Glyceryl/Erythorbyl Laurates is a unique cosmetic ingredient that combines glycerin and erythorbic acid with lauric acid through a process known as mixed esterification. This ingredient is also known by other names, such as Glyceryl Laurate and Erythorbyl Laurate, reflecting its composite nature. Chemically, it is a mixed ester, meaning it is formed from the reaction of multiple alcohols (glycerin and erythorbic acid) with a fatty acid (lauric acid).
The history of Glyceryl/Erythorbyl Laurates in cosmetic products is relatively recent, emerging as a multifunctional ingredient that offers both skin conditioning and skin protecting benefits. Initially, glycerin and lauric acid were used separately in various skincare formulations for their moisturizing and antimicrobial properties, respectively. Erythorbic acid, a stereoisomer of Vitamin C, was also recognized for its antioxidant properties. The combination of these components into a single esterified product was driven by the need for more efficient and multifunctional ingredients in modern skincare formulations.
The production of Glyceryl/Erythorbyl Laurates involves a chemical process called esterification. In this process, glycerin and erythorbic acid are reacted with lauric acid in the presence of a catalyst. This reaction results in the formation of ester bonds, creating a compound that retains the beneficial properties of its individual components while enhancing their stability and efficacy. The resulting product is a versatile ingredient that can be easily incorporated into various cosmetic formulations, providing both conditioning and protective benefits to the skin.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Glyceryl/Erythorbyl Laurates:
Glyceryl/Erythorbyl Laurates is 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 products, it can make your skin feel softer, smoother, and more hydrated. Essentially, it acts as a moisturizer that helps to keep your skin looking and feeling healthy.
Another key benefit of Glyceryl/Erythorbyl Laurates is its ability to protect the skin. This ingredient forms a barrier on the skin’s surface, which can help to shield it from environmental stressors such as pollution and harsh weather conditions. By providing this protective layer, it helps to prevent damage and maintain the skin’s natural integrity.
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).

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Glyceryl/Erythorbyl Laurates during pregnancy and breastfeeding 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 Glyceryl/Erythorbyl Laurates are uncommon, but it is always prudent to perform a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, Glyceryl/Erythorbyl Laurates 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 indicates that it is unlikely to clog pores, making it generally suitable for people prone to acne, blemishes, or breakouts.
