MrDuke September 25, 2008 Share MrDuke Member September 25, 2008 I need a substance that gels in room temperature tap water (no heating to activate) AND isn't harmful to ingest. Carbomers? Agar? Pharmaceutics is a distant memory, right up there with the first 2 years of college. If you read all that without snickering, +2 for you. Link to comment Share on other sites More sharing options...

Preacher September 25, 2008 Share Preacher Member September 25, 2008 you have to refrigerate it. How thick of a consistency do you need? Link to comment Share on other sites More sharing options...
MrDuke September 26, 2008 Author Share MrDuke Member September 26, 2008 jello-like. It needs to gel at room temp at stay solid at room temp. Link to comment Share on other sites More sharing options...
Preacher September 26, 2008 Share Preacher Member September 26, 2008 (edited) that is difficult to say since you also need it edible, balistic gelatin or fish based gelitin works at room temp but the balistic gelatin is very expensive. What are you trying to do here? Edited September 26, 2008 by Preacher Link to comment Share on other sites More sharing options...

What are you trying to do here? not necessarily edible, but not harmful if swallowed. I need to gelatinize a bitter apple mix for vet use. How expensive and easy to acquire is the balistic gel? Cheaper forms? I'm still looking at the carbomer line. I don't know the difference between 940, 3323, etc. Link to comment Share on other sites More sharing options...
Preacher September 26, 2008 Share Preacher Member September 26, 2008 I used to mix the stuff for firearms testing in the army, was some fun stuff but it isn't really the best for eating I wouldn't think. It's nasty looking anyway looks like yellowed fat, a little opaque. I never tested it to eat but it prolly wouldn't hurt you. As far as finding it, I have no clue.

Shazz September 26, 2008 Share Shazz Member September 26, 2008 http://www.kbescientific.com.sg/science_demonstration.htm You can buy this stuff (if it's what you need)..look 17 down you will see the crystals to mix with water at room temp and it makes a gel We used this stuff at a church function for kids. hilarious! might be harmful to ingest though..

Shropshire Slasher September 26, 2008 Share Shropshire Slasher Member September 26, 2008 Regular gelatin (Knox) in white and orange box will mix with cold water. When using it in a recipe, you "bloom" it in cold liquid. The gelatin protein traps the liquid, thus thickening it. If you use a high gelatin to liquid ratio, the result is a mass that is not solid like set Jell-O, but not a liquid either. It is not dissimilar to the gel inside of a baby diaper when it has been exposed to liquid, if you've ever seen that. (actually, if you haven't, it is fun to experiment with). Try the gelatin and see if it will work. Might need a bit of experimentation. Sorry, you asked for a Chemical Engineer. I'm only a lowly Physicist, so forgive me for butting in.

I'll whip up a few tests with the Knox, but I'm guessing I'll need something that forms more of a solid. I never thought of diaper material... I'll try that tonight too. Any comments on the carbomers? What's the diff between the suffixes? I need something permanent. Link to comment Share on other sites More sharing options...

MrDuke September 27, 2008 Author Share MrDuke Member September 27, 2008 It started as a vet need, but has grown into something different. Now the goal is: Add a solidifying agent (<--goal) to a 1 oz bottle, add room temp water, shake it, sip Coke and watch it turn into a solid. Not a ball of fiberglass resin, but jello-ish or better. It CANNOT go back into solution by changing temperature (within reason) or adding more water. Winner gets a case at FF09. Link to comment Share on other sites More sharing options...
