● About — who we are
Independent voice in a supplier-driven excipients world.
Most excipient information comes from sellers. ExcipientsAdvisor was founded by formulation scientists and QA auditors to give you neutral, data-backed guidance: what each excipient really does, where it fails, how to qualify alternatives, and how to stay inspection-ready.
✓
Functionality-first approach. We map every excipient to critical material attributes (CMAs) and critical quality attributes (CQAs) — flow, PSD, moisture, compactibility, disintegration.
✓
Regulatory memory. 120+ audits across IPEC, EXCiPACT, USP <1059>, Ph.Eur. monographs, FDA inactive ingredient database (IID) limits.
✓
Formulation rescue. Sticking, capping, poor dissolution, segregation? We diagnose root cause in days, not months.

Compliance radar
Stay ahead of monographs & inspectors
We track USP, Ph.Eur., FDA IID and IPEC updates so you don't have to. Short version: control variability, document rationale, qualify early.
| Topic | What changed 2024-2026 | Advisor take |
|---|---|---|
| USP <1059> Excipient Performance | Stronger emphasis on functionality-related characteristics (FRCs) | Add FRCs to specs: PSD, surface area, viscosity — not just ID + assay. |
| IPEC GDP + EXCiPACT | Annexes for co-processed excipients, data integrity | Ask for excipient composition disclosure + process description. |
| Nitrosamines (EMA/FDA) | Secondary amines in excipients under scrutiny (e.g., meglumine, DEA) | Risk assessment per product; test vulnerable lots, control nitrites. |
| Titanium dioxide (E171) | EU food ban spillover to pharma debates, alternatives rise | Qualify CaCO3 / starch-based opacifiers early for EU SKUs. |
| FDA IID & novel excipients | Pilot review program for novel excipients expanded | Use IID max levels as hard gate; novel = 12-18 months extra. |

How we test excipients
Loss on drying, PSD by laser diffraction, bulk/tapped density, Carr index, Hausner, flow through orifice, compactibility profiles, disintegration mapping, lubricant sensitivity ratio.
When to switch supplier?
If COA range > 15% of mean for critical FRCs, or if you see batch-to-batch hardness drift > 20N — start equivalence protocol before you face a shortage.
FAQ
Questions formulators ask us weekly
Short answers. For product-specific advice, use the contact form — we reply within 1 business day.
What is the most versatile filler for direct compression?
Microcrystalline cellulose PH102 for plasticity + spray-dried lactose for flow. For high drug load, consider co-processed MCC + colloidal SiO2 or lactose + starch composites to gain both compactibility and disintegration.
How much magnesium stearate is too much?
Typically 0.5–1.0% w/w. Above 1.5% or blending >5 min you risk hydrophobic film, lower dissolution and softer tablets. Use sodium stearyl fumarate if you need higher lubrication with less sensitivity.
Can I replace lactose due to intolerance concerns?
Yes — mannitol, MCC, dicalcium phosphate or starch-based fillers. Watch compactibility loss and moisture uptake. Re-validate dissolution and stability; mannitol gives cooling mouthfeel ideal for ODTs.
What documents do I need from excipient supplier?
COA, MSDS/SDS, TSE/BSE, allergen, residual solvents, elemental impurities risk assessment, nitrosamine questionnaire, manufacturing flow, change notification agreement, and EXCiPACT/IPEC GDP certificate if available.
Do you sell excipients?
No. We are 100% independent — no distribution, no commissions. That is why R&D and QA trust our equivalence verdicts and audit findings.
