Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to cold permanent or temporary waving or straightening of hair, and more specifically to controlling the tightness and hold of the waves and hardly damaging the hair. M1 composition and method for waving and straightening hair. "Cold permanent" waving or straightening is distinguished from hot permanent waving or straightening, in which the hair is heated to a high temperature of about 90℃, and hair is heated to about 50℃ with or without external heat applied to the hair.
It is used to create long-lasting waves and curls in the hair, or to straighten the hair at a temperature below. "Temporary" waving is the creation of waves that gradually loosen and disappear almost completely within 1.2 J at most under normal conditions, and is desired by those who want to change their style frequently. "Cold straighten" refers to removing curls and strands from hair at temperatures below about 50 degrees Celsius without the need for heated combs or other heated tools. "Itami"
refers to the weakening of the hair as evidenced by increased hair loss under stress and increased brittleness when subsequently dyed, bleached, or waved. This "damage" is proportional to the number of unmodified disulfide keratin bonds in Annaka after waving.

[Prior Art] It is possible to create waves in the hair by curling it while softening it by sulfite decomposition.
No. 3,644,084, reported significant sagging of the hair as measured by a reduction in modulus ranging from 21% to 49%. Additionally, neither this patented method nor any other method of cold permanent waving hair provides any means of adjusting or controlling the degree of waving without prior experience with the particular hair being waved. The receptivity of human hair to permanent waving differs from person to person, so
When waving a person's hair for the first time with a particular waving composition or method, the usual waving should be done in small amounts depending on the conditions, treatment time, waving lotion and concentration of neutralizing agent to see the results. of hair was subjected to this treatment,
It is common practice to adjust the conditions for waving hair so that the expected results are as close as possible to the preferences of the individual undergoing waving. Once the wave is completed.

The tightness of the waves cannot be changed except by repeating the entire process.

[Summary of the Invention and Mode of Implementation] A water-soluble mercaptan such as cysteine is mixed with sulfite (or hydrogen sulfite or hydrosulfite) and the molar ratio of sulfite:mercaptan is set in the range of 5 = 1 to 1, 5
, the concentration range of sulfite is 0.1-1.5 mol, the concentration of mercaptan is 0.1-1.5 mol, and the pH is 5.5-8.
5. Use an aqueous lotion preferably containing 6.5 to 7.5 to curl or straighten hair (remove fine frizz from the hair), then add crosslinking agents, oxidizing agents and reducing agents. It has been found that hair damage can be significantly reduced by reshaping the hair by applying an aqueous reshaping lotion with a pH of 7 to 12. The resulting hair can be made more wavy or straightened at any time by applying an aqueous neutralizing lotion containing an oxidizing agent to set the hair in the desired shape and make it permanent. When curling or waving your hair,
If desired, simply expose the curled and reshaped hair to the air at ambient temperature and stress-free for a period of time to allow the hair to loosen into a slightly curled configuration between the reshaping and neutralization steps. Just by adding this step, you can loosen the tightness of your curls and waves. actual.

It can be seen that this loosening step takes at least 8 hours and preferably 16 hours or more to achieve significant loosening.

This allows each person receiving the wave or the worker applying the wave to check the wave at regular intervals during the loosening time and make it permanent. A similar result is obtained when hair is straightened to 11' length according to the present invention, in which the tightness of the waves can be controlled by substantially stopping or at least slowing down the wave length.

Since the degree of damage to your hair is extremely low, you will be able to dye your hair on the same day as waving it.

By doing the above, you can improve the process of first wetting your hair with water instead of waving lotion before wrapping it in a curler. 1. Apply waving lotion to the entire curled tress at the same time, especially for strong waves. ensure uniform results are obtained. The degree of damage is determined by methylene blue absorption as described in British Patent G132.027,195rl or by measuring the relative modulus of untreated and treated hair as described in Ilsiung, US Pat. No. 3,644,048. It can be easily measured by

Therefore, the present invention provides a method for shaping the hair by keeping the hair in a curly or straight shape and applying a first aqueous lotion having a pH of 5.5 to 8.5 containing a water-soluble mercaptan together with a water-soluble sulfite, bisulfite or hydrosulfite. P1 with no cross-linking agent, other agents, or reducing agent
Reshape the hair by touching it with the aqueous lotion of 17 to 12, and if you want to make it permanent, apply an aqueous lotion containing an oxidation neutralizer to the reshaped hair to shape the hair into the desired shape. Includes methods for waving and straightening. If somewhat strong curls or waves are desired, the pH should be 8°5~
12 or most preferably p119-11, tap water with a pll of about 7 is the most convenient remolding lotion for domestic use. This process also involves exposing the curled and reshaped hair to air at ambient temperature for a period of time long enough to loosen the curled and reshaped hair into a less tightly curled state after reshaping and before neutralization to avoid stressing the hair. It also includes a method of waving hair by the aforementioned process including the additional step of waving the hair.

