Abstract: The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursors 2-(1,3-benzodioxol-5-ylamino)ethanol and 1-phenyl-3-methylpyrazol-5-one in combination with at least one oxidation base.

Abstract: A method for providing an electronic bill payment platform utilizing a distributed ledger is disclosed. The method includes receiving a request from a first user, the request including a payment request corresponding to a statement of charges; identifying, from a node, data corresponding to the request in the distributed ledger; initiating a first payment transaction based on the identified data and the request, the first payment transaction including a first debit from a user account to a holding account; initiating a second payment transaction based on the identified data and the request, the second payment transaction including a second debit from the holding account to a biller account; and updating, in the at least one node, the distributed ledger based on information corresponding to at least one from among the at least one request, the first payment transaction, and the second payment transaction.

Abstract: A system and method for dyeing and/or lightening keratin-containing fibers, as well as a lightening composition for use in such a system and method are described, which are able to provide a high levels of lift while avoiding irritation and/or soothing the scalp. The system and method include a first composition, which may be a lightening composition. That composition includes (i) at least two alkali components for lightening keratin-containing fibers, wherein one of the at least two alkali components comprises sodium metasilicate and/or a metasilicate salt, and the composition comprises about 0.1 to about 10 weight percent of the at least two alkali components; and (ii) an arginine compound, wherein the arginine compound is present in an amount that would be effective to reduce irritation to a surface of a mammal having keratin-containing fibers. The system and method also include an oxidizing agent composition comprising an oxidizing agent, wherein the system has a pH of at least about 9 to about 12.
