Black Colorant for Cream/Serum (Non-Staining)

For making face and body creams or serums where you want a black color that does not stain the skin, it is recommended to use a water-soluble black colorant specifically designed to be easy to wash off.

Based on the product information, Black Color EasyWash™ is a suitable option. Its description explicitly states that it is a special type of water-soluble black color that does not stick to the surface and is easy to wash off.

Other general water-soluble black color powders may not be suitable for cream, lotion, gel, or serum formulations if you want to avoid staining, as they are not specifically formulated for easy wash-off in these types of products.
