The following discussion generally pertains to the fields of cosmetology and personal care. More specifically, the following disclosure relates to compositions for relaxing and/or straightening hair, kits containing such compositions, methods of making such compositions, and methods of using such compositions for the relaxation and/or straightening of hair.
The compositions, methods of making, kits and hair treatment methods provided are representative and exemplary and are not intended to limit the scope of the inventive embodiments herein claimed or otherwise described.
In an exemplary embodiment, a representative composition comprises water, a hydrolysate of an oil and/or wax, an alcohol, and a buffer substance. The hydrolysate of the oil and/or wax is comprised of about 6-95% by weight of organic unsaponifiable materials and about 5-96% by weight of organic saponifiable materials. The composition has a pH ranging from about 10 to about 14 when measured in an aqueous solution of 10% by weight of the composition and 90% by weight water. The composition may further comprise a hydroxide salt.
In another representative embodiment, a composition made by a process is disclosed. The composition may be made by a process comprising the steps of combining, in any order, water, an alcohol, a buffer substance, and an oil and/or wax hydrolysate to form a mixture, and adjusting the pH of the mixture to give a pH range from about 10 to about 14 when measured in an aqueous solution of 10% by weight of the composition and 90% by weight water. The oil and/or wax hydrolysate is comprised of a hydrolysate of an oil and/or wax having about 6-95% by weight of organic unsaponifiable materials and about 5-94% by weight of organic saponifiable materials. The pH of the composition may be adjusted, for example, without limitation, by addition of an organic and/or an inorganic hydroxide salt to the mixture.
In an additional representative embodiment, a kit containing a composition is disclosed. The kit may contain instructions for using the composition or any other application aids, whether now known or hereafter devised by those skilled in the art. Instructions may direct that the composition be used to relax and/or straighten hair. The instructions may be reduced to any tangible medium of expression, and may employ various languages, for example, but not limited to, English, German, Spanish, French, Italian, Portuguese, Japanese, Korean, Russian, and/or Chinese.
In a further representative embodiment, a method for making a composition is disclosed. The method comprises the steps of combining, in any order, water, an alcohol, a buffer substance, and an oil and/or wax hydrolysate to form a mixture, and adjusting the pH of the mixture to give a pH range from about 10 to about 14 when measured in an aqueous solution of 10% by weight of the composition and 90% by weight water. The oil and/or wax hydrolysate may be a hydrolysate of an oil and/or wax comprising about 6-95%o by weight of organic unsaponifiable materials and about 5-94% by weight of organic saponifiable materials.

Exemplary embodiments will hereinafter be described in conjunction with the following drawing figures, wherein:
Definitions
All of the various aspects, embodiments and options disclosed herein can be combined in any and all variations or permutations.
As used herein, “a” means one or more, unless otherwise specified.
Open terms such as “include”, “includes”, “including”, “contain”, “contains”, “containing”, “have”, “has”, “having”, and/or the like, mean “comprising”,
The terms “may” and “can” are both intended to equivalently reference permissive constructions, and neither are intended to suggest a degree of permittivity attributed to one as being greater than the other.
The term “or” is intended to denote conjunctive or disjunctive alternatives. The term “or” is not intended to suggest exclusivity among or between any of the member elements or combination of member elements so referenced in a list or set.
The term “and” is intended to denote conjunctive or sequential disposition in time, place, configuration, aggregation or other arrangement. The term “and” is not intended to suggest any required order to be established or maintained among or between any of the member elements or combination of member elements so referenced in a list or set.
Some inventive embodiments contemplate numerical ranges. Every numerical range provided herein includes the range endpoints as discrete inventive embodiments. When a numerical range is provided, all individual values and sub-ranges therein are understood to be present as if explicitly written out. For example, the range 10-50 is understood to include the sub-range 20-40 as if it were explicitly written out.
When used to modify a discrete number, the term “about” means ±10% of the number it modifies. For example, “about 90” provides for a range of values from 81 to 99, including the number 90. When the term “about” is used to modify a range, “about” means ±10% of the larger number in the range as applied against both the lower endpoint and the upper endpoint. For example, “about 49-80” provides for a range of from 41 (i.e., 49 minus 8) to 88 (i.e., 80 plus 8). For the purposes herein, in no event will the amount of the modification as calculated from the upper endpoint of a range be applied against the lower endpoint value of the range to effectively reduce the lower endpoint to a value less than zero. For example, “about 5-70” provides for a range of from 0 to 77.
