Lutensol AT 25 Powder belongs to the class of alcohol ethoxylates (AE) developed for excellent solubilizing and detergency performance, particularly in low-foam, high-efficiency cleaning systems.
Its powder form offers enhanced stability, easier handling, lower spillage risk, and reduced volatility compared to liquid surfactants, making it suitable for detergent powders, tablets, and solid industrial cleaners.
The molecular structure produces a high hydrophilic-lipophilic balance (HLB) value, enabling powerful oil emulsification and soil dispersion, even in cold or low-alkaline water environments.

Lutensol AT 25 Powder exhibits broad compatibility with different surfactant classes and additives, allowing it to function as a universal nonionic surfactant in multi-component formulations used across home care, industrial maintenance, polymer chemistry, and agrochemical products.
Lutensol AT 25 Powder is a nonionic surfactant belonging to the group of ethoxylated fatty alcohols, designed to lower surface tension and improve wetting, emulsification, and solubilization in various formulations.

Lutensol AT 25 Powder is typically based on C₁₂–C₁₄ fatty alcohols reacted with approximately 25 moles of ethylene oxide, giving it strong hydrophilic characteristics.
Provided in powder form for easy handling and incorporation into detergent, cleaning, and industrial formulations.
Exhibits excellent compatibility with anionic, cationic, and amphoteric surfactants, enabling use in complex cleaning systems.

Highly effective in cold-water detergency and low-foaming systems, making it suitable for both consumer and industrial cleaning applications.
Has strong solubilizing and emulsifying power for oils, waxes, and hydrophobic substances in aqueous environments.
Lutensol AT 25 Powder is a polyoxyethylene fatty alcohol surfactant classified within high-ethoxylate nonionic surfactants, developed to provide controlled interfacial tension reduction, wetting kinetics, and soil detergency performance across a wide range of pH and electrolyte conditions.

Its long-chain alkyl backbone (C₁₂–C₁₄) supplies efficient hydrophobic anchoring to oily surfaces, while the extended polyether chain enhances solubility, improving detergent action by increasing micelle solubilization capacity.
The ~25 EO units confer a high HLB (Hydrophilic–Lipophilic Balance), positioning it specifically for oil-in-water emulsion stabilization, dispersing poorly soluble compounds and maintaining homogeneous systems during processing.

Lutensol AT 25 Powder is a member of the ethoxylated fatty alcohol surfactant family engineered to provide high detergency, dispersion, and wetting efficiency through its amphiphilic architecture, where a lipophilic alkyl tail interacts with soils while the hydrophilic polyether chain ensures solubility in water.
Due to the high ethoxylation degree (~25 EO units), the molecule has a high cloud point and remains stable in alkaline, high-electrolyte, and oxidative cleaning environments, making it compatible with harsh industrial processing conditions.

Its nonionic nature allows it to be unaffected by water hardness (Ca²⁺/Mg²⁺), unlike anionic surfactants, ensuring consistent performance in hard water and metal-rich systems.
Lutensol AT 25 Powder disperses hydrophobic materials through micelle formation, encapsulating oils/greases and suspending dirt particles to prevent redeposition during washing and processing.
It is valued for low foaming properties, especially important in machine cleaning, CIP (clean-in-place) systems, textile jet machines, and industrial washers where excessive foam disrupts mechanical washing efficiency.

Because of its molecular structure and solid form, it acts both as a primary surfactant and a processing aid, improving powder flow, granulation stability, and product shelf life in solid formulations.
Lutensol AT 25 Powder is engineered through a controlled ethoxylation reaction, where ethylene oxide molecules are added stepwise to a fatty alcohol backbone, resulting in a sophisticated polyoxyethylene chain distribution that determines its surfactant performance profile (solubility, HLB, cloud point).

Its physicochemical behavior is governed by intermolecular hydrogen bonding between polyether chains, creating a balance between hydrophilicity and steric stabilization, which is especially important in high-electrolyte environments where many surfactants lose performance.
The surfactant operates via micellar and interfacial adsorption mechanisms, forming organized nanoscale structures that lower interfacial energy, allowing rapid soil release and wetting even on hydrophobic polymer surfaces and oily particulate matter.
Owing to its solid-state morphology, Lutensol AT 25 Powder demonstrates enhanced thermal stability and transportability, reducing the need for solvents, improving ecological metrics (biodegradable and APEO-free), and enabling direct use in powdered delivery systems without phase separation risks.

At the microscopic interface, it can enhance detergency synergistically with builders (e.g., sodium carbonate), enzymes, and hydrotropes by facilitating substrate accessibility — this synergy underpins its high value in professional cleaning and high-efficiency detergent technology.
The high ethoxylation level makes it suitable for use in foam-sensitive operations, where extreme agitation, jet washing, or recirculation would otherwise cause excessive foam levels and mechanical operational issues.

Lutensol AT 25 Powder is an oil-in-water emulsifier that is used for the production of ointments, creams, liquid emulsions, gels and other cosmetic formulations. 
It is supplied in the form of free-flowing, non-dusting micro-granules, and is an efficient protective colloid that can increase the stability of dispersed systems. 
This research grade product is intended for use in R&D only.

Due to its structural design, Lutensol AT 25 exhibits exceptionally low critical micelle concentration (CMC), meaning low usage levels achieve effective detergency and wetting — ideal for concentrated formulations and ecological optimization.
It demonstrates thermal and oxidative stability, with resistance to hydrolysis in alkaline and oxidizing detergent conditions, making it suitable for industrial cleaning and high-performance detergent systems.
The granular or powder physical form minimizes the handling challenges associated with viscous liquids, enabling optimized storage stability, dosing accuracy, and blending in solid cleaning products, including automatic dishwashing tablets, laundry powders, and industrial cleaning blocks.
