Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water. The hydrophobic phase can be semisolid petrolatum.

An emulsion composition and a method for preparing the emulsion composition are disclosed. The emulsion composition contains an inner phase; an external phase; and a plurality of interfacial particles surrounding the surface of the inner phase to form an interface, wherein the interfacial particles have a particle size smaller than the inner phase, and the interfacial particles include organic particles. The method for preparing the emulsion composition includes steps of: preparing a colloidal solution comprising a dispersion medium and organic particles dispersed in the dispersion medium; preparing an aqueous phase; preparing an oil phase; and mixing the colloidal solution, the aqueous phase, and the oil phase so as to prepare the emulsion composition.

The present invention relates to an emulsion not containing any emulsifying surfactant, in particular to an oil-in-water emulsion not containing any emulsifying surfactant, characterized in that it comprises, especially in a physiologically acceptable medium, at least composite particles comprising a core comprising at least organic or inorganic particles A; said core being covered at the surface, continuously or discontinuously, with an envelope comprising at least organic or inorganic particles B; said particles A and B having different polarities.

According to the present disclosure, a method of preparing polymeric microparticles comprising further crosslinking with an organic crosslinking agent after crosslinking with metal ions, polymeric microparticles, medical compositions, cosmetic compositions, medical articles and cosmetic articles comprising the same can be provided.

The present invention provides a method and kit for the treatment of surfaces, such as the skin surface of a user, to impart hydrophobic characteristics upon the surface. The treatment of surfaces to impart hydrophobicity protects equipment, personnel, and animals from the effects of aqueous solutions such as water, toxic slurries, concrete, acids and bases.

The present invention relates to an emulsion not containing any emulsifying surfactant, in particular to an oil-in-water emulsion not containing any emulsifying surfactant, characterized in that it comprises, especially in a physiologically acceptable medium, at least composite particles comprising a core comprising at least organic or inorganic particles A; said core being covered at the surface, continuously or discontinuously, with an envelope comprising at least organic or inorganic particles B; said particles A and B having different polarities.

The present invention also relates to the use of the composite particles as defined previously as emulsion stabilizer, in particular as stabilizer for an emulsion not containing any emulsifying surfactant, and more particularly as stabilizer for an oil-in-water emulsion not containing any emulsifying surfactant.

The present invention also relates to a cosmetic process for treating a keratin material, which consists in applying to the keratin material an emulsion as defined previously.

The present disclosure relates to an anhydrous composition, and the composition according to one aspect of the present disclosure includes: a fatty alcohol; an emollient; a wax; and a poorly soluble substance, and has a viscosity of 300 cSt or more at 30 C., and can stabilize poorly soluble substances that provide effects to the human body to increase the moisture retention in the skin or hair, and can simultaneously provide softness and shine to the hair upon use, and exhibit excellent feeling of use without stickiness or residual feeling on the hands.
