Production
The first thing to consider when choosing between dry and liquid flavoring is, of course, the efforts and resources required to produce them. ;
Dry beverage flavors are most commonly produced by dry spraying, in which a mix of the desired flavor, water, and a carrier are atomized into hot air. At that point, the mixture cools quickly, trapping the desired flavors into their final powdered form. ;
Liquid flavors are a little more straightforward: you mix your desired flavors with your preferred carrier (and this varies depending on whether you are looking to produce water-soluble flavors, alcohol extracts, fruit flavors, etc.) instead of going through the dry spraying process. ;
Ultimately, liquid flavors are a simpler process, as dry spraying involves more steps and equipment. ;
ELEMENTS OF A CANDLE: FRAGRANCE
The addition of fragrance to a candle formulation is a common practice in the United States. In fact, an estimated 75 to 80 percent of candles sold in the U.S. are scented. Candle fragrance manufacturers work closely with fragrance companies to develop candle fragrances that are not only pleasing but will burn safely and properly.
The aroma from a lighted scented candle is released through the evaporation of the fragrance from the hot wax pool and from the solid candle itself. Like unscented candles, properly-formulated scented candles will primarily produce water vapor and carbon dioxide when burned. The only difference is that a fragrance is also released with a scented candle.
Most scented candles contain a combination of natural and synthetic fragrances These fragrance materials may be derived from essential oils or from synthetic aroma chemicals. A well-made candle will contain only fragrance materials approved for candle use; the addition of fragrance to a candle formulation should be carefully monitored to ensure that the candle will burn cleanly and properly.
Candle manufacturers can select from more than 2,000 aroma chemicals and essential oils to develop scents that are both pleasing to consumers and compatible with candle use. These fragrance materials are safe, high-quality ingredients that are also found in many perfumes, bath soaps, lotions, and shampoos.
Various health and safety tests are conducted on the raw fragrance materials that are used in candles and other consumer products. Reputable candle manufacturers use only expertly-formulated fragrances specifically approved for candle use.
Air freshener
Air freshener fragrances are consumer products that typically emit fragrance and are used in homes or commercial interiors such as restrooms, foyers, hallways, vestibules, and other smaller indoor areas, as well as larger areas such as hotel lobbies, auto dealerships, medical facilities, public areas, and other large interior spaces. Car fresheners are used in automobiles. As a source of odors, specific deodorizing blocks are made for toilets and urinals.
There are many different methods and brands of air fresheners. Some of the different types of air fresheners include electric fan air fresheners, gravity drip hygiene odor control cleaning systems, passive non-mechanical evaporating aroma diffusers, and metered aerosol time-operated mist dispensers, sprays, candles, oils, gels, beads, and plug-ins.
Some air fresheners contain chemicals that provoke allergy and asthma symptoms or are toxic. Air freshening is not only limited to modern-day sprays, air freshening also can involve the use of organic and everyday household items. Although air fresheners are primarily used for odor elimination, some people use air fresheners for the pleasant odors they emit.
