    The Dual Power of Modified Starches in Medicine and Beauty

     

    HPMC is derived from cellulose, the primary structural component of plant cell walls. The modification process involves the alkylation and hydroxyalkylation of cellulose using propylene oxide and methyl chloride. This leads to the introduction of hydroxypropyl and methyl groups into the cellulose chain, resulting in a polymer that is soluble in water and exhibits varying degrees of viscosity and gelation properties based on the degree of substitution.

    Moreover, the growing awareness of environmental issues is likely to drive increased demand for biodegradable materials like PVA. Governments and organizations worldwide are implementing stricter regulations on plastic use, pushing industries to explore alternatives that align with sustainable development goals. As such, PVA is poised to play a pivotal role in the transition towards greener materials.
