Prefenz: A Hand Sanitizer?

Germ Free 24, Prefenz, and MRSAnator

Recently both the Muscatine Journal and the Quad-City Times have posted news articles (both linked to in the product website) about the hand sanitizer product called Prefenz.  Both articles seem to preach the gospel of this product being an effective hand sanitizer. According to these news articles, this product not only kills MRSA, Strep, and E.Coli, among other bacteria, fungi, and viruses, but it does so for 24 hours after application. That is a pretty impressive claim. The company president of Prefenz Botanicals, Aaron Powers, is even seen in this youtube video claiming that Prefenz  “is the only FDA listed hand sanitizer product that completely eradicates the swine flu”.

Wow. If this is the case, then sign me up. I actually have a bottle in the bathroom right now, and have been using the product for a few days. It allegedly creates a barrier all over your hands that kills the bad stuff for up to 24 hours. It definitely feels like I have a barrier on my hands right now, and I like how it feels. Its not like you have dried Elmer’s glue on your hands or anything.  In fact, the sensation that I have a barrier on my hands is so faint and light, that it could be a pretty convincing mind trick. If this stuff does what it says, it truly is an amazing product.

The problem is, the current atmosphere surrounding the H1N1, and all that has introduced an excellent opportunity for snake oil salesmen.The government’s FDA website has an FDA 2009 H1N1 (Swine) Flu Page that contains several consumer protection links concerning fraudulent H1N1 claims and bogus H1N1 products. It even offers an embeddable widget for your website that will help identify these shenanigans, and there is a category in it for hand sanitizers. Now, Prefenz is not currently listed as being bogus or anything, but it did help me appreciate the weight of the claims made. One would think that maybe the Muscatine Journal or the Quad City Times would have provided credible links or references to studies that back up these claims, but it pretty much just quotes the website or product makers concerning those claims. The actual Profenz website isn’t much more helpful in providing third-party or other independent sources confirming the efficacy of the claims. In all fairness, the Muscatine Journal article does reference a study done by Iowa State University, but here is the quote:  “According to Reusswig, Prefenz has been tested by Iowa State University and other researchers for use against bacteria, viruses and fungi.” Well, the Muscatine Journal didn’t bother to actually check this claim seeing as it basically just says that this David Reuswig says its so. David Reuswig is president of Northern Filter Media. Northern Filter Media are partners with Prefenz. Their home website prominently features “Swimming Pool Filter Media”. Related hand sanitizer Germ Free 24 from Coating Systems Laboratories also advertises a line of pool products, so I guess that Northern Filter Media may not be an unbiased source.

Right, so where did I come up with this other company Coating Systems Laboratories? Well, the key ingredient in Prefenz is something called amosilq, a silica complex which is a …wait for it…silylated quaternary ammonium compound. This ideally provides residual antimicrobial protection, meaning it lasts a relatively long time, longer than the time it takes for alcohol-base Purell to evaporate anyway. Well, all three of the above pictured products contain amosilq. Those are Germ Free 24, Prefenz, and MRSAnator. I mentioned before the Muscatine Journal trusting that these Iowa State University tests were legit, well, turns out there is a study done by Iowa State University. Keep in mind though, that the study was financed by Northern Filter Media, partners with Prefenz. Also the study very plainly starts off with “In this communication we report the effectiveness of these sanitizers for killling human enteric pathogens on inanimate surfaces…”. Now that sounds like a pretty qualified statement, but this is a study. Also, I can be a pretty lazy guy, but I don’t think I would call my hands “inanimate surfaces”. Sanitizing inanimate surfaces  and grippy grabby human meat mits over the course of a very hands-on 24 hours are two totally different things.

I guess what I’m getting at is that these guys haven’t proven to me that this stuff does what it says it will. I like the feel of the stuff and I really hope it does what it says it does, but I’m not convinced that its not just snake oil in this application. I like this study I found the link to at Hand Hygiene Facts. A news channel compared different hand sanitizers by using actual kid hands! I’d like to see Prefenz stack up to this test, including the 24 hour claim.