When the claims and/or specification reference a composition having a percentage (%) weight fraction of a specific component (e.g., organic saponifiable materials, organic unsaponifiable materials, etc.), the “weight fraction” is intended to reference the explicitly described component so constituted before any other materials are added or taken away. Accordingly, it is the intent of the inventors to prevent the avoidance of literal or equivalent infringement hereunder by operation of physical dilution or effective concentration (subsequent or ab initio) in attempts to design around the values and/or ranges recited herein. For example, “a hydrolysate of an oil and/or wax, said hydrolysate comprising about 6-90% by weight of organic unsaponifiable materials and about 5-95% by weight of organic saponifiable materials” shall be understood to have the recited weight percentage values reference the explicitly described “hydrolysate” component and not the effective percentages otherwise resulting from pre-/post-addition of alcohol, buffer substance, water, solvents, emulsifiers, fragrances, pigments, dyes, and/or the like, etc.
A buffer substance contains and/or is an acid, a base, and/or a salt. In one representative embodiment, the buffer substance may be a mixture of an acid and its conjugate base. The buffer substance may, but is not required to, buffer any composition to which it is added, and may be, but need not be, part of a buffer system.
To relax hair means to decrease the amount of curl in the hair (e.g., to partially or fully remove curl from the hair). When decreases in the amount of hair curl are described, they are relative to control hair that has not been treated with a hair relaxing process and/or a hair relaxing composition. Assessments of hair straightening generally correspond to a subjective metric employed to indicate 100% as substantially complete straightening of the hair relative to an un-treated control (itself referenced as 0%). Accordingly, a score of 50% relaxation would correspond to a subjective assessment where the hair so scored would be observed to have only half (50%) of the curl as compared with an un-treated control.
Partial relaxation of the hair may be understood to alternatively, conjunctively and/or sequentially comprise smoothening or softening of larger waves/curls and/or defrizzing of smaller waves/curls.
The concept of a “hydrolysate of an oil and/or wax” shall be understood to mean a “hydrolysate of an oil and/or hydrolysate of a wax”. The concept of an “oil and/or wax hydrolysate” shall be understood to mean an “oil hydrolysate and/or wax hydrolysate”, The phrases “hydrolysate of an oil and/or hydrolysate of a wax” and “oil hydrolysate and/or wax hydrolysate” shall be understood to have the same meaning.
Representative hydrolysates may be produced in situ and/or via chemical hydrolysis. Hydrolysates in accordance with various representative embodiments of the invention may also be at least partial produced via a combination of two or more chemical components that otherwise would correspond to the products produced from one or more hydrolysis reactions. Hydrolysates in accordance with various other representative embodiments of the present invention may correspond to at least one substantially synthetic component that is suitably adapted to mimic or otherwise at least partially function similar to one or more chemical components corresponding to the products produced from one or more hydrolysis reactions.
Where any reference herein is made indicating use of the disclosed invention to straighten/relax/smoothen/soften human hair, it is understood that the hair of any mammalian animal my also be so treated to accomplish any substantially similar goal of straightening/relaxing/smoothening/softening the hair of a mammalian subject.
Terms in this application control in the event of a conflict with a patent, patent application, or publication term that is incorporated by reference.
People routinely relax and/or straighten their hair for cosmetic and aesthetic reasons. Conventional hair relaxing methods and compositions employ extreme temperatures and/or chemicals that can damage hair, are hazardous, and/or produce or are themselves responsible for malodor. Furthermore, conventional hair straightening methods and compositions can relax hair for a relatively brief duration of time and so require regular, repeated applications. There is a need for hair relaxing compositions, kits and methods: which do not need to employ, for example, extreme physical measures such as heating hair at high temperature; that do not need to employ hazardous substances such as, for example, formaldehyde; that do not need to employ offensive, malodorous substances such as, for example, thiols; and that relax hair for a desired duration of time. Finally, there is a need for relaxed and/or straightened hair that is suitably adapted for use, for example, in a wig, a hair piece, a hair extension, a hair tress, or a toupee.
Disclosed herein are compositions, methods and kits for relaxing and/or straightening hair, and hair that has been relaxed and/or straightened by the disclosed methods and/or compositions, that can address the above-described needs and problems.
In a representative embodiment, a composition is disclosed. The composition comprises water, a hydrolysate of an oil and/or wax, an alcohol, and a buffer substance. The hydrolysate of the oil and/or wax comprises about 6-95% by weight of organic unsaponifiable materials and about 5-96% by weight of organic saponifiable materials. The composition has a pH ranging from about 10 to about 14 when measured in an aqueous solution of 10% by weight of the composition and 90% by weight water. The composition may further comprise a hydroxide salt.

The instructions may be in any language or in at least two languages. For example, without limitation, the instructions can be in English, Spanish, German, French, Japanese, Russian, Chinese, Portuguese, Vietnamese, or any combination thereof.
