Bug Repellents & Bug Relief Products: A Scientific & Regulatory Guide for Cosmetic Formulators

Developing insect repellents and bug relief products is far more complex than simply choosing the right ingredients.

Understanding these regulatory boundaries is essential before investing time and money into formulation, branding and marketing.

This comprehensive educational guide has been written specifically for cosmetic formulators, indie brands, product developers and regulatory professionals who want to understand the science and legislation governing insect repellents and bug relief products in Australia, the United States and the European Union.
