Product Overview
Denatonium Benzoate Powder is an extremely bitter quaternary ammonium compound used as a bittering agent and aversive additive in industrial and consumer product safety applications.
It is usually supplied as white crystalline powder, and buyers often review CAS number, assay, bitterness performance, solubility, particle size, heavy metals, residual solvents, and documentation scope before technical or commercial evaluation.
It is commonly considered for denatured alcohol, household products, automotive fluids, industrial chemicals, and anti-ingestion applications, with COA and SDS/MSDS available for sourcing reference.

Applications
Denatured Alcohol
Used as a bittering agent in denatured alcohol systems where an aversive additive is required.
Household Products
Used in cleaners, detergents, and maintenance products to discourage accidental ingestion.
Automotive Fluids
May be used in antifreeze or technical liquids where bittering and anti-ingestion positioning are required.
Industrial Chemicals
Reviewed as an aversive agent for misuse prevention in industrial chemical products.
How to Choose the Right Grade / Form
Industrial Bitterant Grade
For industrial formulations, choose material with clear assay, solubility, residual solvent, and heavy metal specifications.
Denaturing Grade
For denatured alcohol applications, confirm denaturing rules, required concentration, solvent compatibility, and documentation scope.
Household Product Grade
For household and consumer safety applications, review assay, solubility, odor impact, compatibility, and safety labeling requirements.
Confirm Specification
Verify identity, solvent compatibility, application compliance, use level, and local restrictions before commercial use.
Technical & Formulation Notes
Technical Notes
Denatonium benzoate is selected when an extremely bitter additive is required to discourage accidental ingestion or misuse of non-food products.
For procurement review, buyers should confirm CAS 3734-33-6, assay, appearance, solubility, bitterness performance, residual solvents, heavy metals, and application-specific compliance before order confirmation.
Manufacturing & Process
Commercial denatonium benzoate powder is produced through controlled chemical synthesis, purification, crystallization, drying, sieving, and packaging.
Batch consistency should be evaluated through appearance, identification, assay, loss on drying, residual solvents, and impurity testing according to the agreed specification.
Compatibility / Formulation Notes
For denatured alcohol, solubility, concentration, bitterness performance, and local denaturing regulations should be confirmed before use.
For household products, compatibility with surfactants, solvents, fragrances, dyes, and preservatives should be evaluated in the final formula.
For automotive fluids, formulators should test stability, solubility, and performance under the intended temperature and storage conditions.
Denatonium benzoate should not be positioned as a food, feed, supplement, or nutrition ingredient.
Extended QC & Test Items
Extended quality review may include appearance, identification, assay, solubility, loss on drying, residue on ignition, residual solvents, heavy metals, lead, arsenic, cadmium, mercury, particle size, and microbiological items where required.
