I really wouldn't worry about it too much. One of the latest google updates is now checking for "over optimisation", so if you have a spammy url segment like "this-is-my-product-it-is-red" you could start flags waving in googles ranking algo. If it was JUST that you should be fine, but if you have your product name multiple times in your text content, navigation, image alt text, title text, css class names, etc, you could be in for a rough ride.
