What is organoclay?
Organoclay (also organophilic clay or organobentonite) is a chemically modified bentonite clay. Natural sodium bentonite is treated with quaternary ammonium salts via ion-exchange, converting it from hydrophilic to organophilic — capable of swelling and gelling in organic solvents and oils. It is used as a rheology modifier, anti-settling agent, and thixotropic additive.

Organoclay is used as a rheology modifier in paints and coatings (anti-settling, sag control), oil-based drilling fluids (viscosifier), lubricating greases (thickener), printing inks, adhesives and sealants, cosmetics, and water treatment (contaminant adsorption).
How do I disperse organoclay?
Add organoclay to the solvent phase, then add polar activator (95% ethanol at 30–50% of organoclay weight). Mix at high shear (1,000–3,000 rpm) for 10–15 minutes. Allow 10 minutes for gel formation. Self-activating grades (CP-180B, CP-992) skip the activator step.

CP-34 and CP-40 are both DMDA-modified montmorillonite organoclay for solvent-based systems. CP-34 performs best in aromatic and moderate-polarity solvents. CP-40 has broader compatibility including aliphatic solvents. Both require polar activator dispersion.
What is a self-activating organoclay?
Self-activating (SA) organoclay has a polar activator compound (propylene carbonate) pre-coated on the surface during manufacturing. This allows direct dispersion in solvent or oil without adding external polar activator — simplifying formulation. CP-180B and CP-992 are self-activating grades.
What is the minimum order quantity (MOQ)?
Standard MOQ is 1 FCL (one 20-foot container), approximately 17–20 MT depending on packaging. LCL shipments (500 kg – 5 MT) are available at higher unit cost. Free samples (200g–2 kg) are available by courier with no minimum.
What is the organoclay HS code?
Organoclay is most commonly classified under HS code 3824.99 (chemical preparations, not elsewhere classified). Some markets use 2508.10 (bentonite). Confirm with your customs broker. We provide product descriptions and COA to support customs clearance.
Read more → Is CP organoclay equivalent to other commercial organoclay brands?
Yes. CP organoclay uses the same DMDA-modified montmorillonite chemistry and wet-process manufacturing as all equivalent commercial grades. We offer free side-by-side comparison samples so you can verify performance in your own formulation before switching.
Read more → What certifications does CP Organoclay have?
CP Organoclay is ISO 9001:2015 certified. Drilling grade products (CP-982, CP-992) are tested to API 13A Section 14. SGS third-party analysis is available on request. Full TDS, SDS, and COA are provided with every shipment.
Read more → Can organoclay be used in waterborne coatings?
Standard solvent-based organoclay does not disperse in water. For waterborne coatings, use CP-EW — a specially modified water-dispersible organoclay that provides thixotropy and suspension in aqueous systems.
Read more → How much organoclay should I add?
Typical treat rates: solvent-based paints (0.3–1.2%), oil-based drilling fluids (1.5–3.5% by volume), lubricating greases (8–15% on base oil weight), printing inks (0.5–2.0%), cosmetics (0.5–2.0%). Contact our technical team for guidance on your specific application.
What is the difference between organoclay and bentonite?
Bentonite is a natural hydrophilic clay that swells in water. Organoclay is chemically modified bentonite made organophilic (compatible with oils and solvents) by replacing interlayer cations with quaternary ammonium salts. They serve different applications.
