Lab Safety Rules Associated with Menthol

 

Hello, I'm the minty Lab assistant. I would like to inform you that dealing with any chemical substance must start with an overview on its safety rules and so is for menthol:

 

   

 So Get Ready To Know MENTHOL 
 

1. Product Identification

  

Synonyms             : 5-Methyl-2-(1-methylethyl) cyclohexanol
Molecular Weight  : 156.27 
Chemical Formula C10H20O

                             

 

2. Composition/ Ingredients

 

Ingredients             Percent          Hazardous

Levo Menthol              100%                 Yes

 

3. Hazards Identification: DANGER!

 

 MAY BE FATAL IF SWALLOWED.

HARMFUL IF INHALED.

CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT.

 MAY CAUSE ALLERGIC REACTION. 

  

4. Potential Health Effects

 

a- Inhalation:
Vapors or dust can be irritating in large amounts.

The normal sensation is that of a pleasant odor.

It may cause allergic reaction in sensitive individuals. 

b- Ingestion:
Toxic.

Estimated fatal dose, average human, is 2 g.

General gastrointestinal upset can occur with pain, vomiting, vertigo, drowsiness and coma.

Death from respiratory failure can result in cases of severe poisoning. 

Note that:  (-)-Menthol has low toxicity:

Oral (rat) LD50: 3300 mg/kg; Skin (rabbit) LD50: 15800 mg/kg. 

c- Skin Contact:
Mild irritant but may cause pain or inflammation on sensitive areas of the skin. 

d- Eye Contact:
Irritant.

It can cause reddening and tearing. 

e- Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired respiratory function may be more susceptible to the effects of the substance.

Menthol may give rise to hypersensitivity reactions including contact dermatitis.

 

  
6. Safety Precautions that Should Be Taken Upon Using MENTHOL 

  

First Aid Measures  
     

a- Inhalation:
Remove to fresh air.

If not breathing, give artificial respiration.

 If breathing is difficult, give oxygen.

Get medical attention. 

b- Ingestion:
Induce vomiting immediately as directed by medical personnel.

Never give anything by mouth to an unconscious person. 

c- Skin Contact:
Immediately flush skin with plenty of soap and water.

Remove contaminated clothing and shoes.

Get medical attention.

Wash clothing before reuse.

Thoroughly clean shoes before reuse. 

d- Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally.

Get medical attention immediately. 

e- Fire Fighting Measures:
As with most organic solids, fire is possible at elevated temperatures or by contact with an ignition source.

Fire may produce toxic fumes. 

f- Explosion:
Not considered to be an explosion hazard. 

g- Fire Extinguishing Media:
Dry chemical, foam, water or carbon dioxide.

Water spray may be used to keep fire exposed containers cool.
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. 

h- Accidental Release Measures:

Remove all sources of ignition.

Ventilate area of leak or spill.

Wear appropriate personal protective equipment.

Spills: Clean up spills in a manner that does not disperse dust into the air.

Reduce airborne dust and prevent scattering by moistening with water. 

i- Handling and Storage:

Keep in a tightly closed container, stored in a cool, dry, ventilated area.

Protect against physical damage.

Isolate from incompatible substances.

Containers of this material may be hazardous when empty since they retain product residues (dust, solids);

Observe all warnings and precautions listed for the product.  

 

 

NOW, let's Guess ...

 

What happens if Menthol is released into the environment?
 

When Menthol is released into the soil, this material is not expected to leach into groundwater. It may evaporate to a moderate extent.

When Menthol is released into the air, menthol is expected to be readily degraded by reaction with photochemically produced hydroxyl radicals.

When Menthol is released to water, it is expected to quickly evaporate.

  

 

Note : The small amount of menthol that is used in food like candies is not fatal and it is safe. Safety rules should be followed when you deal with or handle pure menthol.
