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.

Why perfume could be making you depressed

Why perfume could be making you depressed | Fragrance Chemicals & Health | Scoop.it
"Some people have tremendously adverse reactions to very low levels of chemicals—chemicals most of us can't even smell," says study author Dr. David Katerndahl, a professor of family and community medicine at the University of Texas Health Science Center at San Antonio.

Chemical Watch | News| Increased risk of heart problems following long-term use of cleaning products

Researchers have found that long-term use of household sprays and scented products is associated with reduced heart rate variability in older women, which suggests an increased risk of cardiovascular health hazards.

Endocrine Disruptors and Asthma-Associated Chemicals in Consumer Products

"We detected 55 compounds, indicating a wide range of exposures from common products. Vinyl products contained > 10% bis(2-ethylhexyl) phthalate (DEHP) and could be an important source of DEHP in homes. In other products, the highest concentrations and numbers of detects were in the fragranced products (e.g., perfume, air fresheners, and dryer sheets) and in sunscreens. Some products that did not contain the well-known endocrine-disrupting phthalates contained other less-studied phthalates (dicyclohexyl phthalate, diisononyl phthalate, and di-n-propyl phthalate; also endocrine-disrupting compounds), suggesting a substitution. Many detected chemicals were not listed on product labels."

Romantic, Candle-lit Dinners: An Unrecognized Source Of Indoor Air Pollution

Romantic, Candle-lit Dinners: An Unrecognized Source Of Indoor Air Pollution | Fragrance Chemicals & Health | Scoop.it

"Burning candles made from paraffin wax -- the most common kind used to infuse rooms with romantic ambiance, warmth, light and fragrance -- is an unrecognized source of exposure to indoor air pollution, including the known human carcinogens, scientists report."

Effect of acute exposure to a complex fragrance on lexical decision performance [Chem Senses. 2009] - PubMed - NCBI

"Exposure to the fragrance did not affect high-frequency word recognition. However, there was an order of administration effect for low-frequency word recognition accuracy... The presence of fragrance in the second session apparently served as a distraction that impaired lexical task performance accuracy. The introduction of fragrances into buildings may not necessarily facilitate all aspects of work performance as anticipated."

Toxic effects of air freshener emissions [Arch Environ Health. 1997 Nov-Dec] - PubMed - NCBI

"Emissions of this air freshener at several concentrations (including concentrations to which many individuals are actually exposed) caused increases in sensory and pulmonary irritation, decreases in airflow velocity, and abnormalities of behavior measured by the functional observational battery score... the authors noted the presence of chemicals with known irritant and neurotoxic properties. The Material Safety Data Sheet for the air freshener indicated that there was a potential for toxic effects in humans... The results demonstrated that the air freshener may have actually exacerbated indoor air pollution via addition of toxic chemicals to the atmosphere."

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.

Fragrance chemicals lyral and lilial decrease viability of HaCat cells' by increasing free radical production and lowering intracellular ATP level: Protection by antioxidants. [Toxicol In Vitro. 20...

"We investigate in this study the biochemical effects on cells in culture of two commonly used fragrance chemicals: lyral and lilial... We propose lyral and lilial as toxic to mitochondria that have a direct effect on electron transport chain, increase ROS production, derange mitochondrial membrane potential, and decrease cellular ATP level, leading thus to cell death."

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.

Study Highlights Hidden Dangers In Everyday Products -- Even The "Green" Ones - Forbes

Study Highlights Hidden Dangers In Everyday Products -- Even The "Green" Ones - Forbes | Fragrance Chemicals & Health | Scoop.it

"A first-of-its-kind, peer-reviewed study published in Environmental Health Perspectives... reveals an alarming number of unlabeled chemicals of concern in commonly used household and personal care products" ...

 

"Fragranced products – including air fresheners, dryer sheets, and perfume – and sunscreens had the largest number of target chemicals and some of the highest concentrations. Fragrances can trigger asthma and some have been shown to mimic estrogen, including making breast cancer cells grow in laboratory studies."

Sensory irritation and multiple chemical sensitivity [Toxicol Ind Health. 1999 Apr-Jun] - PubMed - NCBI

"In laboratory testing in which mice breathed the dilute volatile emissions of air fresheners, fabric softeners, colognes, and mattresses for 1 h, we measured various combinations of SI and PI as well as airflow decreases (analogous to asthma attacks)... The response was not a generalized stress response because it occurred with only some mixtures of irritants and not others; it is a specific response to certain mixtures of airborne chemicals."

Silver nanoparticle-induced mutations and oxidative stress in mouse lymphoma cells [Environ Mol Mutagen. 2012] - PubMed - NCBI

"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."
