When it comes to protecting our kids from insect bites, especially in warmer months or while traveling, insect repellents are a must. But not all repellents are created equal—and some can do more harm than good. Many conventional insect repellents contain DEET, Picaridin, or IR3535—powerful synthetic chemicals that raise safety concerns, especially for young children.
Fortunately, natural alternatives like THEYE's PMD-based insect repellent range offer safe, effective protection—even for babies as young as 6 months old.
In this blog, we’ll explore:
-
The health risks of DEET, Picaridin, and IR3535 for children
-
Why natural, plant-based alternatives like PMD are gaining popularity
-
How THEYE insect repellents provide peace of mind for parents
What Are DEET, Picaridin, and IR3535—And Why Are They Controversial?
These three ingredients are commonly found in many insect repellents. While effective at keeping mosquitoes, ticks, and midges at bay, they come with a range of potential health concerns—especially for children with delicate skin and developing immune systems.
🧪 1. DEET (N,N-Diethyl-meta-toluamide)
Used since the 1950s, DEET is well known for its ability to repel insects for long periods. However, it’s also known for its harshness on skin and possible toxic effects.
Risks of DEET for Children:
-
Can cause skin irritation, redness, and rashes
-
Linked to neurological effects in rare cases (e.g. seizures)
-
Not recommended for children under 12 years (some products even say 18 years+)
-
Potential eye and mucous membrane irritation
-
Strong chemical smell and can damage plastics or synthetic materials
🧪 2. Picaridin (also known as Icaridin)
Picaridin is a synthetic compound developed as a safer alternative to DEET. While it’s less greasy and odourless, studies suggest it's not entirely risk-free.
Side Effects of Picaridin:
-
Eye and skin irritation, especially if used in higher concentrations
-
Toxic to aquatic life, raising environmental concerns
-
Not suitable for children under 2 years
-
May cause allergic reactions or dermatitis in sensitive individuals
While generally considered safer than DEET, Picaridin is still a synthetic chemical, and long-term use on children is not well studied.
🧪 3. IR3535 (Ethyl butylacetylaminopropionate)
Marketed as gentle and “bioidentical”, IR3535 is another chemical option found in repellents aimed at families but don't be fooled, it also has drawbacks.
Side Effects of IR3535:
-
Can cause eye irritation—classified as a severe irritant by the EPA
-
May cause skin sensitivity or allergic reactions
-
Not recommended for infants under 2 years
-
Breaks down in sunlight, so may need more frequent reapplication
Though IR3535 is often labeled as mild, it’s still not a natural product and lacks the safety track record of truly plant-based alternatives.
Why Natural PMD-Based Repellents Are the Safer Alternative
PMD (p-menthane-3,8-diol) is a natural compound derived from Java Citronella oil and has been clinically proven to repel mosquitoes, ticks, and other biting insects—without the toxicity risks of chemical alternatives.
PMD Benefits for Children:
-
As effective as DEET & other synthetic chemicals, without harsh side effects
-
Safe for babies 6 months and older
-
Gentle on skin—great for children with eczema or allergies
-
Non-toxic, biodegradable, and eco-friendly
