Is There Any Problem If I Use Glycerin as Anti-Freeze?

Like ethylene glycol and propylene glycol, glycerol dissolved in water disrupts the hydrogen bonding between water molecules such that the mixture cannot form a stable crystal structure unless the temperature is significantly lowered. The minimum freezing point temperature is at about -36 °F / -37.8 °C corresponding to 60-70 % glycerol in water.^[11]

Glycerol was historically used as an anti-freeze for automative applications; due to the abundance of glycerol, its use as an anti-freeze is being re-examined. In comparison, the minimum freezing point of a glycerol-water mixture is higher than an ethylene-glycol mixture; on the other hand, glycerol is not toxic like ethylene and propylene glycols.^[12]

In the laboratory, glycerol is a common component of solvents for enzymatic reagents stored at temperatures below 0 °C due to the depression of the freezing temperature of solutions with high concentrations of glycerol. It is also dissolved in water to reduce damage by ice crystals to laboratory organisms that are stored in frozen solutions, such as bacteria, nematodes, and fruit flies. As for your quipment, consult the manufacturers specs for the process intended. I feel the temperatures involved may be more of an issue than the use of dilute glycerol itself. P.S. Read the whole Wiki article here.

Bro I have already read those materials ..... i just want to know some practical experience & technical problems with Glycerin ....... r u getting me?? .....
