Are synthetic fragrances harmful?  

Are synthetic fragrances bad for my health? What's the difference between a natural and synthetic fragrance? How do I know if a fragrance is truly natural?
When made from plant-based ingredients such as herbs, flowers, spices, and essential oils, fragrances don’t just make you smell good—they can make you feel good, too. 

Most conventional sweet- smelling ingredients today are synthetic.  Fragrances can contain any number of 400 natural or synthetic ingredients, many of which are derived from petrochemicals. 

The problem with fragrances

Fragrances are among the top five known allergens in North America and Europe. More than 100 fragrance ingredients can cause itchy, scaly, painful skin, and potentially worsen asthma, and synthetics aren’t the only ingredients known to trigger allergic reactions. Even high concentrations of certain natural ingredients including tea tree, lavender, and citrus peel oils may cause such symptoms.

The rise of nontoxic scents

Thanks to greater awareness about the potential risks of synthetic ingredients, perfumers are finding success with natural formulations. Essential oils, often used in natural fragrances, have a range of mind-body benefits

The beauty of natural perfumes

When you buy natural fragrances—or beauty products containing them—you also support farmers and harvesters of plant-based ingredients. 


I am making some reed diffusers fragranced with essential oils, I am having trouble making the fragrance strong enough and finding the right carrier Liquid. Does anyone have a good recipe?

The fragrance base Ingredients: DPG, IGEPAL CO 730, TERGITOL NP9, TRITON X-100. This is pretty typical for a fragrance oil base.

Courtesy of wikipedia Dipropylene glycol is a mixture of three isomeric chemical compounds, 4-oxa-2,6-heptandiol, 2-(2-Hydroxy-propoxy)-propan-1-ol, and 2-(2-Hydroxy-1-methyl-ethoxy)-propan-1-ol. It is a colorless, nearly odorless liquid with a high boiling point and low toxicity. 

DPG is used to make perfume, incense and other products. I have seen that a 1:1 ratio is recommended for making fragrance oil, a 3 (parts fragrance oil) to 7 (parts DPG) for making reed diffusers, and a 1 (fragrance) to 3 (DPG) ratio for making perfume oil. 

OK I am going to stick my neck out here. All those volatile hydrocarbons are very very light. Inhaling them is going to add a microscopic load to the liver. When I fill my car with petrol I probably get a heftier dose of harmful hydrocarbons than I ever would inhaling DPG as a room fragrancer. Its not going to kill you or your clients.

However it is synthetic and for those of us who believe (in an intuitive and unproven way) there is some physics besides the basic chemistry that makes essential oils special thats enough to kill the vitality to be conveyed by the fragrance which is why we advocate diffusion by a fan of air or electrically heated stone.
