title: Development and efficacy assessments of tea seed oil makeup remover.
abstract: BACKGROUND
  The efficacy of tea seed oil to clean foundation and eyeliner was evaluated. The safe and efficient tea seed oil makeup remover was developed.
  
  
  METHODS
  In vitro cleansing efficacy of makeup remover was UV-spectrophotometric validated. The stability evaluation by means of accelerated stability test was conducted. In vitro and in vivo cleansing efficacy of the removers was conducted in a comparison with benchmark majorly containing olive oil.
  
  
  RESULTS
  Tea seed oil cleaned 90.64±4.56% of foundation and 87.62±8.35% of eyeliner. The stable with most appropriate textures base was incorporated with tea seed oil. Three tea seed oil removers (50, 55 and 60%) were stabled. The 60% tea seed oil remover significantly removed foundation better than others (94.48±3.37%; P<0.001) and the benchmark (92.32±1.33%), but insignificant removed eyeliner (87.50±5.15%; P=0.059). Tea seed oil remover caused none of skin irritation as examined in 20 human volunteers. A single-blind, randomized control exhibited that the tea seed oil remover gained a better preference over the benchmark (75.42±8.10 and 70.00±7.78%; P=0.974).
  
  
  CONCLUSIONS
  The safe and efficient tea seed oil makeup removers had been developed. The consumers' choices towards the makeup remover containing the bio-oils are widen. In vitro cleansing efficacy during the course of makeup remover development using UV-spectrophotometric method feasible for pharmaceutic industries is encouraged.
