Description

  The present invention relates to a method for permanent processing of hair easily and effectively, and a permanent kit useful for the permanent processing.

  Hair is mainly composed of keratin composed of 18 kinds of amino acids, and cysteine accounts for about 16% of the amino acids in keratin. The shape of the hair is mainly formed by fixing cysteine as cystine by disulfide bond. Permanent hair processing (wave or straight perm hair processing) treats hair with a perm solution (or treatment solution) containing a reducing agent to cleave or cleave disulfide bonds in keratin and apply tension with curlers, etc. Then, after forming a lot having a desired shape, an oxidizing agent is applied, and a disulfide bond between cysteines is again constructed and fixed. By such a method, the hair can be processed straight or curled.

  However, such a perm method is complicated in operation and the effect decreases with time, so that the temporary perm boom has also left, and in recent years the progress of the perm away has been urged. Under such circumstances, various developments have been attempted for perm liquids and perm methods. For example, in Japanese Patent Application Laid-Open No. 2004-2242 (Patent Document 1), in the process of permanent treatment using a first agent composition containing a reducing agent and a second agent composition containing an oxidizing agent with respect to straight perm, In the state where the hair structure is relaxed by the reductive cleavage of the disulfide bond in the inside, the organic acid having a specific structure is allowed to act, and the pH is adjusted to 1 to 5 using a buffering agent so that the hair is incorporated in a large amount. Compared to this method, a method has been proposed in which a straight perm having a high curly hair straightening effect and durability is possible by a simple shaping operation such as passing a comb. JP-A-2006-342159 (Patent Document 2) has also developed a permanent wave processing agent containing a cyclic mercapto compound such as lactone thiol as a new permanent liquid.

However, the conventional methods including these methods need to be subjected to an oxidation step such as a treatment using an oxidizing agent or natural oxidation after passing through the reduction treatment step, and the operation is complicated and the work takes a long time. Furthermore, after the disulfide bond of hair keratin is cleaved with a reducing agent and before it is recombined with an oxidizing agent, the hair swells due to permanent liquid, etc., or the degree of curling, the gloss of hair after curling, curling The sustainability of was insufficient.

The reducing composition and the oxidizing composition may be applied to the hair for about 5 to 40 minutes at room temperature.

  The present invention provides a permanent kit comprising a reducing composition containing a reducing agent and an oxidizing composition containing an oxidizing agent, wherein the reducing agent and the oxidizing agent coexist and are applied to hair. A permanent kit is also included.

  According to the present invention, the reduction step and the oxidation step that have been conventionally provided as separate steps can be performed at the same time. Furthermore, an excellent perm such as wave uniformity can be formed despite the fact that the method is simple because the disulfide bond is cleaved and recombined quickly.

The permanent kit or set of the present invention can be composed of a combination of a housing part that houses the reducing composition and a housing part that houses the oxidizing composition. However, the kit or set of the present invention may be fractionated or compartmented in one container to contain the reducing composition and the oxidizing composition.

  If each composition constituting the kit or set of the present invention can be applied to hair in the coexistence of the reducing agent contained in the reducing composition and the oxidizing agent contained in the oxidizing composition, the preparation method thereof is There is no particular limitation. Each composition can be prepared using a conventional mixing method, for example, a mixing method using a mixer or the like.

  In addition, the form of both compositions is not limited to a kit or a set, The form of the composition which mixed the component of the reducing composition and the component of the oxidizing composition collectively may be sufficient. However, if the two compositions are left in a mixed state for a long time (for example, 1 hour or longer), the action of the oxidizing agent and the reducing agent is reduced, so that the reducing composition and the oxidizing composition are usually used from the viewpoint of handleability. It is preferable to prepare the product separately by mixing them with conventional methods.

  The ratio of the oxidizing composition to the reducing composition is not particularly limited as long as the weight ratio of the oxidizing agent to the reducing agent is within the above-mentioned range.

In addition, as in the case of damaged hair, in order to promote the action of the oxidizing agent, the pH is adjusted to a range of about 5 to 6.5 (particularly 5.5 to 6) using acid rinse or the like. Also good.

[Perm method]
The permanent method of the present invention is a method for applying a permanent kit to the hair by applying the perm kit (reducing composition and oxidizing composition) to the hair, wherein the reducing agent and the oxidizing agent are allowed to coexist. And treating the hair. This permanent method is characterized in that the reducing step and the oxidizing step are not separate processing steps, and the reducing agent and the oxidizing agent are simultaneously applied to the hair. In the method of the present invention, as in the conventional method, after applying a permanent solution containing a reducing agent to the hair to reduce keratin and performing shaping such as curling around a rod or straightening hair, There is no need to unshape and apply the oxidizing agent to the hair, and shaping can be performed with the oxidizing agent applied to the hair (along with the reducing agent). Accordingly, since the number of steps is reduced compared to the conventional permanent method, the time required for the permanent can be greatly shortened.

