Abstract

Whitening cream is a combination of chemical compounds that are efficacious in reducing hyperpigmentation. The use of creams with a hydroquinone content of more than 2% for a long time can cause skin cancer. The purpose of this study was to determine the presence of hydroquinone content, how much hydroquinone content, and the effect of storage conditions for cream containing hydroquinone. Researchers used 5 samples of facial whitening cream taken from the Central Lombok Regency. FeCl3 reagent, Benedict's reagent, TLC method and UV-Vis spectrophotometric method were used for qualitative and quantitative analysis to determine the percentage of hydroquinone content in the sample with the influence of temperature. The results of the analysis showed the presence of hydroquinone in 3 samples of facial whitening cream. The percentage of concentration obtained in the treatment condition of the sample from three times of replication at room temperature of sample A was 3.2%; sample D by 1%; sample E of 3.5%. Samples in air-conditioned room temperature sample A of 3.5%; sample D by 3.7%; sample E is 4.4%, and sample at refrigerator temperature is sample A is 4%; sample D by 4.1%; sample E by 5%. Hydroquinone levels in cream with closed cream storage conditions in the refrigerator resulted in the highest percentage of levels compared to storage at room temperature and air-conditioned room temperature, it can be concluded that the storage area greatly affects the hydroquinone levels in facial whitening cream. Keywords : Face whitening cream, hydroquinone, UV vis spectrophotometry
