Ingredients identical to Dr. Bronner's liquid soap, but price is double or higher [SEP] So, this product is natural and works well to clean brushes.  It is a super basic soap without unwanted chemicals, which is great.  However, the ingredients are pretty much identical to Dr. Bronner's Pure Castille Liquid Soap, which costs half as much or less, and does the exact same thing.  Dr. B's also comes in numerous scents (all organic) and even unscented.  Also, I think Dr. B's is more concentrated, so it takes less soap to clean each brush, making it even more economical.<br /><br />Bottom line, this "Makeup Brush Cleansing Shampoo" is a perfectly good product, but you can get essentially the same thing for a much lower price by buying Dr. Bronner's Liquid Soap instead.
