Allergic contact dermatitis to alkyl glucosides: Epidemiological situation in Spain

“…LG, however, could be better placed in a cosmetic/facial series. 2 As described in the literature, most cases of AG contact dermatitis in our study are in women, which could reflect their higher use of cosmetics. 26.7% of the patients had associated atopic dermatitis, but a higher percentage had another atopic comorbidity (up to 33.3% rhinoconjunctivis), similar to other studies published in the literature.…”

“…Among these allergens are alkyl glucosides (AG). 1,2 AG are a family of nonionic surfactants synthesized through the condensation of glucose with long-chain fatty alcohols. 3,4 This makes the AG completely biodegradable, having recently increased their fame due to their ecological nature.…”

“…In the case of LG, a positivity patch test was detected in 0.86% of patients (0.66-1.1). 2 The ESCD recommended in January 2022 the addition of DG to its baseline series. LG, however, could be better placed in a cosmetic/facial series.…”

Hypersensitivity to permanent tattoos: Literature summary and comprehensive review of patch tested tattoo patients 1997–2022

“…Benzisothiazolinone (BIT) is a commonly used industrial biocide (especially in wall paints) and an emerging allergen with a high prevalence of contact allergy all over Europe. 97,98 It is not allowed in cosmetics in the European Union 16 but the most frequent preservative in tattoo and PMU inks. BIT was identified in 15%-35% of the analysed samples in large-scale Swiss analyses between 2011 and 2020, most often without labelling.…”
