摘要:
The use of novel nonionic polymeric thickeners that produce cosmetically useful emulsions of an oil phase and a water phase is described. The thickeners of choice are the urethane dimers of ethoxylated fatty alcohols. These materials were not anticipated to have emulsifying properties. Also, it has been found that the esters of ethoxylated polyols show similar emulsifying behavior, although their uses are limited by their inherent susceptibility towards hydrolysis. Further, many of the emulsions produced with these emulsifiers have a dilatant or shear thickening rheology that is unusual and has unique cosmetic applications. In addition, it is possible to produce high internal phase oil-in-water emulsions, with oil phase concentrations greater than 70%, using these emulsifiers. Finally, many of the emulsions, especially the high internal phase ones, have a characteristic “ring” or vibration that is apparent when their container is tapped. This is a characteristic of so called “microemulsions” that has not been observed in conventional appearing, white (albeit dilatant) emulsions.

A novel flexible infrared device is provided for heating surfaces in a uniform manner not available previously. The heater is designed in a manner so as to allow “hugging” of the surface by attaching the heater module to at least two swivel points located above the heating plane. In this manner the common problems encountered with heating dies by IR heaters is overcome.

摘要:
A method and apparatus for modeling cellular structure is disclosed. The system incorporates a theoretical hypotheses of cellular physiology into a simulation framework that allows direct comparison of simulation results with experimental data. The description of the biological model is kept independent of the solution by the use of an integrated anatomical and physiological modeling language. This framework allows complex heterogeneous intracellular chemical simulations to be built with little or no knowledge of the underlying numerical methods. Because the simulation results are easily compared to the experimental results, the user can more easily confirm the hypothesis.

A bag includes a first panel with at least one access hole in it, and a second panel without a hole corresponding to the at least one hole of the first panel. Preferably, two holes are present, preferably near the bag mouth. The panels are substantially equal in length. The bag can be easily opened by described bag opening means, without the need for vacuum or air to open the bag. The bag can be used in conjuction with otherwise conventional taped bag systems. A metod of making the bag, a bag opening system, a method of opening the bag, and a packaging system are also disclosed.
摘要:
This invention relates to a method for forming hollow silica-based particles suitable for containing one or more active ingredients or for containing other smaller particles which may include one or more active ingredients. The method comprises preparing an emulsion including a continuous phase that is polar or non-polar and a dispersed phase comprising droplets including (i) a polar active ingredient when the continuous phase is non-polar or (ii) a non-polar active ingredient when the continuous phase is polar; and adding a silica precursor to the emulsion such that the silica precursor can be emulsion templated on the droplets to form hollow silica-based particles. The silica precursor has the general formula (I): R1x—Si—(OR2)y, wherein R1 is selected from substituted and unsubstituted alkyl, substituted and unsubstituted aryl, alcohols, amines, amides, aldehydes, acids, esters, and functional groups having an unsaturated carbon-carbon bond, R2 is an alkyl group, x+y=4, and y=1, 2 or 3. The —OR2 group is a hydrolyzable organic group that exhibits an ability to form a silicon-oxygen bond chain as a result of hydrolysis and condensation.
