L'Isododecano è un idrocarburo incolore e inodore utilizzato principalmente come solvente e fragranza nelle formulazioni cosmetiche e per la cura personale. È apprezzato per la sua texture leggera e non grassa, rendendolo ideale per prodotti come fondotinta, rossetti e trattamenti per la pelle.
Composizione Chimica e Struttura
La composizione chimica dell'Isododecano include:
Strutturalmente, l'Isododecano è un idrocarburo saturo, caratterizzato dalla sua configurazione ramificata che contribuisce alla sua efficacia come solvente ed emolliente.
Proprietà Fisiche
Processo di Produzione
Applicazioni
Funzioni INCI:
Fragranza. Ha un ruolo decisamente importante nella formulazione di prodotti cosmetici in quanto consente di migliorare, mascherare o aggiungere profumo al prodotto finale aumentandone la commerciabilità. Il consumatore si aspetta sempre di trovare un profumo gradevole in un prodotto cosmetico.
Solvente. E' la sostanza che consente di sciogliere o disperdere, in soluzione, tensioattivi, oli, coloranti, aromi, conservanti battericidi.
Considerazioni Ambientali e di Sicurezza
L'Isododecano è generalmente considerato sicuro per l'applicazione topica nei cosmetici quando utilizzato secondo le linee guida raccomandate. È ben tollerato dalla maggior parte dei tipi di pelle, ma le persone con sensibilità agli idrocarburi dovrebbero esercitare cautela. È essenziale garantire pratiche di approvvigionamento e produzione responsabili per assicurare che l'ingrediente sia privo di contaminanti nocivi e prodotto in modo sostenibile.

Abstract. Epicuticular wax is an example of a naturally created functional material that forms a layer on the outermost surface of plants with the objective to protect them from adverse environmental conditions, such as UV–solar radiation, uncontrolled water loss, microbial attacks, and so forth. Their functionalities are often attributed to the chemical composition of the wax as well as the physical structuration formed by the wax crystals on the surface. With this work, we present a simple, one-step biomimetic approach to replicate similar surface structures, on model substrate, using wax extracted from Euphorbia Cerifera (Candelilla wax). First, we describe formation of structured wax due to self-assembly induced by evaporative drying on quartz plates. Subsequently, we highlight the fundamental physical parameters required to tune the surface morphology. Our experiments reveal that it is possible to achieve considerably diverse surface morphologies depending on the solvent properties and deposition temperature. This diversity is due to the kinetics of recrystallization of wax during evaporation of solvent which, in turn, is primarily driven by the solubility of wax as well as evaporation rate of the solvent. Thus, the final morphology that we obtain is an interplay between recrystallization kinetics and solvent evaporation. Additionally, the degree of crystallinity of the structured films could also be tuned by solvent polarity. Surprisingly, X-ray diffraction indicates that the crystalline structure at the molecular level remains similar to that of bulk Candelilla wax. Our results provide fundamental insights into the replication of epicuticular wax films and identification of tuning parameters to obtain different surface morphologies with the same wax material for potential bioinspired multifunctional coatings in cosmetic applications.

Abstract. A perfluoropolyether (PFPE)-based microfluidic device with cross-junction microchannels was fabricated with the purpose of producing uniform droplets. The microchannels were developed using CO2 laser engraving. PFPE was chosen as the main material because of its excellent solvent resistance. Polyethylene glycol diacrylate (PEGDA) was mixed with PFPE to improve the hydrophilic properties of the inner surface of the microchannels. The microchannels of the polydimethylsiloxane microfluidic device had a blackened and rough surface after laser engraving. By contrast, the inner surface of the microchannels of the PFPE-PEGDA microfluidic device exhibited a smooth surface. The lower power and faster speed of the laser engraving resulted in the development of microchannels with smaller dimensions, less than 30 μm in depth. The PFPE and PFPE-PEGDA microfluidic devices were used to produce uniform water and oil droplets, respectively. We believe that such a PFPE-based microfluidic device with CO2-laser-engraved microchannels can be used as a microfluidic platform for applications in various fields, such as biological and chemical analysis, extraction, and synthesis.
