Description

  The present invention relates to a method for treating keratin fibers (such as hair) and compositions and kits used in the method.

  Because there is a lot of physical stress (UV, shampoo, brushing, etc.) and chemical stress (coloring, perm, relaxing, contamination, etc.) that keratin fibers (such as hair) must routinely receive Research into the effective repair of damaged keratin fibers has become important in the cosmetic treatment of keratin fibers.

  The repair of damaged keratin fibers is only valuable if you get a realistic sense that you have returned to the original keratin fibers. Furthermore, such a repair process should be effective against various stresses as described above.

  Previously proposed techniques (compositions and / or methods) for the treatment of repairing damaged keratin fibers are often temporary and the keratin fibers are in their original state. Speaking of not achieving the correct recovery, it is still inadequate.

  Sugars or sugars are known as cosmetic agents in cosmetics for keratin fibers. For example, see US-A-2007-226916.

  However, these cosmetic properties for keratin fibers are still insufficient due to their low deposition rate on keratin fibers or limited penetration into keratin fibers. This means that the efficiency of the cosmetic treatment of keratin fibers using saccharide is low, and a large amount of saccharide is required in the preparation used for the cosmetic treatment.

  Accordingly, the object of the present invention is to provide a saccharide or derivative thereof that has a good cosmetic effect, in particular an excellent repair or recovery effect, on keratin fibers and can be effective against various stresses over a long period of time. It is to provide a new treatment method for keratin fibers (hair etc.) used in a small amount.

The aforementioned object of the present invention is a method of treating keratin fibers, comprising:
Applying a composition comprising at least one saccharide or derivative thereof on the keratin fibers;
Then placing the keratin fibers in an enclosed space;
And then heating the keratin fibers.
The composition may also be a reducing agent of the formula:

(Where
X _{^{is, O -, OH, NH 2}} , O-OH and O-COO ^- is a group selected from the group consisting of)
This can also be achieved by a process that does not contain any source of carbonate ions.

  The aforementioned method may further comprise rinsing the keratin fibers after applying the composition onto the keratin fibers and / or after heating the keratin fibers.

  Mechanical tension may be applied to the keratin fibers. Mechanical tension may be provided by using at least one reshaping means selected from the group consisting of curlers, rollers, plates and irons.

  The enclosed space may be formed by at least one coating means. The coating means may be hard or soft. The coating means may include at least one member selected from the group consisting of a film and a sheet.

  In the foregoing method, during the step of heating the keratin fibers, the keratin fibers may be heated at 45 ° C to 250 ° C. The keratin fibers may be heated by at least one heater that supplies at least one selected from the group consisting of hot air, hot steam, high frequency induction heating, microwave heating, infrared irradiation, laser and flash lamp irradiation. The coating means and / or the reshaping means may comprise the heater.

  The saccharide can be selected from the group consisting of monosaccharides, oligosaccharides, polysaccharides and mixtures thereof. Monosaccharides or derivatives thereof are glucose, fructose, galactose, mannose, talose, sorbose, xylose, lyxose, fucose, arabinose, rhamnose, ribose, ribulose, xylulose, sorbitol, triose, pentose, hexose, ketose, glucosamine and mixtures thereof Can be selected from the group consisting of The oligosaccharide or derivative thereof can be selected from the group consisting of maltose, lactose, saccharose, cellobiose, trehalose, sucrose, fructo-oligosaccharide, dextrin and mixtures thereof.

  As a result of diligent research, the present inventors have used a composition containing a saccharide or a derivative thereof in combination with a specific heating method for keratin fibers to achieve a good cosmetic effect, in particular, various stresses over a long period of time. It has been discovered that it is possible to provide keratin fibers such as hair with an excellent repairing effect or an excellent recovery effect that can be effective against keratin fibers even when sugars or derivatives thereof are used.

  The specific heating method described above is performed in a closed or closed environment that limits the evaporation of water or moisture from the keratin fibers and maintains the keratin fibers at high temperatures, preferably in a moist state. Thereby, the keratin fibers can be heated evenly and the sugars or their derivatives can easily penetrate into or deposit on the keratin fibers, so even after some stress such as shampoo Alternatively, the derivative can remain in or on the keratin fibers for an extended period of time.

