Make Hand Sanitizer Gel using HPMC to replace of Carbomer

Making hand sanitizer gel using Hydroxypropyl Methylcellulose (HPMC) as a replacement for Carbomer is feasible. Carbomer is a common thickening agent used in hand sanitizer gels to provide viscosity and improve consistency. However, HPMC can serve as an alternative thickener with similar functionality. Here’s a basic recipe for making hand sanitizer gel using HPMC:

Ingredients:

• Isopropyl alcohol (99% or higher): 2/3 cup (160 milliliters)
• Aloe vera gel: 1/3 cup (80 milliliters)
• Hydroxypropyl Methylcellulose (HPMC): 1/4 teaspoon (about 1 gram)
• Essential oil (e.g., tea tree oil, lavender oil) for fragrance (optional)
• Distilled water (if needed to adjust consistency)

Equipment:

• Mixing bowl
• Whisk or spoon
• Measuring cups and spoons
• Pump or squeeze bottles for storage

Instructions:

1. Prepare Work Area: Ensure your workspace is clean and sanitized before beginning.
2. Combine Ingredients: In a mixing bowl, combine the isopropyl alcohol and aloe vera gel. Mix well until they are thoroughly combined.
3. Add HPMC: Sprinkle the HPMC over the alcohol-aloe vera mixture while stirring continuously to prevent clumping. Continue stirring until the HPMC is fully dispersed and the mixture begins to thicken.
4. Mix Thoroughly: Whisk or stir the mixture vigorously for several minutes to ensure the HPMC is fully dissolved and the gel is smooth and homogeneous.
5. Adjust Consistency (if necessary): If the gel is too thick, you can add a small amount of distilled water to achieve the desired consistency. Add water gradually while stirring until you reach the desired thickness.
6. Add Essential Oil (optional): If desired, add a few drops of essential oil for fragrance. Stir well to distribute the fragrance evenly throughout the gel.
7. Transfer to Bottles: Once the hand sanitizer gel is well-mixed and has reached the desired consistency, carefully transfer it to pump or squeeze bottles for storage and dispensing.
8. Label and Store: Label the bottles with the date and contents, and store them in a cool, dry place away from direct sunlight.

Notes:

• Ensure that the final concentration of isopropyl alcohol in the hand sanitizer gel is at least 60% to effectively kill germs and bacteria.
• HPMC may take some time to fully hydrate and thicken the gel, so be patient and continue stirring until the desired consistency is achieved.
• Test the consistency and texture of the gel before transferring it to bottles to ensure it meets your preferences.
• It’s essential to maintain proper hygiene practices and follow guidelines for hand hygiene, including using hand sanitizer gel effectively and washing hands with soap and water when necessary.
