Taro Mucilage: Extraction, Characterization, and Application in Cosmetic Formulations

Taro mucilage, a hydrocolloid present in the rhizome of Colocasia esculenta (L.) Schott, was extracted and characterized by infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermal analysis, and proximal composition. In addition, cosmetic formulations based on extracted mucilage were developed and studied. The mucilage presented a semicrystalline structure with high thermal stability, the presence of granules along its surface area, and good emulsifying activity. High physical-chemical stability was also found in the mucilage and the cosmetic formulations during storage. All cream samples presented pseudoplastic behavior, with a flow behavior index lower than 1, which is a desirable characteristic for cosmetics, as it improves its applicability. The mucilage demonstrates potential for application in cosmetic products, and its commercial use as an ingredient in cosmetics could be a strategic tool for the creation of a new product chain and adding value to the culture of Colocasia0 esculenta.
