What is Biotin?

Biotin, also known as Vitamin B7, has the chemical formula; C10H16N2O3S. It appears as an odourless white crystalline powder. It is slightly soluble in water and soluble in alcohol, ether and an alkali hydroxide solution.

What is Biotin used for?

While present in foods such as; egg yolks, mushrooms, nuts, avocados, legumes, salmon, bananas, whole grains, yeast, kidneys and livers, biotin is typically synthesised into vitamin form. 

Biotin supplements claim to have positive effects on: 

  • Hair 
  • Skin 
  • Nails 
  • Liver health
  • Nervous system health
  • Pregnancy and breastfeeding
  • Blood sugar regulation
Supplements claiming to promote healthy hair, skin and nails often contain Biotin as the key ingredient.

Biotin Hazards

The routes of exposure for biotin include inhalation, ingestion and skin and eye contact. 

Inhalation of biotin is not thought to produce respiratory tract irritation, however good hygiene practices are encouraged to minimise exposure in an occupational setting. Individuals with existing respiratory diseases such as emphysema and chronic bronchitis as well as circulatory/nervous system or kidney damage, may incur further disablement if excessive concentrations are inhaled. 

Biotin is not considered to be harmful by ingestion, however the material may still be damaging to the health of the individual where they have existing kidney and liver damage. Ingestion of insignificant quantities is not thought to be of concern. Larger doses of the material may cause nausea and vomiting.

Skin exposure to biotin is not thought to cause skin irritation, however good hygiene practices, including glove usage, are encouraged to minimise exposure in an occupational setting.

Eye exposure is expected to cause discomfort characterised by tearing and redness with slight abrasive damage also a possibility. 

Biotin Safety

If inhaled, remove the patient from the contaminated area to the nearest fresh air source. Encourage the patient to blow their nose to clear their breathing passages. Seek medical attention if irritation persists. 

If swallowed, immediately drink a glass of water. First aid is not generally required.

If skin exposure occurs, remove all contaminated clothing and footwear and immediately flush the affected area with plenty of soap and running water. Seek medical attention in the event of irritation. 

If the chemical is exposed to the eyes, flush the eyes out immediately with water, remembering to wash under the eyelids. Contact lenses should only be removed by a skilled professional. Seek medical attention if irritation persists.

Biotin Safety Handling

Emergency eyewash fountains should be accessible in the immediate area of the potential exposure to the chemical and there should always be adequate ventilation to remove or dilute any air contaminants to prevent overexposure (install local exhaust if necessary). 

The PPE recommended when handling biotin includes, safety glasses with side shields, chemical goggles, filter dust respirators, PVC/rubber gloves, overalls and lab coats. Barrier cream is also recommended to prevent skin irritation during handling. 

Biotin is safe for human consumption in controlled amounts, but this does not mean it is harmless. Always refer to your SDS to prevent incorrect handling of biotin and other chemicals.
