Product Introduction

PEG-78 Glyceryl Cocoate is a polyethylene glycol derivative of glyceryl cocoate, a mixture of mono-, di-, and triglycerides of coconut oil ethoxylated with approximately 78 moles of ethylene oxide, according to some sources. It functions primarily as an emulsifier, surfactant, and emollient in cosmetic formulations. The ethoxylation process renders the coconut oil derivative water-soluble, enhancing its ability to blend oil and water phases.

Production Process

The production of PEG-78 Glyceryl Cocoate typically involves the ethoxylation of glyceryl cocoate. Glyceryl cocoate, derived from the reaction of glycerin with coconut fatty acids, undergoes a reaction with ethylene oxide in the presence of a catalyst. The reaction is carefully controlled to achieve the desired degree of ethoxylation, in this case, approximately 78 moles of ethylene oxide per mole of glyceryl cocoate. Following the ethoxylation, the product is purified to remove any unreacted materials and by-products, ensuring a high level of purity and quality for cosmetic applications.

Efficacy and Function

PEG-78 Glyceryl Cocoate provides multiple benefits in cosmetic formulations, acting as an effective emulsifier, helping to blend oil and water-based ingredients to create stable emulsions, preventing separation and ensuring uniform product texture. As a surfactant, it reduces the surface tension of liquids, allowing for better spreading and cleansing properties. The ingredient also functions as an emollient, providing a smoothing and softening effect on the skin.

Application Scenarios

PEG-78 Glyceryl Cocoate is used in a wide array of personal care and cosmetic products. It can be found in cleansers, shampoos, and body washes, where it aids in the removal of dirt and oil while imparting a soft feel to the skin. It is also incorporated into lotions, creams, and other leave-on products, contributing to their texture and moisturizing properties; also suitable for use in baby care products due to its mildness and low potential for irritation.

Packaging and Transportation

PEG-78 Glyceryl Cocoate is typically packaged in drums or IBC (Intermediate Bulk Container) totes to prevent contamination and maintain product integrity. During transportation, containers are secured to prevent movement and potential damage. Storage should be in a cool, dry place away from direct sunlight and extreme temperatures to maintain its stability and quality over its shelf life.
