Surfactants are molecules with a hydrophobic (water-repellent) end and a hydrophilic (water-loving) end. Microorganisms have limits to the pH level that they can grow in, just like they have limits with water availability. Although we dont have the exact concentration of salt and glycerin that was used in Jackies tests, we can see that salt and glycerin both can act as a natural preservative because they bind to the water in the recipe and reduce the available water for microbial growth (it should be noted that although the concentration of salt and glycerin reduced the water availability, it was not high enough reduce the aw below the limit for bacterial growth).
