| 20120015014 | COMPOSITION EXHIBITING ENHANCED FORMULATION STABILITY AND DELIVERY OF TOPICAL ACTIVE INGREDIENTS - A therapeutic, cosmetic or cosmeceutic composition for topical application, capable of stabilizing an active ingredient and delivering the active ingredient, comprising a plurality of microcapsules having a core-shell structure. The microcapsules have a diameter of approximately 0.1 to 100 micron. The core of each microcapsule includes at least one active ingredient, and is encapsulated within a microcapsular shell. The shell is comprised of at least one inorganic polymer obtained by a sol-gel process, and the shell protects the active ingredient before topical application and is designed to release the active ingredient from the microcapsules following application. The composition is useful in encapsulating active ingredients, such as benzoyl peroxide, that are unstable in other formulation, or are irritating to the skin. | 01-19-2012 |
| 20110262506 | TOPICAL COMPOSITIONS CONTAINING COATED ACTIVE AGENTS - Provided is a multi component topical system including at least one component including at least one first active agent coated by metal oxide; and at least one skin treating component free of the active agent. Further provided are methods of using the multi component topical system and kits including them. | 10-27-2011 |

| 20100047357 | COMPOSITIONS FOR TOPICAL APPLICATION COMPRISING A PEROXIDE AND RETINOID - The invention relates to a composition for topical application comprising as an active ingredient a peroxide and a retinoid wherein one of said peroxide and retinoid is in the form of first microparticles comprising a solid particulate matter of the active ingredient coated by a metal oxide layer and the other of said peroxide and retinoid is present in an uncoated free form or in a coated form of the active ingredient. The invention further relates to method for treating a surface condition in a subject using said composition, a method for preparing a composition exhibiting improved stability, and a kit comprising: (a) a first composition comprising a peroxide as a first active ingredient; and (b) a second composition comprising a retinoid as a second active ingredient; at least one of said first and said second active ingredient being coated by a metal oxide layer. | 02-25-2010 |
| 20100016443 | METHOD FOR PREPARING PARTICLES COMPRISING METAL OXIDE COATING AND PARTICLES WITH METAL OXIDE COATING - The invention relates to a process for coating a solid, water-insoluble particulate matter, with a metal oxide comprising: (a) contacting the solid, water-insoluble particulate matter with an ionic additive and an aqueous medium to obtain a dispersion of said particulate matter having positive charges on its surface; (b) subjecting the particulate matter to a coating procedure comprising precipitating a metal oxide salt onto the surface of the particulate matter to form a metal oxide layer thereon to thereby obtain particulate matter coated by a metal oxide coating layer; (c) repeating step (b) at least 4 more times; and (d) aging said coating layer. The invention further relates to particles comprising a particulate matter coated by a metal oxide layer, to a use of the particles for topical administration, and to a method for preventing, reducing, or eliminating pests at a locus, using the particles. | 01-21-2010 |
| 20090081262 | METAL OXIDE COATING OF WATER INSOLUBLE INGREDIENTS - The invention relates to process for coating a solid, water-insoluble particulate matter, with a metal oxide comprising: (a) contacting the solid water-insoluble particulate matter with a cationic additive in an aqueous medium to obtain a dispersion of said particulate matter having a positive zeta potential; (b) coating the solid water-insoluble particulate matter by precipitation of a metal oxide salt onto the surface of the particulate matter, forming a metal oxide layer thereon; and (c) aging said coating layer The invention further relates to coated particulate matter obtained by the process and to compositions comprising solid, water-insoluble particulate matter, coated by a metal oxide layer, the particulate matter being a dermatological active agent or a pesticide. The invention additionally relates to methods of treating a surface condition in a subject using compositions comprising solid, water insoluble dermatologically active agent, coated by a metal oxide layer. | 03-26-2009 |
| 20080254082 | Methods for Crop Protection - The invention relates to a method for crop protection comprising administering to one or both of the crop and its environment a composition comprising a carrier; and microcapsules having a core material comprising a pesticide encapsulated by a silica shell, wherein the silica shell constitutes up to 10% w/w out of the total weight of the microcapsules, and wherein said administration gives rise to pesticide activity with immediate onset and prolonged effect. The invention further relates to a method for acute treatment of a pest-infested crop. | 10-16-2008 |
