|---|---|---|---|---|
Pros | Cons | Pros | Cons | |
Agarose gel | Easy application and removal Optimal surface contact | Poor inherent surface cleaning Release of water onto the surface | Not tested due to rigidity | Temperature of application higher than glass transition temperature of the uppermost p(nBA-MMA) coating |
PVAc-Borax gel | Easy application and removal Good initial surface contact | Minimal cleaning efficacy Loss of contact with the surface Not compatible with surfactant concentrations higher than 0.5% w/w | Easy application and removal Good initial surface contact | Minimal cleaning efficacy Loss of contact with the surface Not compatible with surfactant concentrations higher than 0.5% w/w |
Xanthan gum (gel only) | Optimal surface contact Moderate inherent cleaning efficacy Modifiable activity | Small areas at a time Several clearance steps required Time-consuming | Optimal surface contact Promising cleaning efficacy Modifiable activity | Small areas at a time Several clearance steps required Mechanical action required Time-consuming |
Shin-Etsu KSG350z emulsion | Optimal surface contact Moderate inherent cleaning efficacy Modifiable activity | Small areas at a time Several clearance steps required Time-consuming Clearance with silicone solvents Requires portable extraction and personal protective equipment (PPE) | Optimal surface contact Promising cleaning efficacy Modifiable activity | Small areas at a time Several clearance steps required Mechanical action required Time consuming Clearance with silicone solvents Requires portable extraction and PPE |
Nanorestore Gel® Peggy 5 gel | Easy application and removal Promising cleaning efficacy Modifiable activity | Moderate surface contact Uneven cleaning efficacy | Easy application and removal, no mechanical action required Promising cleaning efficacy Modifiable activity | Loss of contact with the surface Uneven cleaning efficacy |
Nanorestore Gel® Peggy 6 gel | Easy application and removal Modifiable activity Better contact than Nanorestore Gel® Peggy 5 | Moderate surface contact Uneven cleaning efficacy | Easy application and removal, no mechanical action required Promising cleaning efficacy Modifiable activity | Loss of contact with the surface Uneven cleaning efficacy |
Boots sponge | Gentle mechanical action possible, control of amounts of liquid | Extensive rinsing required prior to use Release of large amount of liquids on the surface | Not tested | Not tested |
NYX Pro Beauty Wedges | As for Boots sponge. Firm consistency No abrasion or resistance when applied to the surface | Release of some liquid on the surface | Not tested | Not tested |
SENSAI sponge cloth | As for Boots sponge. Very absorbent Good control over the cleaning action No abrasion or resistance when applied to the surface | Release of some liquid on the surface | Not tested | Not tested |
