Abstract:

In this study, the skin irritation and eye irritation of tea saponin were studied by using alternative models (including EpiskinTM reconstructed human epidermal model and chicken embryo chorioallantoic membrane test). The results show that 2%-10% tea saponin solution shows no skin irritation, and tea saponin solution less than 2% (mass fraction) does not exhibit eye irritation. Then, a shampoo containing 5.0% (mass fraction) tea saponin was prepared. By combined sensory evaluation, microscopic scalp observation and instrument test, the efficacy of tea saponin shampoo on scalp care was evaluated. The results show that the shampoo containing tea saponin shows good efficacy in removing dandruff, controlling sebum, relieving itching, lowering scalp sensitivity and improving barrier function. The above effects may be related to the biological activities of tea saponin, such as antibacterial, anti-inflammatory and anti-oxidation. This study can provide basic data for the safety and scalp care efficacy of tea saponin in shampoo.

Key words: tea saponin, shampoo, skin/eye irritation, scalp care efficacy
