Isotridecyl alcohol polyoxyethylene ether is a non-ionic surfactant belonging to the ethoxylated alcohol family. Designated as IS1310, this grade contains an average of approximately 10 moles of ethylene oxide per mole of isotridecyl alcohol, placing it in the mid-to-high EO range of the product family. The CAS number 69011-36-5 is the general registration number for the isotridecyl alcohol ethoxylate category, covering products with various EO degrees from approximately 3 to 20.
The molecular structure of IS1310 follows the formula C₁₃H₂₇O(CH₂CH₂O)ₙH, with n approximating 10. The branched C13 hydrophobic tail combined with the polyethylene oxide hydrophilic chain produces an HLB value of approximately 13.5-14.5. This HLB range positions IS1310 as an effective detergent and emulsifier for oil-in-water systems, with greater water solubility than lower EO grades such as IS1308.
The ethoxylation degree of IS1310 corresponds to a cloud point of 73.0-77.0°C (measured in 1% aqueous solution), which is significantly higher than the 47.0-50.0°C cloud point of the 8-mole EO grade. This higher cloud point means IS1310 remains water-soluble and fully functional at elevated temperatures, making it suitable for high-temperature cleaning and processing applications that would cause lower EO grades to phase separate.
The branched structure of the isotridecyl group provides several functional benefits compared to linear alcohol ethoxylates, including faster wetting speed, better penetrating power, and improved low-temperature handling properties. The non-ionic nature of the surfactant ensures stable performance across a wide pH spectrum and compatibility with various other surfactant types and formulation additives.
The following table outlines the technical parameters of IS1310, determined through standardized quality control procedures.

Water content is determined by Karl Fischer titration (ISO 760), ensuring that moisture levels remain below 0.2% to maintain product stability and consistency. The pH value of a 1% solution in demineralized water falls within the slightly acidic to neutral range of 5.0-7.0, measured using a calibrated pH electrode according to standard procedures.
Cloud point determination follows ISO 1065 methodology. The 73.0-77.0°C cloud point range of IS1310 is a critical specification that defines its upper temperature limit for aqueous applications. Color measurement on the APHA (Hazen) scale (ISO 2211) yields values of 30 and below, indicating a product with low color and minimal oxidative degradation. Visual inspection at 25°C confirms the product appears as a white cloudy liquid free of mechanical impurities. Each production batch undergoes full quality verification, and COA documents are available for commercial procurement upon request.
IS1310 exhibits strong detergency properties derived from its balanced HLB and branched alkyl structure. The surfactant effectively reduces surface tension and penetrates soil layers, facilitating the removal of oils, greases, and particulate soils from various substrates. Its 10-mole EO content provides a favorable balance between oil-dissolving capacity and water solubility, making it effective for a wide range of cleaning tasks.
In terms of wetting performance, IS1310 demonstrates rapid wetting action on both hydrophilic and hydrophobic surfaces. This attribute is particularly valuable in spray cleaning operations where the cleaning solution must quickly spread across the target surface to maximize contact time with soil. The surfactant also contributes to foam generation, though its foam profile can be adjusted through formulation with other surfactants or foam control agents.
IS1310 maintains stability across a broad pH range, from approximately pH 2 to pH 12, making it suitable for both acidic and alkaline cleaning formulations. This acid and alkali resistance allows the surfactant to be used in diverse cleaning products, from acidic descalers and rust removers to strongly alkaline degreasers and caustic cleaners. The ether bonds in the polyethylene oxide chain are resistant to hydrolysis under both acidic and alkaline conditions at normal use temperatures.
The surfactant is compatible with a wide range of formulation ingredients commonly used in industrial cleaning products, including builders (sodium hydroxide, sodium carbonate, phosphates), chelating agents (EDTA, NTA, citrates), hydrotropes, and corrosion inhibitors. It can be blended with anionic surfactants such as linear alkylbenzene sulfonates (LAS) and alcohol ether sulfates (AES) to create synergistic cleaning systems with enhanced soil removal capabilities.
