Cosmetic based on vegetable oils, such as sesame, peanut, sunflower and almonds, has beneficial properties to the human skin, and, for this reason, they are increasingly being used as moisturizers, emollients, regenerators and antioxidants, in bath oils, shampoos and hair conditioners, creams and lotions products. Nevertheless, these vegetable oils are made of high cost raw materials, and consequently they are targets of adulterations, especially with addition of soybean oil. Hence, people daily use in their body soybean oil, believing that they are taking care of their body health with other oils. This study evaluated the authenticity of Brazilian cosmetics based on vegetable oils with gas chromatography with flame ionization detection (GC-FID), and direct infusion by electrospray ionization mass spectrometry (ESI-MS). Details are presented in the Article Assessment of Adulteration of Cosmetics Based on Vegetable Oils by GC‑FID and Lipid Profile Using Direct Infusion Electrospray Ionization Mass Spectrometry (ESI-MS) by Jessica S. Pizzo, Marília B. Galuch, Patrícia D. S. Santos, Oscar O. Santos, Lorena Visentainer, Marcos N. Eberlin and Jesuí V. Visentainer on page 2457.
