Abstract

A method of assessing perfume on hair comprising the following steps: a) first treating the hair with a composition comprising an encapsulated perfume; b) contacting the hair with a textile item; 5 c) removing and sniffing the textile item; and d) using the fragrance on the textile item to determine the fragrance of the hair.

Claims

1. A method of assessing perfume on hair comprising the following steps: a) first treating the hair with a composition comprising an encapsulated perfume; b) contacting the hair with a textile item from 1 hour to 12 hours; c) removing and assessing the fragrance on the textile item; and d) using the fragrance on the textile item, as determined in step (c), as an indication of the fragrance of the hair.

2. The method of claim 1, wherein the textile item is selected from a scarf, veil, helmet, hijab, hat, cap, wig and turban.

3. The method according to claim 1, wherein the composition is selected from a rinse off, leave-on and spray.

4. The method according to claim 3, wherein the composition is selected from a shampoo, conditioner, styling product, fragrancing product, detangling product and treatment product.

5. The method according to claim 1, wherein the hair composition further comprises a non-encapsulated perfume.

6. The method according to claim 1, wherein the encap releases its perfume by diffusion from the encap or by mechanical shear.

7. The method according to claim 1, wherein a secondary textile piece is worn on the hair.

8. The method according to claim 1, wherein the textile item is worn for from 1 minute to 12 hours, preferably up to 8 hours.

9. The method according to claim 1, wherein step (d) is carried out when the hair is dry.

10. The method according to claim 1, wherein the assessing of the fragrance on the textile item is done by sniffing the textile item by the wearer.

11. The method according to claim 1, wherein the fragrance indicated on the hair is correlated to a scale, preferably from strong pleasant odour to weak pleasant odour to absence of odour to weak malodour to strong malodour.

Description

EXAMPLES

Example 1: Treatment of Hair in Accordance with the Method of the Invention

[0169] Mannequin heads with shoulder length brown Caucasian hair were washed thoroughly with unscented shampoo and then rinsed. The process was then repeated until the natural hair odour was not detectable, or until any previous odours on the hair had been removed.

[0170] 10 ml of a shampoo (SH1) containing fragrance capsules was applied onto the crown of the wet mannequin head. The hair was lathered for 1 minute and then rinsed for 2 minutes until there was no shampoo left on the head. The process was then repeated a second time.

[0171] The mannequin heads were then very lightly towel dried to remove the bulk of the water. The heads were left to air dry naturally overnight in a well ventilated room. When the hair was dry, the head was dressed with a Hijab, consisting of a tight fitting cap and covered a headscarf.

Example 2: Assessment of Fragrance

[0172] A fragrance intensity assessment was carried by a trained fragrance expert. The intensity was scored on a scale from 0 to 10, 0 meaning no fragrance detectable and 10 a very strong fragrance.

[0173] A 0 hours, the Hijab was removed to allow for fragrance assessment. The hair and inner tight fitting cap (textile) were both assessed and the intensity scores at various times are given in Table 1 below.

TABLE-US-00001 TABLE 1 Fragrance intensity for hair and textile covering after 0-7.5 hours Time (hours) 0 2 4 6 7.5 SH1 - hair 6 6 7 6 6 SH1 - textile 5 6 6 6 5

[0174] It will be seen that close correlation between the fragrance intensity of the hair and that of the Hijab was achieved by the method of the invention.
