Hand Sanitizer Guide: Types, Usage, and Safety
Hand sanitizer is an antiseptic product applied to hands to kill or inactivate disease-causing microorganisms. It serves as a convenient alternative to handwashing with soap and water, especially when clean water is not available. This guide provides essential information for parents, caregivers, and healthcare professionals on safe and effective use of hand sanitizers in pediatric care.
Purpose and Where Hand Sanitizers Are Used
Hand sanitizers reduce the number of bacteria, viruses, and other microorganisms on hands. They are particularly useful in:
- Healthcare facilities (hospitals, clinics, pediatric offices)
- Schools and daycare centers
- Public transportation and travel
- Restaurants and food preparation areas
- Shopping centers and public spaces
- Home settings when soap and water are unavailable
- After touching potentially contaminated surfaces
Important: Hand sanitizers are effective against many germs but do not eliminate all types of harmful organisms. They work best on clean hands and are less effective when hands are visibly dirty or greasy.
Types of Hand Sanitizers
Based on Active Ingredient
| Type | Active Ingredient | Effectiveness |
|---|---|---|
| Alcohol-Based | Ethanol (60-95%), Isopropanol (60-95%) | Highly effective against most bacteria, viruses, and fungi |
| Non-Alcohol Based | Benzalkonium chloride, Triclosan | Less effective, not recommended by most health authorities |
Based on Form
- Gel: Most common form, easy to apply, stays on hands during rubbing
- Foam: Pre-lathered, uses less product, popular for children
- Liquid: Spreads quickly, may drip if too much is used
- Wipes: Convenient for travel, allows cleaning of surfaces too
Based on Dispensing Method
- Pump bottles: Portable, various sizes (50ml to 500ml)
- Wall-mounted dispensers: Common in healthcare settings
- Automatic/touchless dispensers: Reduce cross-contamination
- Pocket-sized bottles: Travel-friendly (typically 30-60ml)
Recommended for Children: Alcohol-based hand sanitizers with 60-95% alcohol concentration are most effective. The World Health Organization and Centers for Disease Control recommend alcohol-based formulations for hand hygiene.
How to Use Hand Sanitizer: Step-by-Step Guide
Step 1: Check that hands are not visibly dirty or greasy. If dirty, wash with soap and water first.
Step 2: Apply the product to the palm of one hand. Use enough to cover all hand surfaces (read product label for amount, typically 3-5ml or a coin-sized amount).
Step 3: Rub hands together, covering all surfaces:
- Palm to palm
- Between fingers and finger webs
- Back of hands
- Fingertips and under nails
- Thumbs
- Wrists
Step 4: Continue rubbing until hands are completely dry (typically 20-30 seconds for alcohol-based sanitizers).
Step 5: Do not wipe or rinse hands. Let the sanitizer evaporate naturally for maximum effectiveness.
When to Use Hand Sanitizer
- Before eating or handling food
- After using public transportation
- After touching shared objects or surfaces
- After visiting public places
- Before and after visiting someone who is sick
- When soap and water are not available
When Handwashing with Soap and Water is Necessary
- When hands are visibly dirty or soiled
- After using the toilet
- After changing diapers
- After contact with bodily fluids (vomit, blood, urine)
- After handling chemicals or pesticides
- Before preparing or cooking food
Precautions and Safety Measures
Critical Safety Warning: Hand sanitizers are for external use only. Ingestion can cause alcohol poisoning, especially in young children. Keep out of reach of unsupervised children.
