Refined Coconut Oil 6501-98% (Ninol), a high-purity nonionic surfactant (Cocamide DEA), may occasionally experience issues such as unsatisfactory thickening, unstable foam, poor transparency, or stratification during use. In most cases, the problem is not due to product quality but rather related to the formulation system, addition process, water quality conditions, or incompatibility with other raw materials. It is recommended to troubleshoot step by step before determining whether the product is abnormal.
Guoli Chemical provides comprehensive after-sales technical support services for every customer. If the problem persists after troubleshooting, you can contact the salesperson through the product procurement channel to arrange one-on-one remote diagnosis with a technical engineer. Alternatively, you can directly call the customer service hotline published on Guoli Chemical's official website or send an email to the technical support mailbox, providing the product batch number, formulation system, and a description of the phenomenon. The technical team typically responds within 1-2 working days. For major or urgent issues, on-site technical service can also be requested.
Possible Causes: 6501 is a nonionic auxiliary thickener that needs to be used in combination with anionic surfactants (such as AES, LAS, etc.) and electrolytes (sodium chloride) to achieve optimal thickening. Using it alone or in insufficient amounts will not effectively thicken the system. Additionally, a system pH value too high (>10) or temperature too high can weaken the thickening ability.
Troubleshooting Suggestions: Confirm whether the formulation contains sufficient anionic primary surfactant; check if the sodium chloride addition amount is within the reasonable range (typically 0.5%-2.0% of the system); verify the addition amount of 6501 (recommended 0.5%-5.0%); ensure the addition temperature is below 40°C to avoid high-temperature degradation.
Possible Causes: 6501 mainly acts as a foam stabilizer and synergist, not as a primary foaming agent. If the formulation lacks high-foaming anionic surfactants (such as AES, K12), relying solely on 6501 will not produce abundant foam. Excessive amounts of oils or silicones in the formulation can also defoam.
Troubleshooting Suggestions: Check the type and amount of primary foaming agent in the formulation; appropriately increase the addition ratio of 6501 (1%-3%); confirm whether any defoaming components have been introduced; check if the water hardness is too high.
Possible Causes: 6501 may solidify or become cloudy at low temperatures (below 10°C), which is a normal physical phenomenon. Additionally, incompatibility may occur when used with certain cationic surfactants or acidic substances. A pH value below 5 may cause hydrolysis of 6501.
Troubleshooting Suggestions: Allow the product to warm up to 20-35°C and stir evenly to observe; check if the system pH is below 5 or above 10; verify the compatibility of the ionic types of co-ingredients with 6501.
Possible Causes: According to GHS classification, 6501 (H315\/H319) can cause skin and eye irritation. Excessive addition of 6501 in the formulation, high residual free amine, or synergistic amplification of overall formulation irritation may lead to discomfort.
Troubleshooting Suggestions: Check if the addition amount of 6501 exceeds the recommended range (typically 1%-4% for personal care products); confirm the overall irritation assessment of the formulation; reduce the dosage if necessary or choose a product specification with lower free amine content.
