“…Titanium oxide has been widely used as a cosmetic pigment and physical UV-filter for more than 40 years [1]. However, some titanium oxide samples, as well as related materials, exhibit photocatalytic activity that leads to reactive oxygen species (ROS) formation [2][3][4][5].…”

Titanium phosphates were recently revealed as promising cosmetic pigments; however, their photocatalytic activity and sun protective factor (SPF) levels have not been investigated in detail. In this study, we used hydrothermal conditions to prepare nanocrystalline anatase, brookite, and layered titanium phosphate using the titanium lactate complex, NH4H2PO4, and urea as precursors. The samples were characterized by powder X-ray diffraction (XRD) in addition to Raman spectroscopy, transmission and scanning electron microscopy (TEM, SEM), energy-dispersive X-ray spectroscopy (EDX), and UV-Vis spectroscopy. Furthermore, the photocatalytic activity, sun protective factor, and moisture retention ability were determined for the samples. Brookite exhibited the highest SPF value and anatase the lowest, while Ti2O2H(PO4)[(NH4)2PO4]2 displayed highly promising UV protection and moisture retention properties and, therefore, represents a polyfunctional pigment that is particularly well suited for cosmetic applications.

Sunscreens reduce the occurrence risk of skin disorders such as sunburn, skin aging, and cancer through their ability to absorb, reflect, and scatter ultraviolet (UV) radiation. This review provides an overview of UV filters as active ingredients of sunscreen products, emphasizing their classification and structural characteristics. Their photostability, mechanism of action of ultraviolet radiation absorption, optical properties, and regulatory status are discussed based on their chemical structure. The main classes of organic UV filters presented include aminobenzoic acid derivatives, salicylic acid derivatives, cinnamic acid derivatives, benzophenones, dibenzoylmethane derivatives, benzylidene camphor derivatives, triazines, benzimidazole derivatives, and benzotriazole derivatives. The pursuit of new UV filters through research is crucial in advancing sunscreen technology and ensuring the availability of effective and safe options for sun protection.

New 2-benzylidenethiobarbituric acid-(benzyloxyphenyl) derivatives were designed, synthesized, and evaluated as tyrosinase inhibitors. The products can be divided into two groups: 4-hydroxybenzaldehyde derivatives and vanillin derivatives. Some of the 4-hydroxybenzaldehyde derivatives showed significant inhibitory activity while all vanillin derivatives have no inhibitory activities. It seems that the presence of the methoxy group on the internal aromatic ring prevents the ligand-enzyme interaction. According to the tyrosinase inhibitory assay, 5-(4-([4-Methylbenzyl]oxy)benzylidene)-2-thioxodihydropyrimidine-4,6(1H,5H)dione (4g) is the most potent antityrosinase agents with an IC 50 value of 23.90 ± 0.08 μM. It showed even better inhibitory activity than kojic acid. The results of kinetic and molecular docking studies demonstrated that compound 4g acts as a noncompetitive inhibitor and can bind to some amino acids such as His263 and Val283 of the active site through Pi-alkyl and Pi-Pi interactions and areas around the active site via the hydrogen bond. In-silico adsorption, distribution, metabolism, excretion, and toxicity (ADMET) studies predicted that these products have good drug-likeness. All findings indicate the 2-benzylidenethiobarbituric acids with the benzyloxyphenyl tail have good potential for the treatment of melanogenesis compared to kojic acid.
