Herbal Extracts – Washing Agents for Coloured Fabrics?

Selection of saponins as natural detergents for washing of textiles contributes to the promotion of green chemistry in textile applications. Herbs such as European Ivy, wild chestnut, soapwort and soap nut shell are sources of saponins with specific hydrophilic and oleophilic character able to provide detergency properties. The objective of this research is to study the washing performance of saponins from European Ivy (Hedera helix) and soap nut shells (Sapindus mukorossi) in comparison to standard detergents and commercial products. The primary criterion is a colour preservation of pastel and dark shaded cotton and wool fabrics in washing at 40°C. The second criterion is UPF enhancement. Washing performance of applied agents was evaluated through optical and protective characteristics of fabrics based on colour difference and Ultraviolet Protection Factor (UPF). The results confirmed a multifunctional ability of saponins from herbal extracts for colour protection and enhanced UPF of washed cotton and wool fabrics.
