Glycereth-7 Lactate is a unique cosmetic ingredient that combines the benefits of lactic acid and glycerin. Chemically, it is the ester of lactic acid and a polyethylene glycol ether of glycerin, containing an average of 7 moles of ethylene oxide. This complex composition allows it to serve dual functions in cosmetic formulations: as a skin conditioning agent and a solvent.
The ingredient is sometimes referred to by other names, such as PEG-7 Glyceryl Lactate, reflecting its chemical structure. The use of Glycereth-7 Lactate in cosmetics has evolved over time, driven by the need for multifunctional ingredients that can enhance the performance of skincare products. Its ability to condition the skin while also acting as a solvent makes it a valuable addition to many formulations.
The production of Glycereth-7 Lactate involves a chemical reaction between lactic acid and a polyethylene glycol ether of glycerin. This process results in a compound that can effectively blend with other ingredients, improving the overall texture and efficacy of the final product. Its versatility and beneficial properties have made it a popular choice among cosmetic chemists and formulators.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Glycereth-7 Lactate:
Glycereth-7 Lactate is primarily used for its skin conditioning properties. This means it helps to maintain the skin in good condition. In simpler terms, it can make your skin feel softer, smoother, and more hydrated. When included in skincare products, it helps to improve the overall texture and appearance of the skin, making it look healthier and more radiant.
Another key function of Glycereth-7 Lactate is its role as a solvent. In the context of cosmetics, a solvent helps to dissolve other ingredients, making it easier to create a uniform and stable product. This ensures that the active ingredients in your skincare products are evenly distributed, allowing for more effective application and absorption. Essentially, it helps to keep the product’s formula consistent and effective.
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-7 Lactate 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-7 Lactate during pregnancy are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice.
Side effects and adverse reactions from Glycereth-7 Lactate are relatively uncommon. However, it is always a good practice to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
On a comedogenicity scale of 0 to 5, Glycereth-7 Lactate is rated as a 0, meaning it is considered non-comedogenic. This makes it suitable for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores.
