Detection Methods and Metrology Requirements of Peptides in Cosmetics

Peptide was applied to cosmetics more and more widely due to its good bioactivity. Types and functions of peptide in cosmetics were introduced. Most peptides have obvious effect of wrinkle removal, anti-aging, skin whitening and spot removing. Considering urgent requirement for detection method of peptide in cosmetics and metrology research, common peptide detection methods at present were summarized, including Kjeldahl determination, fluorescence detection, chemiluminescence detection, electrophoresis, colorimetry, enzyme-linked immunosorbent assay, chromatograph, etc.