  Since saccharides or derivatives thereof can easily stay on or in keratin fibers, the method according to the present invention is compared to conventional methods where it is difficult for saccharides or derivatives thereof to stay on or in keratin fibers. Even in a relatively small amount, a good cosmetic effect can be exhibited by using saccharides or derivatives thereof.

  The composition used in the present invention should not contain a reducing agent such as a thiol compound. Therefore, malodor derived from the reducing agent can be prevented. Furthermore, the composition used in the present invention must not contain any carbonate ion source as defined above. Thus, cosmetic treatment is more effective because it does not produce carbon dioxide that forms bubbles that can inhibit the deposition or penetration of sugars or derivatives thereof on or into keratin fibers.

  The heating method can be performed by any heating means that can be freely controlled to achieve the desired temperature for the method.

  The heating method preferably forms an enclosed space to limit evaporation of volatile components (such as water) from the keratin fibers in the aforementioned composition and to maintain a predetermined temperature in the heating device throughout the method It may be implemented by using a special heating device that can.

  If evaporable components (such as water) in the aforementioned composition evaporate from the keratin fibers, it is believed that most of the thermal energy added to the keratin fibers will be consumed by evaporation, and therefore the temperature of the keratin fibers is The temperature cannot be increased to a predetermined temperature until all evaporable components in the composition are evaporated.

  The aforementioned heating device may comprise any thermal energy source in contact with or away from the keratin fibers and at least one means for forming an enclosed space surrounding the keratin fibers. Good.

  A thermal energy source is used to heat the keratin fibers. The thermal energy source may be at least one heater that supplies at least one selected from the group consisting of hot air, hot steam, high frequency induction heating, microwave heating, infrared irradiation, laser, and flash lamp irradiation.

  The enclosed space may be formed by at least one coating means. Multiple coating means may be used. The coating means may be hard or soft.

  According to the invention, the coating means may comprise a thermal energy source. Thus, for example, a film or sheet containing a heater may be set on a rod, bar or plate covered with keratin fibers.

  The occluded state can limit the evaporation of evaporable components (such as water) in the aforementioned composition applied to the keratin fibers, and therefore the temperature of the keratin fibers is a conventional method or apparatus for heating keratin fibers in the open state. The temperature can be raised higher than the temperature that can be obtained. Furthermore, keratin fibers can be effectively heated, and keratin fibers can be heated evenly.

  According to a variant of the invention, the enclosed space may comprise openings, whose surface area is less than 5%, preferably less than 3%, more particularly less than 0.5% of the total surface area of the coating means. According to this variant, the total surface area of the coating means comprises the surface area of the opening means (if present) for the coating means.

  The opening may be a passage, hole or hole, so that the air between the enclosed space and its exterior, especially when the reaction (such as forming vapor inside the enclosed space) is too great. It is thought that exchange will be possible. Conversely, a person skilled in the art can form the opening so that the diffusion of heat in the enclosed space is not hindered.

  The keratin fibers can be heated at 45 ° C to 250 ° C, preferably 60 ° C to 200 ° C, more preferably 60 ° C to 150 ° C, more preferably 60 ° C to 90 ° C during the step of heating the keratin fibers.

Mechanical tension can be applied to the keratin fibers by any means for transforming the keratin fibers into the intended shape. For example, the mechanical tension may be provided by at least one reshaping means selected from the group consisting of curlers, rollers, clips, plates and irons. The reshaping means may include at least one heater as described above. When keratin fibers are wound around the curler, this winding may be performed on the entire length of the keratin fibers or, for example, on half the length of the keratin fibers. For example, depending on the desired hairstyle shape and the amount of curl, winding may be performed in a somewhat thick bundle.

  Next, the aforementioned composition is applied to keratin fibers. The composition may be applied by any means such as a brush and a comb. Keratin fibers that have been subjected to mechanical tension should be treated with the composition. It is considered that the keratin fiber can be left as it is for a certain length of time if necessary.

