These ingredients are blended and then agitated with an excess of sodium carbonate. The undissolved solids are removed by centrifuging.
The resultant product is a somewhat viscous liquid with an intense red color. All of the color disappears within a few minutes after the dressing is applied to the skin. The glycerin is beneficial to the skin and at the same time serves to intensify the red color of the solution.
