This invention provides particles encapsulating colorant that do not produce functional effects or remove functional effects until they are triggered by contacting with at least one exogenous source. The particles in this invention minimize toxic effects the body of the colorant and the material that interacts with an exogenous source as well as minimize body chemicals from degrading both the colorant and the material that interacts with an exogenous source inside the particle.

Provided are: a hydrophilized organic powder that is obtained by a hydrophilization treatment of a hydrophobic organic powder and has favorable properties; and a cosmetic that includes the hydrophilized organic powder. A hydrophilized organic powder that has a hydrophilizing-coat of polyoxyethylene (10) isostearyl ether on a hydrophobic organic powder is provided. Further, a cosmetic that includes the hydrophilized organic powder is provided. The hydrophobic organic powder is preferably an organic resin powder or a metallic soap powder, or a combination thereof.

The present invention relates to a glitter comprising a foil coated with metal pigments, more particularly aluminium pigments, to a method for producing it, to the use thereof in cosmetic products, coating materials such as paints, varnishes and printing inks, for example, and in adhesives and modelling and/or moulding compositions, and also to cosmetic products, coating materials and adhesives, and modelling and/or moulding compositions which comprise the glitter.

Provided are coated particles and methods of their use for providing healthcare benefits. More specifically, the present invention provides amino acid and/or polymer-coated particles, or particles coated with other materials, for binding to, or otherwise associating with, surfaces of the oral cavity.

The present invention relates to a composition according to the present invention comprises: (a) at least one particle comprising at least one cationic polymer, at least one anionic polymer, and at least one non-polymeric acid having two or more pKa values or salt(s) thereof; and (b) at least one physiologically acceptable volatile medium. The composition according to the present invention is stable, and can have a variety of cosmetic functions. For example, the composition according to the present invention can prepare a film which can have cosmetic effects such as absorbing or adsorbing malodor, changing the appearance of a keratin substrate such as skin, changing the feel to the touch of the keratin substrate, and/or protecting the keratin substrate from, for example, dirt or pollutants.

Microparticles based on ester derivatives of hyaluronan and related methods and compositions are disclosed. The microparticles comprise a conjugate of all-trans retinoic acid and a particular hyaluronan comprising from 1 to 5000 dimer units; where the microparticles comprise a degree of substitution of all-trans retinoic acid residues in the conjugate of hyaluronan in the range of from 0.1 to 8%. Methods of preparing the microparticles and related compositions are also disclosed.

Provided is a cosmetic containing a composite particle containing a starch alkenyl succinate metal salt coated with 0.05 to 2 parts by mass of zinc oxide to 1 part by mass of the starch alkenyl succinate metal salt. The starch alkenyl succinate metal salt may be at least one selected from the group consisting of a starch octenyl succinate metal salt, a starch decenyl succinate metal salt, a starch dodecenyl succinate metal salt, a starch tetradecenyl succinate metal salt, a starch hexadecenyl succinate metal salt, and a starch octadecenyl succinate metal salt.

Compositions and methods of manufacture for an extended time-release fragrance comprising volatile organic compounds. A composition of the disclosure includes an effective amount of a volatile organic compound for providing a fragrance that can be sensed by a user and fractionated coconut oil comprising caprylic acid and capric acid.

The invention relates to a process for preparing PCL-comprising microparticles, to microparticles obtainable by said process, to gel hence obtained and to several uses of the gel such as for the preparation of a medicament for treating a skin abnormality or disfigurement, and/or for controlling bladder function and/or controlling gastric reflux and/or for treating erectile dysfunction and/or for treating vocal cords. The gel may also be used for cosmetic applications.

An aqueous cosmetic comprising: at least one nature-derived polysaccharide comprising as constituent monosaccharides, glucuronic acid and one cyclic form of an aldohexose, a particulate copolymer, the particulate copolymer obtained from at least two monomer units selected from the group consisting of a monomer comprising an ethylenic unsaturated group and a benzene skeleton and a monomer comprising a (meth)acryloyl group; an anionic surfactant; and from 50 to 95 wt % of water of the weight of aqueous cosmetic.
