Open the CIPO recordAbstract From the Canadian patent
Emulsified powders are prepared by emulsifying an oil-soluble substance, a chemically modified starch and if, desired, a vegetable gum in water. The emulsified powders obtained according to this process show less disintegration of emulsified particles caused by compressing impact which, leads to less oil exudation. The tableted product of the emulsified powders of the oil-soluble substance is easy in handling, weighing, ingesting and others and thus can be utilized over a wide range of technical fields such as foods and drinks, medicaments or the like.

Why it's free to use
- Filed October 7, 1998 and granted December 31, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 7, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 7, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
