Monolithic (ingredients in adhesive) Patches
What is a monolithic patch, and how do we make it?
In a monolithic patch, the active ingredients and other selected excipients are directly incorporated into the adhesive solution, mixed, cast as a thin film and cured. This leaves a dried adhesive matrix film containing the active ingredient and excipients. This active ingredient in adhesive matrix is sandwiched between release liner and backing layer.
Monolithic patches excel in short-term applications, up to 36 hours. They also allow you to print directly on the patch, maximizing your branding opportunities. While our standard size monolithic patch is a 2″x 2″ rounded square, as a custom manufacturer, we can customize the final size and shape.
The final appearance of monolithic patches is flat, unlike our pad patches.
1: Active Ingredient incorporated into medical-grade acrylic adhesive. This clear mixture is coated onto the patch, and the active ingredients are absorbed into the skin. Color of patch will depend on your active ingredients, as we use a clear film. Yes, active ingredients sometimes have tint!
2: The patch material – this can be soft flesh-tone foam, clear or colored printable material for branding purposes.
3: The liner – this is what you peel the patch off of, prior to applying to the skin.
When selecting your patch, it’s important to consider your desired end-result. What experience do you want your customer to have? How long do you want your customer to experience the benefits of your active ingredients? How important is branding to you? All of these issues will help you decide whether monolithic or pad patches are right for you. We’d love to help you walk through the process – just give us a call!
