Green Tea Extract Study at the Islamia University of Bahawalpur Featured Hettich EBA 20
The international Journal of Academic Research published a study entitled “Applications of a stable green tea extract cream on human cheeks” conducted by researchers at the Islamia University of Bahawalpur. The study was conducted to determine a stable dermatological formulation for green tea (Camellia sinesis) extract, as well as to discover its effect on skin hydration and the skin’s transepidermal water loss (TEWL). Hettich’s EBA 20 tabletop centrifuge was the primary instrument used to isolate Camellia sinesis.
Camellia Sinesis is of the genus Camellia, which are flowering plants in the Theaceae family. Various types of tea (white tea and oolong, among others) are harvested from this species. Extracts derived from the tea plant have been found to contain health benefits including high levels of the antioxidant catechin. The presence of catechin makes the extract a popular ingredient for creams, ointments as well as other beauty and health products.
A single-blinded study with placebo control was designed for the comparison of two creams, the base formulation and the active formulation. The active formulation was labeled “A,” while the base formulation was labeled “B.” Normal-skinned volunteers aged 25 to 40 joined the 60-day study, during which they followed mandatory application instructions for the two formulations. Results were measured with suitable techniques in a controlled room at 21˚C ± 1 and 40˚C ± 2 % relative humidity. Centrifugation with the Hettich EBA 20 was a key step in this research because it enabled the scientists to determine the formulations' emulsion stability. For example, scientists were able to determine that “centrifugation at 15,400 g for a 5 hours period would be sufficient to state the emulsion stability for a period of one year.”
Researchers concluded that stable aesthetic formulation of green tea extract is possible upon combining ABIL® EM90 and paraffin oil with the ideal skin pH range. This study seeks to assist in developing new dermatological formulations for optimal skin maintenance.
Hettich centrifuges have been diversely applied to conduct valuable research, including this green tea extract study. The Hettich EBA 20 is a tabletop centrifuge ideally suited for many routine and specialized applications. Learn more about the Hettich EBA20 at http://www.hettweb.com/hettich-eba-20-centrifuge.html.
