Abnormalities during the use of PEG600DO (Polyethylene Glycol 600 Dioleate) usually focus on poor emulsification, emulsion delamination, low-temperature turbidity, or changes in product appearance. Do not panic; most problems can be quickly identified by comparing product characteristics and usage conditions. First, review your formulation process, water quality, and storage environment, as these are often the root causes of issues.
If self-inspection fails to resolve the problem, Haian County Guoli Chemical Co., Ltd. has an experienced application technology team that can provide one-on-one formulation guidance and problem analysis. You can contact our technical engineers directly through the sales channel from which you purchased the product, the company's official website, or the contact information on the product packaging. They will provide targeted optimization suggestions based on your specific application scenario.
The following is a list of frequently encountered issues and possible causes based on the characteristics of PEG600DO for your quick reference:
| Problem Phenomenon | Possible Cause | Suggested Action |
|---|---|---|
| Poor emulsification, unstable emulsion, or delamination | ① HLB value does not match the oil phase (this product has an HLB value of 10-11) ② Insufficient or excessive dosage ③ High water hardness (strong alkali resistance but requires attention to hard water) |
Adjust the emulsifier ratio or use a blend; check the required HLB value of the oil phase in the formulation; first test with deionized water to rule out water quality effects. |
| Product becomes turbid or separates at low temperatures | This product has a pour point below 0°C, and increased viscosity at low temperatures is a normal physical phenomenon. | Allow the product to warm up to 15-30°C before use and stir evenly; the performance can be fully restored. |
| Darkened color or off-odor in the finished product | Storage temperature exceeds 40°C or prolonged exposure to sunlight. | Check storage conditions and strictly control storage in a cool, airtight environment at 5-40°C. |
| Incompatibility with other components in the formulation | This product is non-ionic and is compatible with anionic, cationic, and non-ionic systems, but highly acidic or basic conditions may affect stability. | Confirm the pH and electrolyte concentration of the formulation system. The pH range for this product in a 1% aqueous solution is 5.0-7.0. |
| Skin irritation during handling | This product has mild skin and eye irritation (skin irritation category 2). | Immediately wash with plenty of water and soap. Be sure to wear nitrile rubber gloves and chemical safety goggles during operation. |
When you need professional assistance, you can obtain support from the technical team through the following methods: First, refer to the Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) provided with the shipment, which usually include the company's technical service hotline. Second, contact the distributor or business manager who supplied the product; they can assist in directly connecting you with the factory's technical department. Finally, visit the official website of Haian County Guoli Chemical Co., Ltd., and submit your specific issue via online messaging or the customer service system. Technical engineers will respond as soon as possible during working hours.
This product is not a hazardous chemical, but basic operating guidelines must still be followed: wash hands thoroughly after handling, avoid eye contact, and store away from strong oxidizing agents. In any emergency (e.g., persistent redness, pain, and swelling after eye contact; difficulty breathing after inhaling high concentrations of vapor), seek immediate medical attention and present the product safety data sheet. Technical support provided by the company does not constitute any form of absolute safety guarantee; the safety of the formulation must still be verified through complete testing in the final product by your party.
