Definitions

  • the present invention relates to an agent for altering the color of keratinous substrates, including human keratin fibers such as the hair.
  • the agent for altering the color of keratin fibers comprises a fatty substance, a rheology modifying polymer, direct dyes, optionally, oxidative dyes and optionally, an oxidizing agent.
  • Conventional hair coloring products include permanent hair dyeing products, also known as oxidation dyeing, which use the combination of compositions containing oxidative dye precursors, also known as primary intermediates or oxidation bases, and oxidizing products containing oxidizing agents such as peroxide and persulfate compounds, under alkaline pH conditions in the vast majority of cases.
  • the oxidation dye precursors comprise oxidation bases chosen from ortho- or para-phenylenediamines , ortho- or para-aminophenols , and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds, which, when combined with oxidizing products, can give access to colored species via a process of oxidative condensation.
  • the shades obtained with these oxidation bases may often be varied by combining them with at least one coupler chosen, for example, from aromatic meta-diamines , meta- aminophenols , meta-diphenols , and certain heterocyclic compounds, such as indole compounds.
  • couplers chosen, for example, from aromatic meta-diamines , meta- aminophenols , meta-diphenols , and certain heterocyclic compounds, such as indole compounds.
  • the variety of molecules used as oxidation bases and couplers can allow a wide range of colors to be obtained.
  • Oxidative coloring compositions typically contain aqueous ammonia as an alkalizing agent and for activating the oxidizing agent. These alkalizing agents also 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.
  • aqueous ammonia as an alkalizing agent and for activating the oxidizing agent.
  • These alkalizing agents also 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.
  • the use of ammonia may affect the user, not only because of the undesirable odor of ammonia, but because it may also pose greater risks of intole
  • direct dyeing it is also known practice to dye keratin fibers by direct dyeing.
  • the process conventionally used in direct dyeing comprises applying to the keratin fibers direct dyes, which are colored and coloring molecules that have affinity for the fibers, leaving the dyes to act in order to allow the colored molecules to penetrate, by diffusion, into the hair, and then rinsing the fibers .
  • direct dye compositions may be used without the obligatory presence of an oxidizing agent.
  • these direct dyeing operations may be performed repeatedly without degrading the keratin fiber.
  • the leave-on time of a direct dye composition conventionally ranges from 15 to 45 minutes, depending on the nature of the fiber (sensitized or non-sensitized) and the nature of the dye used.
  • a great deal of research has been conducted on reducing the leave-on time of dye compositions without, however, increasing the concentration of the constituents, while at the same time maintaining a good level of dyeing, i.e., good dyeing power and good fastness of the color with respect to external agents and over time.
  • compositions can be provided in the form of a liquid emulsion, such as a liquid-lotion, liquid-gel, liquid-cream, or a cream emulsion, such as a thick cream or gel-cream, or a foam or mousse wherein the liquid emulsion form has a thinner consistency than the cream emulsion form and is typically packaged in a bottle.
  • a liquid emulsion such as a liquid-lotion, liquid-gel, liquid-cream, or a cream emulsion, such as a thick cream or gel-cream, or a foam or mousse
  • the liquid emulsion form is generally employed when the entire head of hair is to be colored or when only one color is desired since the dye composition spreads easily, allowing for greater coverage while the cream emulsion form can be employed for dyeing the entire head of hair and for highlighting or lightening only certain sections of the hair.
  • the objective of the present invention is to obtain novel compositions for oxidatively dyeing the hair.
