Recipe Formulation – Product & Process Design

This topic is part of the SG Systems Global regulatory & operations glossary.

Updated October 2025 • Formula Development, Scale‑Up & Digital Execution • R&D, Manufacturing, QA, Regulatory

Recipe formulation (also called product formulation or process design) is the end‑to‑end discipline of defining what a product is made of (materials, grades, assay) and how it is repeatedly made (sequence, parameters, controls) so that quality, cost, safety, and compliance are achieved by design. In digital operations, the “recipe” is expressed as effective‑dated master records (MBR/MMR) executed in a MES, trended in CPV, and kept inspection‑ready in an eBMR under Document Control with audit trails (Part 11/Annex 11).

“Great products are not inspected into existence—they’re formulated and controlled into existence.”

1) What “Recipe” Means in Regulated Manufacturing

A recipe is the operational manifestation of product design: a structured bill of materials (BOM) with grades and target amounts; processing steps with ranges and setpoints; instrumentation, timing, and interlocks; and the sampling and acceptance rules that make the outcome predictable. In practice, the recipe appears as an effective‑dated MBR/MMR issued under Document Control and executed in MES, where line‑clearance, user permissions, and e‑signatures (Part 11) enforce compliance and capture evidence into the eBMR.

2) Core Data Elements of a Robust Recipe

• Materials & grades: Approved item codes, specification links, and supplier equivalence rules (CoA, Incoming Inspection).
• Quantities & compensation: Target weights/volumes with loss factors, moisture/assay compensation, and scalable batch sizing.
• Sequencing & interlocks: The enforced order of operations with hold points, alarms, and stop‑logic.
• Parameters & ranges: Time, temperature, speed, pressure, vacuum, pH—each with setpoint, range, and control limits.
• Sampling & tests: IPC rules, methods, and acceptance criteria; links to validated analytics (MSA, HPLC).
• Labeling & claims: Artwork template references, variable data definitions, and scan‑back checks (labeling control, label verification).
• Allergen & hazard notes: Material hazard flags, priority allergen controls, and CCPs (HACCP/HAZOP).

3) Good Science: From Target Profile to Control Strategy

Start by defining what “good” looks like: target attributes (identity, potency/strength, purity, viscosity, texture, release profile), and the functional or regulatory claims on the label. Map the critical quality attributes (CQAs) to the critical material attributes (CMAs) and critical process parameters (CPPs). Use PFMEA to rank risks and choose controls. The recipe then encodes sampling, alarm limits (SPC), and (where appropriate) PAT sensors for real‑time assurance.

4) Ingredients, Units, and Compensation (Moisture & Assay)

Formulators must account for real‑world variability. Solids content, solvent loss, API assay, and moisture swing all distort delivered actives. Express targets as both as‑is and dry basis (or by assay), and teach the recipe to compute compensation. On the shop floor, gravimetric weighing blocks acceptance outside tolerance; MES records the compensated target and actuals into the eBMR and trends capability (Cp/Cpk).

5) Sequence, Timing, and Equipment Fit

Order matters: premix before addition; heat then hold; cool then filter. Encode mandatory preconditions (vessel ID, status, cleanline, calibration), minimum/maximum dwell times, and conditional branches (e.g., loop until moisture ≤ X%). Verify the recipe matches equipment capability—agitator speed envelopes, heating/cooling rates, and filtration area. Tie pre‑run checks to line‑clearance and asset status; block use for overdue calibration or cleaning (EM considerations where relevant).

6) Scale‑Up Without Surprises

Scaling a benchtop recipe to plant scale is not a linear multiplication. Geometry changes influence mixing, heat transfer, and mass transport. Document scale‑dependent rules (tip speed, Reynolds number, surface area‑to‑volume effects). Lock critical ramps and holds in the recipe and validate at the intended production scale via Process Validation and PPQ, then monitor in CPV. Scaling also exposes capacity and asset constraints—reflect them in planning (MRP) and in the job routing so OEE is optimized rather than eroded by bottlenecks.

7) Specifications, Methods, and Measurement Capability

Specifications must be defensible—anchored to product performance and process capability, not wishful thinking. Confirm that analytical methods are fit for purpose with MSA and that data flow into the record system under data integrity expectations. Integrate method references (e.g., HPLC) into the recipe so sampling, timing, and acceptance criteria are unambiguous and enforceable.

8) Allergen, Contamination, and Label‑Claim Design

Recipes influence cross‑contact risk and labeling. Flag allergenic inputs and require dedicated equipment or validated cleaning between allergen classes per your priority allergen control plan. Bake label‑claim rules into the recipe: variable data sources (lot/expiry), claim dependencies (e.g., solvent residuals below X), and scan‑backs at print/apply (label verification). Design with traceability in mind—lot genealogy (end‑to‑end genealogy) should be complete from goods receipt to finished goods release.

9) Materials Control: From Receiving to Kitting

Recipe integrity collapses if inputs are wrong. Ensure identity and status at goods receipt, apply risk‑based incoming inspection, and segregate by condition and allergen in the WMS (bin/zone rules via bin & zone topology). Pick/kit with barcoded verification (directed picking) and short‑circuit errors with barcode checks. If a material fails, capture the NCMR and escalate to MRB for disposition.

