Zero Xeno incorporates the use of a natural fermented based preservative system for our organic personal care productsFermenting coconut oil with Lactobacillus bacteria produces an effective and multi-functional product that provides preservative protection and moisturizing benefits. 
Lactobacillus bacteria are one of the species of microorganisms used to produce fermented products such as sauerkraut and kimchi, a Korean dietary staple from cabbage. Like many members of the lactic acid bacteria family, Lactobacillus are capable of restricting the growth of other microorganisms by acidifying its environment. 
The friendly bacteria also produce novel antimicrobial peptides, also known as bacteriocins, that are capable of providing broad spectrum antimicrobial and antifungal protection. These amazing little peptides are made from amino acids which is why they're famous for anti-aging and supreme moisturization!
We choose to use cold pressed, virgin organic olive oil, coconut oil, Shea Butter and coco butter in our products. When natural cold pressed methods of extraction are used to press oils, their level of anti-oxidants are higher than when chemical extraction processes are used. These naturally retained plant based antioxidants help to preserve our oils and allow us to produce high quality products that are effective and healthy.
