Abstract

The demand for natural-based formulations in chronic wound care has increased, driven by the need for biocompatible, safe, and effective treatments. Natural polysaccharide-based emulsions enriched with vegetable oils present promising benefits for skin repair, offering structural support and protective barriers suitable for sensitive wound environments. This study aimed to develop and evaluate semisolid polysaccharide-based emulsions for wound healing, incorporating avocado () and blackcurrant () oils (AO and BO, respectively). Both gellan gum (GG) and -carrageenan (KC) were used as stabilizers due to their biocompatibility and gel-forming abilities. Four formulations were prepared (F1-GG-AO; F2-KC-AO; F3-GG-BO; F4-KC-BO) and evaluated for physicochemical properties, spreadability, rheology, antioxidant activity, occlusive and bioadhesion potential, biocompatibility, and wound healing efficacy using an in vitro scratch assay. The pH values (4.74-5.06) were suitable for skin application, and FTIR confirmed excipient compatibility. The formulations showed reduced occlusive potential, pseudoplastic behavior with thixotropy, and adequate spreadability (7.13-8.47 mm/g). Lower bioadhesion indicated ease of application and removal, enhancing user comfort. Formulations stabilized with KC exhibited superior antioxidant activity (DPPH scavenging) and fibroblast biocompatibility (CC 390-589 µg/mL) and were non-hemolytic. Both F2-KC-AO and F4-KC-BO significantly improved in vitro wound healing by promoting cell migration compared to other formulations. These findings underscore the potential of these emulsions for effective wound treatment, providing a foundation for developing skin care products that harness the therapeutic properties of polysaccharides and plant oils in a natural approach to wound care.

摘要

由于对生物相容性好、安全且有效的治疗方法的需求,慢性伤口护理中对天然配方的需求有所增加。富含植物油的天然多糖基乳液对皮肤修复具有潜在益处,可为敏感伤口环境提供结构支持和保护屏障。本研究旨在开发和评估用于伤口愈合的半固体多糖基乳液,其中分别加入了鳄梨油(AO)和黑加仑油(BO)。结冷胶(GG)和κ-卡拉胶(KC)因其生物相容性和凝胶形成能力而被用作稳定剂。制备了四种配方(F1-GG-AO;F2-KC-AO;F3-GG-BO;F4-KC-BO),并使用体外划痕试验评估其物理化学性质、铺展性、流变学、抗氧化活性、封闭性和生物粘附潜力、生物相容性以及伤口愈合功效。pH值(4.74 - 5.06)适合皮肤应用,傅里叶变换红外光谱(FTIR)证实了辅料的相容性。这些配方显示出降低的封闭潜力、具有触变性的假塑性行为以及足够的铺展性(7.13 - 8.47 mm/g)。较低的生物粘附性表明易于涂抹和去除,提高了使用者的舒适度。用KC稳定的配方表现出卓越的抗氧化活性(二苯基苦味酰基自由基(DPPH)清除能力)和成纤维细胞生物相容性(半数细胞毒性浓度(CC)为390 - 589 µg/mL),且无溶血现象。与其他配方相比,F2-KC-AO和F4-KC-BO通过促进细胞迁移显著改善了体外伤口愈合。这些发现强调了这些乳液在有效伤口治疗方面的潜力,为开发利用多糖和植物油治疗特性的天然伤口护理护肤品奠定了基础。
