The Scary Truth About Air Fresheners

The Scary Truth About Air Fresheners | Fragrance Chemicals & Health | Scoop.it

 

"When life stinks, the $8.3 billion global air-freshener industry is here to mask its scent. But, as the Natural Resources Defense Council (NRDC) and leading pollutant exposure researchers are finding, there’s a price to pay for making a pungent post-party dorm room suddenly smell like a morning meadow. Turns out, many air fresheners release toxic chemicals and organic compounds that can rough up everything from our skin to male reproductive systems."

Caution: These seven household items may feminize baby boys - Environmental Working Group

"High phthalate levels have been linked to decreased sperm motility and concentration and altered hormone levels in adult men; in a recent study of 134 newborn boys and their mothers, researchers found distinct differences in the reproductive systems of the boys whose mothers had the highest phthalate levels during pregnancy. Further research revealed that those moms' phthalate levels weren't uncommon -- in fact, an estimated one quarter of American women would have similarly high phthalate levels. ...

Fragrance: Diethyl phthalate (DEP) is often used as part of the "fragrance" in some products. Since DEP won't be listed separately, you're better off choosing personal care products, detergents, and cleansers that don't have the word "fragrance" on the ingredients list. ...

 

Air Fresheners: New research from the NRDC demonstrates that, just like fragrances in personal care products, most air fresheners contain phthalates. That even goes for the ones labeled "fragrance free." NRDC suggests that you open your windows and use fans to circulate air and keep it fresh."

EHP – Phthalate Exposure and Allergy in the U.S. Population: Results from NHANES 2005-2006

"Conclusion: In this cross-sectional analysis of a nationally representative sample, HMW phthalate metabolites, particularly MBzP, were positively associated with allergic symptoms and sensitization in adults, but there was no strong evidence for associations between phthalates and allergy in children aged 6-17 years."

Environmental Illness Network Minnesota's insight:

Phthalates are common ingredients in air fresheners and other fragranced products.

Trigger factors mainly from the environmental type are reported by adolescents with migraine. [Arq Neuropsiquiatr. 2013] - PubMed - NCBI

"Results: Fifty of the participants exhibited chronic migraine and the other 50 participants demonstrated episodic migraine. The most common group of trigger factors reported was the environmental one, mainly sun/clarity, followed by hot weather and the smell of perfume. Conclusions: Ninety-one percent of children and adolescents with migraine reported a trigger factor precipitating the migraine attack."

Impact of air fresheners and deodorizers on the indoor total volatile organic compounds [Kokuritsu Iyakuhin Shokuhin Eisei Kenkyusho Hokoku. 2007] - PubMed - NCBI

In this study, we investigated the emission rate of VOCs and carbonyl compounds for 30 air fresheners and deodorizers by the standard small chamber test method (JIS A 1901). The total VOC (TVOC) emission rates of these household products ranged from the undetectable level (< 20 microg/unit/h) to 6,900 microg/unit/h. The mean TVOC emission rate of the air fresheners for indoor use (16 products) was 1,400 microg/unit/ h and that of the deodorizers for indoor use (6 products) was 58 microg/unit/h, indicating that the fragrances in the products account for the major part of the TVOC emissions. Based on the emission rates, the impacts on the indoor TVOC were estimated by the simple model with a volume of 17.4 m3 and a ventilation frequency of 0.5 times/h. The mean of the TVOC increment for the indoor air fresheners was 170 microg/m3, accounting for 40% of the current provisional target value, 400 microg/m3. These results suggest that daily use of household products can significantly influence the indoor air quality.

ScienceDirect.com - Environmental Impact Assessment Review - Fragranced consumer products: Chemicals emitted, ingredients unlisted

"We investigated volatile organic compounds (VOCs) emitted from 25 common fragranced consumer products—laundry products, personal care products, cleaning supplies, and air fresheners—using headspace analysis with gas chromatography/mass spectrometry (GC/MS). Our analysis found 133 different VOCs emitted from the 25 products, with an average of 17 VOCs per product. Of these 133 VOCs, 24 are classified as toxic or hazardous under U.S. federal laws, and each product emitted at least one of these compounds."

This article does not show an advancement made to better chemical engineering, but i plan to use this to show possible advancements. I think I am going to end my presentation with new advancements that can be made, and I believe that this will be a good topic to show. Chemcial engineers would be the people who work with the production factories to cut down on the toxic ingredients and create a cleaner, safer product.

"Silver nanoparticles (Ag-NPs) have increasingly been used for coatings on various textiles and certain implants, for the treatment of wounds and burns, as a water disinfectant, and in air-freshener sprays. The wide use of Ag-NPs may have potential human health impacts... These results suggest that 5 nm Ag-NPs are mutagenic in mouse lymphoma cells due to induction of oxidative stress by the Ag-NPs."

Why You Need to Ditch Dryer Sheets - EcoWatch

Why You Need to Ditch Dryer Sheets - EcoWatch | Fragrance Chemicals & Health | Scoop.it

 

"Fragrances can include tens to hundreds of different chemicals, some of which are toxic, and many of which are known allergens, like limonene and linalool. All fragrance chemicals are usually kept secret from consumers. Dryer sheets can contain volatile organic compounds like acetaldehyde and butane, which can cause respiratory irritation. Quats, a fabric softener chemical, is often part of a family of chemicals called quaternary ammonium compounds, many of which are linked to asthma. Acetone, used in dryer sheets, can cause nervous system effects like headaches or dizziness.

 

Not surprisingly, when asked, survey respondents frequently report adverse health effects from exposure to dryer vents. One study found nearly 11 percent of the respondents reported irritation from exposure to emissions from dryer vents vented outside. Nearly 40 percent of respondents who indicated that they were “chemically sensitive” reported irritation from dryer vent emissions."

"When you apply anything labeled with a "fragrance" ingredient today, you can be assured you are subjecting yourself to anywhere from tens to hundreds of various chemicals. This includes lotions, which you may apply to your entire body, facial skin care products and other beauty and self care items that you may use every single day, multiplying your exposure exponentially. None of these chemicals need to be directly disclosed in labeling since they are considered proprietary in nature."
