There are two types of RV antifreeze on the market. One has propylene glycol and the other has ethylene gylcol. Both are pink and don't assume just because it is pink (as opposed to the green automotive stuff) that it has the same characteristics. Camco makes both types so read the label before purchasing...
Pros & cons of each type:

Propylene glycol is used in a lot of ordinary consumer products that are ingested or applied to the skin and is considered safe. This is the one you want to put in your water lines.
Ethylene glycol is the primary ingredient in automotive antifreeze which is highly toxic. It is a poor choice for RV water lines for a number of reasons as in the above links but the RV product is not considered toxic.
Unfortunately the ethylene glycol version costs less to produce and is what you'll usually find on a shelf. A lot of users don't know that there are two types and buy simply based on price. I've found that with some of the containers you have to look hard to find the ingredients on it. I had to hunt all around locally to find the "good stuff" and only one place had it. It was only like $1 more a jug than the cheap stuff.
