## Understanding the Science Behind Hand Sanitizer
Before diving into the recipe, it’s crucial to understand how hand sanitizer works. The effectiveness of alcohol-based hand sanitizers relies on the alcohol’s ability to denature proteins and disrupt the cell membranes of bacteria and viruses. This process effectively kills or inactivates these microorganisms.
The Centers for Disease Control and Prevention (CDC) recommends using hand sanitizers with an alcohol concentration of at least 60% ethanol (ethyl alcohol) or 70% isopropanol (isopropyl alcohol, also known as rubbing alcohol) to ensure efficacy. This concentration range is crucial for optimal germ-killing power.
Adding a gelling agent, such as carbomer or aloe vera gel, creates a gel consistency that allows the sanitizer to stay on the hands longer, increasing its contact time with microorganisms. This prolonged contact time enhances the sanitizer’s effectiveness.
## Essential Ingredients
Here’s a list of the ingredients you’ll need to make your own gel alcohol hand sanitizer. It’s essential to use the correct concentrations and to source your ingredients from reputable suppliers:
* **Isopropyl Alcohol (99% concentration) or Ethanol (95% concentration):** This is the active ingredient that kills germs. Ensure you use the correct concentration to achieve the recommended alcohol percentage in the final product. **Important:** Do not use methanol (methyl alcohol), as it is toxic.
* **Aloe Vera Gel (Unscented and Pure):** This acts as a moisturizer and gelling agent. Choose a pure, unscented aloe vera gel to avoid unwanted additives or fragrances that could irritate the skin.
* **Optional: Essential Oils:** For fragrance and potential added benefits (e.g., tea tree oil for its antimicrobial properties), you can add a few drops of essential oils. However, be cautious, as some essential oils can cause skin irritation.
* **Optional: Glycerin or Other Humectant:** Glycerin is a humectant, which means it helps to draw moisture into the skin. Adding a small amount can help to prevent dryness caused by the alcohol.
## Necessary Equipment
Having the right equipment is essential for accurate measurements and safe handling of the ingredients:
* **Measuring Cups and Spoons:** Use accurate measuring cups and spoons to ensure the correct proportions of each ingredient.
* **Mixing Bowls:** Choose a non-reactive mixing bowl, such as glass or stainless steel.
* **Whisk or Stirring Utensil:** Use a whisk or stirring utensil to thoroughly combine the ingredients.
* **Funnel:** A funnel helps to easily transfer the finished hand sanitizer into bottles.
* **Bottles:** Use clean, empty bottles with secure lids or pump dispensers to store the hand sanitizer. Small, travel-sized bottles are convenient for on-the-go use.
* **Gloves:** Wear gloves to protect your skin from the high concentration of alcohol.
* **Eye Protection:** Wear safety glasses or goggles to protect your eyes from accidental splashes.
## Step-by-Step Instructions
Follow these detailed instructions to make your own gel alcohol hand sanitizer:
**Step 1: Prepare Your Workspace**
* Clean and disinfect your workspace with a disinfectant wipe or spray.
* Gather all the necessary ingredients and equipment.
* Put on your gloves and eye protection.
**Step 2: Measure the Alcohol**
* **For Isopropyl Alcohol (99%):** Measure 75 ml (2.5 ounces) of 99% isopropyl alcohol into your mixing bowl. This will result in a final concentration close to 70% after adding aloe vera.
* **For Ethanol (95%):** Measure 79 ml (2.7 ounces) of 95% ethanol into your mixing bowl. This will result in a final concentration close to 70% after adding aloe vera.
*Why these numbers? The calculations below show how to arrive at the correct measurement.*
*For Isopropyl Alcohol (99%):*
(amount of alcohol * alcohol concentration) + (amount of aloe * alcohol concentration) = desired final concentration
(75ml * .99) + (25ml * 0) = 74.25
74.25/ 100ml = 74.25%
*For Ethanol (95%):*
(amount of alcohol * alcohol concentration) + (amount of aloe * alcohol concentration) = desired final concentration
(79ml * .95) + (21ml * 0) = 75.05
75.05/100ml = 75.05%
*These calculations assume the aloe vera gel has an alcohol % of 0%. This is generally true, though some products may have a preservative alcohol. Review the contents of the aloe gel to ensure it won’t impact the target alcohol %. If the gel has any % of alcohol it will alter the amount of alcohol to add, as well as impact the effectiveness of the hand sanitizer.*
**Step 3: Add Aloe Vera Gel**
* Measure 25 ml (0.8 ounces) of aloe vera gel and add it to the mixing bowl.
**Step 4: Add Optional Ingredients (Essential Oils, Glycerin)**
* If using essential oils, add 2-3 drops to the mixture. Start with a small amount and adjust to your preference.
* If using glycerin, add ½ teaspoon (2.5 ml) to the mixture.
**Step 5: Mix Thoroughly**
* Use a whisk or stirring utensil to thoroughly mix the ingredients until they are completely combined and the mixture has a uniform consistency. This may take a few minutes.
**Step 6: Transfer to Bottles**
* Using a funnel, carefully transfer the finished hand sanitizer into clean, empty bottles. Be careful not to spill any.
* Securely close the lids or attach the pump dispensers to the bottles.
**Step 7: Label and Store**
* Label each bottle with the contents and the date it was made.
* Store the hand sanitizer in a cool, dark place away from direct sunlight and heat. This will help to preserve its effectiveness and prevent the alcohol from evaporating.
## Safety Precautions
* **Use the Correct Alcohol Concentration:** Ensure you use the recommended alcohol concentration (at least 60% ethanol or 70% isopropanol) to ensure the hand sanitizer is effective at killing germs.
* **Avoid Methanol:** Do not use methanol (methyl alcohol), as it is toxic and can cause serious health problems.
* **Flammability:** Alcohol is flammable. Keep the hand sanitizer away from open flames and heat sources.
* **Eye Contact:** Avoid getting the hand sanitizer in your eyes. If contact occurs, rinse thoroughly with water.
