Looking for Magenta Dyes
Does anyone know of any suppliers that make a magenta or pink dye, that is safe to use on skin products. FD&C Red #3 is now banned. D&C Red #33 is not magenta/pink enough. I am having a problem with making bright purple shades. Any help would be great.

I am currently experimenting with D&C Violet 2 EXT, but its solubility in water is not so great. I would make 0.002 g/ml solution of D&C Violet Pigments in water. Even after hours of mixing you can still see lots of agglomerates of the pigment at the bottom of my beaker. I'd pipette the top layer of this solution which shouldn't have agglomerates, to a desired amount into my sugar scrub base. The sugar scrub is mostly glycerin. After a day of letting it set you can see specks of what i presume would re-agglomerate of pigments forming spots in the product.
I tried quick experimental mixtures with the red 30 lake with blue #1 or Violet 2. The color I needed worked for Violet # 2.
1 issue I had with this is that breaking down the red 30 lake pigments was very difficult. I don't really work with lakes, but I guess you normally have to mill lakes to even disperse them? I thought maybe if I had place the red 30 lake pigments directly into the sugar scrub the sugar will grind down the lake itself through mixing ~ it worked. However, I don't have the means to do this if I were to put this color mixture into a lotion.
2. Violet #2 still re-agglomerates.
This would all save me so much time if a pink dye exist
@ozgirl I have not. It seems like this is designed for food usage. Is this okay in cosmetics?
