摘要:
A water-soluble substrate, and more particularly a water-soluble substrate that is resistant to contact with small amounts of water, and methods of making the same are disclosed. A coating which is less water-soluble than the water-soluble substrate and in the form of particles, is applied to and substantially covers at least one surface of the water-soluble substrate. The weight ratio of coating to water-soluble substrate is higher than 0.8. Articles, such as pouches, made from the water-soluble substrate, are also disclosed herein.
摘要:
A static mixer having one or more stages and/or elements. The static mixer may be scaled from bench size to any commercially desired size. During scale-up the surface area to void volume ratio is maintained constant. Maintaining this ratio constant may be accomplished by increasing the number of bars in each element of the static mixer.
摘要:
A method of making high internal phase emulsions is described. The method forms high internal phase emulsion (HIPE) using a single pass through the static mixer. In alternative embodiments, the HIPE may be further processed to farther modify the size of dispersed phase droplets, to incorporate additional materials into the HIPE, to alter emulsion temperature, and the like.
