Trihydroxystearin 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 considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Trihydroxystearin during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from Trihydroxystearin are relatively uncommon. However, it is always a good practice to conduct a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
Trihydroxystearin has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals prone to acne, blemishes, or breakouts, as it is less likely to contribute to these skin issues.
