Flavoring Excipients

Improve the desirable characteristics of taste, texture, and overall Palatability of your formulations with Spectrum's selection of pharmaceutical flavoring agents. Choose from our top sellers which include L-menthol, ethyl acetate, almond oil, and many more

Alkalizing Agents

Alkalizing agent ingredients which are useful when an alkaline environment for stability is required. Choose from ammonium carbonate, potassium hydroxide, sodium hydroxide, and many more.

Chelating Agents

Convert metal agents to a chemically inert form as-- well as other applications-- with Spectrum's selection of chelating agent Excipients, which include Edetic acid and Edetate Disodium. Also called sequestering agents, these Excipients can be used in some liquid pharmaceuticals as stabilizers to complex heavy metals that might promote instability.

Alcohol Denaturants

Discourage recreational consumption with Pharmaceutical alcohol denaturants, a commonly used ethanol with additives to render it undrinkable. Reagent alcohol denatured is also used in chemical labs as a polar protic solvent in organic synthesis.

Tablet Binders

Find a wide selection of pharmaceutical binders & tablet binders at Spectrum Chemical including Povidone K-30, also known as Polyvinylpyrrolidone or Polyvidone, which is a polymer and used as a binder in pharmaceutical tablets. Binder Excipients facilitate agglomeration of powder into granules in this process and might also affect granule properties such as flow, handling, strength, solubility, compaction, or drug release. In addition, you'll find Ethyl cellulose which is used in the pharmaceutical industry as a coating agent, flavoring fixative, tablet binder and filler

Diluent Excipients

Increase dosage form, volume, or weight of a pharmaceutical product, Because most dosages require only very small quantities of Active Pharmaceutical Ingredients (APIs), diluents often comprise a significant proportion of the dosage form. This means their physical and chemical properties are key variables in the manufacturing and performance of the product, and should be clearly understood and tightly controlled. Sorbitol, Kaolin, and Calcium Carbonate are just a few of our Diluent Excipients.

Glidant Excipients

Promote clump-free flow of granular mixtures with Spectrum's selection of Glidant Excipients. These Excipients reduce inter-particulate friction within a pharmaceutical formulation during the production of capsules.

Stiffening Agents

Stiffening agent Excipients are used primarily in topical preparations for increasing the preparation’s viscosity. Often stiffening agents find application as sustained-release carriers and to minimize sweating and bleeding of oil-wax blends.

Emulsifying Agents

Find a wide selection of pharmaceutical emulsifying agents that help an emulsion become more stable. Choose from our stock of popular emulsifying agent Excipients including sodium Lauryl sulfate, emulsifying wax, Polysorbate 80, and much more.

Wetting Agents

Find a wide range of pharmaceutical wetting agents at Spectrum Chemical used to create homogeneous dispersion of solid particles in a liquid vehicle. Choose from Sorbitan Monopalmitate, Poloxamer 407, and more.

Ointment Bases

Find a wide selection of ointment base Excipients at Spectrum Chemical which serve as vehicles for topical application of medicinal substances and as protective agents for skin. These Excipients are also liquids with a relatively high viscosity so that solids may be suspended as a stable mixture

Drug Delivery Vehicles

Take a look at Spectrum's large selection of drug delivery vehicle Excipients designed to modify drug release profiles for the benefit of improving product efficacy and safety. Besides oral & topical delivery, these Excipients' delivery can also include Transmucosal and inhalation routes.

Buffering Agents

Take a look at Spectrum's wide selection of buffering agent Excipients used to maintain the acidity of a solution. In addition, our stock of buffering agents prevent a rapid change in pH when acids or bases are added to the solution in order to assure the stability of the finished product.

Coating Agents

Coating agent Excipients which are natural or synthetic substances used to film coat the dosage carrier with a thin layer of polymeric material. Besides protecting the API from moisture, light or the acidic environment of the stomach, these agent Excipients mask the bitter taste of many active pharmaceutical ingredients.

Disintegrant Excipients

Spectrum carries a wide selection of Disintegrant Excipients designed to promote the breakup of the tablet into smaller fragments in an aqueous environment-- promoting a more rapid release of the drug substance

Humectant Excipients

While Humectant Excipients are most often found within the pharmaceutical formulation to control the moisture content of the topical pharmaceutical dosage form which increases the active ingredient solubility. The increased solubility increases the skin penetration which increases the active ingredient’s activity time.

Thickening Agents

Suspending agent Excipients help active pharmaceutical ingredients stay suspended in the formulation and prevent caking at the bottom of the container. One of the properties of a well-formulated suspension is that it can be easily re-suspended by the use of moderate agitation or shaking.

Lubricant Excipients

Lubricant Excipients decrease friction between the pharmaceutical formulations particles and the tableting equipment contact surfaces. Whether you require boundary, fluid-film or liquid lubricants, Spectrum specializes in providing the top lubricant Excipients but if you do not see the product, grade or form of the lubricant you require, just contact our Excipient chemical specialist. Get your products to market Safer, Sooner - Trust Your Ingredients!

Plasticizer Excipients

Spectrum offers a wide range of Plasticizer Excipients designed to modify the physical properties of a basic polymer. Plasticizer Excipients provide flexibility and permeability of the capsule film coating and are considered effective in retarding drug release in acid media. Choose from our wide selection below, including Propylene Glycol, glycerin, polyethylene Glycol, and much more.

Solvent Excipients

Solvent Excipients are used in ointments and other topical products, such as antibacterial creams and corticosteroids. These solvent Excipients are also used in the beginning of the process to manufacture the active ingredients. As the drug is being transformed into its final form, whether cream, lotion or liquid, solvents are used as a medium for blending material.

Solvents also are used to help the final product achieve the proper consistency. Spectrum specializes in providing the top drug solvents but if you do not see the product, grade or form of the drug solvent you require, just contact our Excipient chemical specialist. Get your products to market Safer, Sooner - Trust Your Ingredients!

Suppository Bases

Suppository base Excipients are used in the manufacture of suppositories (for rectal administration) and pessaries (for vaginal administration). They can be hydrophobic or Hydrophilic. Suppositories should melt at just below body temperature (37 C), which allows for erosion of the dosage form and release of the API. Hard fat suppository bases melt at approximately body temperature. Hydrophilic suppository bases also melt at body temperature, and typically also dissolve or disperse in aqueous media. This allows release to take place via a combination of erosion and dissolution.
