Common Name(s): Calcium lignosulfonate,lignosulfonate calcium,wood pulp lignosulfonate ca
CAS Number: 8061-52-7
DESCRIPTION
What It Does: Helps ingredients disperse evenly in water-based products and can help hold compressed powder formulas together.
Why It's Used: Used as a natural-origin dispersant in water-based and powder formulations; derived from sustainable wood pulp processing.
How It Works: Lignosulfonate polymers adsorb onto particle surfaces through phenolic aromatic groups; sulfonate charges create electrostatic stabilization; calcium counterion provides bridging flocculation control.
Typically Found In: Dispersant systems,powder formulations,binders,industrial cosmetic manufacturing

Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Generally non-irritating. plant-derived natural origin.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile. ewg score: 1โ2.
Works Well With: Inorganic pigments,powders,water-based systems
Avoid Combining With: Avoid with cationic ingredients (charge neutralization potential)
SCIENTIFIC NOTE
Lignosulfonates are aromatic polyelectrolytes derived from lignin, the second most abundant natural polymer; calcium form has moderate water solubility and is used as an economic natural-origin dispersant.
