SAN X®, VANILLEX®, PEARLLEX®
Lignin is one of the principal components of wood and has unique properties. We are the only lignin manufacturer in Japan and we produce a wide range of lignin products. Our brands, SAN X®, VANILLEX® and PEARLLEX® are used in many industries.
Functions of lignin products
Lignin products have three functions: dispersing, binding and chelating.
- Dispersing
- Lignosulfonate is a high weight electrolyte containing sulfonate, carboxyl and phenol hydroxyl groups. It is absorbent to organic and inorganic particles chemically or physically, and keeps them dispersing stably due to its strong hydrophilic property and negative charges.
- Binding
- Lignosulfonate has a binding property since it is a high polymer. SAN X® has an excellent binding property since it contains not only lignosulfonate but also reduces sugar and sugar sulfonate.
- Chelating
- Lignosulfonate and sugar derivatives have a chelating property making hydrophilic or hydrophobic compounds since they contain sulfonate, carboxyl and phenol or alcohol hydroxyl groups and they are absorbent to polyvalent metal ions.
