INSTANUTE IR is a ready-to-use film coating system in dry powder form for reconstitution in water, based on Hypromellose (HPMC) & dedicated to nutritional applications. It is supplied in a wide range of colours. Selection can be easily made from the INSTANUTE Colour Guide (available on request). INSTANUTE IR can be formulated with aluminium lake, iron oxide and natural pigments. Flavours can also be incorporated.

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.

*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.
