This paper presents the use of inductively coupled plasma MS (ICP-MS) for direct elemental analysis in oleochemicals (long-chain fatty acid derivative). It focuses on Ca, P, and Fe, which are key elements for many industrial applications and which ar

Transmission (400 to 2500 nm) and reflectance spectra (400 to 2200 nm) were recorded from polyethylene films (low-density PE, cryst. 60%, additive free), with a thickness ranging from 0.2 to 8.46 mm. The information depth, defined as the thickness of

The hydroxyl value is an indicator for the stages of esterification reaction. Instead of the wet chemistry titration method, the near-infrared (NIR) spectroscopic technique was utilized to monitor the hydroxyl values during the reaction. Because of t

Maintenance of the right water levels in the skin is of crucial importance to maintain healthy, young-looking skin. Moisturizing products have therefore aimed to influence the constitutive levels of natural moisturizer factor (NMF) and/or the formati

A non-invasive ATR-FTIR technique has been used to directly measure skin conditions in vivo. From outside to inside, stratum corneum (SC) consists of fatty layer, one cell layer, a thick layer of lipid and another 10-20 layers of cells. Previous publ
