Identifying The Need
Polymers and waxes are usually employed by the pharmaceutical industry for coating solid dosage forms. However, since waxes have poor water affinity, their use is restricted as a molten liquid form that involves application of heat and requires special equipment for coating or as solutions in organic solvents that have environmental and cost implications. Hence a need arises to develop technology which can overcome these limitations, so that waxes can be used for various coating applications in pharmaceutical products.

The Rubicon Research Solution
Rubicon Research's RubiCoat
TM technology offers a stable, smooth, aqueous dispersion of wax that can be employed for coating, using conventional equipments. RubiCoatTM comprises of a wax or a combination of waxes emulsified in water using an emulsifying agent. A plasticiser is included to facilitate the formation of a continuous uniform film. RubiCoatTM can be utilised effectively for stabilisation of drugs, delayed, pulsatile and extended release of active ingredients, taste-masking, product identification and various other functions.
