Lab researchers Innovare Biomarker, Faculty of Medical Sciences (FCM), Unicamp, created a new research platform that uses images in two and three dimensions associated with identifying statistical data, in seconds, all the chemical components present or not in formulating beauty products.

This new platform, called Cosmetômica, offers up to 99% accuracy, providing manufacturers and consumers with the quality and safety of products. To test the power of the application platform which for the first time in cosmetics area, an analytical technique combined with the statistical treatment of data, the researchers analyzed the major brands of nail polishes, lipsticks and eye pencils on sale in stores and Brazilian markets . This is the first work in which techniques were used Desorption Ionization Matrix Assisted Laser (the acronym MALDI) and Mass Spectrometry Imaging (MSI also of English) in the field of cosmetics.

Without revealing the brands analyzed, the researchers found that three of the nine enamel samples investigated presented in its composition high rates SUDAM III, a substance considered potentially carcinogenic, five samples of lipstick were analyzed (two new, two in use and one with term validity expired), and one of the products in use showed significant changes in some sensory characteristics such as rancid odor, even before the expiration of the validity period, while another brand was not one of moisturizing ingredients described on the label.

Three samples were analyzed eyeliner (one new, one used and one using expired). The product showed overcome substances, and irritations and allergies, can make the ocular environment conducive to proliferation of microorganisms that cause infections in the region.

The results were published in the March issue of revista Materials, Article Cosmetic analysis using Matrix-Assisted Laser Desorption / Ionization Mass Spectrometry Imaging (MALDI-MSI). The research was conducted by the pharmacist Noin Diogo de Oliveira, student graduate program in medical sciences FCM, UNICAMP.

I took the MALDI-MSI, used in the medical field for the display of animal tissues and plant and I associated it to the area of ​​production processes. Defined substances and biomarkers exist for each product tested, established mathematical data using specific software and gathered it all on this platform which I called Cosmetômica the study of all the processes and products which involve cosmetic, Diogo said.

According to Rodrigo Ramos Catharino, professor of Pharmacy at Unicamp and responsible for supervising the work, the application of this new platform allows you to follow the entire process of producing a cosmetic, from raw materials to their degradation or as they say in chemistry, the oxidation number of electrons that an atom or molecule loses or gains to acquire chemical stability. This generates a better use of the product for the company, as well as safety, health and quality of life for the consumer.

With this new platform, we analyze the product that is in the consumer's home and say that the substances contained therein do, really, what industries promise or not, complete Catharino.
