We now offer Cosmocil CQ which is a paraben free preservative which won't release formaldehyde into your finished product. It holds a minimal scent, is low risk for skin and eye irritation, and has been proven to show no negative side effects on the human reproductive system. Yet Cosmocil CQ still holds a punch against gram negative pathogens, bacteria, yeast, and fungi even in high risk products like mascara's. This product is soluble in water, glycerin, alcohol and propylene glycol, and very easy to use. Usage rate is 0.2 - 1.5%.
PLEASE NOTE: this preservative cannot be used in beeswax-borax emulsion systems nor in natural liquid soaps. It will harden, and become gooey brown. It also appears to be incompatible with our SCG wax.
