Description

B 10-5135EN 1 Process for treating keratinous fibers using an elastomeric silicone in combination with heat. The present invention relates to a process for treating keratinous fibers, in particular human keratinous fibers, such as hair, using a composition comprising one or more elastomeric silicone (s) in combination with heat. In particular, the subject of the invention is a process for shaping keratinous fibers, in particular for curling, curling, straightening, smoothing and disciplining keratin fibers, using a composition comprising one or more elastomeric silicone (s). ) in combination with heat. Hair straightening, smoothing or permanent chemical treatments have long been used to obtain a lasting deformation of keratinous fibers. The hair keeps their shaping after several shampoos. However, the use of these treatments induces in the long run the deterioration of the quality of the hair fiber. These chemical treatments have the disadvantage of damaging and weakening the hair fiber by causing the disulfide covalent bonding of keratin to rupture. For example, a decrease in the cosmetic properties such as gloss and degradation of the mechanical properties, more particularly a degradation of the mechanical strength of the hair fiber (swelling of the more porous hair) is observed. The hair is weakened and can become brittle during subsequent treatments such as brushings. This problem is aggravated when these treatments are applied to sensitized keratin fibers (E. fragilisés). This sensitization may result from the action of external atmospheric agents such as light and weather, and mechanical or chemical treatments such as brushing, combing, dyeing, discoloration, perms and / or straightening. In addition, these chemical treatments are often accompanied by unpleasant odors.

As a result, many people with curly hair, curly hair or rebellious hair want to permanently smooth their hair without using hair straightening products or chemical smoothing. Similarly, many people with smooth hair want to obtain loops that hold in time, without resorting to a chemical perm. Hair care fixing rinsed are not always sufficient to obtain a lasting shaping. Similarly, the use of heating shaping devices such as curling irons, smoothing or curling, or hair also does not give complete satisfaction. When hairstyles are wet or exposed to high humidity, the hair loses its shape and tends to quickly return to their original shape. Some hair care not rinsed to provide smoothing and maintenance of the hair, may also have the disadvantage of bringing a particular hard or hard touch. Therefore, there is a need to implement products, rinsed or not rinsed, which facilitate and improve hair shaping, including smoothing or loop creation, in a sustainable manner, without chemical alteration and without leading to a hardening or a greasy touch of the hair fiber. Surprisingly and advantageously, the Applicant has discovered that the use of one or more crosslinked elastomeric silicone (s), in combination with heat, provided these advantages. In particular, the Applicant has discovered that the use of one or more silicone (s) elastomer (s), allowed to form keratin fibers in an effective and durable manner especially in conditions of high relative humidity (at least 80% for example) or even after several washes, without chemical alteration of the hair fiber and without the aforementioned disadvantages. It has been observed that such an association makes it possible in particular to improve the shaping (the hair is smoother, the loops are more marked, better drawn), the ease of shaping and the holding of the shaping of the hair , regardless of its nature (Caucasian or European, Asian and African), compared to conventional non-elastomeric silicone hair treatment products, such as amodimethicone for example. The hairstyles obtained by implementing the method according to the invention take at least 24 hours even under high relative humidity conditions. The styling performances of smoothing or looping can thus persist for about a week. This can be done weekly to ensure a continuous effect. In addition, the keratinous fiber treatment method according to the invention is particularly advantageous for shaping sensitized keratinous fibers without these being more fragile or damaged and that the touch is impaired. Other objects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and examples which follow. According to the present invention, the process for treating keratinous fibers, in particular human keratinous fibers, such as hair, comprises a step of applying a composition comprising one or more elastomeric silicone (s) and at least one a simultaneous, prior or subsequent step of heat treatment of said keratinous fibers. Depending on the order of the steps, the heat treatment will therefore take place in the presence or absence of the composition on the keratinous fibers. Preferably, the composition comprising one or more elastomeric silicones according to the invention is first applied to the keratin fibers, and then these fibers are subjected to one or more heat treatments. During the heat treatment (s), the heat can be brought to the keratinous fibers by any well known heat source and usually used in the hair field. As a usable heat source, one can use for example one or more heating devices with thermal conduction, infrared radiation and / or thermal convection. The heat can thus be fed to the keratinous fibers by contact with the heating device (s) with the keratinous fibers, by infrared radiation and / or convection of hot air. During the heat treatment (s), the temperature of the keratinous fibers is raised to at least 40 ° C, and more preferably to at least 150 ° C.

