EXAMPLES

Example 1

[0238] The cosmetic compositions (A) and (B) according to the invention are prepared from the ingredients shown in the tables below, the amounts of which are expressed as weight percentages of active material (AM).

TABLE-US-00001 Composition A Jojoba oil 8.5 (Simmondsia chinensis seed oil) Dodecane 12.5 Polyquaternium-67 0.2 Polyglyceryl-3 diisostearate 3 Ethanol 30 Water qs 100 Composition B Jojoba oil 8.5 (Simmondsia chinensis seed oil) Dodecane 12.5 Xanthan gum 0.075 Scleroglucan gum 0.225 Polyglyceryl-3 diisostearate 3 Oleyl alcohol 1 Propylene glycol 5 Ethanol 25 Water qs 100

[0239] Compositions (A) and (B) according to the invention were each applied to locks of sensitized hair of Caucasian type (SA20), at a rate of 0.075 g of composition per gram of hair.

[0240] A sensory evaluation of the disentangling of the hair, of the cleanliness of the hair, of the smooth feel and smooth look, and of the sheen is then performed by three experts on each of the non-rinsed locks.

[0241] At T.sub.0, it is observed that the locks of hair treated with one of the compositions (A) or (B) according to the invention have a good level of care/conditioning, notably in terms of the disentangling, sheen, cleanliness, smooth feel and smooth look of the hair.

Example 2

[0242] The cosmetic compositions (C) and (D) are prepared from the ingredients shown in the tables below, the amounts of which are expressed as weight percentages of active material (AM).

TABLE-US-00002 Composition C Composition D (Comparative) (Invention) Jojoba oil 2.5 3.5 (Simmondsia chinensis seed oil) Dodecane 1.5 2.5 Polyquaternium-67 0.2 0.2 Polyglyceryl-3 diisostearate 3 3 Ethanol 30 30 Water qs 100 qs 100 Sum of the total content of plant 4 6 oil(s) and of the total content of hydrocarbon-based oil(s)

[0243] Compositions (C) and (D) were each applied to locks of sensitized hair of Caucasian type (SA20), at a rate of 0.042 g of composition per lock of hair of 2.7 g.

[0244] The compositions were distributed homogeneously from the roots to the ends of the hair.

[0245] The locks of hair were then dried for 15 minutes in the open air.

[0246] A sensory evaluation of the smooth feel and of the lightness is then performed on dry hair by six experts, in a blind test, on each of the non-rinsed locks.

[0247] The experts evaluated using a rating scale ranging from 0 (very poor) to 5 (very good). The rating scale varies in steps of 0.5.

[0248] To evaluate the smooth feel, the expert grasps the lock between the thumb and forefinger, and slides his fingers along the lock from the roots to the ends. He evaluates whether the hair is soft, if it does not have any roughness, if it does not hold the fingers, if the touch is homogeneous.

[0249] To evaluate the lightness, the expert lifts the hair in large strands with the hands and looks at the way the hair falls: the light hair is individualized, flowing and does not fall out in clumps.

[0250] The results are summarized in the tables below:

TABLE-US-00003 Composition C Composition D LIGHTNESS (Comparative) (Invention) Expert 1 2 4 Expert 2 2 4 Expert 3 2 4 Expert 4 3 4 Expert 5 2 4 Expert 6 3.5 3 Average 2.4 3.8 Standard deviations 0.7 0.4

[0251] It is observed that the locks of hair treated with the composition (D) according to the invention are lighter and smoother than the locks of hair treated with the comparative composition (C).
