Glycereth-18 Benzoate is a synthetic ingredient commonly used in cosmetic formulations. It is the ester of Benzoic Acid and a polyethylene glycol ether of Glycerin, containing an average of 18 moles of ethylene oxide. This complex chemical composition allows it to function effectively as a skin conditioning agent and solvent in various beauty and personal care products.
The history of Glycereth-18 Benzoate in cosmetics dates back to the increasing demand for multifunctional ingredients that can enhance the texture and stability of formulations. Over time, it has become a popular choice among formulators due to its ability to improve the feel and spreadability of products on the skin.
The production of Glycereth-18 Benzoate involves a chemical reaction between Benzoic Acid and a polyethylene glycol ether of Glycerin. This process, known as esterification, results in a compound that combines the beneficial properties of both parent ingredients. The inclusion of ethylene oxide units enhances its solubility and compatibility with other cosmetic ingredients, making it a versatile addition to a wide range of products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Glycereth-18 Benzoate:
Glycereth-18 Benzoate is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its appearance and texture. When used in cosmetic formulations, it can make your skin feel softer, smoother, and more hydrated. Essentially, it acts as a moisturizer, helping to keep your skin supple and preventing dryness. This is particularly beneficial in products like lotions, creams, and serums where skin hydration is a key benefit.
Another important function of Glycereth-18 Benzoate is its role as a solvent. In the world of cosmetics, a solvent is a substance that dissolves other ingredients, making it easier to create a uniform and stable product. By acting as a solvent, Glycereth-18 Benzoate helps to evenly distribute active ingredients throughout the formulation, ensuring that each application delivers consistent results. This is crucial for products like cleansers, toners, and makeup, where a smooth and even application is desired.
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).
Glycereth-18 Benzoate is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Glycereth-18 Benzoate during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Side effects and adverse reactions from Glycereth-18 Benzoate are generally uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that you do not have a sensitivity or allergic reaction to the ingredient.
In terms of comedogenicity, Glycereth-18 Benzoate has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means that it is unlikely to clog pores, making it suitable for people who are prone to acne, blemishes, or breakouts.