Preferably, the process according to the invention is a process for shaping keratinous fibers, in particular human keratinous fibers, such as hair. The method according to the invention may then further comprise a step of shaping the keratinous fibers. This step may be distinct from the heat treatment stage or stages of the keratinous fibers or may be carried out simultaneously at a heat treatment stage. The shaping of the keratin fibers may be carried out by hand, for example by wrapping a lock of hair between the fingers to form a loop, or by means of one or more mechanical shaping devices, such as tweezers or curlers.

According to a preferred embodiment according to the invention, the step of shaping the keratinous fibers is carried out simultaneously with a heat treatment step. In this case, the heat treatment is carried out using one or more heat conductive heating device (s) capable (s) of heat-treating the keratinous fibers and of shaping them simultaneously. This is called heating shaping devices. When applying a heating shaping device to the keratinous fibers, the contact surface or surfaces of said device with the keratin fibers may be in various forms, depending on the shape of the desired deformation. The contact surface or surfaces may for example be flat (smoothing plates) to obtain a smoothing or round (curling iron) to obtain loops. It (s) can also take any form useful for creping, embossing, crimping or any desired original shape. Preferably, the heating device comprises two contact surfaces with the keratinous fibers. In this case, the two contact surfaces preferably have complementary forms, identical or different, superimposed on one another. It may be for example two flat surfaces or a surface having at least one concave portion and a surface having at least one convex portion. Preferably, a heating iron is used as a shaping iron or a curling iron possibly associated with a source of steam.

The application of iron can be done by successive separate keys of a few seconds, or by moving or sliding progressively along the locks of hair. When a heating shaping device is used, the contact surface of the heating device with the keratinous fibers has a temperature greater than or equal to 40 ° C., preferably ranging from 40 to 250 ° C., preferentially from 150 to 250 ° C, and more preferably 150 to 220 ° C. Preferably, the process of the invention is carried out with an iron with a temperature ranging from 150 to 250 ° C., and more preferably ranging from 150 to 220 ° C. The method according to the invention may further comprise one or more steps of rinsing, non-thermal drying, capping keratin fibers, for example using a comb or a hairbrush.

When the composition used according to the invention is a rinsed composition, the step of applying the composition to the keratinous fibers is followed, after a possible exposure time, with a rinsing step optionally followed by a drying step. and / or brushing keratin fibers, before thermal treatment of keratinous fibers. The duration of the exposure time can vary from 1 to 10 minutes, preferably from 2 to 5 minutes.

Sensory Analysis For each composition according to the invention, the procedure is as follows. The composition is applied at the rate of 10 g on a half-head. After a two-minute exposure time, the hair is rinsed and then pre-dried with a hair dryer. Then a flat clip heated to 210 ° C on the hair.

Results of the Sensory Analysis: It has been observed that the rinsed or non-rinsed compositions A to K according to the invention have good styling properties (discipline) and good cosmetic properties (smoothing). In addition, no curing effect of the hair usually related to styling polymers is observed. Similarly, no deterioration effect of the hair fiber usually associated with the durable chemical shaping treatment is observed. In particular, it was observed that composition B led to smoother and more disciplined hair compared to a composition of identical formula comprising an amodimethicone instead of elastomeric silicone. In addition, it has been observed an increased smoothing facility and increased discipline that lasts longer. These results were observed on Caucasian, Asian and European hair.

Image Analysis Compositions B and B 'were compared (B' being a comparative composition identical to Composition B, but comprising an amodimethicone instead of KSG 210 elastomeric silicone). 3 identical locks of 1 gram of naturally curly hair of Caucasian type, having previously undergone 2 discolorations (with the aid of the product sold under the name Platifiz), were applied to the same quantity of composition B or B 'and then the rinses were rinsed. hair.

The locks are then pre-dried in the helmet at a temperature of about 60 ° C for 10 minutes, then combed before being smoothed with a straightener at 210 ° C. The iron is applied 5 times. Image was evaluated by evaluating the contribution of discipline of each of compositions B and B 'tested, before treatment, just after treatment (to) and after 24 hours of exposure in an environment at 80% relative humidity. The lower the measured dispersion (misalignment), the more disciplining the product.

Results of the image analysis: Local dispersion (°) After treatment After 24 hours at 80% relative humidity Composition B '29 43 Composition B 32 34 Results after 24 hours of exposure to a high humidity environment show that the hair treated with the composition B have retained their disciplining effect, unlike the hair treated with the composition B '. Consequently, the composition according to the invention makes it possible to improve the disciplining effect (smoothing and ease of smoothing) of the hair over time under conditions of high relative humidity.
