Abstract
Aesthetic perforations are often associated with health issues, such as itching, inflammation, or microbial infection. Accordingly, this work proposed a lacquer to be applied on the adornment accessory forming a film from which a proper drug is released. For this, lacquers were formulated containing three different permeation enhancers (limonene - LIM, propylene glycol - PG, and oleic acid - AO) combined according to a mixture design with a model anti-inflammatory natural drug (naringenin) and a soluble film-former polymer (polyvinyl alcohol). Formulations were characterized by physicochemical tests and in vitro and in vivo skin permeation studies. The lacquers were stable and provided a vectorized drug release. LIM, combined with one of the other permeation enhancers, showed a synergic effect, enhancing topical skin penetration in vitro by 53% while preventing permeation to the receptor medium. The in vivo evaluation of lacquers in rodent models showed these systems could provide higher levels of drug retention in the ear (166.4 ± 14.9 µg per ear for F4 and 174.9 ± 29.3 µg per ear for F5) compared to the control (109.2 ± 16.3 µg) without allowing its permeation into the bloodstream, confirming the local drug delivery. Moreover, the anti-inflammatory activity was achieved in the animal model developed for lacquer application on the earring, obtaining inhibition of ear swelling up to 40.8% ± 2.3 compared to the untreated ear. Thus, such an innovative lacquer proved a promising vehicle for treating affections caused by adornments, enhancing skin permeation while avoiding a systemic effect.

Abstract
A homologous series of Gemini surfactants, dimethylene-1,2-bis(alkyldimethyl-ammonium bromide) (referred to as n-2-n·2Br, n = 14, 16, and 18) and Fe- or lanthanide metal-based magnetic Gemini surfactants (abbreviated as n-2-n·2X, X = Fe, Ce, and Gd), were first synthesized. Measurements of surface tension and electrical conductivity determine the physical quantities related to the surface activities of n-2-n·2Br and n-2-n·2X, and the magnetic behaviors of n-2-n·2X are elucidated by superconducting quantum interference device magnetometry. Thermogravimetric analysis and differential scanning calorimetry have been used to investigate thermotropic liquid crystalline properties of all aforementioned surfactants, and the liquid crystal textures were further observed via polarizing optical microscopy. These results reveal that for magneto-responsive Gemini surfactants, both magnetic counterions and alkyl chain lengths have certain effect on surface activities, magnetism, and thermotropic phase behavior. We summed up these changes and discussed the causes, which could provide a new insight into controlling the properties of magnetic surfactants.
