NOVEL MATERIALS WITH MICROENCAPSULATED ESSENTIAL OILS, POTENTIAL APPLICATIONS FOR SKIN CELLULAR REGENERATION DRESSINGS
Abstract
Biopolymers have gained notoriety due to their unique physical, chemical, and mechanical characteristics and performances. Due to their regenerability, compostability, biocompatibility, non-immunogenic, non-toxic, or non-allergenic properties, they have surpassed the boundaries of the food industry and have become fundamental components in biomedicine or the pharmaceutical industry. Thus, the most well-known applications are as drug delivery systems, tissue engineering, or wound dressings. In addition to all these characteristics, biopolymeric films have proven to be excellent matrices for incorporating various biologically active substances: natural compounds, essential oils, antioxidants, etc. The present study aimed to develop sodium alginate films, with the addition of tea tree and chamomile essential oils capsules. After development through the casting method, the materials were tested for evaluate the physical properties (thickness, retraction ratio, color, transparency, opacity), chemical properties (antioxidant characteristics), mechanical properties (tensile strength and elongation), as well as solubility (water activity index, swelling index, water absorption capacity). The results indicated that alginate based - materials with the addition of essential oils capsules can be used in the pharmaceutical and cosmetic industries for developing films with regenerative properties. Similarly, other biologically active substances can be incorporated, and the development technology can be easily scaled up to an industrial level.
