Decyl Glucoside è un tensioattivo non ionico delicato derivato da fonti naturali, specificamente dal glucosio del mais e da alcoli grassi. È ampiamente utilizzato nelle formulazioni cosmetiche e per la cura personale per le sue proprietà detergenti ed emulsionanti, adatto per pelli sensibili.
Composizione Chimica e Struttura
La composizione chimica del Decyl Glucoside include:
Strutturalmente, il Decyl Glucoside è un glucoside, composto da un gruppo decilico legato a una molecola di glucosio, che contribuisce alle sue proprietà di tensioattivo.

Processo di Produzione
Applicazioni
Funzioni INCI:
Tensioattivo - Agente di pulizia. I prodotti cosmetici utilizzati per detergere la pelle utilizzano l'azione tensioattiva che produce un abbassamento della tensione superficiale dello strato corneo facilitando la rimozione di sporco e impurità.
Tensioattivo alchil poliglucoside non ionico, stabilizzante, PEG-free, studiato per la stabilizzazione di nanoparticelle (1). Stabile schiumogeno, rapidamente biodegradabile, bassa tossicità, bassa viscosità, basso livello di sali di sodio. Possiede una buona tolleranza agli alcali e tolleranza agli elettroliti.
Utilizzato in cosmetica nei saponi liquidi e shampoo come secondo tensioattivo con un'eccellente stabilità caustica e solubilità in soluzione salina, alcalina e tensioattiva altamente concentrata. In genere è presente l'ossido di magnesio ed il magnesio in misura variabile da 100 ppm a 400 ppm.

Sicurezza
L'estrogenicità del decil glucoside è stata confermata. (2).
Il gruppo di esperti sul controllo degli ingredienti cosmetici (CIR) ha valutato la sicurezza di 19 alchil glucosidi nel modo in cui vengono utilizzati nei cosmetici ed ha concluso che questi ingredienti sono sicuri nelle pratiche attuali di uso e concentrazioni quando formulati per essere non irritanti.(3).

Abstract. Lipid nanoparticles are well-known nanocarriers for improved drug delivery. Their formulation development typically involves three formulations steps. In the first part a suitable lipid mixture which enables a high loading capacity and high encapsulation efficacy of the active needs to be identified (lipid screening). In the second step suitable stabilizers that enable the production of small-sized lipid nanoparticles with narrow size distribution and sufficient physical stability need to be identified (stabilizer screening, optimization of production parameters) and in the third step the biopharmaceutical efficacy needs to be evaluated. Based on the results obtained the formulations will require further optimization. The classical formulation development of lipid nanoparticles and especially the classical lipid screening is tedious. Therefore, in this study, a novel approach for the lipid screening that was based on the determination of the Hansen solubility parameters was evaluated and the results obtained were compared to the results from the classical model. Tacrolimus was used as a model drug. Results showed that both lipid screenings led to similar results, indicating that the new approach can be used for future developments. The optimized formulation was composed of a lipid matrix system that contained waxes, triglycerides and monoacylglycerols with various carbon chain lengths (C8, C10, C16, C18) and enabled an encapsulation efficiency of ~99%. The stabilizer screening showed that surfactants with high HLB values, lower molecular weight, and shorter alkyl chain length tended to form smaller particles with narrower size distribution and better physical stability. The most suitable surfactant was found to be a caprylyl/capryl glucoside (Plantacare® 810), a PEG-free stabilizer, that is extremely mild for atopic skin. It led to particle sizes of about 200 nm and a zeta potential well above |30| mV. The optimized formulation contained 0.1% tacrolimus and possessed good physical stability. In conclusion, an optimized method for the selection of lipids that results in a limited number of experiments could be established and tacrolimus loaded lipid nanoparticles with similar drug load as a marketed formulation was successfully developed in this study.

Abstract. The estrogenicity of decyl glucoside was asserted as a non-endocrine disruptive surfactant with its preparation method using zeolite catalysts. Its estrogenicity was estimated using E-assay method. The decyl glucoside was synthesized by direct glucosidation from D-glucose with 1-decanol. The conversion and yield were improved with increasing of amount of acid sites of the zeolite catalysts. The decyl glucopyranoside is more hydrophilic than nonylphenol and has a high wettability. The decyl glucopyranosides exhibited extremely lower proliferation of estrogenic cell compared with nonylphenol.

Safety assessment of decyl glucoside and other alkyl glucosides as used in cosmetics. Int J Toxicol. 2013 Sep-Oct;32(5 Suppl):22S-48S. doi: 10.1177/1091581813497764
Abstract. The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 19 alkyl glucosides as used in cosmetics and concluded that these ingredients are safe in the present practices of use and concentration when formulated to be nonirritating. Most of these ingredients function as surfactants in cosmetics, but some have additional functions as skin-conditioning agents, hair-conditioning agents, or emulsion stabilizers. The Panel reviewed the available animal and clinical data on these ingredients. Since glucoside hydrolases in human skin are likely to break down these ingredients to release their respective fatty acids and glucose, the Panel also reviewed CIR reports on the safety of fatty alcohols and were able to extrapolate data from those previous reports to support safety.
