Tridecyl Alcohol Ethoxylate

Tridecyl Alcohol Ethoxylates are biodegradable nonionic surfactants formed by the reaction of ethylene oxide with tridecyl alcohol (C13 alcohol). The ethoxylation process attaches hydrophilic polyoxyethylene chains to the hydrophobic tridecyl alcohol backbone, producing molecules that are amphiphilic in nature. This dual affinity allows them to reduce surface tension, stabilize emulsions, and solubilize oils and other hydrophobic compounds in water-based systems. Their biodegradability and nonionic nature make them environmentally friendly and compatible with a wide range of formulation ingredients, making them highly suitable for industrial, personal care, and agricultural applications.

C13 alcohol ethoxylates, also referred to as tridecyl alcohol ethoxylates, can vary in physical form depending on the degree of ethoxylation. Lower ethoxylation grades are often clear or slightly hazy liquids, while higher ethoxylation levels can result in white solid products. Increasing the number of ethylene oxide units enhances water solubility, reflected in a higher hydrophilic–lipophilic balance (HLB) value. Other physical properties, including pour point, cloud point, density, viscosity, and flash point, also change with ethoxylation, allowing formulators to select grades tailored to specific functional requirements in diverse applications.

Tridecyl alcohol ethoxylates are widely used across industries. In personal care and cosmetics, they serve as emulsifiers, solubilizers, and surfactants in creams, lotions, shampoos, and other rinse-off or leave-on products. They facilitate the uniform distribution of oils and fragrances, improve product texture, and contribute to mild cleansing action. In industrial and agricultural applications, these ethoxylates can be incorporated into ether sulfates, ether carboxylates, emulsifiable concentrates, and dispersing agents. Their ability to stabilize formulations and enhance wetting or spreading properties makes them invaluable in chemical, textile, and crop protection formulations.

We manufacture tridecyl alcohol ethoxylates according to customer specifications, providing tailored products with varying levels of ethoxylation to suit specific application needs. These products are known by several synonyms, including Polyoxyethylene Tridecyl Alcohol, Polyethylene Glycol Tridecyl Ether, Polyoxyethylene Iso Tridecyl Alcohol, and alpha-Tridecyl-omega-hydroxy-poly(oxy-1,2-ethanediyl). This flexibility in formulation, combined with their excellent surfactant properties and environmental compatibility, makes tridecyl alcohol ethoxylates a reliable choice for manufacturers seeking high-performance nonionic surfactants.
