Protocol of Application

[0273] Swatches (27 cm) of Caucasian double-bleached hair were washed with a shampoo, rinsed and dried.

[0274] The compositions A and B thus obtained were then applied on the swatches according to a ratio of 3 g of composition per gram of hair. After 2 minutes, the swatches were dried.

Instrumental Evaluation

[0275] Characterisation of the surface state of dry hair was conducted through a sliding test using a sliding bench in a controlled environment (23? C., 50% HR). The test was repeated on three hair swatches for each composition.

[0276] A mobile swatch, attached to a sliding bench, was caused to move in a horizontal rectilinear manner between two other fixed swatches. The force needed to make the swatch to slide between the two others was measured with the aid of an electronic gauge linked to a driving arm. The measurement was made from roots to tips.

[0277] The average force (over 3 measurements) was calculated, and the evolution of the sliding force was recorded to quantify the surface state (homogeneous or not), along the fibre. The lower the sliding force, the more homogeneous the surface state of the hair. The more homogeneous the surface state, the smoother the hair to the touch.

[0278] The results are collated in the table 2 below:

TABLE-US-00002 TABLE 2 Average Standard Compositions Fmax (N) deviation (N) A (invention) 0.77 ?0.01 B (comparative) 1.02 ?0.02

[0279] The sliding force for composition A according to the invention is significantly lower than the sliding force for comparative composition B. Thus, the surface state is more homogeneous and the hair is smoother to the touch when treated with composition A according to the invention.

[0280] Composition A possesses good usage properties: indeed, it is a translucent composition, which has a singular, pleasant texture when applied.

[0281] The hair treated with composition A is smooth, shiny, straight, detangled and easy to style.

[0282] Moreover, composition A possesses adequate viscosity to be delivered with a dropper device in a controlled and cost-saving manner.

Example 2

[0283] Composition C according to the invention was prepared from the ingredients indicated in the table 3 below, the amounts of which are expressed in grams of AM per 100 g, unless otherwise mentioned (AM meaning active material):

Protocol of Application

[0284] Swatches (27 cm) of Caucasian double-bleached hair were washed with a shampoo, rinsed and dried.

[0285] The composition C thus obtained was applied on the swatches according to a ratio of 3 g of composition per gram of hair. After 2 minutes, the swatches were dried.

[0286] The dropper device was used to deliver composition C.

Results

[0287] Composition C possesses good usage properties: indeed, it is a translucent to transparent composition, which has a singular, pleasant texture when applied.

[0288] The hair treated with composition C is smooth, shiny, straight, detangled and easy to style.

[0289] Moreover, composition C possesses adequate viscosity to be delivered with a dropper device in a controlled and cost-saving manner.
