The surface of human hair (hair) is covered with a lipid called 18-methyl eicosanoic acid (18-MEA). The surface of animal fur (coat) is believed to contain various lipids secreted from sebaceous glands, not limited to 18-MEA. Additionally, a decrease in linoleic acid has been reported in the sebum of animals with skin diseases. Therefore, simultaneously analyzing the representative lipid 18-MEA along with several other components is useful for understanding the condition of the hair. This document presents the results of evaluating the differences in lipids for each type of animal (pet) using TOF-SIMS.
