Abstract From the Canadian patent

Oleaginous substances such as vegetable oil baby, oil, olive oil, margarine, lanolin cocoa butter and the like, have their affinity for water altered by mixing the oleaginous substance with sugar and melt spinning the mixture in a cotton candy spinning machine or the equivalent. As so modified the product disperses autogenously in water forming a colloidal or colloidal-like dispersion. The modification enables such widely disparate procedures as incorporating shortening oil in a cake mix containing flour but no egg producing a confection, or medicated lozenge by dehydrating the dispersion and allowing the melted residue to solidify.

Why it's free to use

  • Filed December 12, 1989 and granted September 7, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 12, 2009.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 12, 2011.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
