“…Gutiérrez-Hernández et al suggested that LNPs could be matched to the skin tone of the person using the sunscreen formulation. 114 Lignin has been combined with photoactive metal oxide nanoparticles to quench photocatalytic activity of titanium dioxide NPs [115][116][117] and to broaden the UV-blocking spectrum of zinc oxide NPs in sunscreen formulations. 114 The excellent ability of LNPs to stabilize emulsions is an additional advantage of their use in sunscreens.…”

Cellulose nanocrystals (CNCs) were isolated from Agave tequilana residues derived from ethanol production. Hemicelluloses and lignin extraction from agave bagasse was carried out via organosolv (ethanol/acetic) digestion followed by conventional sulfuric acid hydrolysis. The ethanol/acetic acid treatment resulted in cellulose yields of approximately 67% after lignin and ash removal. Compared to soda and sodium chlorite treatments with organosolv, the time and chemical load needed for delignification were remarkably reduced. The morphology of the cellulose fiber obtained in the three treatments was between 0.55 and 0.62 mm, with which CNC was obtained in the order of 83 to 195 nm in length. It is noteworthy that the longest cellulose fibers and nanocrystals were obtained from organosolv cellulose. The organosolv treatment led to a high purity cellulose, derived CNCs with a minimum energy consumption and mild chemical usage, and also considered the use of material streams associated with distillation processes. Thus, a viable alternative is suggested for the production of high quality CNC from widely available residual biomass that otherwise poses environmental and health-related risks.

“…Inorganic and organic filters are sunscreen active ingredients 11 , i.e., the compounds responsible to the UV photoprotection of the human skin. Among inorganic and organic commercial filters, zinc oxide, 1-(4methoxyphenyl)-3-(4-tertbutylphenyl)propane-1,3-dione and hexyl 2-(4-diethylamino-2hydroxybenzoyl)-benzoate have been widely used as broad spectrum filters in sunscreens due to their high UV shielding ability 6 .…”

Sunscreen formulations containing inorganic/organic filters or mixture of them were synthesized by oil/water dispersion. The viscosity measurements show that sunscreen formulations are time-dependent non-newtonian fluids. In the CIELab color diagram, the white and/or beige colors presented by formulations do not compromise the aesthetics of the cosmetic product. UV-VIS absorption spectra show that sunscreen creams have high UV shielding ability, mainly the formulations containing inorganic and organic filters mixtures, which provide in vitro SPF and critical wavelength values recommended for UV protection.
