Crafter's Choice™ Gluconolactone & Sodium Benzoate Blend offers formulators of personal care products broad spectrum protection in a variety of cosmetic and personal care formulations. The blend of Gluconolactone and Sodium Benzoate is an effective alternative to the typical preservatives. The main ingredient, Gluconolactone, is a naturally occurring, gluten-free fermented food starch often used in the cosmetic industry as a moisturizer and chelating agent. Sodium benzoate is a preservative with the added benefit of inhibiting fungus growth under acidic conditions (pH should be 6 or below).
