Hydroxypropyl Methylcellulose (HPMC)
HPMC is a highly pure cotton cellulose raw material, prepared under alkaline conditions by special etherification. It appears as a white or whitish powder. Its surface activity, water solubility, and gel point vary with the methoxide content. Features include thickening ability, salt resistance, low ash content, pH stability, excellent water retention, and film-forming properties.
