Oh the uses for glycerin [SEP] This bottle I bought to put a scant teaspoon into my home made ice cream to keep it from forming ice crystals after storing in the freezer.  I just bought a Cuisinart Ice Cream Machine and followed a simple recipe for chocolate ice cream, but I wanted to make sure that it would not become hard and full of ice crystals once I stored it in the freezer, so I did some research online and glycerin is one of several ways to keep ice cream creamy.  It only takes a teaspoon in the recipe and the other thing about glycerin is that it is sweet, so it blends in well with an ice cream recipe.  My ice cream turned out great and it is smooth and creamy after being in the freezer.  Now, this is not my first use of glycerin as I have used a small amount in water to spray in my hair.  Especially on really humid days when my naturally curly hair turns into a frizz-ball, spraying my hair with a 10 parts water, 1 part glycerin (or even less glycerin, depending) keeps my hair from frizzing out so bad.  For me, in ice cream or in my hair, glycerin works great!
