Abstract
Background
Acrylate polymers and cross-polymers (ACPs) are frequently used cosmetic ingredients. The British Society for Cutaneous Allergy (BSCA) and the UK Cosmetic, Toiletry and Perfumery Association (CTPA) collaborated to investigate the allergenic potential of three commonly-used ACPs.
Objectives
The objective of this study is to determine the prevalence of allergic contact dermatitis (ACD) to three ACPs: glyceryl acrylate/acrylic acid co-polymer, sodium polyacrylate, and acrylates/C10-30 alkyl acrylate cross-polymer (Carbopol®).
Materials and Methods
The BSCA prospectively audited data collected from 20 centres in the UK and Ireland between 1st September 2021 and 1st September 2022. Patients with suspected ACD to (meth)acrylates, with facial dermatitis, or consecutive patients, were patch tested to glyceryl acrylate/acrylic acid co-polymer 10% aqueous (aq.) sodium polyacrylate 2% aq., and to acrylates/C10-30 alkyl acrylate cross-polymer 2% aq. (Carbopol®). The frequencies of positive, irritant, and doubtful reactions were recorded.
Results
In total, 1302 patients were patch tested. To glyceryl acrylate/acrylic acid co-polymer, there was one doubtful reaction in a patient allergic to multiple (meth)acrylates, and one irritant. To sodium polyacrylate, there were four irritant reactions, one doubtful, and one positive reaction; in all cases, relevance was unknown and there was no demonstrable (meth)acrylate allergy. There were no reactions to Carbopol®.
Conclusions
Sensitisation to these concentrations of the three tested ACPs is rare. Elicitation of dermatitis in (meth)acrylate-sensitised patients by exposure to these three ACPs appears unlikely.
期刊介绍：
ACS Applied Energy Materials is an interdisciplinary journal publishing original research covering all aspects of materials, engineering, chemistry, physics and biology relevant to energy conversion and storage. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrate knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important energy applications.
