In applications where toxicity is a concern, propylene glycol fluid is used because of its low acute oral toxicity vs. the moderate acute oral toxicity of ethylene glycol. If you do not require food grade glycol (lowest oral toxicity), we recommend DOWFROST HD as it provides superior corrosion protection and low oral toxicity. If you require the lowest possible toxicity available, choose DOWFROST antifreeze (non-toxic antifreeze).

Butylene Glycol, Natural is a sustainably-sourced, naturally-derived humectant and carrier material for cosmetic ingredients. It serves the same functionality as the petrochemical-derived butylene glycol, is an effective solvent and coupling agent and its use can improve freeze/thaw stability of cosmetic emulsions.

This food-grade glycol is used as a heat transfer liquid in beer dispensing systems and temperate chillers. Using a mix of glycol and water will allow your cooling fluid to go sub-zero allowing icy cold beer and a frosty font. Glycol mixes are also used in jacketed stainless conical fermenters.

Propylene glycol is also used in a variety of other applications such as anti-freeze, cosmetics, food manufacturing/processing systems, VAC applications, laser cutting, milk & wine production equipment.

Dipropylene glycol with low odour is a high quality grade and with it's low toxicity and solvent properties makes it an ideal additive for perfumes and skin and hair care products. It is also an ingredient in commercial fogging fluids which are used in entertainment industry smoke and haze machines. Ideal for use as a base for Reed Diffusers including Plugin electric types.

Dipropylene glycol is a colourless, nearly odourless liquid with a high boiling point and low toxicity. It is a mixture of three isomeric chemical compounds, 4-oxa-2,6-heptandiol, 2-(2-Hydroxy-propoxy)-propan-1-ol, and 2-(2-Hydroxy-1-methyl-ethoxy)-propan-1-ol.

Alde-branded glycol is recognizable by its blue-green color. It is recommended that you do not mix brands of glycol. If the glycol in your current system is a different brand or a color other than blue-green, we advise that you have the system flushed and refilled with Alde-branded glycol.

Lastly - and this is the reason we know about propylene glycol - it is used in e-liquids for vaping. PG is paired with vegetable glycerin (VG) to form the base of all e-liquids. The PG works well as an emulsifier to keep the ingredients of the e-liquid mixed together. Plus, it works well as a product that can be vapourised and inhaled. The VG acts as a thickening agent - if an e-liquid has more VG in it, then it will produce more vapour and more intense flavour.

Where to buy propylene glycolThe best propylene glycol for vaping will come from a reputable vape retailer, like us Vape Simple - all of our e-liquids contain propylene glycol, vegetable glycerin and flavouring.

Polyethylene glycol-electrolyte solution (PEG-ES) is used to empty the colon (large intestine, bowel) before a colonoscopy (examination of the inside of the colon to check for colon cancer and other abnormalities) or barium enema (a test in which the colon is filled with a fluid and then x-rays are taken) so that the doctor will have a clear view of the walls of the colon. PEG-ES is in a class of medications called osmotic laxatives. It works by causing watery diarrhea so that the stool can be emptied from the colon. The medication also contains electrolytes to prevent dehydration and other serious side effects that may be caused by fluid loss as the colon is emptied.

Polyethylene glycol-electrolyte solution (PEG-ES) comes as a powder to mix with water and take by mouth. Certain PEG-ES products may also be given through a nasogastric tube (NG tube; a tube that is used to carry liquid nutrition and medication through the nose to the stomach for people who cannot eat enough food by mouth). It is usually taken the evening before and/or the morning of the procedure. Your doctor will tell you when you should begin taking PEG-ES, and whether you should take all of the medication at one time or take it as two separate doses. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take PEG-ES exactly as directed. Do not take more or less of it than prescribed by your doctor.

If the fuss over distilled water or propylene glycol is too much maintenance for your taste, you can always consider humidity pouches like those made by Boveda in lieu of a traditional humidification unit. Humidity pouches can be a little more costly in the long run, but they are low maintenance. When your pouches firm up, simply toss them out and replace them with new ones.

Celsius model - Measuring ethylene or propylene glycol concentration has never been easier or more accurate. The MISCO Palm Abbe digital refractometer is the most accurate tester exist for measuring glycol concentration and freeze point in the field.

