Description

Title of the invention: KERATIN FIBER REVITALIZATION COMPOSITION technical field

[0001] The present invention relates to a cosmetic composition and its use. In particular, the present invention relates to a keratin fiber revitalization composition. The present invention also relates to a method for revitalizing keratin fibers. STATE OF THE TECHNOLOGY

[0002] Keratin fibers, particularly hair, tend to lose some of their qualities under the influence of various factors such as natural re-oiling, perspiration, shedding of dander, pollution, or humidity. The visual appearance and feel of the fibers can be degraded. Re-oiling, for example, makes the fibers dull, which then tend to clump together. The hair can then be more difficult to style and have an unpleasant greasy shine and / or waxy feel.

[0003] It is common to use detergent cosmetic compositions such as shampoos to wash keratin fibers, such as hair. These compositions are generally applied to the keratin fibers, which are preferably wet, and the lather generated by massaging or rubbing with the hands or a washcloth allows, after rinsing with water, the removal of the various types of dirt initially present on the hair.

[0004] In fact, consumers are looking for revitalizing compositions that have enhanced cosmetic and revitalizing properties.

[0005] However, many formulations on the market cannot form a uniform coating on the hair.

[0006] Some formulations may also not be entirely satisfactory in terms of cosmetic performance, particularly softness and smooth texture of hair.

[0007] Thus, there is still a need for keratin fiber revitalizing products, which can coat the hair evenly from root to tip and / or make the hair smooth and / or soft. Summary of the invention

[0008] An object of the present invention is therefore to develop a revitalizing composition of keratin fibers, which can coat the hair uniformly from root to tip and / or make the hair smooth and / or soft.

[0009] Thus, according to the first aspect, the present invention proposes a composition, preferably for revitalizing keratin fibers, comprising: a. at least one C-glycoside; b. at least one seaweed extract; and c. at least one oil.

[0010] The inventors discovered that after application to the hair, the composition according to the present invention gives the hair a good level of care, in particular a uniform coating from root to tip, and makes the hair smooth and soft.

[0011] According to a second aspect, the present invention proposes a method for revitalizing keratin fibers comprising the application of the composition according to the present invention on the keratin fibers.

Assessment Coating, smooth texture and softness

[0164] The coating on the hair, the smooth texture and the softness of the hair delivered by each composition prepared above were evaluated as follows: 1. Invitation of 6 fully trained sensory experts to participate in the trial. The experts were well-trained in the sensory evaluation of conditioners, representing over 50 different types of conditioners with varying performance levels. They are able to rate the performance of each control point (such as coating, smoothness, softness, etc.) on a scale of 0 to 5, where 0 represents the lowest performance for the corresponding control point and 5 represents the highest performance for the corresponding control point. 2. Instruction given to the experts to use each composition of inventive examples 1 to 4 and comparative examples 1 to 3 by following the steps below:

[0165] - Wash the entire head of hair with 12 g of shampoo and rinse thoroughly shampoo;

[0166] - application of 12 g of the test composition to the entire head of hair and to the scalp;

[0167] - massage and pose for 10 minutes;

[0168] - rinsing of the test composition;

[0169] - blowing on the hair to dry it completely; 1. Then, after coating the hair, the smooth texture and softness of the hair delivered by each composition were noted by sensory experts according to the training standard and the average of the scores was calculated for each composition.

[0170] The results on coating, smooth texture and softness of hair delivered by the compositions of inventive examples 1 to 4 and comparative examples 1 to 3 have been summarized in Table 3.

[0171] [Tables3] Properties ELI EL 2 EL 3 EL4 EC.1 EC.2 EC. 3 Coating 4.0 3.9 3.8 4.5 2.3 2.2 2.8 Smooth texture 4.1 4.0 4.0 4.5 2.5 2.5 3.0 Softness 4.2 3.9 3.8 4.5 2.4 2.6 3.1

[0172] It can be seen from Table 3 that each composition of inventive examples 1 to 4 can coat the hair well and give the hair a good smooth texture and good softness.
