Description

Title of the invention: METHODS FOR TREATMENT OF KERATIN FIBERS IN A DYEING PROCESS technical field

[0001] This disclosure relates to processes for treating keratin fibers, such as hair, for example, repairing damaged keratin fibers, adding strength to keratin fibers, and / or reducing the elasticity of keratin fibers, in connection with a keratin fiber dyeing process. BACKGROUND

[0002] Consumers use cosmetic compositions and processes to change or improve the appearance of their hair, for example, by changing the color, style, and / or shape of the hair, and / or by imparting various properties to the hair, such as shine and revitalization. However, many compositions and processes for altering the appearance of hair, such as permanent hair color modification compositions and processes, involve harsh chemical treatments. For example, hair color modification compositions and processes generally require the presence of harsh chemical compounds, such as oxidizing agents. In order to change the hair color, these components must first break down the natural components of the hair fibers.

[0003] It is known that, although such processes effectively alter hair color, the chemical agents used inherently cause hair damage and negatively impact the strength, elasticity, and porosity of the hair fibers. For example, hair that has been bleached, dyed, styled repeatedly, etc., is often dry, frizzy, and generally unpleasant to the touch and appearance. Furthermore, damaged hair is brittle and / or exhibits increased elasticity, leading to more frequent breakage. As such, consumers seek compositions and processes to prevent or minimize such damage and / or to repair hair that has been damaged by these treatments and processes.In particular, consumers want strong hair that does not break easily, that can be stretched or manipulated while retaining the ability to return to its original state without breaking (i.e., with reduced elasticity), that is soft and healthy to the touch and also looks shiny and healthy.

[0004] However, it has proven difficult to formulate compositions that satisfactorily meet these requirements. For example, some compositions that Attempts to provide a solution merely coat the hair with compounds that may improve its feel and appearance; however, this approach is only temporary and superficial. Rather than preventing or repairing hair damage, this approach simply masks the damage until the next rinse or wash. Other formulations attempt to treat damage within the hair fiber, but to date, they have not been satisfactory.

[0005] The present inventors have now discovered a synergistic combination of components that is remarkably effective in preventing or minimizing hair damage and treating damaged hair. Hair treated with compositions according to the disclosure shows remarkably reduced signs of damage, including increased strength and / or reduced elasticity, particularly hair that has been damaged by harsh chemical treatments, such as dyeing.

[0132] The disclosure relates to methods for treating keratin fibers with a treatment composition as disclosed in connection with a hair dyeing process. The methods include applying a treatment composition to the hair, optionally leaving the composition on the hair for a period of time (“treatment time,” “resting time,” or “processing time”), and optionally rinsing the composition from the hair. The treatment composition may be applied to the hair before and / or after the application of a hair dye composition to the hair, or may be applied to the hair simultaneously with a hair dye composition.

[0133] Although not necessary, the processes according to the disclosure may also include a step of heating the hair to which the treatment composition has been applied, for example, during the resting period while the treatment composition is on the hair. For example, a hair dryer, a hair dryer hood, etc., may be used.

[0134] The period of time during which the treatment composition is left on the hair may be of an appropriate duration to allow the active agents to provide benefits to the keratin fibers, such as approximately 30 seconds, approximately 1 minute, approximately 2 minutes, approximately 5 minutes, approximately 10 minutes, approximately 15 minutes, approximately 20 minutes, approximately 30 minutes, approximately 45 minutes, approximately 1 hour, approximately 2 hours, etc., or may vary from a period of time using any of the preceding values ​​as upper and lower limits.By way of non-limiting example, the exposure time can range from approximately 30 seconds to approximately 60 minutes, from approximately 30 seconds to approximately 45 minutes, from approximately 30 seconds to approximately 30 minutes, from approximately 30 seconds to approximately 20 minutes, from approximately 30 seconds to approximately 15 minutes, from approximately 30 seconds to approximately 10 minutes, from approximately 30 seconds to approximately 5 minutes, from approximately 1 minute to approximately 60 minutes, from approximately 1 minute to approximately 45 minutes, from approximately 1 minute to approximately 30 minutes, from approximately 1 minute to approximately 20 minutes, from approximately 1 minute to approximately 15 minutes, from approximately 1 minute to approximately 10 minutes, from approximately 1 minute to approximately 5 minutes, from approximately 2 minutes to approximately 60 minutes, from approximately 2 minutes to approximately 45 minutes, from approximately 2 minutes to approximately 30 minutes, from approximately 2 minutes to about 20 minutes, from about 2 minutes to about 15 minutes, from about 2 minutes to about 10 minutes, from about 2 minutes to about 5 minutes, etc.

[0135] The period of time during which the dye composition is left on the hair may last for a suitable duration to allow the desired color to be obtained, which can range from about 1 minute to about 60 minutes, such as from about 3 minutes to about 45 minutes, from about 5 minutes to about 30 minutes, or from about 10 minutes to about 20 minutes.