A waving or straightening lotion containing a sulfite, a Ti hydrogen sulfate or a hydrosulfite and a water-soluble mercaptan is capable of softening and plasticizing the hair fibers into a desired shape. To do this, curl the waving hair in the usual way (the curler rod should have a diameter of 0.15 to 4C).
and maintain a curled shape during contact with the waving lotion and during the reshaping step; if necessary, cover the hair with a tarpan during the waving and/or reshaping step. The reshaping step may be followed by rinsing with water, for example, rinsing is not important, especially when water alone is used as an aqueous reshaping lotion, if the hair is subjected to an optional loosening step after the reshaping. .

First, unwind the hair from the curler to avoid stress during this step. Then apply the oxidizing (i.e., neutralizing) agent0;j, although this rewinding is not absolutely necessary.
If you want to skip the optional loosening step of re-wrapping the curler for convenience, simply leave the hair in the curler until after applying the oxidizing (i.e., neutralizing) agent; To make the stretching permanent, an oxidizing or neutralizing agent is applied, followed by a final rinse with water.

When carrying out the invention to straighten hair, a straightening lotion containing a water-soluble mercaptan and a sulfite, sulfite aqueous salt or hydrosulfite may be used in combination with a gum, such as guar gum or a derivative thereof, or other 5 natural water-soluble gums or hydrocolloids; 5 carrageenan, agar or other water-soluble polysaccharides; polyvinyl alcohol or vinyl polymers with carboxyl groups; 1 lotions such as Carbobol; fumed silica; The lotion is thickened with a thickening agent to prevent the lotion from dripping off the hair, and then the thickened lotion is combed through the hair repeatedly, applying tension (stress) to straighten the hair until the desired straightness is achieved. ), water-based lotions applied during the reshaping step after straightening are also thickened and applied by shisuki, but this is not important as long as the holder remains in a straightened shape during the reshaping step. It can be used alone as an aqueous reshaping lotion, but if desired, the straightening and/or reshaping step may be followed by a water rinse.

Wrap the hair around the curler with enough tension to remove frizz, then apply waving or straightening lotion and reshaping lotion while continuing to apply tension to the hair to create waving or straightening. In some cases, it may be possible to combine a rope paddle and a frizz remover.

The waving or straightening lotions may contain water-soluble sulfites, bisulfites or hydrosulfites, such as alkali metal or ammonium salts of suitable acids or salts of alkanolamines. The relative proportions of sulfite, bisulfite and hydrosulfite are according to 911 of the solution. pll is 5.5-8.5
Among the alkanolamine salts, trialkanolamine salts are preferred, but monoalkanolamine salts have an odor and tend to act as crosslinking agents, so the latter is preferred. This is because I would like to avoid using . To adjust the PLL, an alkaline substance such as an alkali metal, ammonium hydroxide or trialkanolamine, or an alkaline mild WB solution may be used, and instead of the hydroxide, a corresponding carbonate or bicarbonate may be used.
The concentration of sulfite, bisulfite or hydrosulfite in waving lotions is 001-1.5.
It is a mole. However, the molar ratio of sulfite to mercaptan should not fall within a predetermined range.

The water-soluble mercaptan present in the waving lotion is preferably cysteine, although various mercaptans can also be used. Aliphatic mercaptans such as thioglycolic acid, dimercaptoadipic acid, thiolactic acid, their salts and alkyl-esters, thioglycols, thioglycerin, etc. are preferred, the mercaptans being present in amounts of 0.1 to 1.5 molar. In order to damage the hair as little as possible, not only must the concentration be within the above limits, but also the molar ratio of total sulfite to mercaptan, i.e. sulfite, bisulfite and/or hydrosulfite, is 5: 1 to 1 near, must be 5 2
．． 5:I to 1:2.5 is preferred.

