As hydroxypropyl methylcellulose comes from non-GMO plants, commonly known as plant-derived empty capsules, the residues of harmful substances are far lower than in traditional gelatine capsules, which themselves do not contain proteins and amino acids, plus the special production and manufacturing process makes it difficult for bacteria to recontaminate and safer without the worry of chlorinated ethanol residues.
The low water content and stable molecular structure of hydroxypropylmethylcellulose empty capsules make them particularly suitable for the filling of Chinese medicinal preparations.
