Abstract:
A microparticle delivery system for an active compound which includes an active compound loaded onto polymeric microparticles, wherein the loaded microparticles are encased by a matrix material comprising about 68% to about 99%, by weight, of the microparticle delivery system. Compositions containing the microparticle delivery system, and methods of manufacturing the microparticle delivery system, also are disclosed.
Abstract:
A composition wherein phase or chemically incompatible components are introduced into a stick composition through the use of a microparticle delivery system, preferably a Poly-Pore ® polymeric microparticle system.
Abstract:
Compositions containing a delivery system including polymeric microparticles capable of undergoing a visual change, such as a color change, after application to a substrate are disclosed. The delivery system informs a consumer that the composition has been properly applied and/or has performed its intended function.
Abstract:
An organophilic clay for thickening hydrophobic liquids comprising a layered silicate material, surfaces of said layered silicate material modified by an amphipathic copolymer prepared from a first comonomer that generates a hydrophilic homopolymer that is essentially insoluble in a hydrophobic liquid and a second comonomer that generates a hydrophobic homopolymer that is soluble in a hydrophobic liquid, said organophilic clay containing at least 10% by weight water, based on the dry weight of the layered silicate material.
Abstract:
A composition and method for reducing the shine of human skin is disclosed. The composition imparts a topical matte finish to the skin for an extended time period. The composition contains polymeric microparticles, optionally loaded with a cosmetic or therapeutic skin care compound.
Abstract:
Cosmetic and personal care compositions can be manufactured using the multifunctional-additive compositions of the present invention. Such an additive preferably contains one or more particulate-based thickeners, such as a smectite clay, colloidal silica, laponite, and/or alumina, and most preferably one or more smectite clays. According to one important embodiment of the present invention, the thickener particles are co-dispersed with particles of one or more particulate UVR-filters such as titanium dioxide, zinc oxide, or SUNSPHERE (available from International Specialty Chemicals, ISP), and most preferably with the natural particulate sunscreens such as the metal oxides. Another important component of the multifunctional-additive compositions is a dispersant or surface-modifier for the foregoing particulate materials, selected from the family of polyphenolic, natural polymers such as lignosulfonates, lignins, humates, tannates, and derivatives thereof. In addition, these compositions optionally include one or more of the following components: electrolytes, defoamers, humectants, emollients for cosmetics, preservatives, whiteners, and the like.
Abstract:
A controlled release composition comprising an adsorbent polymer, an active agent, and a release retardant is disclosed. The composition has an improved ability to release the active agent over an extended time period.
