Dangers of Excessive Fragrance in Candles
Adding too much fragrance to candles can result in the candle burning unevenly, producing a weak scent or none at all, and potentially causing irritation or allergic reactions. It can also lead to the wax becoming overheated and melting, which is a fire hazard.
Excess fragrance changes wax composition, leading to a softer consistency, not hardening correctly. It also increases fire risk as the fragrance oil heats and ignites more easily. Too much fragrance causes excessive smoke, soot, and unstable, frothy wax.
As the oil and wax mixture cools, excess fragrance oil seeps to the top of the candle, causing seeping or leaching which looks like bubbles and is flammable, leading to a weak scent. Too much fragrance affects candle appearance and fire risk without contributing to fragrance. It impacts many aspects of the candle.
Fragrance Load Recommendations
How much fragrance oil should be added to candles? The amount depends on the type of wax. Generally, add 10% fragrance oil per kilogram of wax. More fragrance can lead to a candle burning unevenly, producing weak scent, irritation, allergic reactions, overheated wax, and fire hazard.
Summary
While some fragrance is essential for scent, too much compromises safety and appearance without strengthening smell. It impacts many aspects of the candle negatively. The goal is to use enough fragrance for scent without causing issues.
