Product Introduction

Glycerol polyether-7, also known as Glycereth-7, is a polyethylene glycol ether of glycerin. It is a non-ionic surfactant, widely used in the cosmetic industry, because of its moisturizing and solubilizing capabilities. Glycereth-7 is soluble in water and alcohol. This product is favored for its mildness and compatibility, making it suitable across diverse personal care formulations [1].

Production Process

The production of Glycereth-7 typically involves the ethoxylation of glycerin, where ethylene oxide is reacted with glycerin in the presence of a catalyst. This process results in the addition of an average of seven ethylene oxide units to the glycerin molecule [2]. The reaction is carefully controlled to ensure the desired degree of ethoxylation, achieving consistency in the final product's properties. Post-reaction, the mixture undergoes neutralization and purification steps, removing any residual reactants and by-products to obtain high-purity Glycereth-7 suitable for cosmetic applications [3].

Efficacy and Function

Glycereth-7 serves primarily as an emollient and humectant. As an emollient, it helps to soften and smooth the skin by filling in gaps between skin cells with lipids, thus improving skin texture [4]. As a humectant, Glycereth-7 attracts moisture from the air and draws it into the skin, keeping the skin hydrated [5]. Additionally, it functions as a solvent and viscosity modifier in cosmetic formulations, ensuring uniform product consistency and enhancing the solubility of other ingredients [6].

Application Scenarios

Glycereth-7 finds applications in a variety of cosmetic and personal care products. It is commonly used in skin care formulations, such as lotions, creams, and serums, where its moisturizing and softening properties are highly valued [7]. In hair care products, like shampoos and conditioners, it acts as an emollient and helps to improve hair manageability [8]. It is also used in cleansing products, such as body washes and facial cleansers, for its mildness and ability to solubilize oils and dirt [9].

Packaging and Transportation

Glycereth-7 is typically packaged in plastic drums or containers, with sizes ranging from small containers for laboratory use to large drums for industrial applications. During transportation, containers are secured to prevent leakage and damage, maintaining the integrity of the product [10]. It should be stored in cool, dry conditions away from direct sunlight and heat to prevent degradation. Standard safety measures are implemented during handling and transportation in compliance with regulatory guidelines [11].
