Product Introduction

Glycereth-10 laurate, a polyethylene glycol ether of glycerol monolaurate, functions primarily as a surfactant and emulsifier in cosmetic formulations [1]. It is derived from the esterification of lauric acid, a fatty acid, with polyglycerol, specifically a polymer of 10 glycerol units, followed by ethoxylation [2]. This ethoxylation process enhances its water solubility, making it suitable for various aqueous cosmetic products [3]. The compound is known for its mildness and low irritation potential, rendering it useful in products designed for sensitive skin [4].

Production Process

The production of glycereth-10 laurate typically involves a multi-step process. First, lauric acid, often sourced from coconut or palm kernel oil, undergoes esterification with glycerol to form glycerol monolaurate [5]. Next, this glycerol monolaurate is reacted with ethylene oxide in the presence of a catalyst, such as an alkaline catalyst, to achieve the desired degree of ethoxylation, resulting in glycereth-10 laurate [6]. The reaction is carefully controlled to ensure the incorporation of approximately 10 ethylene oxide units per molecule [7]. Finally, the product is purified to remove any unreacted materials and by-products [8].

Efficacy and Function

Glycereth-10 laurate acts as an effective emulsifier by reducing the surface tension between aqueous and oily phases, thereby stabilizing emulsions [9]. As a solubilizer, it helps to incorporate oil-soluble ingredients into water-based formulations, ensuring a clear and homogenous product [10]. Additionally, it provides emollient properties, contributing to skin softness and hydration [11]. Its mildness allows for use in facial cleansers, lotions, and shampoos without causing significant irritation [12].

Application Scenarios

This ingredient finds widespread use in various cosmetic and personal care products. In facial cleansers and body washes, glycereth-10 laurate helps to remove dirt and oil while maintaining skin hydration [13]. It is also included in lotions and creams as an emulsifier and emollient, promoting a smooth and moisturized skin feel [14]. Shampoos and conditioners benefit from its solubilizing properties, aiding in the even distribution of fragrance oils and conditioning agents [15]. Its presence is also noted in baby products due to its gentle nature [16].

Packaging and Transportation

Glycereth-10 laurate is commonly packaged in plastic drums or containers, ensuring the material's integrity during storage and transit [17]. Transportation adheres to standard practices for non-hazardous materials, avoiding extreme temperature conditions to maintain stability [18]. Containers are typically sealed to prevent contamination and moisture absorption [19]. Proper labeling includes manufacturing date, batch number, and storage instructions [20].
