Calcium carbonate
for pharmaceutical applications

Not only the active substance is decisive, it also depends on the excipient

In order to give phar­ma­ceu­ti­cal prepa­ra­tions deci­sive pos­i­tive prop­er­ties, also the excip­i­ents are of great impor­tance besides the active ingre­di­ent. They have an influ­ence on the final prod­uct and act as fillers, emul­si­fiers, preser­v­a­tives, binders, coat­ing and much more.

The min­er­al cal­ci­um has many pos­i­tive effects on the organ­ism. Among oth­er things, it affects the excitabil­i­ty of mus­cle cells, is an impor­tant build­ing block for bones and teeth and can con­tribute to the pre­ven­tion of osteoporosis.

In phar­ma­ceu­ti­cal for­mu­la­tions the impor­tant min­er­al is indis­pens­able in the form of syn­thet­ic cal­ci­um car­bon­ate (PCC=precipitated cal­ci­um car­bon­ate). As an inert filler, cal­ci­um car­bon­ate is hard­ly sol­u­ble even in pure water. Due to its bright white col­or, it is a per­fect pig­ment sup­pli­er and there­fore an attrac­tive sub­sti­tute for tita­ni­um dioxide.

Do you use cal­ci­um car­bon­ate in your pro­duc­tion?
Are the fol­low­ing terms part of your dai­ly work routine?

Filler with high whiteness

Then we should talk about cal­ci­um carbonate.

With our grades MAGNESIA 4421 and MAGNESIA 4461, we offer two pre­cip­i­tat­ed cal­ci­um car­bon­ates in EP qual­i­ty that per­fect­ly match for use in phar­ma­ceu­ti­cal formulations.

Do you want to know how cal­ci­um car­bon­ate, as an effi­cient phar­ma­ceu­ti­cal excip­i­ent, offers real added val­ue in your for­mu­la­tions? Then con­tact our Phar­ma­ceu­ti­cals-team. We are hap­py to advise you. On request, we will send you a cor­re­spond­ing sample.
