  • Oxidative hair lightening or hair coloring composition having improved performance properties
    Patent number: 11464729
    Abstract: The subject matter of the present disclosure are agents for oxidative hair lightening or hair coloring, containing 70-90% by weight of a total of % water, oxidation dye precursor(s), alkalizing agent(s), and a certain mixture of a crosslinked copolymer of acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols, anionic surfactant, cationic or zwitterionic polymer and linear, saturated C8-C22 alkan-1-ol, and sodium polyacrylate, giving the whitening or coloring agent an application-optimal viscosity and the consistency of a gel-like cream with an excellent feel.
    Type: Grant
    Filed: June 14, 2019
    Date of Patent: October 11, 2022
    Assignee: HENKEL AG & CO. KGAA
    Inventors: Juergen Schoepgens, Christa Rohland, Gabriele Weser
  • Cold manufactured oxidative hair lightening or hair coloring composition for Level 2 colors
    Patent number: 11458078
    Abstract: The subject matter of the present disclosure are agents for oxidative hair lightening or hair coloring, containing from about 70-90% by weight of a total of % of water, alkalizing agent, optionally a colorant, and a certain mixture of a cross-linked copolymer of acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols, anionic surfactant and linear, saturated C8-C22 alkan-1-ol, and sodium polyacrylate, whereby the brightening or coloring agent obtains an application-technically optimal viscosity and the consistency of a gel-like cream with an excellent haptics.