Waving or straightening lotions (sulfite solutions) are made from mercaptans that are stable in solution, such as thioglycolic acid, dimercaptoadipic acid, thiolactic acid, and their salts and alkyl-esters, thioglycols, and thioglycerin. In some cases it can be provided to the consumer in the form of a single ready-to-use solution (although the preferred mercaptan, cysteine, is unstable in such solutions, so the complete solution must be used immediately before using it). Therefore, the preferred embodiment of the invention is to add a water-soluble sulfite, bisulfite or hydrosulfite salt, such as an alkali metal, ammonium or alkanolamine salt of a suitable acid, to a concentration of 0.1. ~1.5 mol, p1
It is supplied to the consumer in the form of a kit containing one container containing a predetermined amount of aqueous lotion from 15.5 to 8.5 (preferably about 6.5 to 7.5). A buffer solution for pH adjustment can be used as necessary.

The kit also includes a second container of cysteine in dry solid form containing instructions for dissolving the cysteine in an aqueous sulfite solution before use.

The amounts of the components in the kit are such that the molar ratios and concentrations fall within the desired ranges described above. In the case of embodiments of the invention containing mercaptans other than cysteine, the waving or straightening lotion, either in pure form or in aqueous solution, may be placed in one container and the mercaptan in another container, if desired. It is also possible to supply kits to consumers.

Lotions for waving or straightening may contain humectants (nonionic humectants such as polyoxyethylene-lauryl-ether, polyoxyethylene monostearate, polyoxyethylene-alkyl-phenol, sorbitan monolaurate, etc.) are preferred. ) is also desirable, but not essential.

Anionic wetting agents such as triethanolamine oleate, sodium lauryl sulfate, and sodium stearate may also be used. Swelling agents such as alcohols, urea, dimethylurea or lactams may also be present, as well as conventional hair conditioning agents such as quaternary ammonium salts containing long chain IIFI aliphatic groups for waving or straightening. Typical hair conditioning agents that may be present in the straightening lotion include N-alkyl-trimethyl-ammonium chloride in which the alkyl group has 10 to 20 carbon atoms, soybean oil alkyltrimethyl-ammonium chloride, Examples include di-soybean oil alkyldimethylammonium chloride, chassis oil alkyldimethylammonium chloride, polymethacrylamidopropyl-trimethyl-ammonium chloride, quaternium-15, cetyl-dimethyl-hydroxyethyl-ammonium chloride, quaternium-40, and the like. The amounts generally considered effective for the initial purpose of humectants, hair conditioners and swelling agents, if present, are 0.01 to 1% by weight for the first two.
On the order of 1 engraving agent is a larger amount on the order of 3-20 rf1m%.

Conventional additives such as softening mulberry, colorants, fragrances, preservatives, etc. may also be present.

These optional agents may be supplied in one or more separate containers in the kit or combined with the waving lotion in ready-to-use form; in the case of the preferred mercaptan, cysteine, the optional agent is ! T! It may be combined with an aqueous solution of sulfate, bisulfite or hydrosulfite.

The hair is exposed to a waving or straightening lotion preferably at ambient temperature for a sufficient period of time to soften the hair to a plastic state, usually 5 to 60 minutes, so that the hair has no tendency to return to its original shape or Allowing it to assume its tightly coiled or straightened (uncurled) shape without heat. A plastic tarpan or other hair covering may be used during this step to speed up the process or may be gently dampened if desired.

The only aqueous lotion employed in the reshaping step, which repairs many of the disulfide joints in the hair keratin, is water with a pH of about 7; however, for moderately high curls, aqueous reshaping lotions may be used. It is better to have a higher pH, preferably by adding an alkaline agent such as ammonium hydroxide, alkali metal carbonate, compositional acid salt, trialkanolamine, etc. to raise the pH to a level of 8.5 to 12.0 or the most suitable level. The aqueous reshaping lotion, preferably adjusted to a level of 9.0 to 11, optionally contains conventional humectants and/or hair conditioners, emollients, colorants, fragrances, preservatives, etc. If optional hair conditioners or humectants are present in the waving lotion, the effective concentration of these agents in the water rinse is lower than in the waving lotion, from 0.005 to 0. It can be on the order of 1% by weight. Also, to achieve the benefits of the present invention, the aqueous reshaping lotion should not contain crosslinking, oxidizing, or reducing agents, and the lotion should be applied to the hair while the hair is still in a curled or straightened configuration. It is also important to do so. Crosslinking agents that must be excluded from aqueous remolding lotions include aldehydes, ketones, monoethanol-amines and carbon atoms of 1 to 6 carbon atoms.
low molecular weight amines such as alkyl-amines, reagents such as polyvalent gold salts and similar reagents that react with the thio or mercapto groups of the treated hair.

