AquaSolve? hypromellose acetate succinate
AquaSolve? HPMCAS for pharmaceutical applications is a cellulosic polymer with four substituents randomly substituted on the available hydroxyl groups with the following mass content: methoxyl, 12–18 wt%; hydroxypropoxy, 4–23 wt%; acetyl, 2–16 wt% and succinoyl, 4–28 wt%. It is white to off-white in color and has a faint acetic acid-like odor and a barely detectable taste. AquaSolve HPMCAS is available in several grades for pharmaceutical a...
Benecel? methylcellulose and hypromellose
Benecel? methylcellulose and hypromellose (hydroxypropyl-methylcellulose or HPMC) are versatile excipients with a variety of applications. High-viscosity grades are widely used in hydrophilic matrix controlled-release systems. Low-viscosity grades are used for rheology control and as tablet binders. Benecel Grades Available -->
Blanose? sodium carboxymethylcellulose
Blanose™ sodium carboxymethylcellulose (CMC) is made by reacting sodium monochloroacetate with alkalicellulose under rigidly controlled conditions. The resultant anionic polymer is purified and dried. Purified CMC for personal care and cosmetic applications is typically sold at 99.5 percent minimum purity. In addition to thickening aqueous systems, CMC is used in personal care products for water binding, syneresis control and its abil...
CAVAMAX? native cyclodextrins
The molecular structure of cyclodextrins creates a bucket-like cavity that can complex with molecules or functional groups on molecules to improve solubility of poorly soluble compounds. The same mechanism makes these excipients capable of masking unpleasant taste/odor and stabilizing drugs that are prone to degradation. The number of glucose units in the ring determines the internal diameter of the cavity and its volume, as the height of the cyc...
Klucel™ hydroxypropylcellulose (HPC) is a nonionic water-soluble cellulose ether with a remarkable combination of properties. It combines organic solvent solubility, thermoplasticity and surface activity with the aqueous thickening and stabilizing properties characteristic of other water-soluble cellulose polymers available from Ashland. Klucel HPC films are flexible without plasticizers and non-tacky at high humidity.
Natrosol™ hydroxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. It is made by reacting ethylene oxide with alkali-cellulose under rigidly controlled conditions. Purified HEC for personal care and cosmetic applications is typically sold at 95.0 percent minimum purity (dry basis). Solutions of Natrosol HEC are pseudoplastic or shear-thinning. As a result, personal care products formula...

Aqualon™ sodium carboxymethylcellulose (CMC) is made by reacting sodium monochloroacetate with alkalicellulose under rigidly controlled conditions. The resultant anionic polymer is purified and dried. Purified CMC for personal care and cosmetic applications is typically sold at 99.5 percent minimum purity. In addition to thickening aqueous systems, CMC is used in personal care products for water binding, syneresis control and its ability to...
Ashland offers a comprehensive range of Plasdone povidones (PVP). Plasdone povidones are a family of water-soluble polymers based on N-vinylpyrrolidone that combine a unique set of properties for application in a wide variety of dosage forms. Plasdone povidones are commonly used as binders for the development of tablet formulations, whether manufactured by wet granulation, dry granulation or direct compression. Plasdone K polymers are used in sol...
Plasdone? S-630 copovidone
Plasdone™ S-630 copovidone is a tablet binder, matrix polymer for solid-dispersion formulations and film former for topical applications.

Cavitron* cyclodextrin and CAVASOL* cyclodextrin
The molecular structure of cyclodextrins creates a bucket-like cavity that can function to complex with molecules or functional groups on molecules. The substitution of hydroxyl groups on native cyclodextrins to make hydroxypropyl-?- or hydroxypropyl-γ-cyclodextrins (HPBCD or HBGCD) significantly enhances their solubility and makes them more suitable for drug solubilization. This mechanism makes the Cavitron and CAVASOL HPBCDs and HPGCDs capable ...