  As a method for allowing a reducing agent and an oxidizing agent to coexist, the reducing composition and the oxidizing composition may be applied to the hair after being mixed in advance, and each composition may be separately applied to the same part of the hair at the same time or You may apply at intervals in time. When both the compositions are used in advance, while the reducing agent and oxidizing agent are not deactivated, for example, within 1 hour after mixing, preferably within 45 minutes, more preferably within 30 minutes (especially 10 minutes). Within)). On the other hand, when each composition is applied separately, simultaneous means that both compositions are mixed immediately before application, and the other composition is applied immediately after application of one composition. Including. Further, when the compositions are spaced apart in time, the time may be a relatively short time, for example, within 10 minutes, preferably within 5 minutes, and more preferably within 1 minute. As an application method to hair, application, spraying, or the like can be used depending on the state of the composition. When the composition is creamy or pasty, it is usually applied to the hair by application.

  The application amount of both compositions is used in such an amount that can sufficiently impregnate permed hair, and is usually 10 to 200 ml, preferably 20 to 150 ml, preferably 20 to 150 ml, per adult (hair length to shoulder). Preferably it is about 30-100 ml. In particular, when both compositions are in a semi-solid form such as cream, contact with the scalp of both compositions is suppressed, and therefore skin irritation is low.

  In the process of treating with a reducing agent and an oxidizing agent, tension is applied to the hair to shape it into a desired shape. Examples of the shaping method include a method of winding hair in a desired shape lot (winding) and a method of straightening the hair by applying tension with a curler or the like. The reducing composition and the oxidizing composition may be applied before and / or after hair shaping. However, if both compositions are semi-solid, they should be applied prior to shaping in terms of operability. Is preferred.

  In the present invention, after shaping, far infrared rays may be irradiated or heated, but it is preferable to perform air oxidation without heating. By not irradiating far-infrared rays or heating, not only can the oxidant be effectively expressed in the state of coexisting with the reducing agent, but also can reduce the burden on the hair due to heating, so that a natural perm with good touch can be realized. Further, unlike a digital perm, an air wave perm, an iron perm, and the like, an excellent perm can be simply and easily used without using an electric appliance.

  The time during which the reducing composition and the oxidizing composition are applied to the hair means the time from application of both compositions to the hair by application or the like until washing, for example, 1 to 60 minutes, preferably It is about 3 to 50 minutes, more preferably about 5 to 40 minutes (especially 8 to 30 minutes). In the present invention, an excellent permanent can be applied even in a short time by controlling the type and concentration of the reducing agent, the pH of the reducing composition, the type and concentration of the oxidizing agent, and the like. For example, even when the application time is about 8 to 15 minutes, in the case of curling without heating, a good curl of about 3 to 5 times the diameter of the rod can be formed.

  The shaping such as winding may be performed immediately after the application of the reducing composition and the oxidizing composition, or may be performed for a while after the application of both compositions. The shaping time needs to be secured, for example, 1 minute or longer (for example, 1 to 60 minutes), preferably 3 to 30 minutes, more preferably 5 to 20 minutes (particularly 8 to 15 minutes). When both compositions are applied and left before shaping, the standing time is, for example, 1 minute or longer (for example, 1 to 30 minutes), preferably 2 to 20 minutes, more preferably about 3 to 15 minutes.

  In the perm method of the present invention, not only the effect of shortening the process and the low-temperature treatment, but also the coexistence of a reducing agent and an oxidizing agent allows the keratin disulfide bond to be formed by the reducing agent in the presence of the permanent solution. In addition to being cleaved, the disulfide bond is quickly recombined by the oxidizing agent, and swelling of the hair due to a perm liquid or the like is suppressed. Therefore, cleavage by hydrolysis of the peptide bond of keratin, generation of mixed disulfide, lanthionine bond and cysteic acid, and protein elution are suppressed. Therefore, the hair after perm has little damage and does not feel dry, and has excellent texture and feel.

  The permanent method of the present invention includes a hair washing step as a pre-step of the treatment step with the reducing composition and the oxidizing composition. In the hair washing step, a conventional shampoo is applied to the hair and washed with water in a conventional manner. In addition, you may pass a treatment process after a hair washing process as needed, when the pain of hair is intense. In the treatment process, a conventional treatment agent, a cuticle adjusting agent, or the like may be applied.

  The permanent method of the present invention usually includes a rinsing step after the treatment step with the reducing composition and the oxidizing composition. In the rinsing process, after the hair shaping to which both compositions are applied is removed, both compositions are washed out of the hair with water. In the rinsing step, a conventional rinse agent may be applied to the hair. In the case of damaged hair, acid rinsing may be used to promote oxidation by an oxidizing agent. Examples of acid rinses include conventional ingredients such as alcohols, fragrances, colorants, preservatives, surfactants, amino acids or salts thereof, protein hydrolysates, pH adjusters (phosphoric acid, citric acid, etc.), and the like. May be included. After applying the acid rinse to the hair, for example, it may be left for about 1 to 20 minutes, preferably 1.5 to 10 minutes, more preferably about 2 to 5 minutes and then washed. In addition, the hair may be washed immediately after application.

  The permanent method of the present invention can be used in a method of permanently permanent hair using a permanent liquid, and can be applied to various permanent shapes such as wave and straight. Further, the perm system is not limited as long as it uses a perm solution, and for example, it can be used not only for a cold perm but also for various systems such as a warming perm.
