1. What Is a Softgel Capsule?
A softgel (soft gelatin capsule) is a single-piece, hermetically sealed capsule made from gelatin or plant-based polymers, filled with liquid or semi-liquid active ingredients. Unlike two-piece hard capsules (HPMC or gelatin), softgels are formed, filled, and sealed in a single continuous operation.
Key distinguishing characteristics of softgels:
- One-piece construction — No seams or locking mechanisms; the capsule is formed around the fill material
- Liquid fill — Only compatible with liquid, suspension, or paste formulations
- Hermetic seal — Air-tight, oxygen-impermeable, and tamper-evident
- Custom shapes and colors — Round, oval, oblong, tube-shaped; single or two-tone color combinations
- Printing capability — Brand logos, dosage, or lot numbers can be printed directly on the shell
Softgels occupy a unique position in the supplement market: they command a premium price compared to tablets and hard capsules (typically 20-40% higher), yet consumers perceive them as higher quality and more effective due to faster absorption and easier swallowing.
2. Why Choose Softgel as a Delivery System?
Understanding the advantages and limitations of softgels helps brand owners decide whether this dosage form fits their product strategy.
Advantages
| Advantage | Explanation | Impact |
|---|---|---|
| Higher Bioavailability | The liquid fill is absorbed faster than solid dosage forms because it does not need to disintegrate in the digestive tract | Faster onset of action; lower dosage required for same effect |
| Precise, Consistent Dosage | Each capsule is filled by a precision pump with ±1% accuracy | Batch uniformity; regulatory compliance |
| Oxygen Protection | The sealed gelatin shell prevents oxygen contact with the fill | Extended shelf life for oxidation-sensitive ingredients (fish oil, CoQ10, astaxanthin, vitamin E) |
| Light Protection | Opaque gelatin formulations block UV light | Preserves light-sensitive ingredients (vitamin D, vitamin A, certain carotenoids) |
| Taste & Odor Masking | The shell completely separates the fill from taste receptors and olfactory senses | Better compliance for strong-tasting ingredients (fish oil, garlic, herbal extracts) |
| Ease of Swallowing | Smooth, lubricated surface; oval shape designed for swallowing | Higher consumer compliance, especially among elderly populations |
| Tamper Evidence | Cannot be opened and resealed without visible damage | Product integrity; consumer safety |
| Brand Differentiation | Available in custom shapes, sizes, and colors | Shelf stand-out; brand recognition |
Limitations
- Not suitable for dry or high-dose powders — The fill must remain liquid or semi-liquid
- Higher manufacturing cost — More complex process than tablets or hard capsules
- Higher MOQ — Typically 50,000-200,000 capsules minimum
- Temperature sensitivity — Softgels can deform or stick together in high heat
- Moisture sensitivity — Humidity control required during storage
- Limited ingredient compatibility — Water-sensitive ingredients need special handling; some ingredients interact with gelatin (aldehydes, reducing sugars)
3. Softgel Market Overview & Trends
The global softgel capsule market is projected to grow from approximately $8.2 billion in 2024 to $12.6 billion by 2032, at a CAGR of 5.5%. Key market drivers include:
- Aging population — Increased demand for joint health, heart health, and cognitive supplements in softgel format
- Fish oil and omega-3 growth — Softgels are the preferred delivery format for omega-3 supplements, a category growing at 8% annually
- Pet supplement expansion — Softgel-formulated pet supplements (fish oil, joint health) are a rapidly growing niche
- Novel ingredient delivery — Liposomal, self-emulsifying, and other enhanced delivery systems are increasingly available in softgel format
- Geographic expansion — Asia-Pacific is the fastest-growing region, driven by increasing disposable income and health awareness
For softgel manufacturers, these trends translate to growing demand for production capacity, especially from brands targeting the nutraceutical and cosmeceutical markets.
4. Raw Materials for Softgel Production
4.1 Shell Materials
The softgel shell is a complex formulation of several components:
| Component | Function | Typical Concentration |
|---|---|---|
| Gelatin | Structural polymer; provides strength, elasticity, and film-forming ability | 35-50% of dry shell weight |
| Plasticizer | Adds flexibility and prevents brittleness (glycerin, sorbitol, propylene glycol) | 15-30% |
| Water | Processing medium; facilitates gel formation | 20-40% (reduced during drying) |
| Opacifier | Provides opacity for light protection (titanium dioxide) | 0-2% |
| Colorant | Brand identity; product differentiation (FD&C dyes, natural pigments) | 0-0.5% |
| Preservative | Prevents microbial growth (methylparaben, propylparaben) | 0-0.2% |
Gelatin Types Used in Softgels:
- Type A (porcine/pork skin): Bloom strength 150-250; most cost-effective; common in non-religious-restricted markets
- Type B (bovine hide/bones): Bloom strength 150-280; preferred for halal and kosher products; higher cost
- Fish gelatin: Lower bloom strength (100-200); used for kosher/fish-based products; lower gel strength requires processing adjustments
Vegetarian/Plant-Based Alternatives: While the term "softgel" traditionally implies gelatin, plant-based alternatives exist:
- Starch-based: Modified starches with plasticizers; different processing parameters; less elastic than gelatin
- Carrageenan: Seaweed extract; combined with starch or cellulose for structure
- HPMC (hydroxypropyl methylcellulose): Requires different manufacturing approach; typically used for two-piece capsules
Note: Plant-based softgels require specialized equipment and are not available from all softgel manufacturers.
