Calcium peroxide Chemical Properties,Uses,Production

Chemical Properties

White or yellowish powder; odorless; almost tasteless. Decomposes at approximately 200C. Almost insoluble in water; soluble in acids with formation of hydrogen peroxide. Available oxygen 22.2% (min 13.3% in technical grade).

Chemical Properties

Calcium peroxide is a grayish-white or yellowish odorless crystalline solid.


Calcium Peroxide is a dough conditioner which exists as a white or yellowish powder or granule that is insoluble in water. it improves dough strength, grain, and texture, and increases absorption and crumb resiliency. it is used in bakery products.


Stabilizer for rubber.

General Description

A grayish white granular material. Used in baking, in medicine, in bleaching oils.

Air & Water Reactions

Isoluble in water and slowly decomposed by water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].

Reactivity Profile

Calcium peroxide is an explosion hazard if mixed with finely divided organic matter. Noncombustible but accelerates the burning of combustible material: mixtures of combustible material and the peroxide can be ignited by friction or contact with moisture. Mixtures with polysulfide polymers may ignite. Decomposes rapidly above 200° C. Strongly basic Reacts with water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].


Strong oxidizing agent. Dangerous fire risk in contact with organic materials. Irritating in con- centrated form.

Health Hazard

Inhalation of dust irritates nose and throat. Dust also irritates eyes and skin on contact and irritates mouth and stomach if ingested.

Fire Hazard

Behavior in Fire: Can increase severity of fire. Containers may explode.

Safety Profile

Irritating in concentrated form. Will react with moisture to form slaked lime. Flammable if hot andmixed with finely dwided combustible material. Mixtures with oxiduable materials can also be ignited by grinding and are explosion hazards. A strong alkali. An oxidizer. Mixtures with polysulfide polymers may ignite. See also CALCIUM COMPOUNDS, CALCIUM HYDROXIDE, and PEROXIDES, INORGANIC.

Potential Exposure

Calcium peroxide is used as a seed disinfectant, an antiseptic, and a rubber stabilizer.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 30 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
