“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
HPMC wird durch den durchschnittlichen Substitutionsgrad (DS) sowie das Verhältnis Methyl vs. Hydroxypropyl charakterisiert.[9] In Verbindung mit der allgemeinen Bezeichnung „Hypromellose“ wird dies durch eine vierstellige Zahl symbolisiert, wobei die ersten zwei dem Methoxy-Gehalt entsprechen, die letzten zwei dem Hydroxypropoxy-Gehalt.[10]

In contrast, medium viscosity grades, such as 1000cps and 4000cps, are suitable for oral solid dosage forms like tablets and capsules In contrast, medium viscosity grades, such as 1000cps and 4000cps, are suitable for oral solid dosage forms like tablets and capsuleshpmc viscosity grades. They act as binders and disintegrants, ensuring proper tablet formation and drug release upon consumption. High viscosity grades, such as 15000cps and above, are ideal for controlled-release formulations where extended drug release is desired over an extended period.MK400 FP、MT1004
HPMC and HEC, both of them are a kind of cellulose ether. but what is the difference between them? HPMC VS HEC. In recent years, the output and consumption of HPMC have been increasing rapidly. HPMC is an ironic cellulose ether. it begins refined cotton after alkalization treatment. Propylene oxide and methyl chloride is the etherifying agent in the HPMC manufacturing process. After a series of reactions, get HPMC. But HEC also begins refined cotton after alkalization treatment. With acetone, HEC uses ethylene oxide as the etherifying agent. So HEC has more hydrophilic than HPMC. It is prone to absorb moisture.
