769 results about "Stearyl alcohol" patented technology

Stearyl alcohol (also known as octadecyl alcohol or 1-octadecanol) is an organic compound classified as a fatty alcohol with the formula CH₃(CH₂)₁₆CH₂OH. It takes the form of white granules or flakes, which are insoluble in water. It has a wide range of uses as an ingredient in lubricants, resins, perfumes, and cosmetics. It is used as an emollient, emulsifier, and thickener in ointments, and is widely used as a hair coating in shampoos and hair conditioners. Stearyl heptanoate, the ester of stearyl alcohol and heptanoic acid (enanthic acid), is found in most cosmetic eyeliners. Stearyl alcohol has also found application as an evaporation suppressing monolayer when applied to the surface of water.

Multiparticulates

Extrusion of a mix containing a pharmaceutically active agent can be achieved using a plasticising excipient in an amount sufficient to act as plasticiser and also act as lubricant, thereby avoiding the need for inclusion of a lubricant. The invention provides multiparticulates with controlled release properties, substantially free of lubricant. The present invention is preferably directed to extruded multiparticulates containing an opioid such as oxycodone, an ammonium methacrylate copolymer such as Eudragit® RSPO, a plasticising excipient such as preferably stearyl alcohol and a water permeability modifier such as preferably Eudragit® RLPO. The obtained multiparticulates show a release rate profile which is pH-independent.

Modified pearl cherry vitamin C sleeping mask and preparation method thereof

The invention relates to a modified pearl cherry vitamin C sleeping mask. The preparation method of the sleeping mask comprises the following steps: heating nanometer pearl powder to activate, reacting with surfactant to prepare modified nanometer pearl powder, dispersing the modified pearl powder in aqueous phase through turbine stirring, dissolving sodium hyaluronate, glyceryl polyether and butanediol in water, fully stirring, heating, then adding the components of the formula such as Tween-20, isononyl isononanoate and cetearyl alcohol in a pan, stirring to homogenize, cooling to about 45 DEG C, and adding additives, essence, preservative and the like in turn to prepare the modified pearl cherry vitamin C sleeping mask. In the sleeping mask of the invention, the surfactant reacts with the surface hydroxyl groups of the nanometer pearl powder so that the affinity of pearl powder to organic medium is increased and the detects of the nanometer pearl powder that the specific area is large and the nanometer pearl powder is easy to agglomerate and is hydrophilic and oleophobic can be overcome; and cherry vitamin C and nutrient components with permeability and moisture retention capacity are also used, thus the moisture and nutrient components in the mask of the invention can completely permeate the skin during sleep and the state of the skin can be improved intensively.
