As we all know the use of preservatives always causes discussion, but one thing is for sure, when you use water in products, it is important to add Preservatives to stop the growth of micro-organisms such as fungi and bacteria.
Please see the Natural Skin Care Library (top right on top menu) and then look under 'Quick Links' for Kolbjorn's current Preservative Guidelines and News.
Our range of Preservatives will increase the shelf life of your products - so that you can make natural and professional products! For example, the shelf life of Creams without any Preservatives is 1-2 weeks if stored in the fridge - this can be prolonged to 1.5-2 years by adding Preservatives (depending on the conditions of storage).
Many talk about using vitamins as preservatives but this is wrong; vitamins are antioxidants that stop products from going rancid but they don't affect and stop the growth of bacteria and fungi.
