**5. Conclusions**

Herbal saponins, tea, were studied to find alternatives to synthetic surfactants that are commonly used and were make comparison with marketed available surfactant (Surf Excel). The outcomes demonstrated that saponins are naturally acidic and decomposable. Natural materials are considered to be biodegradable as plant extracts. The tea, which was probably examined by the first time, shows good effectiveness, in addition to high foaming capacity, decent cleaning capacity and ultra-soft. Although lots of works account on isolation, characterization, etc. Tea has good emulsifiers and can find some industrial uses. We also quantified the cleaning capacity of surfactant solutions. Therefore, our studies can offer a simple and inexpensive method to measure the general cleaning method for the evaluation of detergents. We conclude that tea comes with good surface-active properties. These studies can offer useful information for the food industry as well as the cosmetics industry reason was that these plant-based materials were biodegradable organic surfactant. We propose new biodegradable and renewable alternative from plant-based material which act as a surfactant.