A review of Pokemon Platinum for the Nintendo DS

I’ve THOUGHT about playing a Pokemon game for a long time, because of the pop icon status these card and video games have garnered over the years. It is especially odd that I never got around to playing any of them because I’ve been a huge Nintendo fan ever since the NES days. Of course, the only handheld games I really began playing in earnest were on the Gameboy Advance, so any Pokemon game on the Fatboy, or Gameboy Color would not have gotten my attention. Portable gaming in those days for me was definitely limited to Tetris, as it was for many people I imagine.

There was also the stigma it had of being a little kid’s obsession. Well, after reading over and over of there actually being some genuine appeal and gameplay involved in them, I decided to try it out. Now I’ve sunk a combined 55 hours into it. I’ve been playing it since March 2009. Previous to this game, my pokemon expertise consisted of being a dedicated Mewtwo player on Super Smash Brothers Melee (one of my top ten favorite games). I thought about picking up either Pokemon Diamond or Pearl on the DS, but I didn’t know which one to get. With Platinum, there was only one, and it also launched near to my visit to the Nintendo World Store in NY. I figured that would be a great place to buy my first pokemon game.

The game has two settings, the world exploration and the battle screen. The world exploration has the towns and trails between them. There are pokemon trainers scattered liberally across the world (of which you also are one).Upon seeing you, the trainers will challenge you to battle. There are also specific terrain types, that when walking through will randomly throw you into battling a wild pokemon, unaccompanied by a trainer. You never see these wild pokemon on the world exploration screen, but you only know one is there when you are forced to do battle. The world exploration features a pleasant top-down view, with simplistic character sprites, and cartoony houses and cartoony landscape features. Its colorful, crisp and very retro. It feels like you are wandering around a much friendlier Hyrule, from The Legend of Zelda: A Link to the Past. You can explore towns, houses, caves, mountains, oceans, and lakes, and it usually pays off to wander quite a bit.

The battle screens were less impressive. This game has been around a long time, the first one being released in 1998 in North America. The battle screen hasn’t changed a whole lot since then, even with the relatively capable technical abilities of the Nintendo DS. The battles consist of pretty much static almost unanimated characters stiffly bumping into each other. Its turn-based and most of the action is explained as it unfolds via text at the bottom of the screen. The disappointment with this though is really mostly just with the dated appearance of the animations and graphics. The gameplay that happens is pretty addictive. The pokemon come in several different types, ranging from ice to fire to rock, and there is a complicated rock/paper/scissors balancing act going on that determines how effective a given pokemon will be against another type. Wild pokemon can either be defeated for the experience points or captured to be added to your pokemon collection. You can only carry six pokemon at a time, but you can change up that roster with access to your whole collection, balancing out the six with a good range of different types and levels.

The actual pokemon characters themselves I really enjoyed. The animations aren’t great, but the illustrations are cool, especially the little pixelated sprites that represent the larger designs. I like the sheer number of pokemon in the game as well. There are a ton, not even including the evolved versions that one pokemon will change from as it levels up. The creatures are really bizarre combinations of each other, with some pokemon not seeming that different from another. Some are inspired from animals,insects and plants, and some are seemingly made up out of thin air. It reminded me of my M.U.S.C.L.E. (Millions of Unusual Small Creatures Lurking Everywhere) collection when I was little. The little pink inch-high rubber action figures were also from Japan and featured nonsensical character designs. Its just very fun collecting all these bizarre little things.

I remember you guys!

I remember you guys!

I beat the equivalent of eight boss battles. In the game, the towns contain gyms which house gym leaders, powerful pokemon trainers. There are eight gym leaders, and I beat them all. After I beat them however, I came across the “elite four”, which I hope are actually the last four trainers to beat. They are incredibly difficult, and have to be beat consecutively without any retreat between the four battles. I beat the first elite, but am stalled after that. I’m giving the game a rest for now, because I’ve been really wanting to start playing Retro Game Challenge. I definitely see myself coming back to Pokemon Platinum, and leveling up my pokemon in the wild sufficiently enough to beat the elite four. Maybe after Retro Game Challenge I’ll come back to it. Pokemon Platinum was a laid back game to play, and I liked the pacing of it as a handheld game. I would highly recommend it, and I’m sure I’ll be buying another Pokemon game in the future.
