1303 Isotridecyl Alcohol Polyoxyethylene Ether is a nonionic surfactant belonging to the isotridecanol ethoxylate family. It is produced by the ethoxylation of isotridecyl alcohol, a branched C13 alcohol, with ethylene oxide. The product carries the CAS registry number 69011-36-5 and the EINECS number 500-241-6. Its molecular formula is C₁₃H₂₇O(CH₂CH₂O)ₙOH, where n represents the average number of ethylene oxide units. The 1303 grade corresponds to a specific ethoxylation level that yields a cloud point in the range of 49.0°C to 52.0°C.

As a nonionic surfactant, 1303 functions through the hydrophilic polyethylene oxide chain and the hydrophobic branched tridecyl tail. This structure provides surface-active properties including emulsification, wetting, and dispersion capabilities. The product remains stable in both acidic and alkaline environments, which allows its use across a range of formulation pH conditions.
The cloud point of 49.0°C to 52.0°C indicates the temperature range at which the surfactant begins to phase-separate from aqueous solution. Below this temperature, the product is fully water-soluble and exhibits maximum surface activity. This cloud point range makes the 1303 grade suitable for applications operated at or near ambient temperatures, where solubility and surfactant activity are both required.
The product shows solubility in water and various organic solvents. Its low surface tension contributes to improved wetting of solid surfaces and enhanced penetration of formulations into porous substrates. These properties are relevant in industrial cleaning, agrochemical adjuvant systems, and textile processing applications.
1303 isotridecyl alcohol ethoxylate is used in the formulation of industrial cleaners for equipment surfaces, hard surfaces, and metal parts. Its wetting and emulsifying properties support the removal of oils, greases, and particulate soils from various substrates. The surfactant can be incorporated into both alkaline and neutral cleaning systems, where it contributes to soil lifting and suspension. Formulations may include it alongside builders, chelating agents, and other surfactants to achieve targeted cleaning performance.
In agricultural formulations, 1303 serves as a nonionic adjuvant for pesticide and herbicide sprays. It improves the wetting and spreading of spray droplets on leaf surfaces, which can enhance the uniformity of coverage and the uptake of active ingredients. The surfactant's compatibility with a range of pesticide chemistries makes it a candidate for inclusion in adjuvant packages designed to improve spray deposition and retention on target plants.
The 1303 grade finds application in textile processing as a wetting agent and emulsifier. In pre-treatment processes such as scouring and bleaching, it aids in the wetting of fiber bundles and the removal of natural waxes and impurities. It can also be used as an emulsifier for silicone softeners and other textile auxiliaries, helping to maintain stable emulsions during padding and exhaustion processes.
1303 isotridecyl ethoxylate may be incorporated into personal care and cosmetic products as an emulsifier, solubilizer, or cleansing agent. Its moisturizing and lubricating characteristics support its use in creams, lotions, and hair care formulations. In shampoo and body wash products, it can contribute to foam quality and mildness when properly formulated.
1303 isotridecyl alcohol polyoxyethylene ether is available in industrial packaging including iron drums, IBC totes, and ISO tank containers. The minimum order quantity is 1 metric ton. The product should be stored in a cool, dry location with containers sealed to prevent moisture ingress. Material Safety Data Sheet (MSDS) and Certificate of Analysis (COA) are available upon request.
The 1303 designation refers to a specific grade of isotridecyl alcohol ethoxylate with a defined cloud point range of 49.0°C to 52.0°C. The numbering system indicates the ethoxylation level, with higher numbers generally corresponding to higher ethylene oxide content and higher cloud points.
Yes, as a nonionic surfactant, 1303 is generally compatible with anionic, cationic, and amphoteric surfactants. It is commonly used in combination with other surfactant types to achieve targeted formulation properties such as foam profile, detergency, and emulsification performance.
The product should be stored at temperatures between 10°C and 40°C. At temperatures below its cloud point, the product remains fully soluble in its own aqueous phase. Prolonged storage at elevated temperatures should be avoided to maintain product quality.
The 1303 grade has a cloud point of 49.0°C to 52.0°C, meaning it loses water solubility above this temperature range. For processes operating at higher temperatures, a higher ethoxylate grade such as 1309 (cloud point 55.0°C to 59.0°C) may be more appropriate.
