22. The colouring composition of claim 2, comprising: a) 0.5 to 2 wt % of one or more dye compounds selected from Acid Yellow 23, Food Red 17, Acid Blue 9 and Acid Green 25; b) 1 to 4 wt % citric acid; c) 15 to 25 wt % propylene carbonate; d) 1 to 10 wt % ethanol and 1 to 10 wt % isopropanol; and e) 1 to 10 wt % urea and 5 to 15 wt % glycerol.

Description

EXAMPLE 1

[0225] Eyebrow colouring compositions were prepared comprising the components listed in table 1.

[0226] The compositions were contacted with European natural white hair for 10 minutes at 30° C. on foil open to the air before rinsing and drying.

[0227] The stability of the compositions was compared by observing the colour of the composition after 10 minutes, 2 hours and 3 days. The initial and desired colour was brown. The results are also shown in table 1.

EXAMPLE 2

[0228] Composition 5 of example 1 was applied to eyebrows using an angled brush. The form of the composition allowed it to be precisely applied, with a focus on areas of the brows that are missing brow hairs.

[0229] After 2 to 10 minutes (depending on depth required) the composition was wiped off the brows with a wet cotton wool pad or wipe. The eyebrows can then be shaped as required.

[0230] The result was excellent dyeing of the eyebrow without skin staining.
