Cobalt naphthenate Chemical Properties,Uses,Production

Chemical Properties

Black liquid

Chemical Properties

Cobalt naphthenate is a flammable brown powder or bluish-red solid; freezing/melting point = 140°C; flash point = 49°C; autoignition temperature = 276°C. Hazard identification (based on NFPA-704 M Rating System): Health 1, flammability 2, reactivity 0. Insoluble in water.

General Description

Cobalt naphthenate is a brown powder or a bluish-red solid. Cobalt naphthenate is easily ignited and once ignited can burn profusely. Cobalt naphthenate is used to make paints and varnish.

Air & Water Reactions

Highly flammable.

Reactivity Profile

COBALT NAPHTHENATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Fire Hazard

Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.

Contact allergens

Cobalt naphthenate is made by treating cobalt hydroxide or acetate with naphthenic acid. It is an accelerant in rubber, unsaturated polyester, and vinyl ester resins.

Safety Profile

Moderately toxic by ingestion. Flammable when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Cobalt naphthenate is used as a drying agent in paints, varnishes; inks, and for curing plastics.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy


UN2001 Cobalt naphthenate powder, Hazard Class: 4.1; Labels: 4.1-Flammable solid. UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required


Highly flammable; powder or dust can form an explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
