Carbon black is a pigment which is a color and mainly used in the tire making business.That chemist isnt gonna tell you much of anything these soap formulas are not cheap.Most of these so called chemist are selling rebaged chemicals not really blending there on.When we talked on the phone once you told me that you had to go back and rebrighten the aluminum if that brown stuff stayed on to long.However if your are gonna dye a fleet wash product use fabric dye.Food coloring doesnt hold up as well as the fabric dye.Clear would be a good color that way you could tell how well the soap was blended with the couplers and binding agents and corosive inhibiters.
