Product Introduction

PEG-120 Methyl Glucose Sesquistearate is a polyethylene glycol derivative of a methyl glucose esterified with stearic acid. It functions primarily as a thickener and emollient in personal care formulations. This ingredient is valued for its ability to enhance viscosity and create a desirable texture in products, making it suitable for applications in shampoos, body washes, and lotions [2]. Its water-soluble nature allows for easy incorporation into aqueous formulations, contributing to stable and aesthetically pleasing products.

Production Process

The production of PEG-120 Methyl Glucose Sesquistearate typically involves several steps. First, methyl glucose is ethoxylated, reacting it with ethylene oxide to create a polyethylene glycol derivative. This ethoxylated methyl glucose is then esterified with stearic acid, a naturally occurring fatty acid. The esterification process links the stearic acid to the ethoxylated methyl glucose, forming the final PEG-120 Methyl Glucose Sesquistearate molecule [3]. The resulting product is then purified and processed into a usable form, often as flakes or a waxy solid.

Efficacy and Function

PEG-120 Methyl Glucose Sesquistearate primarily functions as a thickener, helping to increase the viscosity of cosmetic formulations [4]. It also acts as an emulsifier, aiding in the stabilization of mixtures containing both water and oil components. Additionally, it provides emollient properties, contributing to the skin's softness and smoothness. Its thickening capabilities improve the texture and application of products, while its emulsifying properties ensure formulation stability, preventing separation of ingredients [5].

Application Scenarios

This ingredient is widely used in various personal care and cosmetic products. It is commonly found in shampoos, where it helps to create a rich, luxurious lather and provides a thicker consistency [6]. In body washes, it enhances viscosity and contributes to a smooth, conditioning feel on the skin. Lotions and creams also benefit from its thickening and emollient properties, improving texture and providing a moisturizing effect. Furthermore, it is used in facial cleansers and other skincare products to improve their overall feel and performance [7].

Packaging and Transportation

PEG-120 Methyl Glucose Sesquistearate is typically packaged in multi-layer paper bags with polyethylene liners or fiber drums to protect it from moisture and contamination. During transportation, it should be stored in a cool, dry environment, away from direct sunlight and extreme temperatures. It should be handled carefully to prevent damage to the packaging, ensuring the product's integrity upon arrival. Standard shipping practices for non-hazardous materials are generally applicable [8].
