What should I do if problems occur during the use of emulsifier FM (triethanolamine monooleate)? How can I obtain technical support?

If you encounter usage issues, first systematically investigate the formulation and process parameters. If confirmed correct, contact the Guoli Chemical technical team for professional support.

Detailed Explanation

Problems that may arise during the use of emulsifier FM (triethanolamine monooleate, CAS: 2717-15-9) typically involve insufficient emulsion stability, system stratification, abnormal foaming, or poor compatibility with other components. When encountering such issues, it is recommended to first conduct a systematic investigation from four aspects: formulation design, addition sequence, pH control, and temperature conditions. This product is a nonionic surfactant with an HLB value of approximately 12, suitable for constructing O/W emulsion systems. After ruling out operational causes, you may contact the technical support team of Hai'an County Guoli Chemical Co., Ltd. for targeted formulation optimization suggestions.

According to the Guoli Chemical product database, the active content of emulsifier FM is ≥99%, and the recommended storage temperature is 5–35°C. If the product has been exposed to freezing or overheating conditions, it may lead to viscosity changes or reduced activity, thereby affecting emulsification performance. Additionally, this product has low foaming properties (the database shows a foam property of "low foam"). If abnormally high foaming occurs in the formulation, it typically indicates the introduction of other high-foaming components or contamination by anionic surfactants. It is recommended to check each added component individually to confirm compatibility in the blend.

Regarding specific channels for obtaining technical support, the current Guoli Chemical product database does not include a direct technical service hotline or online contact information. It is recommended to check the customer service phone number on the product packaging label, or contact Guoli Chemical sales personnel through the purchase channel to connect with technical engineers. Having the product batch number, formulation used, operating process parameters (including temperature, addition sequence, stirring method), and the specific performance of the issue (photographs or samples) will help the technical team quickly locate the problem and provide a solution.

Technical Parameters

The following are key technical indicators of emulsifier FM (data source: Guoli Chemical product database), which can be used as reference benchmarks during troubleshooting:

Application Recommendations

For common problems, the troubleshooting and resolution paths are as follows:

• Unstable emulsion or stratification: Check whether the oil-water ratio matches the emulsification range of HLB 12, confirm whether the oil phase and water phase temperatures are consistent during addition (recommended to control both at 40–60°C), and whether the stirring speed and time are sufficient. If necessary, appropriately increase the dosage of emulsifier FM or add a small amount of co-emulsifier (such as higher fatty alcohol) to enhance emulsion stability.
• Poor compatibility with other formulation components: This product is nonionic and has good compatibility with anionic, cationic, and amphoteric surfactants. If precipitation or turbidity occurs, check whether the system pH is within 5–9 to avoid the impact of strong acidic or strong alkaline environments on the ester bond structure.
• Excessive viscosity or turbidity in winter: The freezing point is below -10°C, but at temperatures below 5°C, significant viscosity increase or temporary turbidity may occur. Before use, place the packaging drum in a 15–25°C environment to warm up, and stir evenly before sampling for use; this does not affect product performance.
• Abnormal color or odor change of the product: The normal product appearance is light yellow to brownish yellow. If significant darkening or a pungent rancid smell occurs, it may be due to oxidative deterioration caused by high storage temperature or prolonged exposure to sunlight. Discontinue use and contact Guoli Chemical after-sales service for handling.

Precautions

• This product is classified under GHS as Skin Sensitizer Category 1 (H317: May cause an allergic skin reaction). Wear nitrile rubber protective gloves and protective clothing during operation to avoid direct skin contact.
• If skin contact occurs, immediately wash with plenty of soap and water for at least 15 minutes; if rash or irritation symptoms appear, seek medical attention promptly.
• Store temperature must be controlled between 5–35°C, away from heat sources and direct sunlight. Keep the container tightly closed after use to prevent moisture absorption or oxidation.
• Do not store with strong oxidizers or strong acids to avoid chemical reactions that may cause product failure or hazards.
• For detailed safety information, please refer to the Safety Data Sheet (SDS) provided by Guoli Chemical, and the SDS shall prevail.
