A New Protocol to Evaluate Superior-Resistant Attributes of Liquid Foundation for Javanese-Indonesian Brides

Presented by: Festy Devitama
Background:
A wedding is a very important event in Indonesian culture. As an ethnic majority, Javanese have a unique marriage custom including Siraman (a traditional shower ceremony), Sungkeman (a touching moment of asking blessings from parents), followed by a wedding reception attended by groups of people. Given this particular practice, in addition to the hot and humid climate that Indonesia has, the resistance properties of Javanese bridal foundation against water, tears, sebum and sweat become crucial in order to achieve the long lasting effect throughout the ceremony.
Multiple in-vitro and in-vivo methods have been utilized to evaluate the water-proof, tear-proof, smudge-proof, and sweat-proof attributes of foundation but no approach has been developed specifically to portray extreme circumstances like Javanese marriage ceremonies. This study proposes convenient and fast screening tests to assess foundation properties under water, tear, sebum, and sweat conditions, simulating the performance of foundation needed for Javanese-Indonesian brides.
Methods:
To achieve the water-proof, tear-proof, smudge-proof, and sweat-proof claims, four commercial foundations with different resistant properties were prepared. The in-vitro test was performed by immersing each foundation film on PMMA plates into four different liquids (artificial sebum, sweat, tear, and water) for 8 hours and the film conditions were evaluated afterwards. A related in-vivo study was carried out in 3 female volunteers with different treatment for each claim. Smudge-proof test was conducted on subjects with oily skin for an 8 hours application. Standardized cardio exercise was performed to induce sweat production representing the hot condition during the ceremony. Emotional condition was set by watching a sad movie to portray the touching moment of Sungkeman. To reflect the Siraman ceremony, tap water was poured on to the head ensuring the water was flown on the face. The condition of foundation before and after the treatment was observed and photographed using a digital camera and analyzed using image analysis.

Results:
The four foundations showed different results in all tested attributes, proving that these methods are reliable to evaluate superior characters of foundations. Positive correlation between in-vitro and in-vivo test results was observed, thus providing a new fast approach in predicting the superior-resistant attributes required when formulating the perfect foundation for Javanese-Indonesian brides.
Discussion and Conclusion:
Through this study, we were able to understand our consumer’s needs especially for Indonesian brides who choose Javanese tradition for their wedding ceremony, thus we can deliver the right solution for them. These methods can help the formulators to develop the desired foundation products in parallel with the product’s efficacy and increase the satisfaction of the consumers.
