Cetyl Polyethylene Glycol Liquid Non-Ionic Emulsifier EM90 (W/O Type)

Brief Introduction

Cetyl Polyethylene Glycol Emulsifier EM90 is a high-performance liquid non-ionic emulsifier designed for water-in-oil (W/O) systems. It is synthesized by the reaction of cetyl alcohol and ethylene oxide, featuring a unique amphiphilic structure with a hydrophobic cetyl chain and a hydrophilic polyethylene glycol segment.

This emulsifier appears as a clear to pale yellow liquid with good fluidity, and it shows excellent compatibility with most oils, waxes and other non-ionic surfactants. It has stable performance across a wide pH range, and is resistant to electrolytes, making it suitable for formulations containing high levels of salts or active ingredients. What sets it apart is its strong emulsifying ability at low addition levels; it can effectively disperse water phase into oil phase to form stable, fine-grained W/O emulsions, which maintain uniform texture without stratification or creaming during storage. Besides, it is mild to the skin and mucous membranes, meeting the safety standards for personal care products.

Main Applications

Personal Care and Cosmetics IndustryIt is a core ingredient for W/O skincare products, widely used in manufacturing moisturizing creams, nourishing lotions, sunscreen creams and after-sun repair products. The W/O emulsions formulated with EM90 have a light, non-greasy texture that is easy to spread on the skin, and can lock in moisture effectively while delivering oil-soluble active ingredients (such as plant extracts, vitamins and emollients) to the deep layers of the skin. It is also applied in makeup products like foundation creams and concealers, helping to improve the product's adherence to the skin and its long-lasting wear.

Pharmaceutical IndustryIn the pharmaceutical field, it is used as an emulsifier for W/O topical preparations, including ointments, liniments and medicated creams. It can stably disperse water-soluble medicinal ingredients in the oil-based matrix, enhancing the uniformity of the preparation and promoting the absorption of active ingredients through the skin. Its mild properties ensure that it does not cause additional irritation to the skin, making it suitable for medicated products for sensitive skin or damaged skin areas.

Household and Industrial ProductsIt is added to W/O type household care products such as furniture polishes and leather conditioners, helping to form a uniform emulsion system that ensures the even distribution of conditioning components on the surface of objects, leaving a smooth and glossy finish without sticky residues. In the industrial sector, it is used in metal processing fluids and lubricating emulsions, where it helps stabilize the W/O system to improve the lubrication and cooling effects of the fluids, while also enhancing their resistance to high temperatures and mechanical shear.

Agricultural ChemicalsIn pesticide formulations, it serves as an emulsifier for W/O type pesticide emulsions. It can disperse water-based additives into the oil phase of pesticides, improving the stability of the pesticide formulation and enhancing its adhesion and spreading ability on crop surfaces. This helps to reduce the loss of pesticides due to water washing and improve the efficacy of pest and disease control.
