Introduction: Cocamidopropyl betaine (CAPB) is an amphoteric surfactant commonly used in rinse-off cosmetic products. There is still a debate concerning the actual allergen in CAPB.
Objective: To evaluate the prevalence of CAPB allergy and its characteristics among Israeli patients.
Methods: A hundred consecutive patients with suspected cosmetic allergy were patch tested. They underwent standard and cosmetic series patch tests.
Results: Six patients, all females, were allergic to CAPB. Relevance rate was 66%. No significant characteristics were found among allergic patients.
Conclusion: The rate of CAPB allergy is similar to the prevalence worldwide. CAPB became one of the leading causes of cosmetic allergy.

Despite extensive research on the use of salts to enhance micellar growth, numerous questions remain regarding the impact of ionic exchange and molecular structure on charge neutralization. This study looks into how certain cations (Na, Ca, and Mg) affect the structure of a cocamidopropyl betaine CAPB and sodium dodecylbenzenesulfonate SDBS surfactant mixture, aiming toward applications in targeted delivery systems. The mixture consists of a zwitterionic surfactant, cocamidopropyl betaine (CAPB), and an anionic surfactant, sodium dodecylbenzenesulfonate (SDBS), combined in varying molar ratios at a total concentration of 200 mM.

Contact allergy (CA) is a frequent condition in children; however, newer estimates of the prevalence of CA in children are lacking. Herein, we aim to provide an estimate of the prevalence of CA in children from 2010 to 2024. Two authors independently searched PubMed, Embase and Web of Science for studies reporting the prevalence of positive patch tests (PPTs) to allergens in populations including ≥ 100 children (< 18 years).

Bacterial spores pose significant risks to human health, yet the inactivation of spores is challenging due to their unique structures and chemical compositions. This study investigated the synergistic effect between surfactants and chlorine on the inactivation kinetics of Bacillus subtilis spores. Two surfactants, cocamidopropyl betaine (CAPB) and cetyltrimethylammonium chloride (CTMA) were selected to investigate chlorine disinfection in absence and presence of surfactants.

Personal care product usage is becoming increasingly prevalent among men due to evolving attitudes surrounding appearance, aging, and masculinity. Given the specific characteristics of male skin compared with female skin and varying product use between males and females, the occurrence of allergic contact dermatitis (ACD) due to men's personal care products needs to be better characterized. The purpose of this review was to identify specific product types and ingredients causing ACD in males.

The unpredictable biodegradation of fluorotelomer (FT)-based per- and polyfluoroalkyl substances (PFAS) causes complicated risk management of PFAS-impacted sites. Here, we have successfully used redundancy analysis to link FT-based precursor biodegradation to key microbes and genes of soil microbiomes shaped by different classes of carbon sources: alcohols (C2-C4), alkanes (C6 and C8), an aromatic compound (phenol), or a hydrocarbon surfactant (cocamidopropyl betaine [CPB]). All the enrichments defluorinated fluorotelomer alcohols (:2 FtOH; = 4, 6, 8) effectively and grew on 6:2 fluorotelomer sulfonate (6:2 FtS) as a sulfur source.
