Description

EXAMPLES

[0211] The compositions A and B according to the invention containing the ingredients hereunder were prepared, with all amounts expressed by percentages by weight of active matter with regard to the total weight of each composition.

[0212] Composition A (Invention):

TABLE-US-00001 Ingredients Amounts CAPRYLIC/CAPRIC TRIGLYCERIDE 20.0 BETA-CAROTENE (C.I. 75130) 0.008 D&C VIOLET 2 (C.I. 60725) 0.006 DIMETHICONOL 5.88 FRAGRANCE 0.4 CYCLOPENTASILOXANE Qs 100

[0213] Composition B (Invention):

TABLE-US-00002 Ingredients Amounts CAPRYLIC/CAPRIC TRIGLYCERIDE 20.0 BETA-CAROTENE (C.I. 75130) 0.008 D&C VIOLET 2 (C.I. 60725) 0.006 DIMETHICONE 8 DIMETHICONOL 6 FRAGRANCE 0.4 ISODODECANE Qs 100

[0214] 0.4 grams of composition A and B were applied, respectively to a 1 gram lock of Asian bleached hair sensitized (SA 20).

[0215] The locks were gently massaged from the root to the tip about 6 times between two fingers for 15 seconds.

[0216] It is observed that the locks treated with one of the composition A or B according to the invention are easier to detangle and present a better colour uptake, more shine, more smooth, and less frizz, than a lock of untreated hair.

[0217] In addition, the locks treated with one of the composition A or B according to the invention do not leave stains on the hands, nor on the skin.
