Description

EXAMPLES

[0027] The examples are provided to illustrate the invention, but not to limit it.

Example 1

[0028] Hydrogenated polyisobutene and isododecane were mixed in a vessel until homogeneity was reached. In a next step, the Dow Corning DC FA 4002 ID copolymer was added for the inventive example, then the ethylene/propylene/styrene copolymer was added and the mixture was stirred until homogeneity was reached. In a final step fragrance was added.

[0029] Split end damaged human hair streaks from Caucasian donors were analysed on their hair split ends extend by light microscopy with a 10 to 20 magnification. 10 hair fibres from each hair streak were analysed. The hair length was between 3 and 5 cm per fibre. The hair was treated with the compositions and the immediate effect was measured by light microscopy and expressed as a ratio of hair with closed ends to the total number of hair fibers by the following equation:

[00001]$\mathrm{Hair}.Math..Math.\mathrm{split}.Math..Math.\mathrm{ratio}\left[\%\right]=\frac{\mathrm{Number}.Math..Math.\mathrm{of}.Math..Math.\mathrm{hair}.Math..Math.\mathrm{fibers}.Math..Math.\mathrm{with}.Math..Math.\mathrm{closed}.Math..Math.\mathrm{ends}}{\mathrm{Total}.Math..Math.\mathrm{number}.Math..Math.\mathrm{of}.Math..Math.\mathrm{hair}.Math..Math.\mathrm{fibers}}.Math.100.Math.\%$

[0030] Then the hair was rinsed and shampooed once with Goldwell Dualsenses Scalp Specialist Deep Cleansing Shampoo, analyzed again, and then shampooed for 4 more times. After air-drying the hair, the hair was analyzed by light microscopy and the same calculations from above were performed.

[0031] As a result, hair treated with the inventive composition had a high recovery rate from split ends. Moreover, the effect sustained after rinsing with water and shampooing. Consequently the inventive composition had a beneficial effect superior to the comparative example.

[0032] Similar results were observed with the following examples. The preparation of the compositions as well as the effect analysis were performed as outlined above.
