Increasing hydration of the epidermis by microcapsules in sterilized products

Abstract

WileyGisbert Paya, J.; Ibañez García, F.; Bonet Aracil, MA.; Monllorpérez, P.; Díaz-García, P.; Montava Seguí, IJ. (2009) ABSTRACTSome non-serious skin infections can be treated by hydration and antibacterial control. Microcapsules containing aloe-chitin are often used to treat this kind of problem. Microcapsules were applied to cotton fabrics by padding and sleeves were prepared. A hypoallergenic test was applied to the microcapsule emulsion and hydration of the epidermis was evaluated by capacitance methods. The fabric was sterilized by electron beam treatment to satisfy the antibacterial requisite. The results showed that the aloe is transferred from the fabric to the skin, increasing the level of skin hydration. The electron beam method was also shown to be effective for bacteria and fungi and had no effect on the microcapsule properties. It can therefore be confirmed that electron beam sterilization has no harmful effects on the type of microcapsule used in this study.

A comparison between padding and bath exhaustion to apply microcapsules onto cotton

“…Textile manufacturers are concerned about the increasing interest in the application of new properties such as durable fragrances and skin softeners to textiles. Other potential applications include insect repellents, dyes, vitamins, antimicrobials, phase change materials and specific medical applications, antibiotics, hormones, and other drugs (Nelson G. 2002, Monllor P. et al 2007, Nelson G. 1991, Nelson G. 2001, Miro Specos M et al 2010, Gisbert G. et al 2009).…”

“…Nevertheless, some properties such as hydration, insect repellent, antibacterial, etc., cannot be tested without analytical methods. Some characterization techniques have been applied in order to study microcapsule products, presence and state (Monllor P. et al 2007, Gisbert G. et al 2009, Hong K. and Park S. 1999, Rodrigues SN. Et al 2008, Rodrigues SN.…”

Studying bath exhaustion as a method to apply microcapsules on fabrics

“…In other areas such as cosmetics (Gisbert et al, 2009;Kapunsiac et al, 2006) foods (Wegmuller at al. 2006), insecticides (Boh et al 2003; US Patent 2010/0183690 A1), and adhesives (Giroud et al, 1995), they are considered as a potential additive to improve their product properties.…”

“…We can observe a wide variety of active products such as fragrances [Li et al 2006;Nelson, 2001;Monllor et al 2007;Monllor et al, 2010], phase change materials (Fan et al, 2004;Hawlader et al 2003;Xiao_Zheng et al 2003;Zhang et al 2004), dyes (Chang et al, 2003;Sawada et al, 2005), antimicrobial agents (Gisbert et al, 2009;Madene et al, 2006;Nelson, 2002;Wang et al, 2005) etc., which makes microcapsules an attractive field to study and of course patent applications have been increasing. Microcapsule shell is also varied (Madene et al, 2006;Nelson, 2002;Wang et al, 2005), but when it is based on oil materials, amino polymer resins such as melamine formaldehyde or urea formaldehyde have recently gained much attention due to the possibility of increasing oil shelf life and targeted delivery (Long et al, 2009).…”

Electron beam effect on poly (ethylene terephthalate) fibres

“…Electrons can alter various chemical and molecular bonds, including the reproductive cells of microorganisms, so it should be used carefully. Ionizing radiation (gamma and electron beam radiation) is often used for sterilization of polymeric materials (Ferreira et al , 2002; Gisbert et al , 2009).…”
