RCMA apparently stands for Research Council of Makeup Artists, which the label further says was established in 1963. The packaging is very plain and reminds me of condiment shakers. I have nothing against plain packaging, but I do wish the holes were smaller to make dispensing less messy.

The product itself is white, but lends no pigment when applied, and no white cast, which is always a good thing. I am not sure how this would look on dark skin, but it disappeared on my NC25-30 skin after blending. It looks natural and does not have a flat matte finish. The powder is finely milled, somewhere in between Laura Mercier translucent powder and Ben Nye loose powder.

I wore this powder for 15 hours in 32-degree weather, on a day that I had forgotten to bring my powder compact. I did still get oily, but it was manageable with just two oil control films. There was no caking, and I had less creasing in my eye area than usual after such a long day. 

If you are looking for a colorless powder for setting and oil control, this is a good one to try. At 3 ounces for a bottle, this will last a long time since you don't need much per use.

I bought this for P850 at dtcmakeup.com, where I was very pleased by the customer service; my order arrived a day after payment!
