A toothpaste composition includes a structurant and a thickener, wherein the toothpaste composition has a predetermined viscosity and phase angle by using the structurant instead of reducing the content of a thickener, and thereby has an improved release property during use while maintaining a shape retention property of the toothpaste, and has an improved feeling of refreshment, flavor releasing power, cleaning power, and stain removal power. Further, provided is a toothpaste composition including a chelating agent containing phosphate and silica, wherein the chelating agent is supersaturated to precipitate phosphate to provide strong cleaning power, a whitening effect, a stain removal effect, and a crunchy sensation. Further, provided is a toothpaste composition including a peroxide, a thickener, and a spreading agent, wherein the peroxide and the thickener are separated from each other, providing excellent sense of use, stability, and a whitening effect in an anhydrous state.

Described herein are compositions and methods for the treatment of meibomian gland dysfunction. Said compositions and methods comprise keratolytic agents, such as salicylic acid, selenium disulfide, or the like. Topical administration of said compositions to the eyelid margin or surrounding areas provides therapeutic benefit to patients suffering from meibomian gland dysfunction.

Methods are described that provide controlled release of beneficial bacteria to the oral cavity. Such bacteria can subsequently colonize the oral cavity and displace or suppress the growth of pathogenic microorganisms. Described devices include a stabilized preparation of such beneficial bacteria and provide a consumable liquid, wet foam, or gel that includes such bacteria when used.

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.

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.
