DEEP COLOR H7 is an auxiliary agent that promotes the penetration and dispersion of the dyestuff during dyeing operation.
DEEP COLOR H7 uses the synergy of several amines, by this way being effective in a wide range of Ph and temperatures.
Thanks to its excellent features of retarding and levelling, it allows to obtain a very good dyeing levelling.
The suggested use percentages vary from 0.5%, in case DEEP COLOR H7 is used as a leveller, to 2% when it is used as a penetrating agent
