How to use Isomeric Tridecanol Polyether E-1306? The usage method should be determined based on the specific application scenario. It is generally recommended to add the product directly to water under stirring, or dilute it in warm water below the cloud point (about 44~46°C) for optimal performance.
Detailed Description
Isomeric Tridecanol Polyether E-1306 is a high-activity nonionic surfactant (active content ≥99%) with good water dispersibility and low-temperature fluidity. In practical applications, the operation method mainly depends on its specific formulation role. When used as a penetrant, wetting agent, or cleaning component, it is typically directly added to water with stirring for dilution; when used as an emulsifier to prepare an emulsion system, it should first be mixed uniformly with the oil phase, and then slowly add water under high shear to form a stable emulsion.
This product has a cloud point of 44~46°C (1% aqueous solution). Above this temperature, the product will precipitate from water and become turbid due to dehydration. Therefore, if you need to prepare a transparent aqueous solution, it is recommended to control the water temperature below 40°C. When used in low-temperature environments, its unique isomeric branched chain structure gives the product excellent low-temperature fluidity, making it less prone to solidification, and no additional heating is required for winter operation. It exhibits stable performance in hard water and a wide pH range, and can be compounded with other types of surfactants such as anionics and cationics to synergistically enhance performance.
Technical Parameters
The following are key physicochemical parameters that affect the usage method and performance of E-1306 (data source: Guoli Chemical Product Database):
| Parameter Item | Typical Value | Reference Significance for Use |
|---|
| HLB Value | 11.5 | Moderate hydrophilic-lipophilic balance, suitable as O/W emulsifier and wetting penetrant |
| Cloud Point (1% Aqueous Solution) | 44~46 °C | Dilution water temperature should not exceed this temperature for a long time to ensure transparency and activity |
| Critical Micelle Concentration (CMC) | 10~20 mg/L | Extremely low CMC means low dosage can significantly reduce surface tension |
| Surface Tension (0.1%, 25℃) | Approx. 28.5 mN/m | Small addition can achieve excellent wetting and spreading effect |
| Pour Point | < 0℃ | Remains liquid at low temperatures, no preheating required for winter use, convenient operation |
| Foam Characteristics | Low Foam | Suitable for industrial scenarios requiring fast foam collapse such as high-pressure spray cleaning |
Application Recommendations
Based on the technical characteristics of E-1306 and common industry practices, specific usage methods and recommended addition amounts in different fields are as follows (the optimal dosage should be verified through experiments):
- Industrial and Institutional Cleaning: Used as the core degreasing component in metal cleaners and hard surface cleaners. Recommended addition amount is 2~8% of the total formulation. Add directly to water with stirring to dissolve, and combine with alkaline additives to enhance degreasing efficiency. Its low-foam property is especially suitable for high-pressure spray and circulation cleaning processes.
- Textile Printing and Dyeing Auxiliaries: When used as an efficient penetrant and scouring agent, the recommended dosage in the pretreatment bath is 0.5~3 g/L. It can significantly improve the fabric wetting speed and capillary effect, helping to remove wax and pectin from cotton fibers.
- Metalworking Fluids: When preparing emulsified or semi-synthetic cutting fluids, as part of the anionic-nonionic emulsifier composite system, the recommended addition amount is 3~5% of the working fluid weight. First dissolve in the base oil, then add water for emulsification, providing anti-rust, lubrication, and cleaning multiple effects.
- Pesticide Emulsifiers: When preparing emulsion concentrates (EW) or microemulsions (ME), use as a co-emulsifier. Usually compounded with anionic emulsifiers (such as calcium salts), with an addition ratio of about 2~10% of the total formulation. First dissolve the active ingredient in this product, then add water for co-emulsification, which can significantly improve the wetting and spreading of the spray liquid on leaves.
- Leather Processing: In the soaking and degreasing processes, add through a drum, with a reference dosage of 0.3~0.8% of the pelt weight. It can accelerate the penetration of water and chemicals into the core of the skin, shorten soaking time, and emulsify and remove natural fats from raw hides.
Precautions
Strict safety precautions must be observed when handling this product:
- Eye Protection: This product is classified as a severe eye irritant (H319 warning). During charging and dilution, be sure to wear chemical safety goggles to prevent liquid splashing into eyes. If accidentally gets into eyes, rinse continuously with clean water for at least 15 minutes and seek medical attention.
- Storage and Shelf Life: It is recommended to store in a dry and well-ventilated environment at 5°C to 40°C. Tightly close the container lid after use. Under the principle of first-in-first-out management, unopened products have a long shelf life; use opened products as soon as possible.
- Compounding Prohibitions: The product is chemically stable, but before mixing or storing with incompatible substances such as strong oxidizers, strong acids, or strong bases, small-scale compatibility tests must be conducted.
- Personal Hygiene: Wash hands thoroughly after handling. Eating, drinking, or smoking is prohibited during work.
