Yes it lasts longer, the problem is the wick. Most wicks are made of cotton (if they are natural, DO NOT go with the lead or metal filled kind) and they burn faster than the soy base does. The other problem is the smell. Even with fragrance added, you can smell a strange ‘aftersmell’. However there is a huge market for soy candles and I would be glad to be part of your new enterprise. Mail me if you have questions, or are interested.

yes, soy candles burn cooler and cleaner. i use soy candles with essential oils for different purposes, for instance, lavender to help me sleep and eucalyptus to breathe easier. i will never go back to regular wax candles again.
