6. Glycerin
Glycerin is categorized as a humectant — a substance that brings moisture into your skin. Glycerin is a byproduct of most processes used to make soap. You’ll find it on the ingredient list of most commercial earwax drops. Glycerin is a colorless, thick, neutral liquid that is very effective as softening earwax to the point that it just drips out.
Due to the fact that it attracts liquids and lubricates anything it touches, it will ensure that any hardened earwax becomes soft enough for safe extraction. While it can be used on its own without major risk, it’s advised that you dilute it with some water to reduce the potency and make it a bit safer for home use.
Adding water will also thin the chemical out which will help it enter deeper into your ear canal to ensure that it gets earwax that is lodged further down. Don’t dilute it too much though as that will reduce its efficacy.