The following examples are illustrative and do not limit the scope of the disclosure of the specification or claims.
Representative hair relaxation formulations may be prepared in accordance with Table 2 and Table 3 vide infra. The “FC3” components recited therein correspond to hair relaxer/straighter compositions in accordance with a representative embodiment of the present invention. The FC3 composition is generally intended to be included as one of several components in a finished relaxer formula, as shown, for example, in Table 2 and Table 3.
In an exemplary representative embodiment of the present invention, the “FC3” component of the hair relaxer formulations shown in Table 2 and Table 3 may be manufactured in accordance with the following:
An 50% by weight potassium hydroxide solution was made by weighing approximately equal amounts of KOH and water in separate vessels. Water was added to the KOH. After cooling, the total weigh was adjusted by adding water to compensate for evaporative loss in the exothermic mixing process. A 47% weight equivalent amount of the 50% potassium hydroxide solution was combined with the remaining components to make the representative relaxer composition shown in Table 1. For example, about 47 g of the 50% potassium hydroxide solution was combined with the remaining components, the remaining components totaling about 53 g.
A potassium phosphate solution was then made with 6.4% wt. equivalents of water as measured by weight of the final relaxer composition. In a representative embodiment in accordance with the relaxer composition disclosed in Table 1, about 13.6 g of potassium phosphate was added to about 6.4 g of water for inclusion in a 100 g batch of relaxer composition.
Next, 33% wt. equivalents Floraesters K-100 as measured by weight of the final relaxer composition was mixed with the potassium phosphate solution at room temperature.
The KOH solution was slowly added to the mixture at room temperature with substantially continuous mixing until the batch was uniform and homogeneous.
Accordingly, a 100 g batch of relaxer composition, in accordance with the representative embodiment disclosed in Table 1, may comprise about 33 g Floraesters K-100, about 13.6 g potassium phosphate, about 6.4 g de-ionized water, and about 47 g 50% aqueous KOH solution.
Thereafter, the resulting composition (i.e., the “FC3” material) manufactured in accordance with a representative embodiment of the present invention may be incorporated into a substantially finished hair relaxer formula corresponding with, for example, either of the following:
The pH of the 16.7% strength relaxer formulation in Table 2 was measured as 12.8 in an aqueous solution comprising 10% relaxer formulation and 90% water. The pH of the 25% strength relaxer formulation in Table 3 was measured as 13.1 in an aqueous solution comprising 10% relaxer formulation and 90% water.
To apply either of the exemplary relaxer formulations described in Table 2 or Table 3, the hair of a human subject is sectioned into four quadrants and clipped to keep each quadrant substantially separate. Quadrant-by-quadrant, the exemplary relaxer formulation is applied to the hair using a brush similar to the brash used by a cosmetologist to apply hair dye or other coloring agents to the hair. Within each quadrant, the relaxer formula is applied approximately one inch from the scalp in substantially horizontal segments. The relaxer formula is then brushed down the length of the hair to ensure saturation. Hair foils may be optionally employed to prevent or otherwise impede migration of the relaxer formula toward the subject's scalp.
The formulation is permitted to dwell on the hair, for example, for 15-30 minutes followed by rinse out with water. The hair is then shampooed using, for example, a neutralizing shampoo, and washed substantially free of relaxer formulation.
In the case where experimental trials may be needed to determine relative effectiveness of a given combination of relaxer compositions in accordance with various representative embodiments of the present invention, finished relaxer formulations, dwell times, hair types, and/or the like, etc., it may be beneficial to perform comparisons of results obtained from relaxer treatment of hair tresses rather than results obtained from treatments performed on the heads of human subjects. For example, the following protocol was used to determine relative relaxation performance of an exemplary embodiment of a relaxer composition (FC3) in a relaxer formulation (see, for example, Table 2 and Table 3) as a function of dwell time and percent (%) strength of the relaxer composition in the finished relaxer formulation.
Several one inch (1″), tight, curly, Caucasian hair tresses were washed with shampoo to remove any residue from the hair. 5-10 milliliters of finished relaxer formulation was applied to the hair tresses, combed through the hair, and manually manipulated for approximately 1-2 minutes using fingers and a comb. The hair tresses were then wrapped in foil with physical orientation of the hair fibers as straight as possible. The tresses were left for 15-60 minutes. Manipulation was repeated for approximately 1-2 minutes at the middle and end of the process. The hair tresses were then rinsed with water and dried. The hair tresses were then shampooed using a neutralizing shampoo and washed substantially free of relaxer formula.
The following visual results were observed, in order from left to right, as depicted in
