Essential Oil Microcapsules Immobilized on Textiles and Certain Induced Effects

Area of Science:

• Materials Science
• Textile Engineering
• Cosmetic Science

Background:

• Development of advanced textile materials for cosmetic applications is a growing field.
• Microencapsulation offers a method to impart active ingredients onto textiles.
• Enhancing fabric properties requires effective methods for microcapsule deposition and fixation.

Purpose of the Study:

• To investigate the deposition of rose and sage microcapsules onto cotton and poly-cotton woven fabrics.
• To evaluate the physical-mechanical characteristics and durability of the functionalized textile materials.
• To assess the in vitro biocompatibility of the microcapsule-functionalized fabrics on human dermal fibroblasts.

Main Methods:

• Padding deposition of rose and sage microcapsules on cationized cotton and poly-cotton fabrics.
• Fixation of microcapsules using an acrylate-based binder.
• Characterization of physical-mechanical properties and microcapsule distribution (SEM) before and after washing/abrasion.
• In vitro biocompatibility testing (cell viability, membrane integrity, inflammation, cell morphology) on CCD-1070Sk fibroblasts.

Main Results:

• Successful deposition and fixation of rose and sage microcapsules on both fabric types.
• Microcapsule distribution remained largely intact after five washing cycles and 1000 abrasion cycles.
• Functionalized fabrics exhibited no significant cytotoxicity, inflammation, or negative impact on cell morphology in vitro.
• Physical-mechanical properties of the fabrics were maintained post-functionalization.

Conclusions:

• Rose and sage microcapsules can be effectively applied to cotton and poly-cotton textiles for cosmetic applications.
• The functionalized textiles demonstrate good durability and are biocompatible with human skin cells.
• These findings support the potential of these innovative textiles for further in vivo development and use in cosmetic products.
