Green Tea Oil:  The health benefits of green tea are primarily due to its antioxidant properties that come from its caffeine.  Another powerful benefit of green tea is that it boosts the strength of the immune system. The astringent substances in green tea trigger contractions in muscles and tissues, while toning up muscles and skin.
Soy emulsifier:  When it comes to creating a cream or a soap, something must be done to water and oil based ingredients in order for them to combine.  Emulsion occurs when water is allowed to encapsulate oil molecules with the help of a stretchy ingredient called an emulsifier.  Lecithin is a common emulsifier found in nature.
