• New Silicone Technologies for Skin Care
  

  In today's competitive skin care market, consumers look for a range of benefits, superior aesthetics and cost effectiveness. In response, formulators strive to create products that are multifunctional, easy to use and effective in small quantities. At the same time, the most successful products deliver benefits that stand out from those of the competition. Creams, lotions and color cosmetics must be easy to spread and comfortable to wear, without feeling tacky or greasy. Silicones have been popular ingredients in skin care products for more than fifty years. These versatile materials are known for their emolliency, wetting and spreading characteristics and ability to provide unique aesthetics. As technology continues to evolve, silicones increasingly offer multifunctional, high performance properties. This article reviews some of the newest silicone technologies available for the formulation of innovative skin care products more

• Bearing grease selection

  Rolling-element bearings are used for the precise guidance of moving parts. Frictional losses are extremely small because the bearings rest on rolling elements, enabling very heavy loads to be adsorbed. Rolling-element bearings may be lubricated with greases or oils depending on the point of use. Lubrication is necessary to prevent direct metallic contact between rolling elements and bearing rings, thereby preventing wear due to welding, friction, material fatigue or corrosion more

• Polyether-Modified Silicones for Cosmetic Applications
  

  Polyether-modified silicones have a long history of use in the personal care industry as emulsifiers and dispersants, as well as stabilizers for water-in-oil systems. However, because of their external phase type, water-in-oil systems tend to display poor aesthetics, such as greasiness, tackiness and slow absorption. A new polyether-modified silicone, PEG/PPG-19/19 dimethicone (and) C13-16 isoparaffin (and) C10-13 isoparaffin, was evaluated for its potential to aid in the production of stable water-in-silicone and water-in-oil formulations with unique textures and enhanced aesthetics. Various oil phases were studied, including silicone oils, organic oils, and a combination of both. Results of the evaluations demonstrate the versatility of the new material, and prototype formulations illustrate its broad utility more

• NHC-Mediated Cross-Coupling of Sugar-Derived Cyclic Nitrones with Enals: General and Efficient Synthesis of Polyhydroxylated Pyrrolizidines and Indolizidines

  A general and efficient method for the synthesis of polyhydroxylated pyrrolizidines and indolizidines has been developed based on the NHC-catalyzed cross-coupling of sugar-derived cyclic nitrones with enals, which afforded the key intermediates, γ-hydroxyl amino esters, in good to excellent yields. more

• Catalytic Asymmetric Five‐Component Tandem Reaction: Diastereo‐ and Enantioselective Synthesis of Densely Functionalized Tetrahydropyridines with Biological Importance

  Abstract The first catalytic asymmetric five‐component tandem reactions of β‐keto esters, aromatic aldehydes and anilines have been established in the presence of a chiral phosphoric acid, affording densely functionalized tetrahydropyridines with concomitant generation of five σ bonds and two st more

• Model Studies of the Kinetics of Ester Hydrolysis under Stretching Force

  Experiments and computations are reported of how stretching a polymer containing an ester moiety affects the kinetics of its basic hydrolysis (see picture). DFT computations of complete conformational ensembles of three homologous esters suggest that a stretching force stabilizes the tetrahedral more
