I love Brambleberry! We all have smelled scents that we don't like (I don't like anything with an almond smell, smells very fake to my nose) but brambleberry has great products and great customer service as well.
Anything with water in it will need a persertive. If your formula has only oils you may not need one. That being said, if there is a possibility of water being introduced into the product (wet hands), or If I plan to sell it then I would use a presertive.
I've been making soap (mp) and other bath & body products for about 5 or 6 years. My newest obsession is making mineral eyeshadow. I look forward to being a member of this forum and getting to know everyone.
