Zevo On-Body spray uses IR3535 at 20% as the active ingredient; the rest are inert carriers and skin conditioners.
Shopping for a repellent and wondering what’s actually inside the bottle? You’re not alone. Below is a plain-language breakdown of the ingredients in Zevo On-Body mosquito and tick repellent, how the label works, and what “other ingredients” means in practice. You’ll see what’s disclosed, what isn’t listed by name, and why that’s common across EPA-registered repellents. Zevo’s own pages emphasize a single active, while the federal label record confirms the concentration, so you can be confident about what’s doing the bite-blocking work.
Ingredients In Zevo On-Body Spray — Label Facts & Safety
The short version: the active ingredient in Zevo On-Body is IR3535 (ethyl butylacetylaminopropionate) at 20% of the formula. Everything else on the label is grouped under “other ingredients” (80%). This is standard for U.S. skin-applied repellents; EPA reviews the whole formula for safety and effectiveness, but only requires that the active be named on the front panel.
What The Active Ingredient Does
IR3535 is an EPA-approved repellent active used on human skin. It helps keep mosquitoes and ticks away and has a long safety record when used as directed. Zevo advertises up to 8 hours of protection with its On-Body line, which aligns with how IR3535 products are typically positioned.
What “Other Ingredients” Usually Include
“Other ingredients” is a catch-all term for everything that isn’t the active. In a repellent spray or lotion, that often means solvents or water, emollients to keep skin comfortable, film-formers that help the active stay put, neutralizers for feel, and (for aerosols) a propellant. These inerts are vetted during EPA registration, even if each one isn’t listed by name on the consumer label.
Zevo On-Body: Ingredient Roles At A Glance
This table summarizes what’s inside Zevo On-Body by function. The exact inactive chemicals may vary across the pump, aerosol, and lotion formats, but the roles stay consistent and the active stays the same.
| Component Or Class | What It Does | Listed On Label? |
|---|---|---|
| IR3535 (20%) | Repels mosquitoes and ticks on skin | Yes (named active) |
| Solvent System | Helps dissolve and spread the active evenly | No (part of “other ingredients”) |
| Water | Balances feel and delivery on skin | No (grouped with inerts) |
| Emollients | Add slip and comfort; reduce dryness | No (grouped with inerts) |
| Film-Former | Helps the active stay on skin longer | No (grouped with inerts) |
| Neutralizers/Adjusters | Tune pH and feel for skin comfort | No (grouped with inerts) |
| Propellant (Aerosol Only) | Pushes the product out as a fine spray | No (grouped with inerts) |
| Preservative System | Protects product quality over shelf life | No (grouped with inerts) |
How The Zevo On-Body Label Is Structured
On a registered repellent, you’ll see the active named with its percentage and the balance listed as “other ingredients.” For Zevo On-Body, the federal record lists IR3535 at 20% under EPA Reg. No. 70759-3. If you’re checking a package in a store or online, look for that percentage on the back panel; Zevo’s product page also states the single active.
Why Brands Don’t List Every Inactive By Name
EPA evaluates all inerts for the finished formula, but doesn’t require a public list of each one. That protects trade dress while still enforcing safety. If you have a confirmed allergy and need the full list for medical reasons, contact the manufacturer; companies can often share more detail through customer care.
What Are The Ingredients In Zevo On-Body Spray? (Straight Answer)
Here’s the straight answer in one place, using the exact label language:
- Active: IR3535 (ethyl butylacetylaminopropionate) — 20%.
- Other Ingredients: 80% — carriers and care ingredients that deliver the active on skin; names are not listed on the retail label.
Zevo markets the entire On-Body line (aerosol, pump, lotion) with the same active and an “odorless, not sticky” feel that’s designed for everyday use up to 8 hours.
IR3535: What It Is And Why It’s Used
IR3535 is a skin-applied repellent active inspired by an amino acid. It’s been on the market for decades, is registered by EPA, and can be used on exposed skin to help prevent bites from mosquitoes and ticks when used as directed. The EPA biopesticide fact sheet describes its use profile and safety evaluation.
Protection Time And Use
Zevo advertises up to eight hours of protection with On-Body. Apply to clean, dry, exposed skin, and reapply as directed on the label if you sweat heavily, swim, or towel off. Keep sprays away from eyes by spraying into hands first for the face, which matches the brand’s usage tips.
Where Zevo Fits Among Repellent Options
Consumers often compare IR3535 products to DEET, picaridin, and oil of lemon eucalyptus. Each has strengths. EPA maintains plain-language pages that describe how skin-applied repellents are reviewed and which active ingredients are allowed in registered products. If you’re choosing for a trip or a season, start with actives and duration rather than brand alone.
Common Repellent Actives At A Glance
| Active | EPA Status | Typical Protection Window* |
|---|---|---|
| IR3535 | EPA-registered for skin use | Up to ~8 hours (product-dependent) |
| DEET | EPA-registered for skin use | ~6–10 hours at higher % |
| Picaridin | EPA-registered for skin use | ~6–8 hours at typical % |
| Oil Of Lemon Eucalyptus (PMD) | EPA-registered for skin use | ~6 hours at labeled % |
*Windows vary by brand, concentration, format, and test method. See EPA’s overview of skin-applied repellent ingredients and check each product’s label.
Format Differences: Pump, Aerosol, And Lotion
Zevo On-Body comes in pump, aerosol, and lotion. All list IR3535 as the active. The feel and delivery change with format. The aerosol uses a propellant to create a fast, even mist; the pump gives controlled placement; the lotion offers hands-on coverage with a hydrating base. If you prefer a precise application for kids’ arms and legs, the pump or lotion is handy. For quick full-limb coverage, the aerosol is convenient.
How To Read And Use The Zevo Label
Find The Active And Percentage
Look for IR3535 — 20% near the ingredient box and the EPA registration number (70759-3). That percentage is what matters for protection time in a given format.
Follow The Use Directions
Apply to exposed skin only. Spray into hands to apply to the face. Don’t use on cuts or irritated skin. Wash hands after use. Keep out of reach of children when not in use. These are standard directions on Zevo’s pages and align with best practices for any skin-applied repellent.
Have Sensitivities Or Allergies?
If you must avoid a specific inactive, contact Zevo’s consumer care line and request the full list for your package lot. EPA’s process covers the safety of the finished formula, but brand support can help with personal medical needs.
Why “One Active” Matters For Shoppers
Zevo highlights that On-Body uses only one active. That makes comparing across shelves easier: check the active and its percentage first. If you already like how IR3535 feels on your skin, staying within that active can keep your routine simple. Zevo’s product page leans into that straightforward story.
Trusted Sources You Can Check
Want to verify the ingredient and concentration? Two solid places to look are the Zevo On-Body product page and the EPA’s public label listing for IR3535 20% spray. You can also read EPA’s overview of how skin-applied repellents are reviewed and registered.
Bottom Line
The ingredient story for Zevo On-Body is simple: IR3535 at 20% is the active that repels, and the rest of the formula supports feel, spread, and stability. If you want a DEET-free option with an EPA-reviewed active and an easy feel on skin, Zevo’s On-Body formats fit that brief. For the most accurate snapshot, read the back panel for the 20% listing and use the product as directed.
