Product Introduction

Glycereth-5 Lactate is a chemical compound created through the reaction of glycerin, a humectant, with lactic acid, an alpha-hydroxy acid, and further ethoxylation [1]. It functions primarily as a skin-conditioning agent and humectant in cosmetic formulations. It enhances the skin's moisture content and provides a smooth feel [2].

Production Process

The production of glycereth-5 lactate typically involves the ethoxylation of glycerin, followed by reaction with lactic acid. Ethoxylation introduces ethylene oxide units to the glycerin molecule, increasing its water solubility and changing its emollient properties. After ethoxylation to achieve a glycereth-5 intermediate, lactic acid is introduced under controlled conditions to form the final ester product. The reaction is carefully monitored to ensure the desired degree of esterification and to minimize the formation of unwanted by-products [3].

Efficacy and Function

Glycereth-5 lactate is valued for its dual function as a humectant and skin conditioner. As a humectant, it attracts moisture from the surrounding environment, helping to hydrate the skin. The lactate component provides mild exfoliation, contributing to smoother skin texture. It is also known to enhance the delivery of other active ingredients in cosmetic formulations due to its solvent properties [4].

Application Scenarios

Glycereth-5 lactate finds application in a variety of cosmetic products, including moisturizers, lotions, creams, and serums. It is used in formulations designed for dry or sensitive skin due to its moisturizing and mild exfoliating properties. It can also be found in hair care products, where it contributes to hydration and manageability [5].

Packaging and Transportation

Glycereth-5 lactate is typically packaged in plastic drums or containers suitable for liquid chemicals. These containers are designed to prevent leakage and maintain product integrity during transportation. Standard shipping procedures for non-hazardous chemicals are followed, ensuring that the product is protected from extreme temperatures and physical damage [6].
