It can also be applied in a well-controlled way. Nevertheless, numerous factors must be taken into account during mixing to ensure sterile and efficient production.<\/p><p>Incorporating Carbopol in powder form requires a multi-stage mixing process. In addition, certain speeds must be maintained and air entrapment avoided.<\/p><h2>Requirements for the homogenising mixer<\/h2><p>For induction and <a href=\"\/homogenisation\/?lang=en\">homogenisation<\/a> to run smoothly and conveniently, the mixer must incorporate and wet powders evenly. The following features are particularly important:<\/p><ul class=\"svt-checks\"><li>powder feeds that prevent lumps from forming<\/li><li>low speed when <a href=\"\/solid-liquid-mixing\/?lang=en\">adding powders to the liquid phase<\/a>, so that no air gets into the gel<\/li><li>variable speed for agitator and homogeniser for efficient <a href=\"\/agitation\/?lang=en\">agitation<\/a> and homogenisation<\/li><li>vacuum-controlled induction of liquids and powders into the circulation flow below the liquid level<\/li><\/ul><p>Vacuum-controlled induction significantly shortens process times and reduces air entrapment. At the same time, product quality increases.<\/p><h2>FAQ: Producing pharmaceutical gels<\/h2><h3>How is Carbopol incorporated into a gel without lumps?<\/h3><p>The powder is added slowly at low speed, ideally sucked in under vacuum below the liquid level into the homogeniser, so every particle is wetted individually.
