Question 2

What should I do if problems occur during the use of Octadecylamine Polyoxyethylene Ether AC-1815? How to obtain technical support?

Accepted Answer

If problems occur while using AC-1815, first handle personnel safety according to emergency procedures, then troubleshoot process parameters, and finally contact the Guoli Chemical technical team for professional support. Detailed Explanation When problems occur during the use of Octadecylamine Polyoxyethylene Ether AC-1815, you first need to determine the nature of the problem. If it is discomfort caused by personnel contact, immediately follow the emergency response measures in the product safety instructions. If it is a process application issue (such as emulsion instability, poor leveling effect, precipitation, etc.), you need to investigate step by step from aspects such as formulation conditions, process parameters, and storage status. As a special surctant with both nonionic and cationic characteristics (CAS: 26635-75-6), the performance of AC-1815 is closely related to the system pH, temperature, water hardness, and compatible raw materials. For example, under acidic conditions, it exhibits cationic characteristics, which differ from its emulsifying and leveling behavior in the nonionic state. If the application temperature exceeds its cloud point (≥90°C, 1% aqueous solution), it may also lead to functional decline. Therefore, it is recommended to record specific process conditions during troubleshooting so that technical personnel can quickly identify the issue. Regarding channels for obtaining technical support, there is currently no publicly available customer service phone number or online contact method in the Guoli Chemical product database. It is recommended to directly contact the Guoli Chemical sales manager or distributor from whom you purchased the product. They can typically provide product application technical consultation, formulation adjustment suggestions, and sample re-inspection services.

Question 5

What are the advantages of octadecylamine polyoxyethylene ether AC-1815 compared to other similar products?

Accepted Answer

AC-1815 achieves a "golden balance" of hydrophilic and lipophilic performance within the octadecylamine polyoxyethylene ether series, combining excellent emulsifying, dispersing, leveling, and migrating properties with antistatic capabilities, while also featuring low foam characteristics and broad chemical compatibility. It is the most cost-effective multifunctional auxiliary in fields such as textile printing and dyeing, and metalworking. Detailed Explanation Octadecylamine polyoxyethylene ether AC-1815 (EO number = 15) is a classic grade in the Guoli Chemical AC series. Compared to other products in the same series, such as AC-1810 (EO=10), AC-1812 (EO=12), AC-1820 (EO=20), and AC-1830 (EO=30), the ethylene oxide addition number of AC-1815 is precisely at the critical region where hydrophilicity and lipophilicity are balanced. Products with lower EO numbers, like AC-1810\/1812, are too lipophilic, limiting water solubility and dispersion speed. Products with higher EO numbers, like AC-1820\/1830, have excellent water solubility but reduced emulsification and penetration capabilities for oils and waxes. AC-1815 achieves the optimal balance in this contradiction, quickly dissolving in water to form a stable emulsion while maintaining strong adsorption and emulsification on various hydrophobic substrates. Compared to other similar products, AC-1815 exhibits a unique "low foam, high-efficiency wetting" characteristic. Most nonionic surctants introduce a large amount of foam while enhancing emulsifying power, causing issues in processes like high-speed stirring and high-pressure spraying. However, due to its moderate polyoxyethylene chain length, AC-1815 generates significantly less foam than more hydrophilic grades like AC-1820\/1830, while ensuring excellent wetting and spreading properties, making it more suitable for processing systems sensitive to foam. Additionally, AC-1815's triple chemical tolerance (acid resistance, alkali resistance, and hard water resistance) is particularly outstanding in practical applications. It maintains high activity even in high-temperature acidic dye baths or high-hardness water environments without precipitation or decomposition, a stability level that is leading among similar products. In terms of ionic property conversion, the amine activity of AC-1815 is precisely preserved due to the moderate shielding effect of its EO chain. It can convert to a cationic form under acidic conditions, imparting excellent adsorption and soft conditioning effects to substrates. This is unmatched by products with excessively high EO numbers (e.g., AC-1860), as overly long polyoxyethylene chains severely weaken the amine's cationization ability and adsorption strength on negatively charged surces. Therefore, in application scenarios requiring both nonionic emulsification and cationic conditioning (e.g., textile leveling agents, metal antirust fluids, shampoo and hair care products), AC-1815's comprehensive performance r exceeds that of other grades in the same series. Technical Parameters The following is a key performance comparison between AC-1815 and other main products in the series (some parameters are derived from typical values and are for reference only): Product ModelEO Addition NumberAppearanceHydrophilic-Lipophilic Balance TendencyWater SolubilityFoaming CharacteristicsLeveling and Migration AbilityCationization Activity AC-181010Light yellow to yellow waxy solidLipophilicDispersible\/MilkyLow foamMediumStrong AC-181212Light yellow to yellowLipophilicDispersibleLow foamGoodRelatively strong AC-181515Light yellow waxy\/pasteHydrophilic-lipophilic balanceEasily soluble\/Clear to slightly turbidLow foamExcellentModerately strong AC-182020Light yellow to yellowHydrophilicEasily soluble\/ClearMedium foamingGoodRelatively weak AC-183030Light yellow to yellowStrongly hydrophilicVery easily soluble\/ClearMore foamingAverageWeak AC-186060Light yellow to yellowish-brown solidExtremely hydrophilicVery easily soluble\/ClearSignificant foamingWeakVery weak (The above performance data is a comprehensive evaluation based on product database information and general patterns. For specific parameters, please refer to Guoli Chemical's actual test reports.) Application Recommendations Textile Printing and Dyeing - First choice for leveling agents: If the core requirement of the formulation is to improve dyeing uniformity and reduce color differences and defects, AC-1815's migration and retardation ability is the best in the series, making it the preferred option. High temperature\/Strong acid-base environments: AC-1815 has better stability in high-temperature acid and alkali baths compared to other EO number products, making it suitable for formulating high-temperature leveling agents and acid dyeing auxiliaries. When both low foam and emulsification are needed: For foam-sensitive formulations such as metalworking fluids and agrochemical preparations, AC-1815 offers advantages over AC-1820\/1830.