  Finally, the above heating method is performed. Thermal energy is applied to the keratin fibers under occlusive conditions, as described above.

  This method for permanent deformation of keratin fibers can be performed without any step of oxidizing the keratin fibers. Thus, the time required for the method according to the invention can be shorter than the time required for a conventional method requiring an oxidation step. Furthermore, damage to the keratin fibers due to the oxidation step can be avoided.

  The keratin fibers may be rinsed after applying the composition onto the keratin fibers and / or after heating the keratin fibers.

One embodiment of a hair treatment method according to the present invention is a method for reshaping or permanently deforming keratin fibers, especially hair, comprising:

It can be controlled to be constant ± 2 or 3 ° C during heating. Thus, the hairstyle becomes uniform and homogeneous throughout the hair, and a better hairstyle can finally be obtained.

  Advantageously, the coating means may comprise one or more insulations, and more advantageously, the coating means may consist of such materials.

  The term “insulation” means any material having a thermal conductivity of 0 to 1 W / m ° C. (PVC: 0.17 W / m ° C.).

  Preferably, the heating means may be adjusted so that the temperature measured on the keratin fibers is 50 ° C. or more, more preferably 55 ° C. to less than 150 ° C., even more preferably less than 100 ° C. Heating is preferably performed by heating with electric resistance.

  Advantageously, the coating means is impermeable for the composition used in step b).

  In the foregoing embodiment, at least one of the reshaping means or the mechanical tensioning means and at least one of the cover means may include a heater.

  In the foregoing embodiment, the “enclosed space” is a closed structure (in which, when the coating means is placed on the reshaping means or the mechanical tensioning means (or vice versa), the means together. Heat can diffuse, but heat cannot diffuse out of the closed structure or is difficult to diffuse out of the structure). Preferably, the coating means and the reshaping means or the mechanical tension applying means can form a closed space when set on the head (when the keratin fibers are hair).

  The enclosed space is a condensation cage (in which water and components in the composition used in step b) can evaporate from the keratin fibers, adhere to the walls of the coating means and fall onto the keratin fibers ( condensation cage) may be formed. This cycle is believed to be repeated during the heating of the keratin fibers. In this way, the keratin fibers can always be kept moist, and drying and deterioration of the keratin fibers are prevented.

  Since the keratin fibers in the enclosed space can be kept moist and the temperature of the keratin fibers can be kept constant, the formation of the enclosed space is an important feature of the present invention.

  Preferably, the method of the present invention comprises the additional step of tightening the coating means on the individual's head (when the keratin fibers are hair) by means of a resilient cord, a stretchable band or a stretch material. Steps may be included.

  According to the method of the present invention, the amount of cosmetic ingredients in the composition is advantageously reduced compared to methods in the prior art because there is a closed space in which the composition can continuously set on keratin fibers. To do. The amount of cosmetic ingredients may be from 0.3% to 3% by weight of the composition.

  In a preferred embodiment, the coating means may be placed on each hair curler (when the keratin fibers are hair) as reshaping means or mechanical tensioning means. In other words, each of the hair curlers (when two or more hair curlers are used) may be individually covered by the coating means. It is advantageous to cover each hair curler as it can prevent the composition applied on the keratin fibers in step b) from leaking into the scalp.

  In another preferred embodiment, the coating means may cover all hair curlers (when using more than one hair curler). In other words, the coating means may cover the entire head (when the keratin fibers are hair).

  Advantageously, the enclosed space formed in step d) may be maintained during step e). In other words, the coating means may be removed only after step e) or after stopping the heating in step e).

  If desired, the composition may be applied to the keratin fibers before applying mechanical tension to the keratin fibers. The keratin fibers may optionally be before and / or after applying mechanical tension to the keratin fibers, before and / or after applying the aforementioned composition to the keratin fibers, and before and / or after heating the keratin fibers. It can be considered that it can be left as it is for a certain length of time.

  After the above step e), if necessary, the keratin fibers may be fixed by oxidation after removal from the coating means.
