Described herein are oral care compositions comprising metal silicates (e.g. potassium silicate); along with methods of making and using same.

The present invention relates to a composition for the protection against solar radiation, consisting of an organic matrix, preferably a gelatin, and hydroxyapatite nanoparticles modified by the substitution of part of the phosphorus with titanium, and part of the calcium with iron.

The present technology generally relates to an encapsulation system for delivery of an active agent, the encapsulation system comprising a matrix of microcapsules, wherein a first portion of microcapsules in the matrix of microcapsules has an average diameter of from about 0.1 microns to about 10 microns; a second portion of the microcapsules has an average diameter of from about 10 microns to about 100 microns; and a third portion of the microcapsules has an average diameter of from about 100 microns to about 500 microns; and wherein the active agent is encapsulated in the microcapsules.

The present disclosure relates to delivery systems. More particularly, the present disclosure relates to a process for releasing an active ingredient including a step of contacting a powdered composition with a medium having a pH7. The powdered composition includes granules made of a water soluble polymer matrix, an oil phase dispersed in said matrix and carbonate particles. Consumer products such as an antiperspirant or deodorant composition or a powder soft drink beverage composition including the powdered composition are also object of the present disclosure.

Delivery of compositions for treatment of skin tissue with photoactive plasmonic nanoparticles and light, with embodiments relating to delivery devices. Treatments are useful for cosmetic, diagnostic and therapeutic applications.

Disclosed are UV-protective compositions comprising swelled polymer matrix macroparticles comprising a thermoplastic polymer swelled with at least one swelling agent, and a plurality of nanoparticles of an inorganic UV-protective agent comprising at least one solid inorganic crystal and a dispersant associated with the crystal, wherein the inorganic nanoparticles are dispersed and embedded in the swelled polymer matrix macroparticles. Method of preparation and uses of such compositions are also provided.

This disclosure provides a hyaluronic acid (HA) bead, a dermal filler having hyaluronic acid (HA) and a process for preparing the HA beads. The process includes combining an HA compound with sodium hydroxide, forming an HA solution, and injecting the HA solution into an oil solution, and forming an emulsion with HA beads. A cross-linking reagent is added and the mixture is stirred for 24 hours in room temperature, thereby forming cross-linked HA beads. The HA beads are cross-linked and adapted to dissolve in vivo upon contact with hyaluronidase.

Disclosed are UV-protective compositions comprising swelled polymer matrix macroparticles comprising a thermoplastic polymer swelled with at least one swelling agent, and a plurality of nanoparticles of an inorganic UV-protective agent comprising at least one solid inorganic crystal and a dispersant associated with the crystal, wherein the inorganic nanoparticles are dispersed and embedded in the swelled polymer matrix macroparticles. Method of preparation and uses of such compositions are also provided.

Matrix particles containing one or more matrix materials and one or more hydrophobic active agents, agglomerated particles made therefrom, fibrous structures containing such matrix particles and/or agglomerated particles, and processes for making same are provided.

Disclosed is a preparation for the interdental delivery of oral care agent. The preparation comprising one or more oral care agents contained in particles comprising an orally acceptable release matrix, wherein the particles are resiliently deformable and capable of being compressed so as to fit in an interdental space. The particles can thus be provided in a size slightly larger than that of an interdental space. By compression they can be inserted, particularly jetted, into interdental spaces, and their tendency to thereupon expand again provides a force retaining them in the space where they were applied, without being prone to washing away by saliva.