4.2 Fill Materials
The liquid fill for softgels can be categorized into three main types:
- Oil-based fills: The most common type. Includes fish oil, vegetable oils (MCT, flaxseed, borage), oil-soluble vitamins (A, D, E, K), CoQ10, astaxanthin, and essential oils. These are naturally compatible with gelatin shells because they do not extract water from the shell.
- Suspension fills: Oil-based suspensions of insoluble ingredients (e.g., calcium carbonate, herbal powders, probiotics in oil). Requires rigorous mixing and particle size control to prevent sedimentation.
- Water-in-oil emulsions: Used for ingredients that need water for dissolution (e.g., certain B vitamins, minerals). The water phase is emulsified into the oil phase to prevent water migration into the shell.
- Thixotropic gels: Semi-solid formulations that liquefy under shear stress during filling but regain structure after encapsulation.
Critical fill material properties:
- Viscosity: 100-20,000 cP (centipoise) — must flow under pressure but not leak from the die
- Water activity (aw): Below 0.6 to prevent water migration into the gelatin shell
- pH: 4.0-7.5 — extreme pH values degrade gelatin
- Particle size (for suspensions): Below 100 mesh (149 microns) to prevent nozzle clogging
5. The Complete Softgel Manufacturing Process
The softgel manufacturing process consists of seven main stages. Each stage requires precise control of multiple parameters for consistent, high-quality output.
Stage 1: Gelatin Mass Preparation
Equipment: Stainless steel jacketed tanks with vacuum deaeration, temperature-controlled heating, and high-shear mixing
Process steps:
- Weighing: Gelatin, plasticizer, water, and additives are weighed according to the master batch formula
- Hydration: Gelatin is allowed to hydrate in water for 30-60 minutes at room temperature to swell the particles
- Heating and Dissolution: The mixture is heated to 60-70°C with gentle agitation until all gelatin is fully dissolved (typically 60-120 minutes)
- Addition of Additives: Colorants, opacifiers, and preservatives are added in solution form and mixed thoroughly
- Deaeration: The molten gelatin mass is subjected to vacuum (typically 25-30 inHg) for 30-60 minutes to remove all dissolved and entrained air. Air bubbles in the shell cause weak spots, visual defects, and potential leakers.
- Filtration: The finished gelatin mass is filtered through 100-200 mesh screens to remove any undissolved particles.
- Hold: The gelatin mass is held at 55-65°C until ready for use. Maximum hold time is typically 24-48 hours before quality degrades.
Critical parameters:
- Viscosity: 10,000-30,000 cP at 60°C (measured by Brookfield viscometer)
- Moisture content: 30-40% (before drying)
- pH: 5.0-6.5 (gelatin's isoelectric point affects gel strength)
Stage 2: Fill Preparation
Equipment: Stainless steel mixing tanks with high-shear homogenizers, heating jackets (for oil-based fills), and vacuum deaeration
Process steps:
- Weighing: All fill ingredients are weighed per the master formula
- Mixing and Homogenization: Ingredients are blended at controlled temperatures. For suspensions, high-shear homogenization ensures even particle distribution.
- Deaeration: Vacuum is applied to remove air bubbles that would create fill weight inconsistencies
- Filtration: The fill is passed through screens (typically 60-100 mesh) to remove agglomerates or impurities
- Hold and Transfer: The fill is transferred to the encapsulation machine through heated hoses and held at the required temperature
Stage 3: Encapsulation (Rotary Die Process)
The rotary die encapsulation method is the industry standard, accounting for over 95% of commercial softgel manufacturing. This process was invented in 1933 by Robert P. Scherer and has been refined continually since then.
Equipment: Rotary die encapsulation machine (RDM), consisting of:
- Two gelatin casting boxes with adjustable knife assemblies
- Two chilled rotating drums (casting drums)
- Gelatin ribbon guides and lubrication rollers
- Two rotating die rolls with capsule-shaped cavities
- Fill metering pump system (piston or gear pump)
- Thermostatically controlled wedge
- Discharge conveyor
Detailed process flow:
-
Gelatin Ribbon Casting: Molten gelatin from the hold tank flows into a heated casting box. The box has an adjustable slot (knife gap) at the bottom, typically set to 0.020-0.045 inches (0.5-1.1 mm). Gelatin flows through this slot onto a chilled rotating drum (8-16°C). As the drum rotates, the gelatin solidifies into a continuous ribbon of uniform thickness. The ribbon is peeled off the drum and lightly lubricated with mineral oil to prevent sticking during die roll contact.
