All products are checked for the regulatory compliance of all ingredients in the target countries and market segments of sale. This determination is made at the time the initial formulation is established, based on customer-supplied information. If market countries and/or segments are extended once the formulation has been established, customers are encouraged to contact us to ensure that regulatory compliance is not compromised.
INSTACOATTM EN HPMC-P is an HPMC-P based ready-to-use enteric coating system for organic solvent use, which provides excellent enteric protection to solid oral dosage forms. Use of a seal coat to prevent interaction between active and polymer and to provide a uniform substrate is recommended.

*Tablet bed temperature offers the most effective way of controlling the coating process. Where this measurement is unavailable, exhaust temperature may be substituted. However, the relationship between the two measurements is complex and depends on several factors such as pan load, pan depression, pan design and airflow rate. Indicated exhaust temperature may be above or below the true bed temperature. It is recommended that the relationship between the two measurements is calibrated.
