What Happens When You Mix Vaseline and Coke?

Mixing Vaseline, Coke, and coconut oil can create a DIY lip balm that’s surprisingly effective for moisturizing and soothing lips. This combination doesn’t involve a dramatic chemical reaction but instead creates a mixture where each ingredient serves a purpose for your skin.

The Vaseline acts as the base, the coconut oil adds hydration and a subtle scent, and the Coke imparts a sweet flavor and slight tint.

Here’s how it works, and how you can make your own lip balm at home.

The Chemistry Behind the Mixture

When you combine Vaseline (a petroleum jelly), Coke, and coconut oil, there isn’t a chemical reaction like fizzing or bubbling. Instead, the substances mix physically, forming an emollient balm.

Vaseline’s semi-solid consistency binds the liquid components of the Coke and melted coconut oil. The Coke doesn’t dissolve the Vaseline because petroleum jelly is hydrophobic, but it blends into the mixture thanks to heat, which softens Vaseline into a malleable state.

Coconut oil adds nourishing fatty acids and vitamin E to the balm, which are great for repairing dry or cracked lips. Coke, when reduced (or lightly simmered), contributes caramelized sugar, a gentle tint, and a subtle sweet taste, making the balm more fun and appealing.

How to Make a DIY Vaseline, Coke, and Coconut Oil Lip Balm

Total Time: 10 minutes
Yield: Enough for 1 small jar of lip balm
Cuisine: Skincare DIY
Nutrition Information: N/A (for external use only!)

Supplies

  • Small saucepan or heat-safe bowl
  • Spoon or spatula
  • Heat source (stove or microwave)
  • Lip balm container (small tin or jar)
  • Measuring spoons

Ingredients

  • 2 teaspoons Vaseline (petroleum jelly)
  • 1 teaspoon coconut oil
  • 1 tablespoon Coca-Cola

Instructions

  1. Prepare the Coke Reduction:
    Pour the Coca-Cola into a small saucepan and heat it gently on low until it reduces by half, creating a syrup-like consistency. This concentrates the flavor and caramelized sugars. Let it cool slightly.
  2. Melt Vaseline and Coconut Oil:
    In a heat-safe bowl, combine the Vaseline and coconut oil. Warm the mixture in the microwave in 10-second bursts or using a double boiler until it becomes a smooth, liquid consistency.
  3. Combine Ingredients:
    Slowly stir the reduced Coke into the melted Vaseline and coconut oil. Mix well to distribute the Coke evenly throughout the balm.
  4. Pour and Cool:
    Pour the mixture into a small lip balm container. Let it cool and solidify at room temperature or place it in the fridge for faster results.
  5. Use and Enjoy:
    Once solidified, your lip balm is ready to use! Apply a small amount to your lips as needed to keep them soft and hydrated.

Why This Balm Works

  • Vaseline: Locks in moisture and provides a protective barrier against the elements.
  • Coconut Oil: Nourishes lips with essential fatty acids and a natural shine.
  • Coke: Adds a fun twist with its sweet flavor, slight tint, and appealing scent.

This DIY lip balm is not only budget-friendly but also customizable—try adding a few drops of vanilla extract or a pinch of glitter for extra flair. Keep your lips happy, hydrated, and a little sweeter!
