Abstract

A method of colouring an eyebrow, the method comprising: (i) contacting the eyebrow with a colouring composition comprising: (a) a dye compound; (b) an organic acid; and (c) an aromatic compound.

Claims

1. A method of colouring an eyebrow, the method comprising: (i) contacting the eyebrow with a colouring composition comprising: (a) 0.1 to 5 wt % of one or more dye compound containing at least one sulfonate group, at least one carboxylate group, or both; (b) 0.1 to 5 wt % citric acid; (c) 5 to 10 wt % benzyl alcohol; and (d) 10 to 30 wt % ethanol, wherein the colouring composition stains the hairs of an eyebrow and the skin therebetween and the colouring composition is an aqueous composition comprising at least 60 wt % water.

2. A method according to claim 1 wherein the one or more dye compound is water soluble.

3. A method according to claim 1 wherein the colouring composition has a pH of 2 to 5.

4. A method according to claim 1 wherein the colouring composition further comprises urea.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1A shows eyebrows prior to treatment according to the present invention;

(2) FIG. 1B shows the same eyebrows after treatment;

(3) FIG. 2A shows the eyebrow of a first user before treatment;

(4) FIG. 2B shows the eyebrow of the first user after treatment;

(5) FIG. 3A shows the eyebrow of a second user before treatment; and

(6) FIG. 3B shows the eyebrow of the second user after treatment.

(7) The invention will now be further described with reference to the following non-limiting examples:

EXAMPLE 1

(8) An eyebrow colouring composition was prepared comprising the following components:

(9) TABLE-US-00001 Composition Ingredient (wt %) CI Acid black 1 1 CI Acid orange 7 CI Acid red 33 Ethanol 20 Lactic acid 4.0 Benzyl alcohol 10 Tylose 1.5 Sodium hydroxide to pH 3.5 Water balance

(10) To prepare the composition water was heated to 55 to 65° C. and tylose was added and stirred until a smooth gel had formed.

(11) After allowing to cool to room temperature, lactic acid, ethanol and benzyl alcohol were added and the mixture was stirred well.

(12) The dyes were added and the mixture stirred for at least 1 hour until the dyes had dispersed evenly.

(13) The pH of the composition was adjusted to 3.5 by the addition of sodium hydroxide.

EXAMPLE 2

(14) The composition of example 1 is 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.

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

(16) FIG. 1A shows eyebrows prior to treatment according to the present invention. FIG. 2A shows the same eyebrows after treatment.

EXAMPLE 3

(17) An eyebrow colouring composition was prepared comprising the following components:

(18) TABLE-US-00002 Composition Ingredient Wt % Acid Green 25 1 Acid Violet 43 Acid Red 14 Acid Yellow 3 Food Yellow 3 benzyl alcohol 7.5 ethanol 20 citric acid 2 phenoxyethanol 0.7 tylose 1.2 Heliogel (RTM) 0.5 Sodium hydroxide to pH 3.5 Water balance

EXAMPLE 4

(19) The composition of example 3 was applied to the eyebrow as described in example 2.

(20) FIG. 2A shows the eyebrow of a first user before the treatment, FIG. 2B shows the eyebrow of the first user after treatment.

(21) FIG. 3A shows the eyebrow of a second user before the treatment, FIG. 3B shows the eyebrow of the second user after treatment.
