Don't overthink your on-page, product-specific content. You're not going to get whacked by Panda just because you have a lot of content about a lot of similar products. Just make sure each product description is informative, well-written, maybe a little humorous, and above all original.
Sites that were hit hard by Panda were using mass-generated low-quality content targeted towards trending keywords in order to make money via AdWords and affiliates. Some kind-of-similar-but-original product descriptions were not part of the problem and were not targeted by Panda.
To your main question, you can always write interesting content, no matter how boring the subject.
Take a step back from your products for a second and brainstorm some broader categories that are loosely associated with your niche. Next, brainstorm some catchy, interesting article titles that still reference your products but are about those bigger categories with more mass appeal.
For instance, I write content for a restaurant equipment parts company. Not the most exciting topic on the planet, but I've had success by tracking trends in the restaurant industry like Groupon and mislabeled seafood and then written an interesting article about those topics. I figure out a way to work my company into the article and then put it out there to gain links back to my site.
The good news is since it's such a niche market there's not a lot of competition for the keywords I want to rank for and it only takes a few quality links from an article to get rankings up.
Combine some quality on-page content (without worrying too much about duplication - as long as a decently paid human writes each description you'll be fine) with some compelling articles about topics loosely associated with your products and you should see some improvement in your organic performance.
