If you're interested in making candles by yourself, the first step is to understand what candles are made of. Essentially, candles are solid fuels that burn to produce light and fragrance, and their core components are various types of wax. The three main types of wax used in candle making are paraffin, beeswax, and vegetable wax, with paraffin being the most commonly used in both industrial and home candle production.
📒 Paraffin wax is a by-product of petroleum refining and is composed primarily of long-chain alkanes. It is odorless, white or colorless, and burns cleanly when properly formulated. Paraffin is widely favored for its affordability, ease of coloring and scenting, and its ability to hold shape well in molded candles.
📒 Beeswax, on the other hand, is a natural substance produced by honeybees, specifically secreted from glands of worker bees, not the queen bee. Its chemical composition includes various ester compounds such as beeswax acid, beeswax alcohol, and beeswax aldehyde. Beeswax has a pleasant natural honey scent, burns longer and cleaner than paraffin, and has been used for centuries in traditional candle making.
📒 Vegetable wax is plant-based and includes types like soy wax, palm wax, and helichrysum wax. These waxes are derived from renewable resources, making them more environmentally friendly. For example, soy wax, extracted from soybean oil, is biodegradable, has a lower melting point, and offers excellent fragrance-holding ability, making it ideal for container candles.
In addition to the main waxes, candle making also involves auxiliary materials like pigments and fragrances. Pigments are used to give candles their color, with common options including carbon black for dark tones, titanium dioxide for whites, and iron oxides for earthy shades. Fragrances are added to provide a pleasant scent when the candle burns-popular choices include natural and synthetic aromas like lavender, orange blossom, vanilla, and jasmine.
In summary, candle raw materials include a base wax-paraffin, beeswax, or vegetable wax-along with colorants and scent additives. Each type of wax has its unique properties, and the choice and proportion of these materials greatly affect the candle's burn time, scent throw, appearance, and environmental impact.
