Sometimes, we call this substance an alpha-propylene glycol to easily distinguish it from propane-1,3-diol. 182.1. However, polymerization of ethylene glycol to polyethylene glycol turns the -OH groups into ester linkages: -O-CH2-CH2-O-CH2-CH2-O-CH2-. Many pharmaceutical drugs which are insoluble in water utilize propylene glycol as a solvent and carrier; benzodiazepine tablets are one example.

Large quantities of dissolved oxygen (DO) in the water column are consumed when microbial populations decompose propylene glycol. The number one difference between the two glycols is that ethylene glycol is toxic and propylene glycol is not, allowing propylene glycol to be purchased as food grade in addition to the technical or industrial grade. Propylene glycol is often used to maintain the moisture in prepared foods and works to maintain their flavor quality for longer periods of time. Is caprylyl glycol same as propylene . The thing that PEG is best at is enhancing penetration. Chemically, butylene glycol is a type of molecule that consists of 4 carbon atoms and two OH (alcohol) groups. The key difference between polyethylene glycol and propylene glycol is that polyethylene glycol is a polymer material, whereas propylene glycol is a single molecular compound that can be named a diol. Propylene glycol is an approved food additive for dog and sugar glider food under the category of animal feed and is generally recognized as safe for dogs,[62] with an LD50 of 9mL/kg. Pentylene glycol does not have any evidence to suggest toxicity or carcinogenicity. 87, pp. But opting out of some of these cookies may affect your browsing experience.

[6] In alcohol-based hand sanitizers, it is used as a humectant to prevent the skin from drying. Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions. It's similar to propylene glycol (which has 3 carbon atoms instead of 4) and glycerol (which has 3 carbon atoms, but with an additional alcohol group). The thing that PEG is best at is enhancing penetration. Wow, Thank You everyone for sharing your personal stories snd information. ( 1) Another name for it is "propane-1,2-diol," which is sometimes used when listing it as a compound on ingredient labels. And, thank you for sharing so scary ~ I also had a crazy reaction to the covid Pfizer vaccine ~ when I pressed them they said that PEG can cause allergy for a small number of people for me it caused a neurological & systemic reaction that lasted almost 8 weeks your post helps me narrow down that this really was most likely the cause. "[65], Estimates on the prevalence of propylene glycol allergy range from 0.8% (10% propylene glycol in aqueous solution) to 3.5% (30% propylene glycol in aqueous solution). Pentylene Glycol is used in combination with hydrocortisone and anti-inflammatory, to relieve minor skin irritation, temporary itching and inflammation. People against the use of propylene glycol in food argue that its levels in food are beyond what the World Health Organization recommends. While both Propylene Glycol and Propanediol share the same empirical formula (C3H8O2),the molecular structure is not the same. While it is a low-toxicity substance, you may develop health complications if you eat foods that have it in large quantities. Talking to eachother helps! [51], According to a 2010 study, the concentrations of PGEs (counted as the sum of propylene glycol and glycol ethers) in indoor air, particularly bedroom air, has been linked to increased risk of developing numerous respiratory and immune disorders in children, including asthma, hay fever, eczema, and allergies, with increased risk ranging from 50% to 180%. [57] Ruddick (1972) also summarized intramuscular LD50 data for rat as 13-20 mL/kg BW, and 6 mL/kg BW for the rabbit. If cloudiness or solubilityissues arise, mix the Propanediol into the water phase and/or increase the temperature. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry.
