This Liposome-based repllent is the newest advancement in insect repellent technology. Similar to the earlier generation of polymer-based controlled release systems, the Liposome envelops the active ingredient, DEET, and slowly time-releases it as needed. thereby extending the effectiveness of the repellent. Unlike polymers however, liposomes are a natural compound which is more comfortable to the skin and easier to wear. Comfortable, trusted protection, in the backcountry or in the backyard.
- The Liposome base enables the 30% DEET lotion to be non-greasy, with little to no odor

- The 3 oz. size is airline approved, perfect for international travel
- Always use as directed
- [SP533]- 3 oz.

Should I use a lotion or spray repellent?
Because of the way they slow down the evaporation of the DEET, lotions always last considerably longer than sprays of comparable DEET concentrations. Sprays have the advantage of being able to be applied to clothing. Sprays remain effective much longer on clothing than on skin. Since repellents work as a 3″ barrier, clothing applications can often protect 6″ of exposed skin and significantly reduce your usage on skin. Our recommendation: DEET lotion on skin and Permethrin spray on clothing.
Can I wear a repellent with sunscreen?
Yes, but with some effects. Repellents are designed to create a vapor barrier above the skin. Good sunscreens are designed to work below the skin. Wearing both usually compromises both functions especially when sprays are used. A Controlled Release Insect Repellent lotion is the most compatible topical repellent for a sunscreen.
Our recommendation is that if you need both types of protection, first apply Stay-Put® by Sawyer a bonding base sunscreen. After 10 minutes, apply Sawyer Controlled Release Insect Repellent Lotion or a composite repellent lotion. The bonded sunscreen is less susceptible to the solvents contained in the repellent, including sprays if you use them. The Sawyer Controlled Release Insect Repellent Lotion or a composite repellent in lotion form is more compatible with the sunscreen than a spray and requires less reapplication for maximum protection of both needs.
Does DEET protect against flies?
Some yes, but mostly no. If flies are going to be an issue we recommend using the Sawyer Fisherman’s Formula which is a 20% Picaridin Spray formula. Picaridin is much more effective against flies than DEET, especially at 20% which is higher than other Picaridin formulas available on the market.
Why was I told to “get at least 30% DEET” for malaria mosquitoes?
The reason you were told to “get something with at least 30% DEET” is because under older guidelines this was true. Simply put, the higher the percentage of DEET in a given formula, the longer and more effective the protection from insects. Until the introduction of Sawyer Controlled Release Insect Repellent, we would have recommended Sawyer Maxi-DEET® 100% DEET Insect Repellent for the skin. People often confuse concentration with dosage. Lower “dosages” of 100% DEET or DEET mixed in a Controlled Release lotion or even a standard lotion work better than alcohol-based sprays.
As an added measure, you may still consider 100% DEET for times of extreme bug density. However, the real question is not how much DEET you start out with, but how much of the active ingredient, DEET, is available at any given time (even hours later) to repel those nasty mosquitoes.
Skin repellent with Slow Release Technology–Sawyer Controlled Release 20% DEET Insect Repellent uses sub-micron encapsulation to entrap the DEET. An effective and long lasting insect repellent for use on the skin is a slow release technology that keeps the repellent on the surface of the skin much longer than other formulas. This provides for slower absorption and extended effectiveness against biting insects. The Sawyer Controlled Release Insect Repellent formula provides this type of technology in a formula that is both effective and very comfortable to use.
Will DEET ruin my clothes or equipment?
Quite possibly. DEET should not damage cotton, wool, or nylon. Do not apply to or near acetate, rayon, spandex or other synthetics, furniture, plastic, watch crystals, leather and painted or varnished surfaces including automobiles.
Be sure to read the labels, and if in doubt try a sample on an obscure surface area and check it after 24 hours of exposure to DEET.
