According to GlobalData’s company profile on Henkel, Nanoemulsion cosmetics was a key innovation area identified from patents. Henkel's grant share as of February 2024 was 50%. Grant share is based on the ratio of number of grants to total number of patents.
A granted patent (Publication Number: US11918665B2) outlines a process for dyeing keratinous material using specific agents. The process involves applying an agent (a) containing organic silicon compounds and colorant compounds to the keratinous material, followed by the application of an agent (b) containing sealing reagents. The organic silicon compounds in agent (a) are selected from various formulas and specific compounds such as (3-Aminopropyl)triethoxysilane and (2-Aminoethyl)trimethoxysilane. The process also includes the use of effect pigments with substrate platelets and coatings comprising metal oxides and coloring compounds.
Furthermore, the patent details the composition of the agents, including organic silicon compounds like Methyltrimethoxysilane and Ethyltriethoxysilane. The process allows for the use of multiple structurally different organic silicon compounds in agent (a) and emphasizes the particle size of the colorant compound. Additionally, a kit-of-parts for dyeing keratinous material is described, containing separately packaged agents for efficient application. The patent also highlights the importance of water content in the agents and the timing of application to achieve desired results in dyeing keratinous material effectively.
