First, immediately stop using it, investigate based on the problem manifestation, and obtain professional technical support through the official channels of Guoli Chemical.
Problem Investigation and Common Abnormality Handling
If any abnormality occurs during the use of Castor Oil Ethoxylate EL-80, first make a preliminary judgment based on the phenomenon:
- Poor emulsification or layering: Check whether the HLB value match is appropriate (this product has an HLB value of 16-17, suitable for O/W type emulsification), confirm whether the ratio of oil phase to emulsifier is within the recommended range (usually 2% to 10% of the oil phase mass), and whether the addition sequence is correct — the phase inversion emulsification method should be used, adding this product to the oil phase and then slowly adding water under stirring.
- Poor water solubility, turbid solution: Check whether the storage temperature is too low causing the product to cake or harden (it is recommended to warm up at 20-35°C before use), and confirm whether the water hardness is too high or there is electrolyte interference; this product is stable in hard water, but extreme conditions may still affect the dissolution rate.
- Excessive foaming: This product is a low-foaming surfactant. If abnormal foam occurs, it is mostly due to compatibility conflicts with other high-foaming components in the formulation. It is recommended to test separately and adjust the blending ratio.
- Abnormal product appearance (discoloration, layering, off-odor): Immediately stop use and check whether the storage conditions meet requirements (cool and dry, 5-35°C, container sealed), verify whether the 24-month shelf life has been exceeded or whether the product has been opened and left unsealed for a long time, leading to moisture absorption and deterioration.
How to Obtain Technical Support from Guoli Chemical
Guoli Chemical provides an independent inspection report and a complete Safety Data Sheet (SDS) for each batch of product. Users can obtain professional technical support through the following official channels:
1. Check the accompanying documents: Each shipment is accompanied by a Certificate of Analysis (COA) and a Safety Data Sheet (SDS), which contain the batch number, physical and chemical indicators, and safety operation information. The SDS usually lists the manufacturer's technical consultation phone number and emergency contact information.
2. Contact your dedicated sales manager: Communicate directly with the business contact person at the time of purchase. The sales manager can coordinate technical engineers to provide one-on-one application guidance and formulation optimization suggestions.
3. Call the company's official phone number: Visit the official website of Haian Guoli Chemical Co., Ltd. to obtain the technical department hotline, or look for the printed customer service contact information on the product label or packaging barrel.
4. Provide complete on-site information: When contacting technical support, prepare the following information for quick problem identification: product batch number, use environment temperature and water quality conditions, formulation system and addition ratio, specific description of the abnormal phenomenon, and actual photos.
Precautions
- Be sure to conduct small-scale tests before use to determine the optimal dosage and process conditions, avoiding large-scale investment in unverified formulations.
- If personnel contact injuries occur, refer to the first aid measures in the SDS for initial treatment, then seek medical attention based on the situation and contact the manufacturer to provide toxicological data to assist diagnosis and treatment.
- Product technical parameters should be based on the batch inspection report. Typical data in the database are for reference only. If there are major process adjustment requirements, please request the latest batch technical support.
