Antifreeze and Flowers
Name: Jeff H.
Why does antifreeze help preserve plants? As in it can
be used instead of glycerine to preserve the plant when making a floral
arrangement. How is it that anti freeze can be used to do this?
This is more chemistry than botany.
Recommend looking at the chemical properties of propylene glycol to see the
reasons for it being an antifreeze. Propylene glycol also sometimes an
ingredient in ice cream.
