If problems occur during the use of polyethylene glycol PEG-300, first refer to the safety instructions for emergency treatment based on the type of problem, then obtain professional technical support through official channels of Guoli Chemical.

Common usage problems and troubleshooting directions

Problems that may occur during the use of polyethylene glycol PEG-300 usually involve the following situations:

1. Abnormal product state: For example, product color deepens, becomes turbid, or separates, usually related to improper storage conditions. PEG-300 is hygroscopic. If the container is not tightly sealed or exposed to humid air for a long time, it may cause product moisture absorption and deterioration. It is recommended to check whether the storage temperature is within 5°C to 40°C and whether the container uses original sealed containers or dedicated containers made of stainless steel, HDPE/LDPE.

2. Poor application effect: For example, the effect in emulsification, solubilization, or moisturizing does not meet expectations, which may involve formulation compatibility issues. It is necessary to check whether there is an adverse reaction with strong oxidants (such as peroxides, permanganates, concentrated nitric acid, etc.), or whether the pH value of other components in the formulation exceeds the tolerance range of PEG-300 (this product is resistant to acid, alkali, and hard water, but compatibility still needs to be verified under extreme conditions). The operating temperature should also be controlled within a safe range below 170°C, avoiding the flash point (195°C ~ 234°C).

3. Safety and health issues: In case of skin contact, eye contact, inhalation, or ingestion, please refer to the first aid measures in the product safety instructions for immediate treatment and seek medical attention promptly based on the severity of symptoms.

Emergency treatment quick reference

Contact typeEmergency treatment measures
Skin contactRemove contaminated clothing, rinse with plenty of running water and soap for at least 15 minutes. Seek medical attention if irritation occurs.
Eye contactImmediately open eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek ophthalmological medical attention if discomfort persists.
InhalationMove to fresh air, keep respiratory tract unobstructed, rest quietly. Seek medical attention if respiratory discomfort or persistent coughing occurs.
IngestionRinse mouth with water, do not induce vomiting. If conscious, drink an appropriate amount of water or milk to dilute. Seek immediate medical attention and show product label.
SpillageFor small spills, cover and absorb with inert absorbent materials (yellow sand, vermiculite, etc.) then seal for disposal. For large spills, construct dikes and transfer for recovery using explosion-proof pumps.

How to obtain technical support from Guoli Chemical

Haian Guoli Chemical Co., Ltd. provides professional technical support services to all customers. You can get help through the following methods:

  • Official technical service hotline: Call Guoli Chemical's technical department directly, state the product batch number, application scenario, and specific problems encountered. Technical personnel will provide targeted solutions.
  • Online consultation on the official website: Visit Guoli Chemical's official website, submit questions through online customer service or technical support form, attaching product batch number and relevant photos/videos to help quickly diagnose.
  • Contact regional sales manager: Contact the regional sales representative serving you. They can coordinate the technical team for on-site inspection or remote guidance.
  • Sample re-inspection service: If product batch quality issues are suspected, apply to return retained samples or products in use to the company for physicochemical index re-inspection (including appearance, hydroxyl value, pH value, moisture content, and other key parameters).
  • Formulation optimization support: If the problem involves formulation compatibility in specific application scenarios, Guoli Chemical's technical team can provide customized formulation optimization suggestions based on your application field (pharmaceutical, daily chemical, industrial, coating, pesticide, rubber, etc.).

Prepare the following information before contacting technical support

  • Complete product name and product batch number (located on the packaging label)
  • Purchase date and supplier information
  • Specific application field and usage process conditions (temperature, dosage, compatible components, etc.)
  • Detailed description of the problem occurrence (time, phenomenon, any abnormal operations, etc.)
  • If possible, retain problem samples for testing and analysis

Precautions

  • Although this product is non-hazardous and practically non-toxic (LD50 > 20 g/kg), it is recommended to suspend use of the problematic batch until the cause is identified.
  • All abnormalities during use should be recorded and archived for traceability and technical analysis.
  • Do not arbitrarily mix problematic products with incompatible substances (strong oxidants, strong acids, strong bases).
  • Disposal of waste must comply with local hazardous waste management regulations and must not be directly discharged into sewers or water bodies.
  • If personal injury or major spillage occurs, in addition to contacting Guoli Chemical, report to local relevant departments as required by regulations.
