The major consumers of polypropylene glycol include the pharmaceutical and food and beverage industry, which account for major share in the market.
They created gels that contain either PEG or another polymer called polypropylene glycol, as well as some that combine those two polymers in different ratios.
Initially, a few flotation trials were conducted to study the effect of frother addition on the recovery of lead and zinc minerals using various types of frother such as ethyl alcohol, polypropylene glycol, cresylic acid, methyl isobutyl carbinol (MIBC) and pine oil (Tan, et al.
The shells were washed, ground up in polypropylene glycol, and exposed to ultrasonic waves that broke the shell fragments down into nanoparticles more than 350,000 times smaller than the diameter of a human hair.

"They have claimed there is no proof that e-cigarettes are safe and yet the chemical in which the nicotine is dissolved in e-cigarettes - polypropylene glycol - has been used as a carrier for drug treatment in hospitals for years.
The aim of the present study is to prepare a novel system of PUDs using castor oil, polypropylene glycol (PPG), toluene diisocyanate (TDI), and (2E)-4-(2,3-dihy-droxypropoxy(-4-oxobut-2-enoic acid [glycol semi-ester (GSE)] as raw materials and to probe the concentration effects of castor oil, GSE, and the polymer on the properties of PUDs.
It must notice that the ester O-MPG (mono propylene glycol is very similar with the previous O-PPG (polypropylene glycol) used in samples of table 1 and table 2 and is easier to obtain at a reproducible chemical structure.
