They're synthetic but the way the hairs are cut make this brush great for powders AND creams/liquids.

I don't actually know! But, this brush is incredibly soft, washes beautifully, and holds up well. I've had mine for over a year and it's just like it was when I purchased it. I have sensitive skin, and I've never had a problem with it.
