Definitions

  • Multi-component packaging unit comprising a first preparation (A) with peroxodisulfate, microbial and/or vegetable gum and cellulose (derivative) and a second preparation (B) with carbamide peroxide
  • the present invention is in the field of cosmetics and relates to a multi-component packaging unit (kit of parts) for lightening keratin fibers, which comprises at least two preparations (A) and (B).
  • the first preparation (A) contains at least one peroxodisulfate, at least one microbial and/or vegetable gum and at least one cellulose derivative.
  • the second preparation (B) is characterized by its content of carbamide peroxide.
  • the oxidizing agents contained in bleaching agents are able to lighten the hair fiber through the oxidative destruction of the hair's own pigment, melanin.
  • the oxidizing agent of choice used in branded products is hydrogen peroxide.
  • hydrogen peroxide possibly with the use of ammonia or other alkalizing agents - as the oxidizing agent alone is sufficient, and to achieve a stronger bleaching effect, a mixture of hydrogen peroxide and peroxodisulfate salts and/or peroxomonosulfate salts is usually used.
  • oxidative bleaching products usually consist of at least two components.
  • the first component is an acidic aqueous oxidizing agent preparation with hydrogen peroxide, which is often referred to as a developer solution for short. This is mixed with a bleaching powder shortly before use.
  • the bleaching powder usually contains one or more persoxodisulfate salts and at least one solid alkalizing agent.
  • the hydrogen peroxide content in the aqueous developer solution is usually not more than 12% by weight. Small amounts of other ingredients such as Acidifying agents, complexing agents and stabilizers are included, but the main component of the developer solution is water.
  • the developer solutions Due to the high water content, the developer solutions have to be packaged in relatively voluminous bottles or containers, and more packaging material is also required for the outer packaging. In addition, more space and more energy are used to transport the corresponding products. Since users are placing increasing importance on ecologically sustainable products, people have been looking for hair bleaching products for some time that achieve a sufficiently high bleaching performance, but do not use a water-based developer solution and can therefore be packaged and transported in a resource-saving manner.
  • the developer can be packaged in solid, powder or paste form. This involves using a solid oxidizing agent that is stable and which, when mixed with water, splits off or releases hydrogen peroxide. There are already some approaches to this type of packaging in the state of the art.
  • DE 10 2016 219 868 A1 proposes a bleaching agent based on two solid components, with both components each being packed in a chamber of a water-soluble pouch.
  • the first component contains potassium peroxodisulfate and ammonium peroxodisulfate
  • the second component comprises a solid oxidizing agent from the group of percarbamide, percarbonate and perborate. To produce the ready-to-use agent, this two-chamber bag is placed in water.
  • the first agent is urea peroxide (i.e. carbamide peroxide or percarbamide)
  • the second agent is a bleaching powder with persalts, an alkaline salt, methylcellulose and a polyvinylpyrrolidone polymer.
  • the two components of the bleaching agent are pressed into a multi-layer tablet, which contains persulfates in a first layer and a hydrogen peroxide releaser (including urea peroxide) in a second layer.
  • This tablet is dissolved in water for use.
  • a multi-component packaging unit with two separate preparations (A) and (B) is used for bleaching, wherein the preparation (A) contains the combination of at least one peroxodisulfate (a1), at least one gum from the group of microbial gums and/or vegetable gums (a2) and cellulose and/or a derivative of cellulose (a3), and the composition (B) contains carbamide peroxide.
  • the preparation (A) contains the combination of at least one peroxodisulfate (a1), at least one gum from the group of microbial gums and/or vegetable gums (a2) and cellulose and/or a derivative of cellulose (a3)

This includes in particular the color changes known under the terms lightening, bleaching and bleaching.
  • the lighter coloring of the hair is caused by the oxidizing agent(s) present in the agent.
  • the agents according to the invention can also contain coloring components, such as oxidation dye precursors and/or direct dyes, for the purpose of shading. The color loss of the resulting coloring can be easily modified by the coloring components.
  • these coloring components are contained in the product in such small quantities that the color impression of the keratin fibers treated with the product is still lighter than their original color.
  • Corresponding coloring techniques can be referred to as coloring bleaching or nuanced bleaching.
  • the multi-component packaging unit according to the invention comprises the two separate preparations (A) and (B).
  • the first preparation (A) contains the peroxodisulfates and can be solid, powdery or pasty. In short, preparation (A) can also be referred to as bleaching powder or bleaching paste.
