Candles enjoyed renewed popularity during the first half of the 20th century, when the growth of U.S. oil and meatpacking industries brought an increase in the byproducts that had become the basic ingredients of candles – paraffin and stearic acid.
The popularity of candles remained steady until the mid-1980s, when interest in candles as decorative items, mood-setters and gifts began to increase notably. Candles were suddenly available in a broad array of sizes, shapes and colors, and consumer interest in scented candles began to escalate.
The 1990s witnessed an unprecedented surge in the popularity of candles, and for the first time in more than a century, new types of candle waxes were being developed. In the U.S., agricultural chemists began to develop soybean wax, a softer and slower burning wax than paraffin. On the other side of the globe, efforts were underway to develop palm wax for use in candles.
