Beyond Total Content: Assessing the Bioaccessibility of Metals in Tattoo Inks Using Validated Extraction Media

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT A validated analytical workflow is presented for determining total and bioaccessible concentrations of regulated elements in tattoo inks, addressing the lack of harmonized protocols for comparing extraction approaches in complex matrices. Although current legislation defines limits for soluble fractions of selected metals, it does not specify ...

Production of Bixin‐Rich Extracts From Annatto Seeds via Ethanol–Water Extraction Integrated With Ultrafiltration Technology

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Ethanol–water extraction followed by 5 kDa ultrafiltration yields a bixin‐rich annatto extract with 97.9% bixin rejection, 94.2% recovery in the retentate, and an enrichment factor of 1.29. Fouling analysis indicates an important contribution from cake formation, highlighting the role of membrane–solute interactions in the selective concentration of ...

Ethnobotany, Cytotoxicity and Color Stability of Karen Natural Colorants

Plants
Historically, natural pigments have been used to color textiles, food, and cosmetics, but the rise of synthetic dyes in the 19th century reduced their use. Recently, interest in plant-based pigments has surged due to health and environmental concerns. Among Thailand’s ethnic groups, the Karen use plant colorants extensively, but their practices remain ...

Cellular Responses to Tartrazine and Sulfanilic Acid Exposure in BEAS‐2B Cells: Viability, Apoptosis, and DNA Damage

Journal of Applied Toxicology, Volume 46, Issue 10, Page 3446-3454, October 2026.
ABSTRACT Tartrazine is a synthetic azo dye widely used in food, pharmaceutical, and cosmetic products, resulting in extensive human exposure, while its toxicity and that of its primary metabolite, sulfanilic acid, remain controversial. Considering the reported association of tartrazine with hypersensitivity and allergic‐like reactions, human bronchial ...

Sustainable Overproduction of the Bacterial Pigment Indigoidine as a Natural Colorant: Stability Evaluation, Inhibition of Obesity‐Diabetes‐Related Digestive Enzymes, and Activation of AMPK–AKT

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Production of indigoidine (IND) increased from 1.04 to 2.76 g/L using an optimized LB medium composed of glucose, l‐glutamine, tryptone, yeast extract, MgSO4·7H2O, and KH2PO4. The IND has significant inhibition properties against amylase and lipase enzymes, stimulates AMPK and AKT pathways, and improves glucose uptake.

Photodegradation of Azo and Hydrazone Colourants on Cellulose‐Based Materials: A Mass Spectrometric Screening

ChemistrySelect, Volume 11, Issue 37, 6 October 2026.
Natural‐light ageing of early azo dyes and hydrazone pigments (AY36, AO7, and AR1) on cellulose‐based supports produces marked chromatic changes and distinct molecular transformations. LC–HRMS analysis of aged AY36 reveals degradation products associated with N‐oxidation, N‐dearylation, azo‐bond oxidation, and formaldehyde addition, providing a first ...
