The invention relates to a hair colouring and/or bleaching composition comprising at least a first aqueous component (i) and a second aqueous component (ii) being mixed prior to application onto hair, wherein the first component (i) or the second component (ii) or both components (i) and (ii) comprise a gel-network system consisting of multi-lamellar sheets and vesicles with d-spacing (interlayer spacing between sheets) between 5 nm and 50 nm, preferably 10 nm to 30 nm, more preferred 15 nm to 25 nm as measured by Small Angle X-Ray Scattering (SAXS), and the first component (i) or the second component (ii) or both comprise at least a first malodor suppressant being a compound having a distribution coefficient log P of 2 or more and a molecular weight of between 100 and 400, a method for coloring or bleaching hair, a kit comprising the above components and the use of the described hair coloring composition for colouring and/or bleaching hair with a reduced or eliminated ammonia odour.

Dental pastes are provided which include: (i) a compound of Formula (I), (ii) a compound of Formula (II) or a pharmaceutically acceptable salt thereof, and (iii) a dental abrasive.

A portable, hand-held electrospinning or electrospraying apparatus and system, method, and portions thereof, comprised of a durable portion of the hand-held apparatus and a consumable portion of the hand-held apparatus. The consumable portion of the hand-held apparatus, which may contain the solution to be output in electrospin or electrospray fashion, may be replaced in whole or in part to provide additional or alternative solution. A base station may be provided, and can output high voltage and communication signals to the hand-held apparatus to enable the electrospin or electrospray operation by the hand-held apparatus.

A tooth whitening kit and method of whitening teeth using the same. The method may include applying a tooth whitening composition directly to surfaces of a user's teeth, exposing the surfaces of the user's teeth to ambient air for a first period of time to form a film of the tooth whitening composition on the surfaces of the user's teeth, applying light to the surfaces of the user's teeth for a second period of time while the film of the tooth whitening composition remains on the surfaces of the user's teeth, ceasing application of the light to the surfaces of the user's teeth and leaving the film of the tooth whitening composition on the surfaces of the user's teeth for a third period of time, and removing the film of the tooth whitening composition from the surfaces of the user's teeth.

A treatment application garment, such as a glove or a sock, is disclosed. The garment allows for various treatments directed toward the fingers and toes, such as the fingernails and toenails. For example, each digit of the garment may contain an absorbent pad containing acetone. The hand or foot is inserted into the garment such that the nail is positioned below the absorbent pad containing the acetone, allowing the acetone to be constantly applied to the nail to remove polish therefrom. After the treatment is complete, the glove may be removed and the open end thereof tied off, thereby containing the acetone and the smell thereof within the glove. Other features and treatments are also disclosed.

A cosmetic product includes an O/W emulsion of a crosslinked silicone obtained from radical polymerization under emulsion polymerization reaction condition of at least one polyorganosiloxane having at least two aliphatic unsaturated carbon-carbon bonds, and optionally an organohydrogenpolysiloxane, in the presence of a polyether-modified polysiloxane. It is used in a making-up method.

The invention relates to an anhydrous cosmetic or dermatological formulation comprising a viscose lipid-containing preparation and propellant gas consisting essentially of one or more substances selected from hydrofluorocarbons, n-butane, isobutane and propane. The formulation permits application to the skin by spraying of an otherwise nonsprayable preparation. The formulation is free from readily volatile solvents, surfactants, and preferably free from silicones.

A tooth whitening and/or tooth sensitivity strip or film comprising: about 1-20 wt. % hydroxyapatite (HAP). A process for the manufacture of a tooth whitening strip or film, the process comprising at least the steps of: —mixing at least one or a combination of polyvinylpyrrolidone (PVP) polymers wherein the amount of the polyvinylpyrrolidone (PVP) polymers is greater than 75 wt. % of the film or strip; and —an amount at least about 1-20 wt. % hydroxyapatite (HAP); and —at least one or a combination of polycarbophils; —with water to provide an aqueous tooth whitening liquid; —applying the aqueous tooth whitening liquid to a substrate to provide a substrate carrying the aqueous tooth whitening liquid; —drying the aqueous tooth whitening liquid to provide a tooth whitening film on the substrate, said film having a thickness from about 50 pm to about 500 pm.

A method for producing a carbon dioxide-containing hydrogel article including (1) to (3). (1) Preparing an article including a hydrogel that contains a water-soluble polymer, a cross-linking agent for the water-soluble polymer, and water, wherein a loss tangent of the hydrogel at 1 Hz in dynamic viscoelasticity measurement is 0.46 or greater. (2) Adjusting a composition of an ambient atmosphere of the article including the hydrogel such that a carbon dioxide gas concentration in the ambient atmosphere becomes 10 vol% or greater, and sealing the article including the hydrogel inside a package. (3) Making cross-linking of the hydrogel proceed until the loss tangent, at 1 Hz in dynamic viscoelasticity measurement, of the hydrogel in the article including the hydrogel becomes less than 0.46, and thereby obtaining a carbon dioxide-containing hydrogel article sealed inside the package.

Described herein is an oral care implement comprising: a handle; and a head coupled to the handle, the head comprising a main body and a release component coupled to the main body, the release component comprising: a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 130° C.; and a release agent comprising at least one of zinc oxide, potassium nitrate, and tetrapotassium pyrophosphate; wherein the release agent is dispersed throughout the water-dissolvable matrix.
