###Product Overview**
PG, with the chemical formula C 3 H8  O2 , is a colorless, odorless, and viscous organic compound, divided into two isomers: 1,2-propanediol (a mainstream industrial product) and 1,3-propanediol. It has low toxicity, high moisture absorption, excellent solubility, and low temperature stability, and is widely used in industrial antifreeze and chemical synthesis fields. It is an environmentally friendly multifunctional chemical.

###Product features and advantages**
1. * * Safety and Environmental Protection * *:
-Low toxicity characteristics (LD50 higher than ethylene glycol).
2. * * Efficient moisture absorption and moisturization * *:
-Strong moisture absorption, can be used as a moisturizer and wetting agent to stabilize product performance.
3. Wide temperature range adaptability:
-Low freezing point (-60 ºC), high boiling point (188 ºC), suitable for extreme temperature environments.
4. * * Excellent solubility * *:
-It is miscible with water, alcohols, esters, and most organic compounds, making it an ideal solvent and carrier.
5. * * Chemical stability * *:
-Resistant to oxidation, acid and alkali, with stable long-term storage performance.

###* * Main application industries**
1. * * Food and Beverage * *:
-Food humectant, essence/pigment solvent, baking product anti caking agent, beer production line cleaner.
2. * * Pharmaceuticals and Cosmetics * *:
-Drug solvents (oral liquids, injections), ointment bases, cosmetic moisturizers, disinfectant carriers.
3. * * Daily chemical and personal care * *:
-Moisturizing and thickening components of toothpaste, wet wipes, shampoo, and moisturizer.
4. Industrial antifreeze and heat transfer:
-Automotive/aviation antifreeze, solar thermal conductivity fluid, ice rink coolant (environmentally friendly alternative to ethylene glycol).
5. * * Resin and Coatings * *:
-Unsaturated polyester resin raw materials, paint/ink solvents, adhesive plasticizers.
---
###Storage and transportation conditions**
-* * Storage Environment * *:
-Sealed and stored in stainless steel or polyethylene containers, avoiding light and high temperatures (recommended temperature range of 5-30 ºC).
-Store in isolation from strong oxidants such as peroxides and nitricacid, and keep well ventilated and dry.
-Shelf life: Under unopened conditions, the shelf life is 24 months (pharmaceutical/food grade products must be strictly protected from light).
-* * Transportation Requirements * *:
-According to non hazardous chemical transportation (some countries require labeling as "hygroscopic liquid"), sea transportation complies with IMDG regulations.
---
###Safety and operational standards**
-* * Health Tips * *:
-Although it is a low toxicity substance, long-term exposure may cause skin irritation. It is recommended to wear gloves and goggles during operation.
-Leakage Handling:
-Clean up after absorbing with sand or inert adsorbent materials, and rinse contaminated areas with clean water.
-Waste Management:
-Dispose of general industrial waste or local environmental regulations, and treat pharmaceutical grade waste specifically.
