Objective and subjective performance evaluations of wet wipes including herbal components

Abstract

In this study, wet wipes were produced for body applications with nonwoven fabrics consisting of polyester and cellulose (viscose and Tencel®). Fabrics were wetted by natural-based wetting solutions (rose water, olive oil) which were functionalized by sodium alginate and natural antibacterial agents (cinnamaldehyde and geraniol) without preservatives. Besides physical characteristics (weight, thickness, porosity, fiber orientation), bending rigidity, Handle-O-Meter measurements, and moisture management test parameters of the nonwoven fabrics were determined. Subjective hand and wiping performances of produced wipes were determined by subjective evaluations carried out on 10 female subjects. According to the results, 100% Tencel® and its blend with viscose have good absorption and moderate transfer characteristics. Polyester content up to 60% is acceptable for wet wipes for the body according to their liquid absorption, transfer, and subjective evaluation results if fabric weight is sufficient. Among the functionalized wetting solutions, antibacterial performance of the solution including olive oil, sodium alginate and cinnamaldehyde was the maximum and it has acceptable hand values according to objective Handle-O-Meter results and subjective evaluation results.

Bioinspired and eco-friendly high efficacy cinnamaldehyde antibacterial surfaces

“…Antibacterial activities have been reported previously for cinnamaldehyde impregnated into porous substrates including microporous polyurethane, 58 polypropylene foot sweat pads, 79 and wet wipes made from cellulose and polyester. 80 However, no recycle/reuse testing was performed. Impregnation of cinnamaldehyde into porous hydrophobic (non-woven polypropylene cloth and polytetrafluoroethylene membrane) as well as into hydrophilic cotton through cinnamaldehyde entrapment is an effective means for incorporating large amounts of the essential oil into a substrate for multiple use antibacterial applications, Fig.…”

New Trends in Non-Woven Wet Wipes

“…These wipes are consisting of a nonwoven fabric material and a liquid part, which is also known as "juice" or solution of typically water, ethanol-or oil-based, and 90%-98% of the liquid is water in the wipes. The recipe of the liquid for makeup remover wipes are similar to other wet wipes, which includes an emollient to improve the glide of the wipe on the skin and to hydrate the residues to reduce dryness and irritation; a surfactant and/or an emulsifier to emulsify the emollient or any other water insoluble oils present in the composition with the function of breaking down the dirt, oil, or chemicals in the makeup products; a rheology modifier to increase the viscosity of the composition at lower temperatures as well as at process temperatures; a preservative to reduce the growth of microorganisms and to enable a longer shelf life; and a soothing agent to reduce the irritation or stinging/burning/itching effect of chemicals [16,17].…”

Why Are Wet Wipes So Difficult to Preserve? Understanding the Intrinsic Causes

“…The liquid impregnating the wipes is mostly water but also contains surfactants, a buffer, and preservatives. Nonwoven fabrics are broadly defined as sheet or web structures bonded together mechanically, thermally, or chemically by entangling fibers or filaments [1]. The fibers used to produce the wipe may be natural, such as wood pulp, or synthetic, such as polypropylene, polyester (PET), or combinations thereof.…”
