Magnesium stearate mixed with kalk?

[nanomania]

As most of them know that Magnesium stearate is an anti caking agent, can it be mixed with kalk and dosed? So that way we can have cal alk and mag be added. Would that work? As raw kalk hardens easily, im sure that many branded cos. might be adding some anti caking agent.

Magnesium stearate is quite insoluble in water. That's a deal breaker when it comes to dosing.

Any magnesium is not OK since it will precipitate as magnesium hydroxide if it did try to dissolve.

So what anti caking agent is good with kalk?

Not sure what you mean. I never had problems with it caking when dry. Do you?

Are you storing it in an airtight container? My kalk stays powdery in the container that BRS ships it in. I always put the top back on and tighten it up. What kind of kalk are you using?

Plain raw calcium hydroxide.. i guess the branded and and even brs are using some sort of anti caking agen..
