PPG-2 methyl ether, PPG-3 methyl ether, and PPG-2 methyl ether acetate are used in cosmetics as fragrance ingredients and/or solvents at concentrations of 0.4% to 2%. Propylene glycol ethers are rapidly absorbed and distributed throughout the body when introduced by inhalation or oral exposure, but the inhalation toxicity of PPG-2 methyl ether vapor, for example, is low. Aerosols, such as found with hair sprays, produce particle sizes that are not respirable. Because these ingredients are…

Hazardous substances in frequently used professional cleaning products
TLDR
It is hypothesized that chemical substances present in cleaning products are known health hazardous substances that might be involved in adverse health effects of the skin and the respiratory tract.

TLDR
Methods were developed and validated for personal monitoring of exposures to airborne glycol ethers, both short-term and long-term time-weighted-averages, allowing assessment of human airborne exposures relative to the new toxicology data available on animals.

TLDR
DPGME appears to have a low subchronic vapor inhalation toxicity hazard and there were no effects attributed to exposure to DPGME at any exposure concentration in either male or female rats or rabbits.

Local Ophthalmic Effects of Dipropylene Glycol Monomethyl Ether
TLDR
Results showed undiluted dipropylene glycol mono-methyl ether (DPGME) to cause moderately severe conjunctoblepharitis which began to resolve by 24 hr with no residual injury by 7 days, and corneal thickness increased following instillation of 0.1 ml DPGME.
Aerosol Measurement: Principles, Techniques, and Applications
TLDR
The fundamental principles used in deciding which aerosol properties to measure and how to interpret the results are offered and two new chapters have been added: one on historical aspects of aerosol measurements and the other on real-time single particle analysis.
