Definitions

  • the present application relates to cosmetic compositions for use on keratinous substrates, such as keratin fibers.
  • cosmetic compositions for use on keratinous substrates such as keratin fibers.
  • compositions and methods for treating bleached or lightened hair are particularly relevant to cosmetic compositions for use on keratinous substrates, such as keratin fibers.
  • the process of changing the color of hair can involve depositing an artificial color onto the hair which provides a different shade or color to the hair and/or lifting the color of the hair, such as lightening the color of dark hair to lighter shades.
  • the process of lifting the color of hair which can either involve lightening or bleaching (greater degree of lightening), generally requires the use of compositions that comprise at least one oxidizing agent.
  • colorants or dye compounds such as oxidation dye precursors and direct dyes are present in these compositions, such compositions can change or deposit color and lighten the color of hair at the same time.
  • Conventional hair coloring products are permanent 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 agents, give rise to colored complexes by a process of oxidative condensation.
  • 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 being at pH 9 and above, and may generally require the presence of basic compounds such as ammonia or an ammonia gas generating compound and/or an amine or ammonium-based compound in amounts sufficient to make such compositions alkaline.
  • basic compounds such as ammonia or an ammonia gas generating compound and/or an amine or ammonium-based compound in amounts sufficient to make such compositions alkaline.
  • Such compounds cause the hair shaft to swell, 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.
  • hair dyeing and/or color lifting compositions can effectively alter the color of hair, these compositions can damage the hair fibers, making the hair dry, coarse or dull, especially in fragile areas, and more particularly at the ends leading to split ends. Under such circumstances, hair can also become less manageable, more frizzy, and less disciplined, and more difficult to style or shape.
  • bleaching of hair an undesirable or unwanted yellowish tint or hue on hair is often observed. Even when the hair is dyed, this yellowish tint may still be observable to a lesser degree. It would thus be desirable for manufacturers in the cosmetic industry to create products that mask the yellowing effect of lightening products such as bleaches.
  • hair styling products for example, leave-in gels and creams which employ ingredients such as film forming polymers that impart desirable styling or shaping hold while on the hair.
  • ingredients such as film forming polymers that impart desirable styling or shaping hold while on the hair.
  • some ingredients can be easily removed from the hair, for example by rinsing or washing.
  • any cosmetic benefits to the hair from such products are generally diminished or removed once the hair is rinsed or washed.
  • alkaline composition Another type of composition that can be applied onto hair in order to change its shape and make it more manageable is an alkaline composition that is found in commercial hair relaxers or hair straighteners. These products can confer longer lasting shape or style to the hair.
  • Alkaline hair relaxing/straightening involves hydrolyzing the keratin of the hair with various alkaline agents, such as inorganic hydroxides, for instance sodium hydroxide, or organic hydroxides, such as guanidine hydroxide, or organic amines.
  • Hair relaxing/straightening products that employ sodium hydroxide or potassium hydroxide are also called lye-based products and products that use other alkaline agents such as lithium hydroxide, calcium hydroxide, organic hydroxides and other non-hydroxide compounds, for example, organic amines, generally fall under the category of no-lye products. While such products can effectively straighten or shape hair, these products can damage the hair by weakening and/or causing dryness of the hair fibers
  • compositions and methods that can lead to more effective and desirable hair lightening and coloring effects, while providing other cosmetic advantages such as manageability, conditioning, and shaping/styling benefits to hair.
  • a hair cosmetic composition with ingredients that can effectively mask the yellow tint on bleached/lightened hair and at the same time, impart good styling/shaping or straightening benefits as well as enhanced hair caring and manageability properties and other cosmetic properties such as volume control/reduction, frizz control/reduction, discipline (less fly-aways), and regularity of shape.
  • the present invention is directed to a hair cosmetic agent composition, the composition comprising:
  • thiol-based compound selected from thiolactic acid, thiolactic acid derivatives, their salts, and mixtures thereof;

  • the present invention is also directed to processes for treating the hair involving the application of the above-described composition onto hair, and optionally, heating the treated hair at a temperature of equal to or greater than 50 Q C.
  • Figure 1 provides images of hair swatches contacted with inventive and comparative formulas according to Protocol I (with heat) and Protocol (without heat).
  • compositions effectively condition the hair and provide manageability properties to hair, including one or more of straightening effects; frizz control; volume reduction or volume control; styling or shaping effects; curling effects; texlaxing effects or reduction/loosening of curls; improvement or retention of curl definition; humidity resistance; cosmeticity to the feel; smooth feel; natural feel; less or reduced rough ends; and/or improvement of the appearance of hair.
