Air Sanitizers- US EPA Document Air Sanitizers DIS/TSS-11 / Sep. 3, 1980 EFFICACY DATA AND LABELING REQUIREMENTS: Air Sanitizers These requirements apply to products with label claims for the treatment of air to reduce the numbers of airborne microorganisms.
Analysis of refill liquids for electronic cigarettes Journal Article AIMS: To assess levels of nicotine, nicotine degradation products and some specific impurities in commercial refill liquids for electronic cigarettes. DESIGN AND SETTING: We analyzed 20 models of 10 of the most popular brands of refill liquids, using gas and liquid chromatography.
Comparison of the effects of e-cigarette vapor and cigarette smoke on indoor air quality Journal Article CONTEXT: Electronic cigarettes (e-cigarettes) have earned considerable attention recently as an alternative to smoking tobacco, but uncertainties about their impact on health and indoor air quality have resulted in proposals for bans on indoor e-cigarette use. OBJECTIVE: To assess potential health impacts relating to the use of e-cigarettes, a series of studies were conducted using e-ci…
Electronic cigarettes as a harm reduction strategy for tobacco control: A step forward or a repeat of past mistakes? Journal Article Abstract The issue of harm reduction has long been controversial in the public health practice of tobacco control. Health advocates have been reluctant to endorse a harm reduction approach out of fear that tobacco companies cannot be trusted to produce and market products that will reduce the risks associated with tobacco use.

Experimental exposure to propylene glycol mist in aviation emergency training: acute ocular and respiratory effects Journal Article OBJECTIVES— Propylene glycol (PG) (1-2 propanediol; CAS No 57-55-6) is a low toxicity compound widely used as a food additive, in pharmaceutical preparations, in cosmetics, and in the workplace—for example, water based paints, de-icing fluids, and cooling liquids. Exposure to
Health effects of Theatrical Haze Document The major findings of this study are summarized below: • No evidence of serious health effects was found to be associated with exposure to any of the theatrical effects evaluated in this study. • Peak exposures to elevated localized air concentrations following a release of glycol smoke are associated with increased reporting of respiratory, throat, and nasal symptoms, and findings of vocal cord inflammation.
Heat degradation studies of solar heat transfer fluids Journal Article Destructive distillation of solar heat transfer fluids was conducted to determine the types of pyrolytic products which might be formed in solar collectors under conditions of stagnation or malfunction.
Key Issue: Glycerin | U.S. Pharmacopeial Convention Web Page Monograph Revisions At the request of the Food and Drug Administration (FDA), USP has revised and strengthened its Glycerin Monograph to prevent future diethylene glycol (DEG) and ethylene glycol (EG) adulteration.
Key Issue: Revision of Excipient Monographs Related to DEG & EG Adulteration | U.S. Pharmacopeial Convention Document Revised Monographs Based on a request from the Food and Drug Administration (FDA) in February 2009, USP has revised and strengthened its monographs for five pharmaceutical excipients used in drug formulations-Propylene Glycol
Propylene glycol - Wikipedia Encylopedia Article Propylene glycol, also called 1,2-propanediol or propane-1,2-diol, is an organic compound (a diol or double alcohol) with formula C3H8O2. It is a colorless, nearly odorless, clear, viscous liquid with a faintly sweet taste, hygroscopic and miscible with water, acetone, and chloroform.
The Bactericidal Action of Propylene Glycol Vapor on Microorganisms Suspended in Air II. the Influence of Various Factors on the Activity of the Vapor Journal Article A study of the conditions which affect the bactericidal action of propylene glycol vapor on air-suspended microorganisms has been carried out. The killing process was found to be more effective when both the total number of air-borne droplets and the number of organisms in the bacterial suspension are small. A temperature belo…
The Bactericidal Action of Propylene Glycol Vapor on Microorganisms Suspended in Air. I Journal Article It has been found that propylene glycol vapor dispersed into the air of an enclosed space produces a marked and rapid bactericidal effect on microorganisms introduced into such an atmosphere in droplet form. Concentrations of 1 gm. of propylene glycol vapor in two to four million cc. of air produced immediate and complete sterilization of air into which pneumococci, streptococci, staphylo…
THE MECHANISM OF AERIAL DISINFECTION BY GLYCOLS AND OTHER CHEMICAL AGENTS - 1 Journal Article Theoretical analysis of the mechanism of action of chemical aerial disinfectants reveals that the rapid killing action which is obtained cannot be accounted for by a collision process between germicidal aerosol particles and the air-borne bacteria. However, a mechanism involving condensation of germicide molecules in the vapor state on to the bacteria-containing droplets results in a theoretical ve…
THE MECHANISM OF AERIAL DISINFECTION BY GLYCOLS AND OTHER CHEMICAL AGENTS - 2 Journal Article The effectiveness of any compound as an aerial germicide depends upon the extent of condensation of its vapor on air-suspended bacteria, and on the rate at which the resulting concentration of germicide can produce death of the microorganisms. The properties of any compound conducive to production of the highest rate of kill of air-borne microorganisms by means of the smallest possible concentratio…
Toxins in E-Cig Vapor Also Found in Human Breath and Outdoor Air Manuscript Summary * Five of the volatile organic compounds detected by various studies in electronic cigarette vapor have also been found in human breath emissions (acetaldehyde, acetone, butanone, formaldehyde and isoprene).
