Herbal Mosquito Repellang Powder

Introduction

Mosquitoes cause many diseases like Malaria and Dengue fever. A low cost process/technology has been developed for a herbal based mosquito repellant powder.

A comparison of herbal repellant with conventional chemical based repellants is given below

Contentional repellants (w/w)%
Active ingredient pyrethrins	1.6
Stabilizer	1.0
Perfume	1.0
Solvent: deodorized kerosene	96.4

Newly developed herbal powder (w/w)%
Solvent: Kerosene	89.5
Vasumbu powder	8
Neem leaf powder	1
Tulasi leaf powder	1
Turmeric powder	0.5

The powder mix is dissolved in kerosene and filled in the emptied bottles of marketed repellants. One bottle requires 35 ml of kerosene and it works for 40 days. The cost of one packet of herbal powder mix (10g) is Rs 2.50. It saves us from the chemicals that are released into our atmosphere by conventional repellants.
