Examples

1. Preparation

The following formulations were prepared (all numbers are in weight% unless otherwise indicated)

Pretreating agent, reagent (a)	(a1)
		(3-aminopropyl) triethoxysilane	2.0
Methyltrimethoxysilane	7.0
		Ammonia/citric acid	Adding to pH 9.5
Water (W)	To 100 of

The silane was mixed with a portion of the water and the mixture was left for 30 minutes. The pH is then adjusted to the desired value by adding citric acid/ammonia. Then water was added to make up to 100 g.

2. Applications of

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 tress of hair was briefly 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 of hair was briefly washed with water. Excess water is scraped from each bundle of hair.

Thereafter, the hair strands are individually wetted with small amounts of the agent (c). The reagent (c) was allowed to act for 1 minute. The tresses were then rinsed with water and dried. The tresses were then visually evaluated. The perception of the dyed hair strands is also evaluated by specially trained personnel.
