P-MENTHANE-3,8-DIOL

Scientific Protection Mechanism: A Recognized Natural Mosquito Repellent

P-Menthane-3,8-diol (PMD) is a widely recognized effective natural mosquito repellent derived from oil of lemon eucalyptus. The primary function of mosquito repellents is not to kill mosquitoes, but to provide protection by repelling them.

PMD works by interfering with mosquitoes’ olfactory system, preventing them from accurately detecting and locating their “targets.” Currently, the most effective mosquito repellent active ingredients include the chemical compounds DEET and picaridin. Among natural alternatives, PMD extracted from lemon eucalyptus oil is the only one that is broadly acknowledged for its proven efficacy.

Key Benefits


As a naturally derived mosquito repellent ingredient, PMD offers a unique competitive advantage in the market. Compared with synthetic chemical compounds, its natural origin combined with well-established scientific evidence makes PMD a preferred choice among consumers.

One of the Three Main Active Ingredients

PMD ranks alongside DEET and Picaridin as one of the currently recognized effective mosquito-repelling active ingredients.

Naturally Derived Extract

Refined from lemon eucalyptus oil, PMD offers a high-quality natural alternative to synthetic chemical compounds.。

Superior Repellent Performance

Effectively disrupts mosquitoes’ sensory system, preventing them from accurately detecting human scents.

※ Among recognized effective natural ingredients, PMD provides consistent and long-lasting protection.

Protection Timeline


The duration of protection provided by PMD is proportional to its concentration. The table below, based on experimental data, compares the optimal protection times of PMD and other common active ingredients at different concentrations:
Active Ingredient 1 ~ 2 hr 2 ~ 4 hr 4 ~ 6 hr 6 ~ 8 hr
PMD  10 ~ 20% 20 ~ 30% -- --
DEET -- 10 ~ 20% 20 ~ 30% 30 ~ 50%
Picaridin -- -- 10 ~ 15% 15 ~ 25%
IR3535 10 ~ 20% 20 ~ 30% -- --

Applications


Thanks to its natural origin and well-established scientific evidence, PMD is widely used in the following products:
  • Natural Mosquito Repellents: High-efficiency natural sprays or lotions for consumers seeking non-synthetic ingredients.

  • Family-Friendly Protection Series: Skin-friendly products suitable for adults and older children, leveraging its recognized natural safety.

  • Functional Outdoor Sprays: High-concentration formulations (20–30%) providing 2–4 hours of outdoor repellent effectiveness.
