Sodium Lignosulfonate (Wood Pulp)

CAS：8061-51-6

Product Introduction

Sodium Lignosulfonate is an anionic polymer surfactant produced from high-quality wood pulp lignin through sulfonation, purification, concentration and drying. It appears as brownish yellow to tan free-flowing powder, readily soluble in water. With stable performance, it exhibits excellent dispersibility, adhesion, chelation, water reduction and emulsifying properties. Non-toxic and eco-friendly, it is a versatile and renewable industrial additive with wide applications.
