[0065] Example of Use of the Composition According to the Invention

[0066] The composition used in this example is a composition in a spray bottle containing propellant gas.

[0067] Stir the bottle which further contains a glass ball to ensure perfect homogeneity of the composition. Maintain vertically said bottle, head up and vaporize the composition of the invention at 20 cm from hairafter drying and/or brushing-, where the roots are visible, depending on the hairstyle. One proceeds by pressing and moving the bottle according to a hair line. On a spike, a couple of quick pressure is enough. If the hair is raised, pulled back, forming a bun or ponytail, small sprays is done along the edge of the hair, all around the head. Allow drying (drying time: 1 minute).

[0068] The composition according to the invention can be used to cover gray hair but also a fun way on a few strands to create contrast, bring the matter to color, play darker roots to highlight blonde spikes, get a tie and dye effect.

[0069] Evaluation of the Skin Compatibility of the Composition According to the Invention After Single Application Under Semi-Occlusive Dressing for 48 Hours (Test Carried Out on 11 Adult Volunteers)

[0070] Irritation potential of the compositions listed in Tables I to IV above was determined on 10 volunteers. A single application of 160 L is carried out on the anterolateral surface of the arm. The skin zone is kept in contact with the composition for 48 hours using a semi-occlusive bandage.

[0071] The 10 volunteers, male or female, aged 18 to 65 have normal skin and skin free of evolving dermatological lesion. The clinical scoring is carried out half an hour after patch removal and takes into account erythema, edema, papules, vesicles and bubbles. Depending on their intensity, scoring ranges from 0 to 3. The sum of the scores divided by the number of subjects sets the index of average irritation (I.I.M) which classifies the test element according to the schedule below:

[0072] I.I.M.<0.20 Non irritating 0.20<I.I.M.<0.50 Slightly irritating 0.50<I.I.M.<2 Moderately irritating 2<I.I.M.<3 Very irritating

[0073] Results: The average irritation index (IIM) of the composition according to the invention obtained is 0, 0 which proves that the composition of the invention proves non-irritating even in direct contact with the skin for 48 hours.

[0074] Evaluation of the Drying Time of the Composition According to the Invention, the Time and Water Resistance of the Coloring

[0075] The following tests were performed on 20 women aged 18 to 70 with long or medium length hair, colored dark brown, brown or black with white or blonde roots.

[0076] According to the hair color, the composition of the invention described in one of the above tables was sprayed at a distance of 20 cm, on the roots visible at the parting of hair.

[0077] a) Evaluation of the Long-Lasting Effect, i.e. 8 Hours After Application of the Composition According to the Invention.

[0078] Clinical assistant and volunteers evaluated the coloring of the product of the invention, obtained just after the drying of the composition, then 8 hours later. The coloring rating scale is graduated from 0 (no effect covering) to 9 (total coverage of the color of the roots)

[0079] The clinical assistant believes that right after applying the product of the invention, coloring rates average of 8.95 and 4.86, 8 hours later. The standard deviation is 0.22, respectively, and 1, 42.

[0080] Volunteers estimate that coloring (i.e. covering hair) appears immediately after application of the product is 7.48 and it drops to 4.24, 8 hours later. The standard deviation is respectively 1, 33 and 1, 45 for the two above average values. The clinical assistant esteem of the persistence % is equal to 54.26 and 56.69 to the volunteers.

[0081] The product according to the invention has good stability over time, is well tolerated and can be applied daily or twice daily.

[0082] b) Drying Time

[0083] Clinical assistant and volunteers evaluate the drying time by observing the disappearance of the effect of wet hair after applying the product of the invention. The drying time measured by the clinical assistant is 1 min 14 s. The drying time assessed by the volunteers is of 57 s. The composition according to the invention dries very quickly.

[0084] c) Water Resistance

[0085] The clinical assistant evaluates the water resistance by evaluating the coloring (covering effect) with the same scale as above immediately after application and after water spraying 15 minutes after application of the product according to the invention.

[0086] The clinical assistant believes that right after applying the product of the invention, the medium covering effect is 8.75 and 6.55, after water spraying 15 minutes later. The standard deviation is respectively 0.44 and 1, 15. The clinical assistant considers that the persistence % is equal to 74.86. The product of the invention thus is resistant to water, rain even shortly after application.
