Abstract: Colorants, in particular hair colorants, frequently contain ammonia, which leads to an unpleasant odor during use and can irritate skin, hair and the lungs. In the case of known alternatives to ammonia, the coloring performance or the durability of the color is frequently weaker. This problem is solved by proposing a colorant which comprises an alkalizing agent to open the cuticle layer of hair and/or to swell hair and/or skin, wherein the alkalizing agent comprises or consists of particles of bioactive glass as alkalizing agent.

Abstract: Disclosed is an additive manufacturing method for producing a bio-mimetic nanocomposite scaffold using a multi-dimensional printer. The method includes generating a bio-mimetic tool path for a given connective tissue; receiving a bio-mimetic nanocomposite printable material into one or more printing heads of the multi-dimensional printer; and dispensing the bio-mimetic nanocomposite printable material in one or more layers on a printing surface, based on the generated bio-mimetic tool path, for producing the bio-mimetic nanocomposite scaffold.

Abstract: The present disclosure generally relates to the use of certain compounds, such as anthocyanins, saponins, or combinations thereof, at low concentrations to improve the aqueous solubility of flavonoid compounds. Thus, in certain aspects, the disclosure provides aqueous compositions including flavonoid compounds, such as naringenin or phloretin, and one or more compounds selected rom anthocyanin compounds, saponins, and combinations thereof. In related aspects, the disclosure provides methods and uses of certain compounds, such as anthocyanins, saponins, or combinations thereof, to enhance the aqueous solubility of flavonoid compounds. In related aspects, the disclosure provides methods to maintain the stability of a supersaturated aqueous solution of flavonoid compounds, for example, by increasing the kinetic stability of such supersaturated aqueous solutions.

Abstract: The present application relates to an aqueous method for the preparation of microgel particles using a stimuli-responsive prepolymer
