Product type
Fatty alcohol ethoxylates are non-ionic surfactants derived from the ethoxylation of fatty alcohols. They are typically produced by reacting fatty alcohols with ethylene oxide, resulting in compounds that have both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties. This unique structure allows fatty alcohol ethoxylates to effectively reduce surface tension and improve the wetting, emulsifying, and dispersing properties of formulations.
| Chemical structure | Ethoxylated fatty alcohols |
| Hydrophilic-lipophilic balance (HLB) | Typically ranges from 10 to 15 |
| Appearance | Clear to slightly cloudy liquid or solid |
| Solubility | Soluble in water and various organic solvents |
| Typical carbon chain length | C8 to C18 |
When selecting fatty alcohol ethoxylates, consider the desired hydrophilic-lipophilic balance (HLB) for your formulation, as this will influence the surfactant's performance in emulsification and wetting. Specify the carbon chain length based on the application, as different lengths can affect solubility and compatibility. Additionally, inquire about any relevant certifications or grades that may be necessary for your specific use case, and provide estimated quantities to receive accurate quotes.
