pretreating agent (a)

Reagent (a2)	(a2)
		Ammonia/citric acid	Adding to pH 9.5
Water (W)	100g

Colorant (b)

2. Applications of

To prepare ready-to-use pretreatment agent (a), the amounts of reagent (a1V) and (a1E) were mixed with the amount of reagent (a2) under shaking. Then, the reagent (a) was left for 15 minutes. The reagent (a) is a ready-to-use reagent.

A tress of hair (Kerling, european natural white hair) was immersed in the agent (a) and left for 1 minute. Then, the excess agent (a) is removed from each bundle of hair. Each hair tress was washed with water. Excess water is scraped from each bundle of hair.

Subsequently, the hair strands were each immersed in the agent (b) and left therein for 1 minute. Then, the excess agent (b) is removed from each bundle of hair. Each tress was then washed thoroughly with water (1 minute), dried and evaluated visually.

3. Measurement of Friction fastness

To determine crockfastness, each hair was combed 100 times using a comb with fine teeth. After that, each tress was again evaluated visually.
