š„ø Ever thought about the role of phospholipids and lipid peroxidation in allergic contact dermatitis?
š Work by Moore et al. has shown that terpene hydroperoxides derived from linalool, geraniol, and limonene can induce phospholipid peroxidation in the cell membrane, with the highest levels of peroxidation being caused by the most potent contact sensitizer.

š§Ŗ New preservative allergy on the rise: Is BIT the next MI?
In a 10-year Danish study, Rebekka SĆøgaard and colleagues report a sharp increase in contact allergy to benzisothiazolinone (BIT)āfrom ā¤0.3% in 2014 to 5.0% in 2023.
š Meanwhile, allergy to methylisothiazolinone (MI) and MCI/MI declined, thanks to EU regulations.
š BITāused in paints, detergents, and industrial productsāremains unregulated in cosmetics but is becoming a major emerging allergen.
ā ļø Urgent need for better regulation and labelling of BIT in non-cosmetic products to prevent a new wave of sensitization.

A new case report by Wimolsiri Iamsumang reveals three patients who developed allergic contact dermatitis from a hair dye marketed as p-phenylenediamine (PPD)-free.
š¬ Chemical analysis showed the product actually contained 2.9% PPDāexceeding legal limits in both Thailand and the EU.
ā ļø This case highlights a serious gap in product labelling and regulation, especially for cosmetic products in global markets.
š A reminder to clinicians: Always test patientsā personal products when allergy is suspected.

š§“ Are āgentleā ingredients triggering allergies in kids?
A new study led by Silada Kanokrungsee using data from Belgium (Antwerp) reports a surprisingly high rate of contact allergy to glucosidesāmild surfactants found in many childrenās shampoos, soaps, and sunscreens.
š Over 11% of children patch-tested showed positive reactions, especially those with atopic dermatitis. Many reactions were weak (+) and possibly false positives, raising concerns about patch test interpretation and product safety.
ā ļø A call for caution when formulating and testing pediatric skincare products.

š Contact allergy to nail products is on the riseādespite EU regulations.
In a 5-year Italian study, Elena Sofia Caroppo and colleagues found an increasing trend of allergic contact dermatitis to 2-HEMA, especially in young women using artificial nail products.
š Among over 7,000 patients patch tested, 2.7% were positive in 2023āup from 1.6% in 2019.
ā ļø Despite 2020 EU restrictions, non-compliant nail products remain widely available, highlighting gaps in enforcement and public health protection.

š§¤ How much is too much? Setting safety thresholds for rubber glove allergens. In a new study led by Christoffer Kursawe Larsen, researchers determined the threshold dose of TETDāa common rubber acceleratorāthat can trigger allergic contact dermatitis.
š Using patch testing and a glove-use simulation, they found an EDāā of just 0.75 Ī¼g/cmĀ². This is far lower than levels found in many rubber gloves on the market.
š¬ The study proposes a standardized test model to better assess allergen safety in protective gear.