The Palm Abbe refractometer is fast, convenient, and easy to use. Simply place a drop or two of ethylene or propylene glycol in the stainless-steel sample well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout of ethylene or propylene glycol concentration or freeze point. Nonlinear temperature compensation is automatic and insures that fluids tested between 0 and 50 C (+32 to 122 F) are measured accurately.

Ethylene & Propylene glycol concentration and freeze point are easily read on the large dual-line LCD display, even in dim light. Digital readings remove the subjectivity associated with interpreting where a boundary line crosses tiny scale divisions. And, it is so easy to use! The user interface consists of two buttons, one to take readings and the other to step through various menu options.

Antifreeze is commonly done but like anything else, you have to do it the right way. Do not use automotive antifreeze (ethylene glycol, which also has silicates). Use only propylene glycol such as Noble No-Burst or Downtherm products with inhibitors.

Glycol will find leak points you never imagined, even if the system is now \"tight.\" The lower internal surface tension of glycol tends to find these pathways. Valve stems, screw caps on hose-end valves, weak solder joints. . . you will see it in living color if there are any leaks.

Propyleneglycol is considered non-toxic, or at least the FDA labels it at low-acute oral toxicity. In a food-grade form, PG is actually common in the food industry as a flavor- and scent-enhancer. Look at the labels on stored bakery goods to see PG or some variety used.

If you come across a system with an unknown glycol, the two types can be blended. However you end up with an unknown toxicity concoction. I'd rather the old fluid be flushed and disposed of and start fresh.

First, run a cleaner through the system. I prefer a good hydronic-specific cleaner. Dow suggests a 1-2% solution of TSP. I've had one supplier tell me that automatic dishwasher detergent can be used as it doesn't suds up and it cuts grease and oil well. All these products are basically strong soaps. Be sure any cleaners are completely flushed out before you add the glycol.

Third, select a quality brand and blend it carefully. Glycols should only be blended with filtered DI (deionized) or DM (demineralized) water.Plain tap water may or may not be good to blend with. Hydronic glycols have inhibitor chemicals added. These ingredients help buffer the pH, lock up hardness, scavenge oxygen, etc. If you blend with water of a questionable quality, you will compromise these important components of the glycol right off the bat.

I'd suggest purchasing pre-blended hydronic glycols. Most of the hydronic antifreezes are available in any size container from a five-gallon bucket to a rail-car, pre-blended. Beware of the freeze protection and the burst temperatures on the container label.

Stick with the brand-name products to assure it is first-quality and properly inhibited. If your system contains any aluminum components you MUST use a special AL (aluminum) blend. All of the major hydronic glycol manufacturers offer AL fluids now. Several manufacturers also offer HD (heavy duty) products. These have a better inhibitor package, I suggest HD fluids for solar applications, as they handle over-heating better, and longer.

I would highly recommend any boiler auto-fill systems be disconnected from a system with glycol installed. You can buy, or build a glycol fill tank to assure the system maintains pressure. Most of the newer modulating-condensing boilers require 10-12 psig to fire off. A glycol fill system will assure the system does not lockout due to low-pressure conditions. It is quite possible for a hydronic system to burp a little air as the heating season begins so be sure you cover that loss of pressure to prevent nuisance call backs.

Lastly, invest in glycol testers to maintain your systems. Buy at least a freeze-protection tester, such as a refractometer. Buy a good one that will give you years of service. Also, get a pH tester because this will give you the first sign that the fluid has been compromised. I like the small, pocket-sized electronic type of tester.

Label all the systems where you install glycol! This can be as simple as a magic marker note on the boiler jacket. Many of the glycol suppliers have pre-printed labels for this purpose. Define the type of fluid and the percentage of mix, along with your company name and contact numbers.

Glycol Ether DPM (dipropylene glycol monomethyl ether) is a mid to slow evaporating solvent that has 100% water solubility and is ideally suited as a coupling agent in a wide range of solvent systems.

PEG or polyethylene glycol is a polymeric material composed of ethylene oxide and water as monomers which are not only hydrophilic but also biocompatible. However, it is a synthetic molecule synthesized by polymerizing ethylene oxide where a ring-opening takes place. As it is composed
