Product Safety Summary of Sodium bicarbonate

General statement

This Product Safety Summary is intended toprovide a general overview of the chemical

substance. It constitutes basic information and is

not intended to provide emergency responseinformation, medical information, treatmentinformation or otherwise in-depth safety and

health information, which can only be found in therelevant Safety Data Sheet (SDS) or the MaterialSafety Data Sheet (MSDS), as the case may be.

Overall summary

Sodium bicarbonate is an odorless whitecrystalline solid.

The substance has a very wide range of

applications, which include use in feed, cosmetics,pharmaceuticals, and industrial applications.

Sodium bicarbonate is safe when ingested.

However ingestion of large quantities may causeirritation of the intestine, nausea, vomiting, anddiarrhea. Sodium bicarbonate is not toxic when

breathed in, or via skin contact. It is not irritatingto the skin or eye and does not provoke allergicreactions.

It is not toxic following repeated exposure and has

shown no indication of mutagenicity,carcinogenicity or effect on pre-natal development

of the embryo and fetus in toxicological testing.

Sodium bicarbonate is classified as Generally

Recognized As Safe (GRAS) by the US Food and

Drug Administration.

Sodium bicarbonate is not considered to be toxic

to the environment.

Chemical identity

Chemical name: Sodium hydrogen carbonate

Common name: Baking soda

CAS number: 144-55-8

Molecular weight: 84 g/mol

Uses

Sodium bicarbonate has a very wide range ofapplications, which include use in feed, cosmetics,

pharmaceuticals, and industrial applications. It

can be used for example as a pH regulator, for therelease of CO2and as a mild abrasive.

Physical properties

Sodium bicarbonate is a white crystalline solidwithout any odor. It is neither flammable norexplosive.

It is soluble in water (93.4 g/L at 20C and pH =

8.4), non-volatile and decomposes at

temperatures greater than 50C. In water, sodiumbicarbonate undergoes a complete dissociation

into sodium and bicarbonate ions.

Health effects

When sodium bicarbonate comes into contact with

body fluids, it dissociates into sodium and

bicarbonate ions. Sodium is an essential nutrientand bicarbonate is a component of the buffer that

regulates the acidity of the body. When ingested,

sodium bicarbonate is neutralized in the stomachby the gastric acid.

Sodium bicarbonate is safe when ingested.However ingestion of large quantities may cause

irritation of the intestine, nausea, vomiting, and

diarrhea. Sodium bicarbonate is not toxic whenbreathed in, or via skin contact. It is not irritatingto the skin or eye and does not provoke allergic

reactions.

It has no repeated dose toxicity as both sodium

and bicarbonate ions have normal physiological

roles in the body.

There are no indications that sodium bicarbonatecauses genetic effects or cancer. Toxicological

studies showed that sodium bicarbonate has no

effect on the pre-natal development of theembryo and fetus.

Sodium bicarbonate is classified as GenerallyRecognized As Safe (GRAS) by the US Food and

Drug Administration.

Environmental fate and impact

Due to its high water solubility and low volatility,

sodium bicarbonate will be found predominantly inthe aquatic environment.

In water, sodium bicarbonate dissociates into

sodium and bicarbonate ions. If the pH is

decreased then carbonic acid (H2CO3or CO2) canbe formed. If the concentration of CO2in water isabove the water solubility limit, the CO2will

distribute to the atmosphere. An addition ofbicarbonate to water will alter the pH towards avalue of 8.3.

If sodium bicarbonate is emitted to soil, it will

decompose to CO2and escape to the atmosphere,or precipitate as a calcium or metal carbonate,

form complexes or stay in solution in water.

Neither sodium nor bicarbonate has a tendency to

adsorb to the particulate matter or surfaces and

they do not accumulate in living tissues.

Both sodium and bicarbonate have a wide natural

occurrence.

Risk of human exposure

Exposure to sodium bicarbonate is possible in theworkplace environment during manufacturing and

use. Workers handling the substance should followGood Industrial Hygiene Practicesand wear theappropriate personal protective equipment, as

described in the Safety Data Sheet.

Consumers may be exposed to sodiumbicarbonate since it is used in many different

consumer products. Label instruction should be

respected.

Risk of environmental exposure

Exposure of the environment can occur from the

various industrial, professional, and consumer

uses. However, sodium bicarbonate is notconsidered to be environmentally hazardous or

toxic.

Because of the mild alkaline nature of thesubstance, it is recommended to contain and

isolate spills from waterways, sewers, and drains

and dilute the residues with large amounts ofwater.

Classification according to E.U. Regulation EC1272/2008 (CLP)

Sodium bicarbonate is currently not listed inAnnex VI to EU Classification, Labeling and

Packaging of Substances and Mixtures (CLP)

Regulation (EC) No 1272/200. Furthermore, theavailable data show that there is no need to

classify the substance as hazardous.
