Allergenic oxidizing fragrance contents
“The oxidizing fragrances in everything from toothpaste to shampoos and deodorants. These fragrances contents may not all be allergenic themselves but can quickly become so when they oxidize. When they are broken down by oxygen in the air to form hydroperoxides that are highly allergenic substances. Nobody knows today how many people in the population who are allergic to the oxidized fragrances because they are not included in the allergy tests done.
Researchers have now discovered that the allergenic substances may have formed already when the oils and fragrances from the supplier. When they are broken down by oxygen in the air to form hydroperoxides that are highly allergenic substances. International studies of eczema patients have shown that five to seven percent of the patients are allergic to the oxidized fragrances.
At the Department of Chemistry and Molecular Biology at Gothenburg University, have developed a new analytical method that makes it actually possible to investigate hydroperoxides in various consumer products.
– Using mass spectrometry strikes disrupting substances so that they are small fragments and it is the first time that there is a method to find these individual-specific hydroperoxides in small quantities and in complex mixtures, explains Johanna Rudbäck, a doctoral student at the University of Gothenburg.
dr. Johanna Rudbäck has defended her thesis “Allergenic Oxidation Products from Fragrance Terpenes. Chemical Analysis and Determination of Sensitizing Potency “.
This is really important. Now, manufacturers can not sit back and say that the problem does not exist. So far, the perfume industry used a 1800-century approach when examining this type of oxidation products and then find they can not find these little difficult certain substances. Now the industry must deal with the problem in an entirely different way.
Ann-Therese Karlberg explains that it only takes small amounts of hydroperoxides to trigger allergy and eczema in a person who has become allergic to them.
Previously, scientists believed that it would take a long time before fragrances change of air. But when the research team used the new method to analyze the essential oils of lavender and orange peel, they discovered that it went faster than expected.
– We saw that it formed hydroperoxides already when we got the oils from the supplier. This was surprising to us, says Johanna Rudbäck.”

“Spa personnel who works with essential oils in high consentrations is a rather new profession found hurt by handeling the oils. During some years back the skin clinic at Sahlgrenska hospitals have received several patients in the profession of masseuses from several parts of Gothenburg, Skövde and Varberg.
– The read thread here is that they have worked with essential oils smelling of for example lavender, roses or citrus, says Lina Hagwall who is researcher and expert on these substances. When the occupational dermatologic clinic tested the essential oils on several of the patients they could confirm that is was the oxidizing fragrance in the oils they were allergic to.
How can you, in your marketing say that your aromatherapy oil is healing and protective to the skin when you know that there are masseuses who have suffered from allergy and eczema of your oil?”
“Sanna Gunnesson, Mia Senor and Nina Sellman that all three worked at Hagabadet Spa in Gothenburg, where they massaged customers with organic oils from Kerstin Florian Aromatherapy series, and then got allergic reactions, says that it felt immoral to sell oil to customers. – I can not do it. I can not stand and lie to a customer that way. It feels wrong to sell a product when you have a rash on the hands, says Sanna Gunnesson.”
“Oxidized fragrances of aromatherapy oils of the brand Kerstin Florian has given several masseurs and spa personnel contact allergy. Masseuses Mia Senor, Nina Sellman and Sanna Gunnesson got so severe discomfort that they had to change profession. Mia Senor showing us pictures of how her hands and arms might look when she came home from work. It almost looks like a burn. The skin on her hands became all swollen, and her fingers were like glued ogether. – It stung and did hurt so evil, she says, and explains that her hands were so sore and infected that it even went impossible to work with gloves. Sanna Gunnessons trouble also started with eczema on the hands. Since she had no other jobs she stayed at Hagabadet even though it hurt to massage. Eventually, she was itching all over the body.”
Imagine what it does to your skin, and then imagine what it does to your soft tissues in your airways and lungs. So next time you are thinking of putting some fragrance or oil on – Don’t!
