The Influence of Packaging on Cosmetic Emulsion during Storage Assessed by FT-NIR Spectroscopy and Color Measurements

J Cosmet Sci. 2018 Jul/Aug;69(4):245-255.

Abstract

FT-NIR spectroscopy and color measurements were applied to evaluate the influence of packaging on cosmetic cream stored at room and refrigerated conditions. Commercial cosmetic cream was stored for 2 and 4 mo in five containers intended for cosmetics: aluminum jar with polypropylene thermos (Al/PP), acrylic jar with polypropylene thermos (Ac/PP), glass (G) jar, polypropylene (PP) jar, and styrene acrylonitrile (SAN) jars. Principal component analysis (PCA) of the FT-NIR spectra showed the effect of time on tested samples stored in all applied packagings; separate groups were formed by fresh samples and samples stored for 2 and 4 mo. The changes in samples stored in the cold for 2 mo were similar for all applied packagings as compared with fresh samples, although samples stored in SAN jars formed a separate group. After 4 mo, a separate group was formed by samples stored in G jars. For samples stored at room temperature, the influence of packaging material on cosmetic emulsion was clearly visible; four separate groups (Al/PP with PP, Ac/PP, G, and SAN) were created by samples stored for 4 mo. Using partial least squares (PLS1) regression, it was found that the FT-NIR spectra of tested samples correlated with their lightness L*, a* parameter, and total color difference ΔE * ab . FT-NIR spectroscopy is a rapid technique which could be useful to make the best choice of packaging for cosmetics protecting the original quality of products during long-term storage.
