Toynol® C-17 Cationic Imidazoline Surfactant
Toynol® C-17 Cationic Imidazoline Surfactant
Abstract
Toynol® C-17 is a cationic surfactant based on an alkyl imidazoline structure, designed to address core issues in cathodic electrodeposition coatings and textile auxiliary synthesis, including wetting and dispersion, antistatic performance, and leveling control. Its main functions are to efficiently lower dynamic/static surface tension, promote flow and leveling, and improve pigment dispersion. Compared with conventional solutions, it is APEO-free, highly cost-effective, and has a solids content as high as ≥99%, making it a suitable option for high-performance cathodic electrodeposition coating formulations, amphoteric surfactant synthesis, and antistatic textile treatment.

Main Features and Advantages
- Efficient wetting and dispersion: Markedly lowers the dynamic and static surface tension of waterborne systems, effectively resolving wetting-related cratering and improving pigment dispersion stability.
- Excellent leveling: Promotes coating flow, improves the appearance of electrodeposited films, and reduces defects such as dry spots.
- Environmentally friendly and safe: APEO-free and in line with environmental regulatory trends.
- High cost-effectiveness: High active-ingredient content and low dosage help customers effectively reduce overall costs.
Recommended Application Fields
- Cathodic electrodeposition coatings: As a key additive, resolves dynamic moisture-retention issues of the film during electrodeposition, prevents dry spots, and improves film uniformity and leveling.
- Amphoteric surfactant synthesis: Serves as an important chemical intermediate for synthesizing zwitterionic surfactants with specific properties.
- Textile auxiliaries: As an efficient antistatic and softening component, used in synthetic-fiber spinning, weaving, and other processes to improve fiber processability.
- Industrial cleaners: Provides wetting and dispersion in cleaning formulations requiring cationic characteristics.
Usage and Recommended Dosage
Addition sequence: Add after the other surfactants and polymers to ensure full dissolution or dispersion in the system.
Pre-treatment: If the product solidifies during low-temperature storage, warm it to its melting point (usually room temperature or slightly above) and stir; once it returns to liquid it performs normally.
Recommended dosage:
Uniform mixing: After addition, stir continuously for 15-30 minutes to ensure uniform mixing.
| Application scenario | Calculation basis | Recommended dosage | Remarks |
|---|---|---|---|
| Electrodeposition coating | Total formulation | 0.5% – 2.0% | Run a dose-response study to determine the optimal dosage |
| Other fields | Total formulation | 0.3% – 1.0% | Run a dose-response study to determine the optimal dosage |

Frequently Asked Questions
Q: Is Toynol C-17 an anionic, cationic, or nonionic surfactant?
A: Toynol C-17 is a cationic surfactant. This means it is compatible with cationic or nonionic systems, but caution is needed when used with anionic materials, as a reaction and precipitation may occur; a compatibility test is recommended beforehand.
Q: If the product solidifies at low temperature, has it failed?
A: No. This is a physical property of the product. Simply move it to a warm environment or warm it gently (e.g., in a water bath) until it melts, then stir until homogeneous; it can be used normally with no effect on performance.
Q: What is the main role of Toynol C-17 in electrodeposition coatings?
A: Its main role is to lower the surface tension of the bath, thereby improving film wetting and preventing dry spots caused by overly rapid water evaporation during electrodeposition; it also promotes leveling for a more uniform, level film appearance.
Q: How do I determine the dosage best suited to my process?
A: The optimal dosage depends on your specific formulation and process conditions. We strongly recommend running a dose-response study starting from the lower end of the recommended range (e.g., from 0.5% for electrodeposition coatings) to determine the optimal approach.