The high cloud point of IS1310 (73.0-77.0°C) makes it particularly well-suited for high-temperature industrial cleaning operations. Applications include hot spray cleaning of metal parts, machine parts degreasing at elevated temperatures, and CIP (Clean-in-Place) systems in food and beverage processing plants. Unlike lower EO grades that lose solubility and effectiveness above their cloud point, IS1310 remains fully functional at temperatures commonly used in industrial cleaning processes.
For business operations in the metal fabrication and automotive sectors, IS1310 is incorporated into alkaline degreasing formulations operated at 50-70°C. At these temperatures, the surfactant provides effective removal of machining oils, cutting fluids, and protective greases from steel, aluminum, and other metal surfaces. The typical use concentration in these applications ranges from 1% to 3% by weight in the working solution.
In textile processing, IS1310 finds application in high-temperature scouring, bleaching, and dyeing processes. Its stability at elevated temperatures allows it to function effectively in continuous scouring ranges and jet dyeing machines where operating temperatures can reach 70°C and above. As a wetting and scouring agent, it assists in the removal of natural impurities, spinning oils, and sizing agents from cotton, polyester, and blended fabrics.
In dyeing applications, IS1310 can serve as a leveling agent and dispersant, helping to achieve uniform dye distribution and prevent agglomeration of dye particles. Its non-ionic nature makes it compatible with most dye classes, including reactive, direct, and disperse dyes. For enterprise customers in the textile finishing sector, IS1310 also contributes to the penetration of finishing chemicals and softeners into fiber bundles.
IS1310 is a common ingredient in household and institutional (HI&I) cleaning products, including all-purpose cleaners, laundry detergents, and dishwashing liquids. Its balanced detergency, combined with good foaming properties and compatibility with other surfactants, makes it a versatile component in formulated cleaning products. In laundry applications, it contributes to the removal of oily and greasy soils from fabrics.
For commercial users in the cleaning product manufacturing sector, IS1310 can be used as a primary non-ionic surfactant or as a co-surfactant in combination with anionic surfactants. The typical incorporation rate in finished products ranges from 2% to 15%, depending on the product type and performance requirements. Its stability across pH ranges allows formulation in both neutral and alkaline cleaning products.
IS1310 is supplied in standard industrial packaging options to meet different volume requirements. The product is available in 200-liter steel drums with an approximate net weight of 200 kg per drum, 1000-liter IBC totes with an approximate net weight of 1000 kg, and ISO tank containers for bulk quantities. The minimum order quantity is 1 ton.
Storage recommendations include keeping the product in tightly sealed containers in a cool, dry warehouse environment, away from direct sunlight and ignition sources. The product should be protected from extreme temperatures, both high and low, to maintain quality. Under proper storage conditions, the shelf life is approximately 24 months from the manufacturing date. Safety data sheets (SDS) provide detailed information on handling, storage, personal protection, and emergency response procedures.
The primary difference is the cloud point: IS1310 has a cloud point of 73.0-77.0°C compared to 47.0-50.0°C for IS1308. This means IS1310 remains fully water-soluble and effective at higher temperatures, making it the preferred choice for hot cleaning processes, high-temperature textile processing, and any application where the operating temperature exceeds 45-50°C. IS1308 is more suitable for ambient temperature applications and may offer better low-foam characteristics at elevated temperatures above its cloud point.
Yes, IS1310 exhibits stability across a wide pH range, from approximately pH 2 to pH 12. This allows it to be incorporated into acidic cleaners such as descalers and rust removers, as well as strongly alkaline degreasers and caustic cleaning solutions. The non-ionic nature of the surfactant means its performance is not significantly affected by pH changes within this range.
In ready-to-use cleaning solutions, typical concentrations range from 0.5% to 3% by weight. For concentrated products that are diluted before use, IS1310 can be incorporated at levels of 5% to 20% of the concentrate. The exact dosage depends on factors such as the type and amount of soil, cleaning method (spray, immersion, ultrasonic), temperature, water hardness, and the presence of other formulation components like builders and chelating agents.
