Product Introduction

PEG-7 Hydrogenated Castor Oil functions primarily as an emulsifier and surfactant in cosmetic formulations, helping to blend oil and water-based ingredients. It is derived from castor oil through a process of hydrogenation and ethoxylation. This ingredient enhances the stability and texture of various personal care products.

Production Process

The production of PEG-7 Hydrogenated Castor Oil begins with the hydrogenation of castor oil, a process that saturates the fatty acid chains, making them more stable. Following hydrogenation, the oil undergoes ethoxylation, where ethylene oxide units are added. The "7" in the name signifies that on average, seven units of ethylene oxide are incorporated into the molecule. The ethoxylation process increases the ingredient’s water solubility and emulsifying properties.

Efficacy and Function

PEG-7 Hydrogenated Castor Oil acts as an effective emulsifier, enabling the formulation of stable mixtures of oil and water [1]. As a surfactant, it reduces surface tension, allowing for better dispersion of ingredients and enhanced cleansing action [2]. Its emollient properties also contribute to skin softening in cosmetic products.

Application Scenarios

In skincare, PEG-7 Hydrogenated Castor Oil is used in cleansers, creams, and lotions to improve texture and facilitate the mixing of ingredients [3]. It is also utilized in hair care products like shampoos and conditioners for its emulsifying and conditioning benefits [4]. Additionally, it can be found in makeup formulations, ensuring even distribution of pigments and oils.

Packaging and Transportation

PEG-7 Hydrogenated Castor Oil is typically packaged in plastic drums or containers to prevent contamination and ensure easy handling. Transportation should adhere to standard practices for non-hazardous materials, keeping the containers sealed and protected from extreme temperatures. Proper labeling with safety and handling instructions is essential.
