Examples

1. Formulations

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

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 100 g.

2. Administration of

A lock of hair (Kerling, natural hair white in europe) was dipped into the agent (a) and left there for 1 minute. Thereafter, excess agent (a) is removed from each lock of hair. Each lock of hair was briefly washed with water. Excess water is wiped from each lock of hair.

Subsequently, the tresses were each immersed in the agent (b) and left there for 1 minute. Thereafter, excess agent (b) is removed from each lock of hair. Each lock of hair was briefly washed with water. Excess water is wiped from each lock of hair.

Subsequently, the tresses were evaluated visually. A whitish metallic colouring of the hair with high strength and fastness is obtained.
