  • Patent number: 5504231
    Abstract: The present invention relates to a process for preparing reduced calorie triglycerides which contain short or medium chain and long chain fatty acids, but which nevertheless contain low levels of difatty ketones. The process of the present invention comprises the step of adding glycerine to a crude reaction product after a selective esterification reaction of a monoglyceride with short or medium chain fatty acids fatty acids. The glycerin is typically added at a level of from about 0.1 to about 1.0% at a reaction temperature of from about 170.degree. C. to about 215.degree. C. The contact time is about 1 to about 15 minutes. The reduced calorie triglycerides prepared according to this process will contain less than about 100 ppm difatty ketones.

  • Patent number: 5496493
    Abstract: The present invention encompasses an ultra mild personal cleansing bar that contains small sized solid wax particles of which from 85% to 100% are less than 16 microns in size. Preferably 90% to 100% of the wax particles are from 0.1 to 15 microns in size, and more preferably they are from 0.1 to 10 microns in size. The smaller-sized solid wax particles of the present invention provide better mildness than comparable personal cleansing bars which contain larger wax particles. These smaller wax particles do not negatively impact bar in-use aesthetics, for example, bar lather.
