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 an oil-in-water type pest repellent composition containing the following components (A) to (C): (A) 13% by mass or more and 50% by mass or less of at least one non-volatile liquid oily component selected from the group consisting of a silicone oil, an ester oil, an ether oil, a hydrocarbon oil, an aliphatic alcohol, and a polyhydric alcohol, the non-volatile liquid oily component having a surface tension at 25° C. of 40 mN/m or less and a viscosity at 23° C. as measured with a B-type rotational viscometer of 400 mPa.Math.s or less; (B) 0.5% by mass or more and 35% by mass or less of hydrophobic particles having a volume median particle diameter of 0.1 μm or more and 40 μm or less; and (C) 30% by mass or more and 86.5% by mass or less of water.

A composite particle includes a core particle having a pore and fine fibers inseparably bonded to a surface of the core particle. The fine fibers are at least either cellulose nanofibers or chitin nanofibers.

Alkali-swellable rheology modifier comprising a core-shell polymer comprising a core polymer and a shell comprising at least one shell copolymer layer at least partially cross-linked and containing a mole percent of crosslinking agent greater than the mole percent of crosslinking agent in the core polymer, provided if the mole percent of crosslinking agent in the core polymer is zero, then either the core polymer is greater than 60 wt % of the core-shell polymer; the core polymer comprises at least one associative monomer; at least one shell copolymer layer copolymer comprises at least one associative monomer; and/or the at least one shell copolymer layer that is at least partially cross-linked comprises greater than 3 mole % crosslinking agent. Aqueous compositions comprising the alkali-swellable rheology modifier include personal care formulations, healthcare formulations, agricultural formulations, paint formulations, coating formulations, laundry and fabric care formulations, household cleaning formulations, and industrial and institutional cleaning formulations.

Described herein is a new process for the preparation of polysuccinimide derivatives-based core-shell microcapsules. Also described are microcapsules, as well as perfuming compositions and consumer products including these microcapsules, in particular perfumed consumer products in the form of home care or personal care products.

The present invention provides an organic-inorganic composite particle that is excellent in the reflectivity of visible light and near infrared light, and has high light diffusing property and opacifying property, a method for producing the same, and use thereof. More specifically, the present invention relates to an organic-inorganic composite particle comprising an outer shell composed of a crosslinked polymer, and a cavity that is partitioned with the outer shell, wherein the composite particle contains, inside the cavity, a porous structure in which silica particles as a first inorganic particle are interconnected, and a second inorganic particle other than a silica particle, and has a volume average particle diameter of 0.5 to 100 μm, a method for producing the same, and use thereof.

Janus particles, including biodegradable, biocompatible, anisotropic, amphiphilic Janus nanocolloids, and their use in stabilizing emulsions and cleansing are described.

The invention relates to compositions comprising a keratin pigment material. The keratin pigment material comprises dyed keratin particles. Compositions comprising keratin pigment material such as inks, paints and cosmetic formulations have advantageous properties compared to similar compositions in which conventional pigment materials are used as colourants.

Described herein is UV-responsive ink capable of informing the user of UV exposure in real time, and a sun care kit incorporating the same.
