Ashland also offers an artificial, neural networking solution, CRWizard™ controlled-release expert tool for formulation or release-profile prediction. Our history of formulation development has generated an extensive data set that can be used to predict the best possible starting formulation for any active pharmaceutical ingredient. To make use of our expertise, please contact us.
Binder selection is critical for robust tablet formulation. Through reasearch, Ashland gained a deeper understanding of the physics of tablet binding, which led to the development of practical tools to assist in binder selection. These tools combined with the exceptional range of Ashland binders, helps you minimize the risk of selecting the wrong binder. Ashland produces binders for wet granulation, dry granulation, direct compression and roller compaction to fit your manufacturing needs.
Poorly water-soluble active pharmaceutical ingredients (APIs) pose ongoing development challenges. Common techniques to improve API solubility, such as salt formation and particle-size reduction, do not always result in the solubility levels required to achieve desired bioavailability.
Ashland pharmaceutical scientists have extensive expertise in the development and manufacture of spray-dried and hot melt-extruded solid dispersions. Over the past 15 years, our contract-services group developed formulations for more than 100 poorly water-soluble compounds. Our Centers of Excellence in Wilmington, DE and Hydrabad, India, offer proof-of-concept services using enabling technologies such as spray drying and hot-melt extrusion. Our São Paulo, Brazil, technical center also offers assistance in evaluating Ashland polymers for hot-melt extrusion. Our technical service scientists are also available for on-site consultations.
Ashland’s line of fully formulated, easily dispersed and ready-to-use Aquarius™ film-coating systems have a range of functions to suit almost any tablet core. Aquarius film-coating systems present an optimum balance of film strength and adhesion, even on challenging cores. The Aquarius Preferred HSP and HSC coating systems are sprayable at 20% solids, for faster throughput and reduced labor and energy costs compared with conventional, lower-solids coatings.
Aquarius film coating systems deliver a smooth, defect-free appearance complete with crisp logo definition in clear, white, pearlescent or full-color formulations and can be customized to address special needs.

Effective tablet disintegration is necessary for active pharmaceutical ingredient (API) dissolution and release. Polyplasdone™ crospovidone, a synthetic, cross-linked polymer, provides rapid disintegration and dissolution of oral solid-dosage forms, even at low use levels; thus also making it effective for high dose formulations. Available in two particle sizes. it provides formulation flexibility for small and large tablets as well as intragranular and extragranular applications. Polyplasdone crospovidone combines rapid swelling with wicking (porosity and capillary action) mechanisms. The high compactability and rapid disintegration of Polyplasdone crospovidone make it a good choice as a multifunctional tablet disintegrant.
Unlike other disintegrants that can gel at high use levels, Polyplasdone crospovidone does not retard API release making it especially beneficial for orally disintegrating tablet (ODT) formulations that have short disintegration time requirements.
Because of its nonionic nature, Polyplasdone crospovidone does not impede dissolution of cationic APIs Polyplasdone XL-10 crospovidone offers uncommon benefits:
- small particle size and rapid disintegration make it a preferred product for (ODT) formulations.
- a high surface area and unique chemistry that enhances the dissolution of poorly water-soluble APIs when compared with other disintegrants.
Polyplasdone Ultra crospovidone is high-purity crospovidone, manufactured and packed under inert conditions for use with active pharmaceutical ingredients that may be sensitive to oxidation or as a precaution where this may be a concern. To preserve the integrity of the inert environment, please refer to the product sampling and handling guidelines.
Oral Liquid Dose
Ashland helps the medicine go down
A spoonful of sugar may help the medicine go down, but the folks at Ashland, with their expertise in pharmaceutical formulations, know that there's more to it. Effective drug delivery in liquid form, poses some unique challenges with rheology, texture, consistency and stability at the top of the list. Ashland's motto - We are solvers - is also our attitude and goal and we want to work with you to find new sophisticated solutions to advance drug delivery. With our extensive polymer portfolio, R&D capaitilities and testing facilities combined with your complex drug molecues can yield solutions for effective, useable ways to deliver and improve the bioavailability of needed medication.
Targeted rheology, texture and stabilization in oral-liquid dosage forms play vital roles in delivery of the pharmaceutical components. The water binding and viscosity modification capacities of many of Ashland’s polymers thicken and suspend in liquids, gels, syrups and semi-solid dosage forms for improved patient satisfaction and shelf life of products.

Solutions that are more than skin deep
Our solutions are more than skin deep. Through transdermal and topical applications, skin can be an effective way to deliver some medications. Regardless of whether the drug is being delivered via gel, lotion, cream, ointment or foam, features including texture, adhesion, and spreadability, as well as feel and smell, are important attributes to consider for optimal patient compliance. For topical and transdermal application, Ashland's pharmacuetical team works with the talented skin care team to find alluring and luxurious ways to effectively and efficiently formulate topical and transdermal applications.
Topical treatments are administered to skin or mucous membranes to alleviate a variety of conditions. These treatments broadly encompass creams, foams, gels, lotions and ointments. There are a number of sought-after attributes for conferring desired properties to a topical formulation: rheology control, spreadability, adhesion and diffusion control. Ashland offers high-quality cellulose ethers such as Natrosol™ 250 hydroxyethylcellulose, Klucel™ hydroxypropylcellulose and Aqualon™ sodium carboxymethylcellulose to deliver these properties. Some of the topical film formers offered in our skin-care product lines are also suitable for use in topical applications. Plasdone™ povidone is also a good film former for topical applications.
