Hey there! As a DEET supplier, I often get asked about how DEET stacks up against IR3535. So, I thought I'd dive into this topic and share some insights based on the latest research and my own experiences in the industry.
First off, let's talk about what these two chemicals are. DEET, or N,N - Diethyl - m - toluamide, has been around for ages. It was developed by the U.S. Army in the 1940s to protect soldiers from insect - borne diseases in the tropics. Since then, it's become one of the most widely used insect repellents in the world. On the other hand, IR3535, also known as 3 - (N - Butyl - N - acetyl) aminopropionic acid ethyl ester, is a newer player on the scene. It was developed in the 1980s and has gained popularity as a more "natural - feeling" alternative to DEET.
When it comes to effectiveness, the big question is: which one repels insects better? Well, numerous studies have shown that DEET is generally more effective than IR3535 in terms of the duration of protection. DEET can provide protection against mosquitoes, ticks, and other biting insects for several hours, depending on the concentration. For example, a 20% DEET formulation can protect you for about 3 - 5 hours, while a 30% formulation can last up to 6 - 8 hours.
IR3535, however, typically offers a shorter duration of protection. A standard 20% IR3535 product may only protect you for 1 - 2 hours. This difference in effectiveness is mainly due to how these chemicals work. DEET works by interfering with the insects' olfactory receptors, making it difficult for them to detect the carbon dioxide and other chemicals that humans emit. This confusion makes it less likely for insects to land on and bite you.
IR3535, on the other hand, seems to work more as a masking agent. It covers up the scents that attract insects, but its effect is not as long - lasting or as strong as DEET. In areas with a high density of mosquitoes or other biting insects, DEET is often the better choice to ensure you're well - protected.


Another aspect to consider is the spectrum of insects repelled. DEET is known to be effective against a wide range of insects, including mosquitoes, ticks, fleas, chiggers, and biting flies. It's been used in many different environments, from tropical rainforests to suburban backyards. IR3535 is also effective against mosquitoes, but its effectiveness against other insects like ticks and fleas is not as well - established.
Now, let's talk about safety. Both DEET and IR3535 are considered safe when used as directed. However, there have been some concerns about DEET in the past. Some people have reported skin irritation, especially when using high - concentration DEET products. There have also been rare cases of neurological effects in children, but these are extremely rare and usually occur when DEET is misused, such as ingesting it or using it in large amounts.
IR3535 is often touted as a safer alternative because it has a milder smell and is less likely to cause skin irritation. It's also biodegradable, which is a plus for the environment. But again, it's important to use any insect repellent according to the instructions to minimize any potential risks.
In terms of cost, DEET is generally more cost - effective. Since it provides longer - lasting protection, you don't need to re - apply it as often as IR3535. This means you can get more protection for your money in the long run.
As a DEET supplier, I've seen firsthand the demand for this product. Many consumers, especially those who spend a lot of time outdoors, prefer DEET because of its proven effectiveness. Whether you're going on a camping trip, hiking in the woods, or just spending an evening in your backyard, DEET can give you the peace of mind that you're protected from insect bites.
