A method of whitening teeth. The method may include delivering a buffer solution from a reservoir of a toothbrush to one or more tooth cleaning elements of the toothbrush; applying a toothpaste containing a peroxide to the tooth cleaning elements, the toothpaste having a first pH; and brushing the teeth with the tooth cleaning elements, thereby mixing the buffer solution and the toothpaste to form, at surfaces of the teeth, a tooth whitening mixture having a second pH that is greater than the first pH.

The present invention generally relates to the field of skin care. More particularly, the invention relates to a cosmetic or therapeutic skin care composition comprising live bacteria of at least one Cutibacterium acnes (C. acnes) strain in combination with a thickener that specifically supports their viability during storage and/or their ability to replicate after application to the skin. Preferably, the cosmetic or therapeutic skin care composition comprises bacteria of at least one C. acnes strain selected from the group consisting of D1, A5, C1, C3, H1, H2, H3, K1, K2, K4, K6, K8, K9, L1, and F4. The invention also provides a method for treating or preventing acne by applying the skin care composition of the invention to a skin area in need of treatment. The invention also relates to the use of a skin care composition of the invention for treating or preventing acne.

A cosmetic composition is provided including a brassica amidoalkyl compound which emits a malodor, a malodor suppressant which is Hydrogenated Castor Oil/Sebacic Acid Copolymer; and a cosmetically acceptable carrier.

Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.

The present invention relates generally to: a composition comprising or consisting at least one avenanthramide or an analogue thereof or an oat extract comprising an avenanthramide or an analogue thereof with an improved stability; its cosmetic or medical use; the use of such composition for the preparation of foods, food supplements, cosmetic, pharmaceutical or veterinary preparations; and foods, food supplements, cosmetic, pharmaceutical or veterinary preparations comprising such a composition. Finally, the present invention relates to specific stabilizers for the stabilisation of avenanthramide(s).

This disclosure relates to a cosmetic composition capable of preventing enzyme damage, and a cosmetic container for storing the same. One aspect of this disclosure provides a cosmetic composition capable of preventing enzyme damage, the composition including a first content disposed in a first space; a second content which is disposed in a second space separated from the first space, and which includes an enzyme and a polyol, wherein a cosmetic material is produced by mixing the first content and the second content.

Disclosed is a method for using a two-step cosmetic product, such as used on the lips, that includes the use of a basecoat that utilizes a surface-stabilized dispersion of copolymer particles and a styrenic block copolymer, and a top coat that utilizes a silicone amine and a viscous silicone, and where the composition(s) are configured to allow the silicone amine to react with the maleic anhydride after the top coat is applied.

This disclosure relates to a printing device for printing or dispensing a curable printing composition which is capable of changing color in response to the application of a magnetic field in the non-cured state. The printing device may be a handheld device such as a portable pen. The present disclosure further relates to curable compositions, cartridges and methods which may be used in combination with the aforementioned printing devices or in other applications.

Provided are: a core-corona polymer particle excellent in emulsion stability and feeling of use, and a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising the particle. Certain embodiments of the present invention provides a core-corona polymer particle obtained by radical-polymerizing a polyethylene oxide macromonomer represented by formula (1) and one or two or more of hydrophobic monomers represented by formulas (2) and (3) under conditions (A) to (D).

A sunscreen composition is an oil-in-water emulsion of aqueous and oil phases and includes at least one lipophilic acrylate-based oil thickener, at least one mineral UV filter, and at least one nonionic surfactant that is a polyethylene glycol ethers of fatty acids or polyethylene glycol esters of fatty acids, or a combination thereof. The sunscreen composition may also include one or a combination of ingredients selected from the group consisting of solvents, SPF boosters, humectants, skin care actives, oils, waxes, thickeners, preservatives, pH adjusters, chelating agents, viscosity adjusters, cooling agents, fillers, fragrances, dyes, pigments, and combinations thereof. The sunscreen composition has an SPF in a range from about 30 to about 55 and exhibits phase stability and processibility.
