According to the Food and Drug Supervisory Agency of Indonesian Republic, 2011: HK.03.1.23.08.11.07517, in which the preservative levels of nipagin (methyl paraben) in a body lotion must be 0.4%, Preservative level over 0.4% may result in skin irritation and allergic reactions.

Nipagin’s identification was carried out with a qualitative analysis using Thin Layer Chromatography and color change using 2% of deniges reactor and sodium nitrite, while the quantitative analysis was carried out with spectrophotometry UV-Vis at 258 nm wavelength that was previously extracted with 96% of ethanol solvent. The results of the qualitative study show that four (A, D, E, and F) out of six samples of body lotions: A, B, C, D, E, and F contained preservatives. Quantitatively, the levels of nipagin) on the four samples are sequentially shown as follows: by A:0.38%, D:0.04%, E:0.14%, F:0.14%.
