August 2016 in “International Journal of Cosmetic Science” In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.
July 2026 in “Pharmaciana” This study found that the optimal characteristics for ulin seed oil extraction are fresh, mature, and resinous seeds, and that FTIR spectrophotometry with PCA can effectively detect adulteration of the oil, particularly at certain wavenumbers like 1745 cm⁻¹.

February 2018 in “Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy” This study successfully used ATR FT-IR spectroscopy to uniquely identify or differentiate human hairs by detecting specific spectral features associated with individual hair characteristics and cosmetic residues on hair surfaces.
