Creamer is made of an oil, and emulsifier, and a sweetener. It is by definition dairy free. The word was invented to make it sound like cream, without actually calling it cream, because it a similar effect as cream on coffee (it "creams" the coffee, making it a cream-ER). Half and half, on the other hand, is basically half skim milk, half cream.

There are 'half-and-half' style creamers though.
