I do like how it's paraben and formaldehyde-free and it was quite effective in my lotion, but I can't quite get over the scent. I will purchase again, but I think it will need more essential oil to overcome the scent.

I have sensitive skin, so I need to use non-irritating preservatives. This product is awesome. As a bonus, it doesn't have a smell that I have dealt with from other preservatives.
Note: some preservatives act more as a surfactant; this one will combine more as an oil.

I have not used this yet, but I will when I get the chance. It came packaged perfectly. I'm glad it does not have all the "yucky" stuff that the other preservatives do.
