Excipients & Additives

Bulk Excipients & Additives

Excipients and additives are the materials that make a formula run on the line: flow agents and lubricants such as magnesium stearate and silicon dioxide, fillers and binders such as microcrystalline cellulose, maltodextrin and corn starch, acidulants such as citric, malic and tartaric acid, gums such as xanthan gum and gum arabic, and other additives such as glycerin. As a bulk excipient supplier, Omni Ingredients sells them wholesale by the kilogram, with pound and gram conversions available for quoting. Because excipients are quoted alongside your actives, a complete formula can go out in a single request. Items marked “In stock - US” ship from our domestic warehouse network; items marked “Made to order” are sourced for your order through vetted, cGMP-compliant manufacturing partners. Every lot is batch-numbered, with its certificate of analysis supplied with the shipment or on request.

What to specify in your quote request

Excipients are chosen for how they behave in your process, so specify them as precisely as the actives: the compendial standard your specification cites (for example USP), the particle size or mesh, the bulk density, and for materials such as microcrystalline cellulose or starch, the specific grade your process was validated on. For acids, name the form (L-, D- or DL-) and whether you need an anhydrous or coated grade. State any source requirement your label depends on, for example a vegetable source for magnesium stearate, and ask for the current lot's COA with the quote.
