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."

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."

Odor sensitivity and respiratory complaint profiles in a community-based sample with asthma, hay fever, and chemical odor intolerance. [Toxicol Ind Health. 1999 Apr-Jun] - PubMed - NCBI

"...chemical odor intolerance ..., a symptom of multiple chemical sensitivity (MCS), was determined from self-ratings of feeling 'moderately' to 'severely' ill using the Chemical Odor Intolerance Index (CII). Index odors included perfume, pesticide, drying paint, new carpet odor, and car exhaust. Six additional odors [natural gas, disinfectants, chlorinated water, room deodorizers, and environmental tobacco smoke (ETS)] were also assessed in the health and environment survey. Asthmatics reported feeling 'frequently' to 'almost always' ill from the CII index odors of drying paint, new carpet odor, perfume, and cleaning agents compared to nonasthmatics."

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."

Erin Grills's curator insight, March 6, 2013 2:10 PM

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.

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.

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.

Prevalence of fragrance sensitivity in the American Population. [J Environ Health. 2009] - PubMed - NCBI

"Results aggregated from both surveys found that 30.5% of the general population reported scented products on others irritating, 19% reported adverse health effects from air fresheners, and 10.9% reported irritation by scented laundry products vented outside. This study reveals that a considerable percentage of the U.S. population reports adverse health effects or irritation from fragranced products, with higher percentages among those with asthma and chemical sensitivity."
