Glycerine Ethoxylate Grades Explained: Selecting GL7, GL12, GL18 and GL26 for Different Applications

When selecting Glycerine Ethoxylate ( CAS No.: 31694-55-0) customers usually consider the relationship between ethoxylation level and final application requirements. Different EO levels can affect the product’s hydrophilicity, polarity, water compatibility and interaction with other ingredients.

Polykem supplies Glycerine Ethoxylate grades including GL7, GL12, GL18 and GL26. These grades are available for customers looking for different levels of emulsification, wetting, solubilization and formulation compatibility.

How Ethoxylation Level Influences Performance

The EO number is one of the main factors used to distinguish Glycerine Ethoxylate grades. Similar to other nonionic surfactants such as Alcohols C13 ethoxylate, different ethoxylation levels can influence hydrophilicity, compatibility and application performance.

Lower EO grades usually maintain better compatibility with oil-based materials, while higher EO grades are more commonly considered when stronger water dispersibility, emulsification or solubilization is needed.

However, grade selection is not only based on EO number. Customers also need to consider the formulation environment, other ingredients, required processing performance and final product requirements.

GL7 and GL12: Grades with Balanced Compatibility

GL7 and GL12 are commonly considered for applications where balanced compatibility and flexible performance are required.

These grades can be used in systems where both oil-phase interaction and moderate water compatibility are important. They are often selected when customers need a nonionic surfactant that can work together with other ingredients without significantly changing the original formulation system.

GL18 and GL26: Higher Hydrophilic Grades

Compared with lower EO grades, GL18 and GL26 provide stronger hydrophilic characteristics. They are considered for applications where better water compatibility, dispersion or solubilization performance is required.

Higher EO grades are often used in systems where the surfactant needs to perform more effectively in water-based environments.

Choosing the Right Glycerine Ethoxylate Grade

There is no single “best” Glycerine Ethoxylate grade for all applications. The suitable grade depends on the balance between hydrophilic and hydrophobic properties, application conditions and formulation requirements.
