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. | [CAS DataBase Reference]

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

1305-79-9(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
A grayish white granular material. Used in baking, in medicine, in bleaching oils. | [Reactivity Profile]
CALCIUM PEROXIDE(1305-79-9) 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]. | [Air & Water Reactions]
Isoluble in water and slowly decomposed by water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636]. | [Hazard]
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. | [Potential Exposure]
Calcium peroxide is used as a seed
disinfectant, an antiseptic, and a rubber stabilizer. | [Fire Hazard]
Behavior in Fire: Can increase severity of fire. Containers may explode. | [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 | [Shipping]
UN1457 Calcium peroxide, Hazard Class: 5.1;
Labels: 5.1-Oxidizer | [Incompatibilities]
Slow reaction with water or other forms
of moisture, releasing calcium hydroxide Calcium peroxide
is a strong alkali and a strong oxidizer. Incompatible with
reducing agents, including hydrides; acids, combustible
materials; polysulfide polymers. Rapid decomposition
》200C | [Description]
Calcium peroxide is a grayish-white or yellowish odorless crystalline solid. Molecular weight=72.1;Freezing/Melting point=275℃ (decomposes). HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 0, Reactivity 1. Insoluble in water. | [Chemical Properties]
Calcium peroxide is a grayish-white or
yellowish odorless crystalline solid. | [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).
| [Physical properties]
For all practical purposes, calcium peroxide is insoluble
in water but will dissolve in acid to form H2O2. When in
contact with water, it will immediately begin to decompose
releasing oxygen. | [Definition]
ChEBI: Calcium peroxide is a member of calcium oxides. | [storage]
Color Code—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flammables and combustibles. Prior to working with calciumperoxide you should be trained on its proper handling andstorage. Calcium peroxide must be stored to avoid contactwith combustible materials (such as wood, paper, oil, fuels,etc.) since violent reactions occur. Store in tightly closedcontainers. See OSHA Standard 1910.104 and NFPA 43ACode for the Storage of Liquid and Solid Oxidizers fordetailed handling and storage regulations. |
