Symrise Research, Hamburg, Germany, conducted antioxidant efficacy tests of Neo-Extrapone organic rooibos and Neo-Extrapone organic green tea and concluded that both are equally effective antioxidants. Both ingredients belong to the Symrise range of organically certified botanical extracts. The products are concentrated, preservative-free powders with no solvents. The antioxidant capacity was evaluated by using three different in-vitro methods: the DPPH and ABTS assays, which are two chemically-based radical scavenging tests and the DHR assay, a cellular test using 3T3 fibroblasts. Both products showed considerable antioxidant capacities in all three assays, according to company executives.
The results establish that rooibos, like green tea, is a useful extract with protective properties for use in cosmetic products. More info: E-mail: email@example.com.
