New Silicone Technologies for Skin Care

16-11-2009

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...

Bearing grease selection

03-09-2009

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...

Polyether-Modified Silicones for Cosmetic Applications

20-07-2009

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...
