As they are non ionic, these products are hardly influenced by acid, alkali, salt, etc. As we have a wide variety of types of products, customers can select the products that exhibit the emulsifying properties that are optimal for their needs.

Hydrophobic Group Type Product Name (Series) Function and Application Characteristics
Castor oil Newcol® 1500 Series Emulsification (animal and vegetable oil), dispersion and solubilization PRTR not applicable
Polycyclic aryl Newcol® 600 Series Emulsification, dispersion and cleaning Low foaming,
PRTR not applicable
Newcol® 700 Series Emulsification, dispersion and solubilization Low foaming,
PRTR not applicable
Newcol® 2600 Series Emulsification and dispersion Low foaming,
PRTR not applicable

Satisfactory dispersion stability is demonstrated by the bulk of hydrophobic group and by surface absorptivity.

Newcol® 700 Series is a representative product of us and has an aromatic structure with low foaming characteristics. Its effectiveness with regard to emulsion polymerization stability and pigment dispersion is excellent.
