No-rub chug-a-lug?

Would it hurt one to drink contact solution?

Not regularly, but say in an emergency situation. Google is inconclusive, and the packaging merely says not to use it if you're allergic to any of the ingredients.

The stuff I use lists ingredients as: Polyquaternium-1 (0.0011%), Sodium Citrate, Poloxamine, Sodium Lauroyl Lactylate, Sodium Chloride, Borates, Mannitol, and Edetate Disodium (0.05%).

You put it in your eyes, how bad could it be for your stomach?

It's full of salt, so I can't imagine it'd do much good if dehydration is the "emergency situation" you're talking about.

One possible resource [PDF] shows no significant danger.

hmmm.. offhand sodium citrate, sodium chloride (duh), and mannitol (just a sugar alcohol) all sound okay. Polyquaternium-1 is some silly trade name compound they have, isn't it? I wonder how salty it really is, it has to be somewhat isotonic otherwise it'd really burn. I wouldn't imagine it'd be any worse than gatorade, electrolytes-wise.

It's (mostly) saline.

As for salt concentration - it's designed to be isotonic; will not leach nor shove water out of or into your (eye) cells.

I think it would be mostly neutral, fluids wise, if drunk.

You could drink it without ill effect, unless you were allergic to one of the ingredients.

Well, if you were talking about Visine instead of contact lens solution, the answer would be pretty bad. Just because you can put it on your body, doesn't mean you should put it in your body.

Ths doesn't answer your question, but it was related and I thought it was interesting.

Why?

"Just because you can put it on your body, doesn't mean you should put it in your body"

To nitpick, your stomach isn't really "in" your body (topologically speaking). If you think about it, both your stomach/gut and your eye have membranes that things can diffuse through--and into your body...

Doesn't change the answer though, I suppose.

(Perhaps with Visine the issue is the *amount* taken into the body? Even a milliliter of eyedrops is a lot more than you'd normally put into your eye.)

I was under the impression that contact solution is just saline, and that saline is just water that has the same pH as blood. So, working off that, it wouldn't hurt you at all, but it also wouldn't hydrate you because of the salt.

It's all food-grade stuff except for the sodium lauryl lactylate (soap) and Polyquaternium-1 which is a quarternary ammonium compound (antimicrobial). In these quantities I'd say you would be fine drinking a bottle of contact solution.

Also there's a few MSDS for contact solution online (e.g.) and they don't seem to indicate any ingestion hazard.

There's the Johnson and Johnson brand that has a very small trace of the protein deposit dissolvers included in the rinse/storage formula so that you only need to use the one solution. I imagine that drinking that might be less than healthy.

Sorry, not Johnson & Johnson, it's Bausch & Lomb's Renu Multiplus.

From the side of the bottle . . .

CONTENTS: A sterile, isotonic solution that contains HYDRANATE (hydroxyalkylphosphonate), boric acid, edetate disodium, poloxamine, sodium borate and sodium chloride; preserved with DYMED (polaminopropyl biguanide) 0.0001%.

sodium lauryl lactylate (soap)

Or detergent? My understanding is that the lauryls are quite bad for one's health. We just trust that they stay on our scalp (shampoo) or get spit out (toothpaste), instead of being ingested.

I may be out to lunch, though.

Yes, soap, detergent. It can be an irritant in large quantities, and can form dangerous compounds through reaction with a variety of stuff, but eating a little isn't going to kill you, just as getting a mouthful of soapy water by accident (or swallowing some toothpaste) isn't anything to be concerned about.

There's a huge difference between soap and detergent. Soap, I wouldn't worry overly about ingesting; detergent, another story entirely.

Please explain. I use "soap" as a colloquial equivalent to the more scientific "detergent," though I usually use it to refer to the most common kinds of household detergent, sodium alkyl sulfates.
