Before you put something new on your face, it makes sense to read what is in it. "NasalGuard ingredients" is one of the questions people search most about the gel, so here is the answer in one place.
Below is the full list, followed by a short, everyday explanation of what each group of ingredients is there for. No lab vocabulary required.
What NasalGuard is
NasalGuard® Airborne Particle Blocker is an invisible, drug-free gel applied around the outside of the nostrils and above the upper lip to help reduce inhalation of everyday airborne particles such as pollen, dust, and pet dander. It uses positive ion technology to create an invisible gel barrier around the outside of the nostrils.
It is a topical gel. It is not a medicine or a drug, and it is not intended to be inserted into the nose. For a longer look at how the barrier works, see Does NasalGuard Work?
The full NasalGuard ingredients list
Here are the NasalGuard ingredients for NasalGuard Airborne Particle Blocker:
Purified Water, Hydroxyethylcellulose, Potassium Sorbate, Glycerin, Benzalkonium Chloride, Phenoxyethanol, Caprylic/Capric Triglyceride, Steareth-2, Dimethicone, Menthol, Fragrance.
Menthol and fragrance are in the Cool Menthol versions. The Unscented versions leave them out.

What the ingredients do, in everyday words
Eleven names can look like a lot. They fall into four simple groups.
A water-and-gel base
Purified water, hydroxyethylcellulose, and glycerin make up the base. Together they give NasalGuard its soft gel texture, so a small amount stays where you put it.
A smooth, even feel
Caprylic/capric triglyceride, steareth-2, and dimethicone help the gel spread smoothly between your thumb and finger and go on in a thin, even layer.
Preservatives
Potassium sorbate, benzalkonium chloride, and phenoxyethanol are preservatives. Their job is to keep the gel in good condition from the first use to the last.
Menthol and fragrance, in Cool Menthol only
Menthol and fragrance give the Cool Menthol versions their fresh, cool scent. If you would rather have nothing to smell, choose Unscented.
Unscented vs Cool Menthol
The difference between the two scents comes down to those last two ingredients. Both versions use the same invisible gel barrier, applied the same way. Pick the one you like wearing.
- Unscented suits people who prefer no scent near their nose, or who wear it at a desk or around other people. Try NasalGuard Airborne Particle Blocker, Unscented.
- Cool Menthol suits people who like a fresh, cool scent when they apply it. Try NasalGuard Airborne Particle Blocker, Cool Menthol.
Both scents also come in the For Air Travelers line, sized for a carry-on, and in a larger 10g size. You can see every version on the all products page.

What the gel looks like, and how to apply it
Straight from the tube, NasalGuard is an opaque, milky-white gel. Once you spread it into a thin layer, it goes on invisibly.
To apply: place a small amount on a fingertip, spread it between the thumb and finger, and apply around the outside of the nostrils and above the upper lip. Reapply according to the current directions and after the area becomes wet. Check the label of your exact version for directions and how much to use.
