What's in a Fragrance Oil?

Not all fragrance oils are created equal, but CandleScience has gathered some of the very best into a line that's extensively tested and rated for performance in soy wax. This rating indicates which fragrances throw well in soy so you won't waste money on fragrance oils that are incompatible with soy wax. These ratings also transfer well to palm waxes and are excellent in all of our paraffin waxes. Testing for new fragrances is an ongoing process, and new fragrances are added regularly.

CandleScience fragrances are a combination of natural essential oils and synthetic aroma chemicals. They are never diluted, so each has a strong concentrated aroma that doesn't disappear when burned in a candle.

Essential oils

Essential oils are pure liquids containing aroma compounds that are removed from the seeds, flowers, leaves, roots, and stems or bark of plants through methods such as distillation, expression or extraction. These oils carry the distinctive essence, or scent, of the plant it was made from and are frequently used in perfumes, flavorings and medicines. The only way to scent candles naturally is with pure essential oils. We are currently testing to determine whether we can offer a high quality line of essential oil fragrances that work well in our natural soy and palm waxes.

Aroma Chemicals

Because essential oils are not available for every scent we'd like to use, we draw on synthetic aroma chemicals which come in powder or liquid form. We use these concentrated compounds when no essential oil is available - like in Chocolate Fudge or Blueberry Cheesecake fragrances.

Solvents and Diluents

Solvents are dissolving agents. Diluents are diluting substances.

When a synthetic aroma chemical is in powder form, a solvent is required to convert it to a liquid for use in fragrance oil. Solvents can help the components of a fragrance burn more easily, blend better, improve fragrance throw and increase fragrance longevity.

If an essential oil is in a highly concentrated form, a diluent is required to thin it so that it will remain suspended in the liquid fragrance oil. This substance adjusts the density of fragrance oils so that it's easier for the wax/fragrance mixture to be pulled up through the wick to be burned at the flame.

Some diluents are used to "cut" fragrance oils after they are produced so that an expensive fragrance oil can be sold at a lower price with a weaker strength. Once Candlescience fragrances are developed, they are NEVER diluted or "cut" in any way.

The Cost of Fragrance Oils

Because of the variety of essential oils and synthetic aroma chemicals used to produce the quality fragrance oils in our CandleScience line, the cost of each will vary. When a fragrance has several essential oils or contains distinctive aroma chemicals, the cost will be higher. Since the price of a scent is determined by its components, some of the more unique complex fragrances are more expensive to develop. CandleScience is very particular about the quality of fragrances in the line, so there are no poor performing fragrance oils.

Most of the fragrance oils are infused with essential oils and are listed on each fragrance page. The components of our fragrance oil blends are proprietary information, but when we can share those, we do.

Phthalates

Many of our oils are Phthalate free which is stated in the detail section of the fragrance page. We are not adding any new oils to the website that contain Phthalates.

We do have some older fragrances that contain Phthalates and are currently reformulating them. As soon as they are Phthalate free we will state this on the website.

We adhere to the strict RIFM (Research Institute for Fragrance Materials) standard regarding fragrance safety. Our products are non-toxic when used for their intended purpose in candle making.
