The present invention teaches a foamable pharmaceutical carrier comprising a benefit agent, selected from the group consisting of a dicarboxylic acid and a dicarboxylic acid ester; a stabilizer selected from the group consisting of at least one surface-active agent; at least one polymeric agent and mixtures thereof; a solvent selected from the group consisting of water, a hydrophilic solvent, a hydrophobic solvent, a potent solvent, a polar solvent, a silicone, an emollient, and mixtures thereof, wherein the benefit agent, stabilizer and solvent are selected to provide a composition that is substantially resistant to aging and to phase separation and or can substantially stabilize other active ingredients. The invention further relates to a foamable composition further containing a liquefied hydrocarbon gas propellant.

Described herein is the method of using a complex coacervate system including Gum Arabic and chitosan as lubricating agents. Also described herein are consumer products including the complex coacervate system.

Described herein are dentifrices comprising stannous ions, fluoride ions, non-crustacean derived chitosan, and an abrasive system. Methods of making and using these dentifrices are also described.

The present invention relates to an adhesive patch. The adhesive patch includes a plurality of reliefs, each relief having a flat top face, and each micro channel groove defined between adjacent reliefs of the plurality of reliefs, wherein the plurality of reliefs and the micro channel groove are respectively formed on and defined the adhesive patch, and wherein a hydrogel layer is disposed on at least a portion of a bottom face of the micro channel groove and is contained in the groove. Therefore, the adhesive patch is well-adhered to a dry or wet adhered face.

Provided is a treatment composition for dyeing. The treatment composition for dyeing contains isophorone dimaleate or cystamine dimaleate as an active ingredient. The treatment composition for dyeing contains diamine dimaleate, in particular, isophorone dimaleate or cystamine dimaleate, thereby more effectively covering gray hair, preventing color loss and preventing damage to hair due to dyeing than conventional dyes.

The present invention concerns the use of a dry film having a water activity of less than 0.6, for a non-therapeutic cosmetic topical treatment of the skin, which dry film comprises at least one polymer of natural origin, at least one mineral filler, at least one plasticizer and at least one surfactant. The dry film has a moisturizing and anti-sebum effect when applied to the skin. The invention also concerns a method of non-therapeutic cosmetic treatment of the skin.

The present invention relates to a porous material having a scaffold comprising: one or more fibroin moieties A and one or more polysaccharide moieties B, wherein A and B are directly conjugated with another without an interconnecting linker structure. Moreover, the present invention refers to a method for preparing a porous material. The present invention further relates to an injectable composition comprising a particulate porous material according to the invention and to cosmetic and therapeutic uses thereof such as facial and body re-shaping as well as regenerating tissue.

A medical device or solution for treating dental discomfort by at least partially occluding dental tubules is disclosed. The medical device or solution contains a polysaccharide or other biocompatible polymer with an antimicrobial metal, antimicrobial metal compound, or antimicrobial metal ion bound to a biopolymer. The medical device or solution further comprises at least one soluble antimicrobial. The soluble antimicrobial may be a water soluble metal iodide, water soluble metal fluoride, or a water soluble metal chloride encompassed with the nanogel. The medical device may be a solution of a chitosan with a nanoparticle of silver fluoride on the chitosan and at least one of a sodium fluoride or silver fluoride. The solution may be water based solution. Methods of applying the medical device or solution are also disclosed.

Nanomaterials are an important class of materials for sunscreens. Conventional metal oxide nanoparticles are toxic in nature and leave white patches on skin after application. This disclosure provides a sunscreen composition containing biodegradable antimicrobial polymer nanoparticles as UV filter. The sunscreen composition comprising chitosan nanoparticles, at least one flavoring agent, at least one coloring agent, at least one stabilizer, and at least one preservative, in a defined form, wherein size of the chitosan nanoparticles is ranging from 200 to 900 nm. The size of the chitosan nanoparticles ranging from 200 to 400 nm for air medium, 500 to 700 nm for water medium and 700 to 900 nm for ethanol medium. The chitosan polymer is derived from chitin, a glucosamine polymer. The sunscreen composition is available in the defined form selected from a group consisting of a skin cream, a skin lotion, a powder, a gel, and a sprayable liquid.

Described herein are a new process for the preparation of microcapsules, and microcapsules obtainable by this process. Perfuming compositions and consumer products including the microcapsules, in particular perfumed consumer products in the form of home care or personal care products, are also described.