Age-Specific Precautions
| Age Group | Safety Guidelines |
|---|---|
| Under 2 years | Consult pediatrician before use. Adult supervision required. Prefer handwashing with soap and water. |
| 2-5 years | Use only under direct adult supervision. Apply sanitizer for the child. Ensure hands are dry before touching face or mouth. |
| 6-12 years | Teach proper technique. Supervise to prevent ingestion or contact with eyes. Monitor for allergic reactions. |
| Above 12 years | Can use independently with proper education on safety and technique. |
General Safety Precautions
- Never allow children to drink or taste hand sanitizer
- Avoid contact with eyes. If contact occurs, rinse immediately with water for 15 minutes
- Do not use near open flames or heat sources (alcohol-based sanitizers are flammable)
- Stop use if skin irritation or rash develops
- Do not use on broken skin, wounds, or burns
- Keep containers tightly closed when not in use
- Use in well-ventilated areas to avoid inhaling fumes
- Check expiration dates before use (effectiveness decreases after expiry)
- Avoid flavored or scented sanitizers that might attract children to taste them
Potential Dangers and Adverse Effects
- Alcohol poisoning: Can occur if swallowed, symptoms include confusion, vomiting, drowsiness, breathing problems
- Skin irritation: Dryness, cracking, dermatitis with frequent use
- Eye irritation: Pain, redness, temporary vision problems if splashed in eyes
- Fire hazard: Alcohol-based sanitizers can ignite if exposed to flames or sparks
- Respiratory irritation: Inhaling fumes in poorly ventilated spaces
- Allergic reactions: Rare but possible with certain ingredients
Emergency Action: If a child swallows hand sanitizer, call poison control immediately or seek emergency medical care. Do not induce vomiting unless instructed by medical professionals.

Frequently Asked Questions
Is hand sanitizer safe for babies?
Hand sanitizers should be used cautiously in children under 2 years old and only under adult supervision. Handwashing with soap and water is preferred for infants and toddlers. Consult your pediatrician before regular use.
Can hand sanitizer replace handwashing?
No. Hand sanitizers are effective but do not replace handwashing with soap and water, especially when hands are visibly dirty or after using the toilet. Handwashing is always the gold standard.
How much hand sanitizer should be used?
Use enough to cover all hand surfaces completely, typically 3-5ml or a coin-sized amount. The product should take 20-30 seconds to dry when rubbed properly.
Does hand sanitizer kill all germs?
No. Alcohol-based sanitizers are effective against most bacteria and many viruses but may not eliminate all types of germs, including certain parasites and bacterial spores. They are also less effective on dirty or greasy hands.
What if my child accidentally swallows hand sanitizer?
Call poison control immediately or seek emergency medical care. Even small amounts can cause alcohol poisoning in children. Do not wait for symptoms to appear.
Can hand sanitizer cause dry skin?
Yes. Frequent use can dry out skin. Choose sanitizers with added moisturizers, and apply hand lotion regularly. If severe dryness or cracking occurs, reduce frequency and consult a healthcare provider.
Are non-alcohol hand sanitizers effective?
Non-alcohol sanitizers are generally less effective than alcohol-based products. Health organizations worldwide recommend alcohol-based sanitizers with 60-95% alcohol content for optimal germ reduction.
Do I need to wash hands after using hand sanitizer?
No. Let the sanitizer dry completely on hands without washing or wiping. However, after several applications or when hands become visibly dirty, wash with soap and water.
Can hand sanitizer expire?
Yes. Hand sanitizers have an expiration date, typically 2-3 years from manufacture. After expiration, alcohol content may decrease, reducing effectiveness. Check dates before use.
Is it safe to use hand sanitizer around food?
Yes, when hands are completely dry. Alcohol-based hand sanitizers are safe for use before handling food. Ensure hands are fully dry (20-30 seconds) before touching food items.
Can children develop resistance to hand sanitizers?
No. Unlike antibiotics, alcohol-based hand sanitizers work through physical mechanisms that do not lead to bacterial resistance. They remain effective with regular use.
Should I use hand sanitizer after touching pets?
Hand sanitizer can be used, but handwashing with soap and water is preferred after contact with pets, especially before eating or touching your face, as it removes dirt and allergens more effectively.
Recommendations for Healthcare Settings
- Follow WHO or local health authority guidelines for hand hygiene protocols
