PROPYLENE GLYCOL GRG
Monopropylene Glycol is used for its solvent properties in industry, the personal care market and pharmaceutical industries. It is more widely used as a non toxic anti-freeze, de-icer, heat transfer fluid, a component in hydraulic fluids, and in paints and surface coating industries. MPG has many special features and benefits including, low freezing point, low flammability, low toxicity, biodegradability, low corrosive nature to metals making it an excellent substitute for ethylene glycol.

How to use propylene glycol to make a lava lamp:
The original formula for making lava lamps recommends using propylene glycol at a ratio of 30:70 with water. The lava is simply a mineral oil which floats through the glycol solution after being heated with a 40W bulb
How to make your own DIFFUSER OIL:
- 30% Fragrance oil
- 60-65% DiPropylene glycol or MonoPropylene glycol
- 5-10% Perfumers alcohol (Buy Perfumers alcohol)
To make diffuser oil, blend the fragrance oil with the DPG or MPG until clear. Add Perfumers alcohol to reduce viscosity to desired thickness.

DEPRESSION OF FREEZING POINT OF WATER:
Propylene glycol is a component in newer automotive antifreezes and de-icers used at airports. Like ethylene glycol (MEG), the freezing point of propylene glycol is depressed when mixed with water due to disruption of hydrogen bonding. Unlike ethylene glycol, propylene glycol is much lower in toxicity. It is readily biodegradable.
