Dihydrogenated Tallow Base Diammonium Chloride (often designated as DHTDMC or DHTDMAC, and registered under CAS No. 61789-80-8) is a prominent double-chain quaternary ammonium compound. Derived from processed animal fats, specifically tallow fatty acids which are hydrogenated to secure fully saturated carbon networks, this chemical contains predominantly C16 (palmitic) and C18 (stearic) alkyl chains. This structure yields superior hydrophobic properties compared to single-chain surfactant variants.
The cationic configuration enables strong adsorption onto negatively charged solid surfaces (such as cellulosic fibers, human hair keratin, and silica-containing clays). Consequently, it creates a molecular barrier that significantly reduces surface friction and static charges. In its refined industrial state, the compound appears as a white-to-light-yellow paste or dispersion, standardly diluted with isopropyl alcohol or ethanol to facilitate storage and handling.

The global surfactant market has witnessed a significant structural transition in recent years. While regional regulations in the European Union and North America have restricted the direct, untreated release of legacy quaternary salts into domestic waterways, DHTDMC remains indispensable across several high-performance industrial sectors.
In oilfield chemical formulations, organoclay syntheses, and specialized industrial coatings, the demand for DHTDMC continues to rise. The compound forms the hydrophobic foundation of organophilic bentonite, which is essential for stabilizing oil-based drilling fluids under high-temperature, high-pressure (HTHP) conditions. The market has shifted toward high-active-content concentrates, which minimize shipping volumes and significantly lower carbon emissions associated with global logistics.

The CAS registry number is 61789-80-8. This material is a double-chain quaternary ammonium compound derived from natural tallow, containing saturated C16 (palmitic) and C18 (stearic) carbon chains linked to a dimethyl ammonium chloride polar head group. It is commonly designated as DHTDMC or DHTDMAC.
DHTDMC features highly stable carbon-nitrogen bonds, offering strong thermal and hydrolytic stability across wide pH ranges. Unlike esterquats (such as HEQ or TEQ), which can degrade over time in water-based formulas, DHTDMC retains its viscosity and conditioning performance during long-term storage in demanding climates.
Key technical indicators include: active matter content (typically 75% or 90%), free amine concentration, pH value, color index (APHA/Hazen), and moisture content. Low free-amine percentages ensure minimal odor and reduce the risk of dermal irritation in skin-contact applications.
DHTDMC should be stored in a cool, well-ventilated warehouse, kept away from direct sunlight, open flames, and strong oxidizing agents. Because it contains flammable solvent systems (like isopropyl alcohol) to keep the paste fluid, fire safety systems and earthing connections for static control are required during material transfers.
Yes. Our production facilities can adjust active concentration ranges between 70% and 90% by incorporating custom solvent matrices (e.g., ethanol, IPA, or propylene glycol) to meet specific formulation and handling requirements.
In organoclay synthesis, DHTDMC participates in cationic exchange with inorganic sodium bentonite. The cationic nitrogen binds to the silicate layers, while the hydrophobic tallow carbon tails extend outward, converting hydrophilic clay into organophilic particles that gel and suspend oil-based solvent systems.
We supply full export documentation, including COA, MSDS/SDS compliant with GHS standards, and support for regional compliance declarations (such as REACH, TSCA, and IECIC listings) to facilitate international customs clearance.
For standard specifications, production and port delivery are completed within 14 to 21 days from order confirmation. Custom solvent configurations or specialized active concentrations may extend this window to 30 days.
Fibers typically carry a negative surface charge due to friction or chemical treatments. The cationic nitrogen head of the DHTDMC molecule adsorbs onto the fiber surface, while the hydrophobic hydrocarbon tails align outward to form a thin film. This layer reduces surface resistivity and friction, preventing static charge accumulation.
Quaternary ammonium salts like DHTDMC bind tightly to suspended soils and biomass in wastewater treatment systems. This adsorption removes them from the water column, allowing them to undergo slow biodegradation by specialized soil and sediment microflora.
