cosmocil cq has recently received world-wide approval and is now available here at old time soap company. This new preservative is parabens free and does not release formaldehyde. Like phenonip, cosmocil cq can be used at higher temperatures -- up to 284°f (140°c), but unlike phenonip, it is low-odor so you won't have to deal with camouflaging the smell. Unfortunately, cosmocil cq is only water soluble (add to the water phase), so unlike phenonip, it's not miscible in oil and can't be used in an all-oil produce (e.g. salt/sugar scrubs). the usage rate ranges from .5% to 1.5%, with the typical usage rate being 1% of your total formula.
