Knapp Essentials is a company dedicated to providing our customers with high quality, clean-burning soy wax candles made with essential oils or non-toxic fragrance oils. The fragrance oils used in our candles differ from many traditional candles as they do not contain phthalates, carcinogens, mutagens, endocrine disruptors, or other known toxins. We also use only 100% all-natural soy wax from U.S grown soy beans, as well as cotton core wicks.
