The science of Liposomal Encapsulation dates back to the late 1970’s and early 1980’s. The process was initially created and used by pharmaceutical companies as a method to deliver drugs to specific organs or locations in the body without gastric juices acting on them and compromising the integrity, strength or structure of the drug. It was also important that the entire drug dose be absorbed into the bloodstream through the small intestine with little or none of it reaching the bowel. As time passed, much broader and more practical uses for this technology were developed including topical applications for medicines and cosmetics.
The secret to the successful use of Liposomal Delivery comes from producing a liposome-encapsulated molecule so small that it is absorbed almost immediately. This is easier said than done. Every different substance subjected to liposomal encapsulation presents its own set of challenges and you have to select the right combination of phospholipids and other ingredients to perfect the formula.
