A sunscreen composition comprised of one or more sunscreen active agents encapsulated in a cellulose derived capsule wherein the composition can contain one or more additional agents. A sunscreen composition can be mixed with a bodywash, shampoo, conditioner, lotion, gel, soap, cream, hand sanitizer, spray or mousse and can be used by an individual during their normal hygiene processes, such as during a shower or bath or while applying a body product to their skin or hair.

The present invention relates to a composition comprising: (a) at least one pigment; (b) at least one first copolymer of at least two monomers selected from (meth)acrylic acid, esters thereof, and salts thereof; (c) at least one second copolymer of styrene or -methylstyrene and of at least one monomer selected from (meth)acrylic acid, esters thereof, and salts thereof, wherein the weight ratio of the amount of the (c) second copolymer(s)/the amount of the (a) pigment(s) is 1.0 or more, preferably 1.5 or more, and more preferably 2.0 or more, and the composition comprises at least one non-ionic surfactant in an amount of 0.5% by weight or less, preferably 0.3% by weight or less, and more preferably 0.1% by weight or less, relative to the total weight of the composition, or the composition comprises no non-ionic surfactant. The composition according to the present invention is suitable for a keratin substance such as the skin and the surface of a mucous membrane, and can provide the keratin substance with enhanced or improved cosmetic effects, such as better concealing effects of the original color of the keratin substance, as well as long-lasting makeup effects.

A process for producing porous particles of a polyhydroxyalkanoate (PHA) includes the following steps: providing a spray drying atomization chamber heated to an operating temperature comprised between 50 C. and 300 C.; providing an aqueous suspension having the PHA and an expanding agent which decomposes at the operating temperature of the atomization chamber, with the formation of at least one gaseous compound; and injecting the aqueous suspension into the atomization chamber provided at the operating temperature, so as to cause instantaneous evaporation of the aqueous suspension and decomposition of the expanding agent, with formation of the porous PHA particles. The particles obtained from said process can be used to obtain cosmetic compositions that are soft to the touch, with high oil absorbing capacities and high flow index, able to generate a uniform, filling effect for wrinkles and skin furrows, making the skin more glossy and compact.

Oral care compositions including peroxide, alumina, and optionally water. Dentifrice compositions including peroxide, alumina, and optionally water. Dentifrice compositions including peroxide, calcined alumina, and optionally water. Dentifrice compositions including peroxide, calcined alumina, uncalcined alumina, and optionally water. Methods of use to whiten teeth using one or more of the disclosed compositions.

A microneedle particle arranged to be rolled and massaged on a subject's skin to penetrate the stratum corneum is disclosed. The microparticle comprises a support body, and a plurality of microneedles protruding from the support body (20), each microneedle comprising a tip. The support body maintains the microneedles and tips in a predetermined conformation allowing the microneedle particle to be rolled on the skin. The microneedles have an average tip sharpness radius of less than 20 m, an average microneedle length of less than 100 m, and an average tip sharpness to microneedle length ratio of 1:5 to 1:200. Formulations and kits for said use are provided. A microneedle particle manufacturing method using a non-linear two-photon absorption process, a non-therapeutic cosmetic method of skin treatment, and a method of drug delivery through the skin for said microneedle particle are disclosed.

A method for increasing the specific surface area of titanium phosphate plate-shaped particles of this invention includes: obtaining a liquid in a state where a powder containing titanium phosphate plate-shaped particles is dispersed in an aqueous alkaline solution.
