DESCRIPTION: |
Sorbic Acid (also called chemically 2,4-hexadienoic acid ), a white crystalline powder or granule form for dust free, is an unsaturated fatty acid which has two double bonds in conjugation that is, two double bonds separated only by one single bond. |
|

|
APPLICATION |
||
|
It and its salts (potassium sorbate, calcium sorbate ; its salts are used according to differences in solubility.) are used as preservatives in wide range of food products as well as in their packaging materials, since they are characterized by their broad effectiveness to inhibit molds, yeast, and many bacteria growth in food. Potassium sorbate, white to slightly yellow crystalline powder, is the potassium salt of sorbic acid and is much more soluble in water than the acid. Potassium sorbate will releases back sorbic acid if dissolved in water. It is effective up to pH 6.5 but effectiveness increases as the pH decreases. The lower the pH value of the product the lower amount of Sorbic Acid or Potassium Sorbate is needed for preservation. Its industrial applications include use in coating industry to improve gloss and in rubber industry. |

Section 4: First Aid Measures
Eye Contact:
Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention.
Skin Contact:
After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin
with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.
Cover the irritated skin with an emollient. If irritation persists, seek medical attention. Wash contaminated
clothing before reusing.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention.
Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
Serious Inhalation: Not available.
Ingestion:

Section 6: Accidental Release Measures
Small Spill:
Use appropriate tools to put the spilled solid in a convenient waste disposal container. If necessary: Neutralize
the residue with a dilute solution of sodium carbonate. Finish cleaning by spreading water on the
contaminated surface and dispose of according to local and regional authority requirements.
Large Spill:
Use a shovel to put the material into a convenient waste disposal container. Neutralize the residue with a dilute
solution of sodium carbonate. Finish cleaning by spreading water on the contaminated surface and allow to
evacuate through the sanitary system.
Section 7: Handling and Storage
Precautions:
Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the
residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not breathe dust.
Wear suitable protective clothing In case of insufficient ventilation, wear suitable respiratory equipment If
ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes
Storage:
Keep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly
closed. Keep in a cool, well-ventilated place. Combustible materials should be stored away from extreme heat
and away from strong oxidizing agents.
Section 8: Exposure Controls/Personal Protection
Engineering Controls:
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal Protection:
Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
