Definitions

  • the present disclosure relates to compositions for altering the color of hair and methods of using the compositions for altering the color of the hair, while at the same time enhancing or maintaining fiber integrity of the hair and/or preventing damage to the hair.
  • compositions to change or enhance the appearance of their hair, e.g., by changing the color, style, and/or shape of the hair, and/or by imparting various properties to hair, such as shine and conditioning.
  • Many of the known compositions and processes for changing or enhancing the appearance of the hair involve harsh chemical treatment of the hair.
  • the process of altering the color of hair may involve lifting the color of the hair and/or depositing an artificial color onto the hair, which provides a different shade or color to the hair.
  • the process of lifting the color of hair also known as lightening, generally requires the use of compositions that comprise at least one oxidizing agent.
  • oxidizing agents enter the hair shaft and react with melanin in the hair, thereby lightening the color of the hair.
  • Additional agents such as persulfate salts, may be added to accelerate the process.
  • Imparting a color change or color effect on hair can be done using permanent, demi-permanent, semi-permanent, or temporary hair coloring products.
  • Conventional permanent hair coloring products are dye compositions comprising oxidation dye precursors, which are also known as primary intermediates or couplers. These oxidation dye precursors are colorless or weakly colored compounds which, when combined with oxidizing products, give rise to colored complexes by a process of oxidative condensation.
  • the oxidizing products conventionally use peroxides such as hydrogen peroxide as oxidizing agents.
  • semi-permanent or temporary hair dyeing compositions typically use pigments, liposoluble dyes, or direct dyes chosen from acidic (anionic), basic (cationic), or neutral direct dyes which are deposited onto the hair fiber to impart color to the hair.
  • Direct dyes are nonionic or ionic dyes and colored compounds capable of producing a more or less pronounced change of the natural color of the hair, resistant to shampoo-washing several times. These dyes may or may not be used in the presence of an oxidizing agent.
  • a direct dye is a relatively voluminous molecule that does not penetrate easily into the core of the fiber.
  • Hair lightening or color lifting compositions and hair dyeing compositions possess an alkalinity such that these compositions have a pH value of above 7, typically 9 and above, and may generally require the presence of ammonia or an ammonia gas-generating compound, or other alkalizing agents such as monoethanolamine (MEA) in amounts sufficient to make such compositions alkaline.
  • alkalizing agents cause the hair shaft to swell, helps open up the cuticle, thus allowing the small oxidative dye molecules to penetrate the cuticle and cortex before the oxidation condensation process is completed.
  • the resulting larger-sized colored complexes from the oxidative reaction are then trapped inside the hair fiber, thereby permanently altering the color of the hair.
  • compositions can effectively alter the color of hair
  • these chemical treatments are harsh and are known to cause damage to the hair fibers and decrease the strength of the hair, and may also negatively affect the sensorial properties, such as the smoothness, shine, and/or feel of the hair. Additionally, hair that is damaged during a bleaching and/or dyeing process may not take up color satisfactorily, resulting in unevenness or non-uniformity of color.
  • compositions for altering the color of keratin fibers, particularly human hair that comprise a synergistic combination of various components, including a bonding system comprising a first bonding agent and a second bonding agent.
  • the compositions are typically in the form of a cream, but can also be a serum, a gel, a gel cream, a lotion, a liquid, or the like.
  • the disclosure also relates to methods of using the compositions for altering the color of hair, and methods for reducing and/or preventing damage to hair during a process for altering the color of the hair.
  • the bonding systems disclosed herein when incorporated into hair color-altering compositions, provide integrity properties to keratin fibers subjected to color-altering processes. As such, in addition to lifting or coloring the hair, the compositions disclosed herein can protect hair from damage and/or reduce damage to the hair that would otherwise occur during such processes.

  • Each obtained mixture was respectively applied to a separate pre-bleached hair tress in a bath ratio of 10:1 , allowed to process for about 20 minutes, and then rinsed from the hair. The application process was repeated up to seven times. Each tress was shampooed, and blow dried for about 2 minutes, or until fully dry, between applications and after the final application.

  • FIGS. 6 and 7 The results of elastic modulus and plateau stress of the hair treated in the second testing are shown in FIGS. 6 and 7. As shown in FIG. 6 and FIG. 7, compared to the untreated hair, the hair treated with comparative mixture C1 +D had decreased elastic modulus and plateau stress, indicating that the hair treated with mixture C1 +D was damaged and had impaired integrity due to the chemical treatment for altering the color of the hair. In contrast, the hair treated with mixture 1 G+D did not show decrease in elastic modulus compared to the untreated hair and had a significantly improved plateau stress compared to the untreated hair and the hair treated with mixture C1 +D.

  • compositions 1 1-1 R were evaluated in comparison with comparative compositions C5 and 06, and untreated control hair using Differential Scanning Calorimetry (DSC).
  • DSC Differential Scanning Calorimetry
  • DSC measures the energy transferred to or from a sample undergoing a physical or chemical change. It is useful for investigating the structural characteristics of hair fibers. Keratin undergoes detectable transformations at various temperatures. Changes in these transformation temperatures can be used to estimate how a particular hair-treatment may impact hair fibers.
  • DSC was used to measure denaturation temperature (Td).
  • Denaturation temperature (Td) has been used as a representation of the thermal stability of hair fibers, which is influenced, at least in part, by the cross-link density of the matrix (intermediate filament associated proteins, I FAP). Denaturation temperature (Td) and its relationship in determining the thermal stability of hair fibers is established in the literature. Generally, the denaturation temperature of hair (a-keratin proteins) is higher if the hair strength/integrity is high and vice-versa.

  • Equal amounts of each of the mixtures were applied to separate NL4 hair swatches that were pre-washed with a shampoo five times and air dried. The mixture was allowed to remain on the hair for about 35 minutes at room temperature. Subsequently, the hair was rinsed under running water for about 30 seconds and blow dried for about 30 seconds.
