using HPMC

When using hydroxypropyl methylcellulose (HPMC), the following key considerations should be taken into account to ensure its performance and safety: 1. Dissolution Method and Concentration Control Adequate Agitation: When preparing HPMC solutions, ensure adequate agitation to prevent clumping and achieve the desired viscosity. Low-viscosity products (viscosity less than 4,000 mPa·s) can be prepared at a
