Product Introduction

Sorbitol ether-20, also known as polyoxyethylene (20) sorbitol ether, is a nonionic surfactant, that is commonly used in cosmetic formulations due to its versatile properties. It is synthesized through the ethoxylation of sorbitol, a sugar alcohol, that is producing a water-soluble ether with a range of applications. This ingredient is valued for its ability to emulsify, solubilize, and modify the viscosity of cosmetic formulations, while enhancing the texture and performance of various personal care products.

Production Process

The production of sorbitol ether-20 typically involves reacting sorbitol with ethylene oxide in the presence of a catalyst. This ethoxylation process adds multiple ethylene oxide units to the sorbitol molecule, and the number "20" in the name indicates the average number of ethylene oxide units attached. The reaction conditions, such as temperature, pressure, and catalyst type, are carefully controlled to achieve the desired degree of ethoxylation and product quality. Following the reaction, the mixture is purified to remove unreacted starting materials and by-products, resulting in a final product of consistent quality and purity.

Efficacy and Function

Sorbitol ether-20 functions primarily as an emulsifier, helping to blend oil and water-based ingredients, creating stable and uniform mixtures in cosmetic formulations [1]. It is an effective solubilizer, ensuring that oils and fragrances are evenly dispersed in water-based products, and acts as a viscosity modifier, enhancing the texture and feel of creams, lotions, and gels. This ingredient can also improve the overall sensory experience of cosmetic products by providing a smooth, non-greasy feel on the skin.

Application Scenarios

Sorbitol ether-20 is widely used in a variety of cosmetic and personal care products, including skin lotions, creams, cleansers, shampoos, conditioners, and makeup [2]. In skin care, it helps to create stable emulsions, improving the delivery of active ingredients, while in hair care, it aids in the even distribution of conditioning agents and fragrances. Moreover, its solubilizing properties make it useful in products containing essential oils or other hydrophobic ingredients, ensuring their even dispersion throughout the formulation.

Packaging and Transportation

Sorbitol ether-20 is generally packaged in plastic drums or containers to maintain its purity and prevent contamination, with containers ranging in size from small bottles to large industrial drums, depending on the quantity required. During transportation, containers should be tightly sealed and protected from extreme temperatures and physical damage, following standard shipping regulations for non-hazardous chemicals, and it is recommended to store the product in a cool, dry place, away from direct sunlight and extreme temperatures, to ensure its stability and shelf life.
