AI Article Synopsis
- Rubber gloves often have rubber accelerators that can cause allergic reactions, but their specific content is not well understood.
- A study tested 51 gloves from various brands, finding that 90% of disposable gloves contained sensitizing rubber accelerators, particularly zinc dibutyldithiocarbamate (ZDBC) and zinc diethyldithiocarbamate (ZDEC).
- The research highlights the need for better labeling of rubber gloves, as even those claimed to be free of accelerators were found to have them, necessitating more transparency from manufacturers.
Article Abstract
Background: Rubber gloves contain rubber accelerators that may cause contact allergy. The content of sensitising rubber accelerators in contemporary rubber gloves is not well known.
Objectives: Identify and quantify the content of rubber accelerators in disposable rubber gloves.
Methods: Fifty-one gloves of 49 different brands were collected. Forty-eight of the gloves were disposable and three re-usable. The gloves were analysed for their content of sensitising rubber accelerators, that is, zinc dithiocarbamates, thiurams, thiazoles/benzothiazoles, diphenylguanidine, and thioureas by high-performance liquid chromatography.
Results: Rubber accelerators were identified in 43/48 (90%) of the disposable gloves. In total, 39 gloves contained zinc dibutyldithiocarbamate (ZDBC) (0.18-1.96 mg/g), 34 zinc diethyldithiocarbamate (ZDEC) (0.032-2.78 mg/g), three zinc dibenzyldithiocarbamate (0.65-1.4 mg/g), one zinc dimethyldithiocarbamate (0.23 mg/g), and one 1,3-diphenylguanidine (0.21 mg/g). 2-cyanoethyl dimethyldithiocarbamate (CEDMC) was identified in three gloves (<0.052 mg/g). The one glove labelled as accelerator free contained ZDBC (1.07 mg/g). Only few glove packages had the specific content of rubber accelerators labelled.
Conclusions: The most frequent rubber accelerators in rubber gloves are ZDEC and ZDBC. Accelerator-free gloves may contain rubber accelerators. Full labelling of rubber gloves is needed and producers should be sure not to falsely claim that the rubber gloves are free of rubber accelerators.

Enhancing gait mechanics: The effectiveness of a novel walking aid.

Background: A walking support orthosis known as the e-foot®, a rubber orthotic worn from the hip to the forefoot to enhance joint flexibility and movement, has been developed to assist elderly people and individuals with walking impairments. Despite its widespread acceptance and positive reception in some care settings, the precise impact of this device on gait dynamics remains unexplored. This study aims to bridge this gap by comparing the walking speeds of healthy volunteers using the e-foot® against their normal walking speeds.

Conventional floating bridge systems used during emergency repairs, such as during wartime or after natural disasters, typically rely on passive rubber bearings or semi-active control systems. These methods often limit traffic speed, stability, and safety under dynamic conditions, including varying vehicle loads and fluctuating water levels. To address these challenges, this study proposes a novel Hydraulic Self-Adaptive Bearing System (HABS).

Microplastics (MPs) are a growing problem worldwide. Soils are long-term storage sinks of MPs because of the many pathways they enter the soil and their long degradation period. Knowing how MPs influence soil organisms, the effects of organisms on the fate of MPs, and what this means for soil additions, losses, transformations, and translocations is paramount.

Wound healing is a complex process involving a sequence of factors that can be disrupted, negatively impacting the quality of life for patients and overburdening healthcare systems. Advanced dressings obtained by electrospinning are highlighted by the optimization of this process, allowing air exchange and protection against microorganisms. Aiming to develop bioactive dressings, this study investigated the physicochemical, mechanical, microbiological, and in vitro biological properties of membranes containing 25 %, 50 %, 75 %, and 90 % copaiba oil (CO) co-electrospun with poly(L-co-D,L-lactic acid) (PLDLA) and natural rubber latex (NR).

The achievement of sufficient dispersion of vulcanization accelerators is critical to tailoring superior cross-linked elastomers. Modern recipes rely on multicomponent formulations with silica particles covered by coupling agents. We study the molecular properties of select accelerators in polyisoprene melts and their affinity for functionalized surfaces via extensive all-atom molecular dynamics simulations.