10) Executable Design: Turning Formulas into MBR/MMR

Author recipes as controlled, effective‑dated instructions. Each step should specify inputs, device connections, required scans, operator prompts, and acceptance logic. Attach approved templates, labels, and reports (labeling control). Validate e‑records and signatures against Part 11/Annex 11. During execution, the MES enforces IPC/SPC, collects evidence to the eBMR, and supports QA release by exception.

11) Validation and Proof That the Recipe Works

Design is only half; proof matters. Demonstrate the recipe’s intended use under Process Validation with representative lots and shifts; lock ranges and show reproducibility in PPQ. Build capability metrics (Cp/Cpk) and run CPV so drift is detected as OOT before it becomes OOS. Hold master evidence under Document Control with complete audit trails.

12) Managing Change Without Losing Control

Recipes evolve: new suppliers, new equipment, tighter limits. Route changes through MOC/Change Control, assess risk with PFMEA, and re‑validate as needed. Deviations during execution become Deviation/NC with corrective verification through CAPA. Periodic APR/PQR (APR | PQR) check that the design assumptions still hold and prompt recipe refreshes when the process or materials drift.

13) Supply, Cost, and Flow: Designing for Operations

A beautiful lab recipe can be a disaster in operations if it ignores sourcing, shelf life, or warehouse flow. Encode preferred alternates, lead times, and minimum stock in the item master; align formulations with MRP so supply is synchronized with demand. Design for kitting and for bin/zone topology that shortens travel. Where age matters, use FIFO/FEFO logic. Cost models should include yield, scrap, and rework pathways; controls should prevent unauthorized substitutions and silent rework. At pack, ensure artwork and claims tie back to recipe truth (labeling control).

14) Digital Evidence and Data Integrity

Every critical recipe attribute needs verifiable evidence: who mixed, what lot, what temperature, what alarms, what test results. Capture it contemporaneously into the eBMR with immutable audit trails, attributable signatures, and time‑sync across devices—core Data Integrity and Part 11/Annex 11 principles. This is the proof behind every release decision and recall‑readiness check.

15) Common Formulation Pitfalls & How to Avoid Them

• Paper recipes. Fix: encode as executable MBR with enforced scans, limits, and evidence capture in MES.
• No compensation for assay/moisture. Fix: compute compensated targets; tie to weighing blocks and capability trending (Cp/Cpk).
• Weak measurement. Fix: validate methods; perform MSA; avoid modeling noise.
• Allergen blind spots. Fix: classify and segregate; embed cleaning and label‑claim logic; verify at pack (label verification).
• Uncontrolled changes. Fix: route all edits via MOC/Change Control with re‑OQ/PPQ as needed.
• Supplier variability ignored. Fix: require CoA verification, trend lots, and escalate through NCMR/MRB.
• Label artwork drift. Fix: enforce artwork control and scan‑back every print.

16) How This Fits with V5 by SG Systems Global

V5 Solution Overview. The V5 platform is built for modern formulation control. Configuration is versioned, evidence is attributable, and cross‑module interlocks (identity, status, signatures) are testable and reportable—ideal for recipe execution and lifecycle improvement.

V5 MES. The V5 MES turns formulations into executable steps with enforced IPC/SPC, device integrations (scales, printers, sensors), allergen prompts, and pack‑level label verification, producing an inspection‑ready eBMR.

V5 QMS. Within the V5 QMS, recipe changes flow through MOC/Change Control, deviations escalate to CAPA, and validation packs (PV, PPQ, CPV) sit under unified Document Control.

V5 WMS. The V5 WMS enforces material identity, status, and segregation via bin/zone topology, FEFO/FIFO, directed picking, and allergen flags—so the right lot meets the right step, every time.

Bottom line: V5 turns formulation into a living, digital control system—your design intent becomes daily practice, and your production data fuels smarter, safer recipes.

17) FAQ

Q1. What is the difference between a formula, a recipe, and an MBR?
The formula is the quantitative composition and targets; the recipe adds sequence, parameters, and controls; the MBR is the controlled, effective‑dated execution document used in production and recorded into the eBMR.

Q2. How does PFMEA influence a recipe?
PFMEA ranks failure modes so the recipe can enforce the most important controls—sampling frequency, alarm limits, interlocks, and verification steps—where risk is highest.

Q3. Do we need PAT to formulate effectively?
Not always. You can run robust IPC with offline methods, but PAT moves measurements closer to the process, shrinking lag and enabling tighter control.

Q4. How are specifications chosen?
Based on product performance, regulatory expectations, analytical method capability (MSA), and demonstrated process capability (Cp/Cpk), then verified during validation and monitored in CPV.

Q5. How do we prevent labeling errors?
Control artwork in Document Control, generate labels from the recipe with versioned templates, and enforce scan‑back at print/apply through label verification.

Q6. What if an input lot doesn’t meet spec?
Quarantine and log an NCMR; route to MRB for disposition; update recipe or supplier controls via MOC if trends persist.

Q7. How do allergens affect formulation and execution?
Classify allergenic inputs in the recipe, segregate in the WMS, enforce cleaning/line clearance, and verify labels per priority allergen control.

Q8. Where is the proof that the recipe works?
In the validation dossier (PV/PPQ) and in routine CPV trends, all attributable in the eBMR with audit trails.