Oxidizing agents that must be excluded include hydrogen peroxide, sodium bromate, sodium perborate, and other common oxidative neutralizing agents; reducing agents that must be excluded include those in waving or straightening lotions. various mercaptans, such as any of those present in hair, sodium borohydride, and other reducing agents capable of reducing the disulfide groups of the hair.

Sulfide of hair When waving or straightening hair, the disulfide bond is broken by the reaction between the disulfide bond in hair keratin and sulfite as shown in the reaction formula below, and S sulfo group and mercapto (or thio) group are formed on hair keratin. The group arises: -5-3-K + 11503-;
-5-803-+ KSII.

In the process of the present invention, where both sulfite and mercaptan are present within the specified proportions, the sulfide essentially acts as a catalyst and the reaction is essentially mediated by keratin-5-
It is believed that no sulfo group is produced, but instead a mixed disulfide and keratin-mercaptan is produced according to the following formula: +1SO3- to -5-5-K + R3II, = to -5-5-R+
K.S.II.

In the second step of the invention, the reshaping step, dilution with excess aqueous reshaping lotion reduces the concentration of water-soluble mercaptans, and this, along with a deliberate increase in pH, balances the final reaction. It is believed that some of the disulfide bonds in keratin are repaired in the new shape of the hair as it is shifted to the left. When a conventional neutralizing solution containing an oxidizing agent is then applied to the hair, the soluble mercaptans are completely destroyed by oxidation and removed together with the residual sulphites, ensuring the permanence of the new shape of the hair.

If the product of the invention is supplied to the consumer in the form of a kit, the aqueous reshaping lotion is added to each individual container in an appropriate amount of at most 0.
(If it is only water, it is usually not included in the kit.

Typically, the reshaping step involves leaving the curled hair in contact with an aqueous reshaping lotion at ambient temperature.
It takes ~50 minutes. If desired, use a tarpan or gently heat the hair to 50°C.

When ammonium sulfites, bisulfites, or hydrosulfites are used in lotions for waving or straightening, the ammonium salts are first removed by rinsing with tap water at a pH of 5 to 7, and then the ammonium salts are rinsed with tap water at a pH of 7 to 12.
Reshaping in two steps by applying an alkaline reshape lotion is desirable but not necessary; rinsing with tap water may result in free ammonia and associated odors when applying an alkaline reshape lotion. The water itself acts as a remolding lotion as mentioned above.

To observe wave tightness and hair straightness following the aqueous reshaping step, the hair, or a representative sample tress, is removed from the curl and allowed to dry. If the tightness and straightness are acceptable, the hair all over the face is then treated with a normal neutralizing solution, i.e. an oxidizing agent such as peroxide-bromate, perborate, percarbonate, etc. The aqueous solution is saturated to permanently set the hair in its current curled or straightened shape with substantially no further change in shape. Therefore, the effect of the neutralizing solution is to eliminate residual mercaptans and sulfites in the amino acid.

However, in many cases when the hair is waved.

Sometimes the first curls that form on the hair after the reshaping step are tighter than desired, in which case it is necessary to delay the treatment with the neutralizer, i.e. after the hair has been removed from the curler.
Apply stress under ambient conditions to 11 tin, which can be wet or dry, and leave it in an air conditioner to reshape the keratin disulfide (until the hair is wrapped tightly and loosely). Slowly loosen the tension to the desired degree.
It may take up to 3 weeks for 1 temple + + a force, and it is usually 8~
481 temple f + ll force 1, but at that time, by applying a neutralizing liquid in the usual way, the curls and waves will be removed (-manent number) and will not loosen any more. The curls and waves will completely disappear within 2-3 weeks.
This rate of loosening can be increased somewhat by increasing the temperature.