Accepted Answer

The usage method of Octadecylpolyoxyethylene Ether AC-1815 varies depending on the application field. It is usually dispersed with water or solvent first before being added to the formulation system. The database does not have a unified recommended dosage, and typical dosages vary greatly across different fields. The optimal proportion needs to be determined through experiments. Detailed Description Octadecylpolyoxyethylene Ether AC-1815 (CAS No.: 26635-75-6) appears as a white to light yellow waxy solid or paste (melting point 30~40°C). It is a special nonionic surctant that exhibits nonionic characteristics under neutral or alkaline conditions, while it can show cationic characteristics under acidic conditions. Its HLB value is about 14~15, easily soluble in water and organic solvents, with good chemical compatibility and wide applicability. Before use, it is recommended to heat the product to 40~50°C to soften or melt it for easier taking and feeding. When feeding, it can be directly added to warm water (40~60°C) and stirred to dissolve, preparing a mother liquor of a certain concentration, then added to the main system according to the formula ratio. It can also be mixed with oily components in the formulation before emulsification with the water phase. When used in an acidic system, AC-1815 converts to a cationic form, significantly enhancing its adsorption and conditioning softening properties. Since the Guoli Chemical product database does not include unified recommended dosage data, the following typical reference dosages in various fields are industry empirical values. The actual optimal dosage needs to be optimized by users through orthogonal experiments or gradient experiments based on their own formulation system and process conditions.

Detailed Explanation of Six Core Application Fields Application Industry Specific Process/Use Core Function Textile Printing and Dyeing High-temperature leveling agent, dyeing acid, antistatic agent Migration and retardation, static elimination, preventing color spots and color differences Synthetic Fibers Polyester/Acrylic/Nylon oil agents Smoothing and bundling, reducing friction coefficient, antistatic protection Metal Processing Cutting fluids, grinding fluids, rust prevention fluids Efficient emulsification, corrosion inhibition, lubrication and rust prevention Pesticide Formulations Emulsifiable concentrates, emulsion concentrates, microemulsions Emulsification and dispersion of organophosphate/pyrethroid active ingredients Daily Chemicals Shampoo, shower gel, conditioner Assisted emulsification, thickening, antistatic and softening Coatings and Inks Water-based and solvent-based coatings, printing inks Pigment wetting and dispersion, preventing floating and settling Application Recommendations In textile printing and dyeing applications, it is recommended to compound AC-1815 with other nonionic or anionic auxiliaries to achieve synergistic effects. Especially in high-temperature and high-pressure dyeing processes, its triple chemical resistance to acids, alkalis, and hard water maintains high activity under harsh conditions. In metalworking fluid formulations, its property of converting to cationic form under acidic conditions can be utilized to enhance adsorption film formation on metal surces and improve rust prevention effects. In pesticide formulations, AC-1815 shows good emulsification and dispersion capabilities for organophosphate and pyrethroid active ingredients. The recommended dosage should be determined through emulsification experiments based on the specific formulation system. In daily chemical formulations, AC-1815 can be used as an auxiliary emulsifier and viscosity regulator, helping to stably disperse oily components such as fragrances and silicone oils, while utilizing its cationic properties to impart antistatic and softening effects to hair and skin, reducing frizz and improving dry and wet combing performance.
