At NINGBO INNO PHARMCHEM CO.,LTD., we recognize N,N-Bis(2-hydroxyethyl)stearamide as a highly versatile nonionic surfactant, a workhorse ingredient with a wide range of industrial applications. Its unique chemical structure and resulting surface-active properties make it invaluable in formulations across cosmetics, detergents, coatings, and more. This article delves into the specific surfactant properties that define its utility.

The defining characteristic of N,N-Bis(2-hydroxyethyl)stearamide is its amphiphilic nature. It consists of a long, hydrophobic stearic acid (C18) chain and two hydrophilic 2-hydroxyethyl groups attached to the nitrogen atom. This dual character allows the molecule to orient itself at interfaces, such as oil-water or air-water, significantly reducing interfacial tension. This fundamental property underpins its effectiveness as an emulsifier, solubilizer, and foam stabilizer.

As an emulsifier, N,N-Bis(2-hydroxyethyl)stearamide excels at forming and stabilizing emulsions. It enables the blending of immiscible liquids, like oil and water, into a homogeneous mixture. This is crucial for products such as lotions and creams, where a stable emulsion ensures a desirable texture and prevents separation. The cosmetic thickener benefits it provides further contribute to the viscosity and overall feel of these products, enhancing user experience.

Its thickening ability is another key attribute. In aqueous systems, it can form supramolecular structures, such as lamellar phases, which increase the viscosity of the formulation. This property is leveraged in detergents and cleaning products to achieve the desired consistency, improving their application and perceived efficacy.

N,N-Bis(2-hydroxyethyl)stearamide also functions as a solubilizer, aiding in the dissolution of less soluble ingredients within a formulation. This is particularly useful for incorporating fragrances, oils, or active ingredients that might otherwise be difficult to disperse uniformly.

The chemical properties of this compound, including its mildness and compatibility with other ingredients, make it a preferred choice for formulators. Its nonionic nature means it is less likely to interact with charged species in a formulation, providing greater formulation flexibility. This versatility extends to its application in coatings and printing inks, where it can act as a wetting and leveling agent to improve the finish and application properties.

NINGBO INNO PHARMCHEM CO.,LTD. is a reliable source for high-quality N,N-Bis(2-hydroxyethyl)stearamide, ensuring that manufacturers have access to a dependable ingredient that consistently delivers on performance.
