Influence of environment exposures on the frequency of contact allergies in children and adolescents. [Ann Agric Environ Med. 2012] - PubMed - NCBI

Much concern is provoked by the higher rates of sensitization to fragrances in younger children, compared to adolescents, which may be attributed to the higher exposure nowadays of infants and children to fragrant products. On the other hand, a limitation of exposure to the preservatives thimerosal and Kathon CG has resulted in decreased rates of sensitization to these haptens. Altogether, these observations demonstrate that the rates of contact sensitizations in children reflect changes in their environment, and limitations imposed on the use of haptens with strong sensitizing properties, may be an effective tool in the prevention of contact allergy.

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."

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."

EHP – Formaldehyde and Epigenetic Alterations: MicroRNA Changes in the Nasal Epithelium of Nonhuman Primates

Background: Formaldehyde is an air pollutant present in both indoor and outdoor atmospheres. Because of its ubiquitous nature, it is imperative to understand the mechanisms underlying formaldehyde-induced toxicity and carcinogenicity. MicroRNAs (miRNAs) can influence disease caused by environmental exposures, yet miRNAs are understudied in relation to formaldehyde. Our previous investigation demonstrated that formaldehyde exposure in human lung cells caused disruptions in miRNA expression profiles in vitro. ...


Conclusions: Formaldehyde exposure significantly disrupts miRNA expression profiles within the nasal epithelium, and these alterations likely influence apoptosis signaling.

Environmental Illness Network Minnesota's insight:

According to the EPA (http://www.epa.gov/kidshometour/products/airf.htm), formaldehde is one of the four basic ingredients of air fresheners.

Enviroblog: "Natural" Extracts Can Trigger Allergies

Enviroblog: "Natural" Extracts Can Trigger Allergies | Fragrance Chemicals & Health | Scoop.it

"Some of the natural extracts the EC categorizes as "established allergens" in people are several citrus oil extracts such as citrus bergamia and citrus limonum found in dish soaps and all-purpose cleaners, rose flower oil found in some botanical air fresheners and lavender extract added to detergents and spot removers. These essential oils may trigger an allergic reaction after a few contacts or can cause someone to develop an allergy over a longer period of time."

Ce n'est pas parce que les extraits sont naturels qu'ils ne sont pas nocifs.

Certaines personnes, étant plus sensibles que d'autres, peuvent, malheureusement, développer des allergies, des réactions cutanées et déclencher des crises d'asthme.

Alors, prudence ! Surtout avec les produits d'entretien et cosmétiques soit-disant safe. A fortiori, quand tout le marketing développé autour des normes et des certifications bio et autres peut être trompeur ! Très trompeur !

Cleaning products and air fresheners: emissions and resulting concentrations of glycol ethers and terpenoids. [Indoor Air. 2006] - PubMed - NCBI

While effective cleaning can improve the healthfulness of indoor environments, this work shows that use of some consumer cleaning agents can yield high levels of volatile organic compounds, including glycol ethers--which are regulated toxic air contaminants--and terpenes that can react with ozone to form a variety of secondary pollutants including formaldehyde and ultrafine particles.

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. ...

 

[Common exposure sources include:]

 

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."

"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."

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.
