SemiColor - Red Brown in Shampoo Formulas
Regarding the use of SemiColor - Red Brown (Basic Brown 16) in a shampoo formula and whether it will stain your hands, the product description provides guidance on this.
Using SemiColor at a high concentration can indeed cause staining. The recommended usage rate is 1%, and the FDA limit is 12%. If you use the product at a rate that is too high (exceeding these recommendations), it is indicated that staining will occur.
Therefore, to minimize the risk of staining your hands, it is important to adhere to the recommended usage rate of 1% in your shampoo formulation.
