An aqueous oxidizing compositions comprising one or more amino acids and hydrogen peroxide are described. The aqueous oxidizing compositions reduce hair damage during chemical services. The effect of hair damage reduction was found to be further improved when polycarboxylic acids were added to bleaching powder, oxidative dyeing, and permanent waving compositions.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair, comprising the following steps: applying an agent (a) to the keratinous material, wherein the agent (a) comprises: (a1) at least one organic silicon compound selected from the group of silanes having one, two or three silicon atoms, and

(a2) at least one coloring compound comprising at least one effect pigment comprising α) a substrate platelet and β) a coating, wherein the coating comprises at least one layer that has been wet-chemically prepared using a metal alkoxide and an organosilicon compound having a basic group; and applying an agent (b) to the keratinous material, wherein the agent (b) comprises: (b1) at least one sealing reagent.

The present invention relates to a composition and a kit of parts for antimicrobial photodynamic therapy and uses of the same, the composition comprising (a) hydrogen peroxide, carbamide peroxide and/or sodium hypochlorite and (b) at least one photosensitizer capable of being activated by light emitted in the blue spectrum, in particular curcumin, riboflavin and erythrosine.

The invention provides compositions, methods and kits for the removal of harmful or irritating substances from bodily surfaces. Kits may include a composition containing capsaicin and a capsaicin-cleansing composition, e.g., a composition in which capsaicin is soluble.

Processes and a multi-component packaging unit (kit-of-parts) are provided for decolorizing keratinous material which has been colored by the application of at least one pigment. A process includes applying to the keratinous material a decolorizing agent comprising at least one anionic surfactant, and having a pH value of 1.0 to 3.5, and rinsing the decolorization agent from the keratinous material after a contact time.

The invention relates to a method of customizing a nail-biting and/or finger sucking treatment solution, and a kit for providing a nail-biting and finger sucking treatment that is customizable for a wide range of afflicted users seeking to break a persistent nail-biting and/or finger sucking habit. In exemplary embodiments, the composition kit includes two separate containers, a first container having a nail growth-promoting, waterproofing composition that may be applied directly on a user's nails; and a second container may include an additive for customizing a bitterness factor of the first composition. Typically, the first container includes an applicator such as a brush. To facilitate adding the additive in a manner that is easily customizable, the second container may include a dropper for adding small doses of the additive composition to the first composition. The customizable kit allows the user to safely adjust the bitterness so that the treatment remains effective.

Provided is a kit or system (100) for preparing a peroxide composition with increased viscosity with a pH in the range of 7 to 12 in an almost instantaneous method. For example, the kit or system may be used to provide an almost instantly obtainable (hydro)gelled peroxide composition. The system comprises a first aqueous composition (102) comprising a peroxide agent. The first aqueous composition has a first pH of less than 7. The system further comprises a second composition (104) comprising a basic agent. The second composition is separate from the first aqueous composition. A pH induced thickener is included in the kit or system separate from the second composition. The peroxide composition is obtainable by combining the parts of the kit or system. The pH induced thickener is capable of increasing the viscosity of the peroxide composition upon subjecting it to the pH in the range of 7 to 12. The kit or system has sufficient basic agent for the peroxide composition to cause the pH in the range of 7 to 12. A method for preparation and use of the kit or system is also provided.

Disclosed is the use of certain alkanolamines for use in hair treatment compositions as a replacement for some or all ammonium hydroxide. When used as hair colorant alkalizers, these derivatives demonstrate reduced hair fiber damage, effective color lifting, and significant improvement in cytotoxicity and malodor compared to well known replacements for ammonium hydroxide.

Method for treating hair comprising the successive application onto hair of polymeric layers which can be removed to a large extent or even totally in an easy manner upon request of the user by using a cationic surfactant.

The present invention relates to a process for treating keratin fibers, comprising the application to the keratin fibers of a composition (C) comprising at least one (poly)carbodiimide compound, at least one aqueous dispersion of particles of polymer(s) chosen from polyurethanes, acrylic polymers, and mixtures thereof, optionally at least one silicone, and at least one coloring agent chosen from pigments, direct dyes, and mixtures thereof.