[0136] In exemplary embodiments, a treatment composition as disclosed may be applied to the hair before, during, and / or after the application of a dye composition, with or without intermediate rinsing. For example, such a process may include applying a treatment composition as disclosed to wet, damp, or dry hair, leaving the composition on the hair for an appropriate processing time, optionally rinsing the hair, and then substantially immediately afterwards (i.e., as part of the same hair dyeing process), with or without intermediate rinsing of the hair, applying a hair dye composition to the hair.Another example of the process may include applying a dye composition to the hair and, substantially immediately thereafter (i.e., as part of the same hair dyeing process), with or without intermediate rinsing of the hair, applying a treatment composition as disclosed to the hair. In either of the preceding embodiments, the treatment composition and the dye composition may optionally be layered one on top of the other on the hair (without rinsing), or may optionally be applied to the hair in alternating layers (rinsing) during the hair dyeing process.As a further example of a process, a treatment composition as disclosed may be added to or mixed with a hair dye composition, for example, an oxidative dye base composition, an oxidizing composition, or a mixture of both, at or near the time of use. In yet another example, a treatment composition and a dye composition may be applied simultaneously to the hair, for example, using a dual-chamber applicator configured to dispense two compositions at the same time. Thus, it is envisaged that treatment compositions as disclosed may be incorporated into a hair dyeing process to reduce, minimize, or prevent hair damage that might otherwise result from such harsh chemical treatments.

[0137] By way of non-limiting example of hair dyeing processes according to the disclosure, a treatment composition such as described herein may be applied to wet, damp, or dry hair and then left to act for a processing time such as described herein, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heating. The hair may then be rinsed, and a hair dye composition may then be applied. is applied according to standard hair dyeing routines. As a further, non-limiting example of hair dyeing procedures as disclosed, a treatment composition such as described herein may be applied to wet, damp, or dry hair and then left to act for a processing time as described herein, for example, from approximately one minute to approximately two hours, such as approximately five minutes to approximately one hour, optionally with heat. Without rinsing the treatment composition from the hair, a dye composition may be applied to the hair, and then the hair dyeing process is carried out according to standard hair dyeing routines.

[0138] As another non-limiting example of hair dyeing processes according to the disclosure, a hair dye composition may be applied to the hair to dye the hair according to conventional dyeing routines. The hair may then be rinsed. Alternatively, a treatment composition such as described herein is applied to damp, wet, or dry hair and left to act for a processing time as described herein, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heat. The hair may then be rinsed. As another non-limiting example of hair dyeing processes according to the disclosure, a hair dye composition may be applied to the hair according to conventional hair dyeing routines.Without rinsing the hair dye composition, a treatment composition such as the one described here can be applied to wet, damp, or dry hair and left to act for a processing time as described here, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heat. The hair can then be rinsed.

[0139] Surprisingly, hair treated with the compositions and processing methods disclosed before, during, and / or after the dyeing process exhibits less damage than dyed hair not treated with the compositions and processing methods disclosed before, during, and / or after the dyeing process. The hair may have lower elasticity and / or higher tensile strength than similarly dyed but untreated hair as disclosed. Thus, additional processes disclosed include processes for reducing or minimizing hair damage in a hair dyeing process, processes for preventing hair damage compared to a hair dyeing process, and processes for improving the elasticity and / or tensile strength of hair in a hair dyeing process.

Similarly, the expression "one of their / her salts" also refers to "their / her salts."Thus, when the disclosure refers to "an element chosen from the group consisting of A, B, C, D, E, F, one of their salts or mixtures thereof", it indicates that one or more elements from A, B, C, D and F may be included, that one or more salts from a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or that a mixture of any two elements from A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.

[0143] The expression "and / or" should be understood as including both the conjunctive and the disjunctive. For example, "amino acids and / or their salts" means "amino acids and their salts" as well as "amino acids or their salts", and expressly covers either one or the other.

[0144] In this document, the term "salts" throughout the disclosure may include salts containing a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is not exhaustive. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

[0145] Unless expressly stated otherwise, "approximately" means + / - 5%.

[0146] As used here, if a component is described as being present "in an amount less than or equal to" a certain amount, it is expected that this component will be present in the composition, namely, present in an amount greater than 0%.

[0147] All quantities indicated here are relative to the quantity of active material, unless otherwise stated.

[0148] All percentages, parts and ratios herein are based on the total weight of the compositions in this disclosure, unless otherwise stated.

[0149] In this application, the terms "keratin fibres" and "hair" are used interchangeably without being intended to be restrictive. Those skilled in the art will understand that keratin fibres include hair, such as the hair growing on the scalp, which is frequently dyed in a cosmetic process to alter the appearance of hair.

[0150] As used herein, the expression "apply a composition to the hair," and its variations, is intended to refer to bringing the hair into contact with at least one of the compositions described herein, in any manner whatsoever. It may also refer to bringing the hair into contact with an effective quantity.

[0151] The expression "hair treatment" (and its grammatical variations) as used herein refers to the application of the compositions described herein to the surface of the hair. The expression "hair treatment" (and its grammatical variations) as used herein also refers to bringing the hair into contact with the compositions described herein.

[0152] Unless otherwise defined for any specific embodiment, the expression "substantially free" or "essentially free" as used herein means that there is less than about 5% by weight of a specific material added to a composition, relative to the total weight of the composition. For example, compositions may include less than about 4%, less than about 3%, less than about 2%, less than about 1.5%, less than about 1%, less than about 0.5%, less than about 0.1%, less than about 0.01%, less than about 0.001%, or less than about 0.0001% of the specified material. A composition that is "free" of a component is deemed to contain no amount of the specified component. However, it is understood that the expressions "free" and "substantially free" refer to the amount of a component added to the composition, without including any quantity of the component present in the composition as a minor component in a raw material.

[0153] The following examples are intended to illustrate embodiments of this disclosure but are not intended to be limiting. It will be obvious to those skilled in the art that various modifications and variations can be made to the compositions and processes of the invention without departing from the spirit or scope of the invention.