-
Ribbon Transport: Two ribbons — one from each casting drum — are fed between the matching die rolls. Tension rollers maintain uniform ribbon tension. Gelatin ribbon speed must be precisely synchronized with die roll rotation speed.
-
Die Roll Operation: Two die rolls, each containing capsule-shaped cavities, rotate in opposite directions at identical speeds (typically 3-15 RPM depending on capsule size and machine type). The cavities on each die roll align precisely with their counterparts on the opposite roll. As the ribbons enter between the closing die rolls, the dies press the outer edges together, forming a continuous series of interconnected capsule pockets.
-
Filling: As the die rolls close, a wedge (heated to 37-40°C) is positioned between the two ribbons, just ahead of the die closing point. A fill pump — typically a multi-piston metering pump synchronized with the die roll rotation — injects the precise volume of liquid fill through nozzles in the wedge into each capsule pocket as it forms. The fill volume is adjustable from 0.1 mL to over 1 mL depending on capsule size.
-
Sealing: Immediately after filling, the die rolls complete their rotation, pressing the two gelatin ribbons together around the filled pocket. The heat from the wedge and pressure from the dies creates a hermetic seal. The seal temperature (typically 37-42°C) and pressure must be precisely balanced — too low results in leakers, too high causes gelatin degradation.
-
Capsule Ejection: The formed capsules remain in the die roll cavities as they rotate past the bottom dead center, where they drop onto a discharge conveyor. Any residual gelatin web (the ribbon material between capsules) is removed as scrap.
Encapsulation machine throughput:
- Small machines (lab scale): 10,000-30,000 capsules/hour
- Mid-range production: 30,000-80,000 capsules/hour
- High-capacity production: 80,000-200,000+ capsules/hour
- Typical die roll sizes: #5 to #30 oval (3 to 30 minims fill volume)
Stage 4: Tumble Drying (Initial Drying)
Freshly encapsulated softgels are approximately 30-40% moisture by weight and too soft for handling. Immediate drying is essential.
Equipment: Perforated rotating tumble dryers with temperature and humidity control
Process:
- Capsules are gently tumbled in the dryer for 15-45 minutes
- Controlled airflow at 20-25°C, 30-40% RH removes surface moisture
- A light dusting of lubricant (typically a small amount of mineral oil or silicon dioxide) prevents sticking during subsequent tray drying
Stage 5: Tray Drying
Equipment: Drying tunnels or racks with temperature and humidity control; perforated trays (stainless steel or food-grade plastic)
Process:
- Capsules are spread in single layers on drying trays (typically 3-5 kg per tray for capsule size #20 oval)
- Trays are loaded into drying tunnels or rolling racks
- Drying conditions: 20-25°C, 30-40% RH, with continuous air circulation
- Drying duration: 24-72 hours depending on capsule size, shell thickness, and fill properties
- Critical: Capsules must be turned or rotated at regular intervals (every 2-4 hours during the first 12 hours) to ensure uniform moisture removal and prevent flat spots
- Target final moisture content: 6-10% by weight
Drying curve monitoring: Weight loss is tracked at regular intervals. A typical drying curve shows rapid moisture loss in the first 8-12 hours, followed by a gradual approach to equilibrium. Drying is complete when the weight loss rate falls below 0.1% per hour.
Stage 6: Inspection and Sorting
After drying, every capsule undergoes inspection before packaging. Softgel contract manufacturers typically employ a multi-tier QC process:
Level 1 — Automated Optical Inspection:
- High-speed vision systems inspect 100% of capsules at rates up to 60,000 capsules per hour per machine
- Defects detected: dents, cracks, surface contamination, seal imperfections, shape deformities, color variation, incomplete filling, leakers
- Rejection criteria are set during process validation; typical reject rate for well-controlled production is 0.1-0.5%
- Rejected capsules are diverted by air jet
Level 2 — Manual Visual Inspection:
- Trained operators inspect capsules on illuminated inspection belts
- Sampling frequency: Typically 10-30% of production, or as defined by AQL (Acceptable Quality Level) sampling plans
- Operator training and certification required per cGMP guidelines
Level 3 — QC Laboratory Testing:
- Weight check: Average fill weight ±1% of target; individual weights ±2% (per USP <698> for content uniformity)
- Disintegration: Must disintegrate within 30 minutes in simulated gastric fluid (per USP <701>)
- Shell moisture: 6-10% by loss-on-drying method
- Hardness/tensile strength: Measured by texture analyzer
- Seal integrity: Visual crack test under pressure; optional dye penetration test
Stage 7: Polishing, Coating, and Printing (Optional)
Polishing:
- Capsules are gently washed with ethanol or isopropyl alcohol in a perforated rotating drum to remove surface oil residue
- Dried with warm air (30-35°C) for 15-30 minutes
- Optional: Application of a thin wax coating (beeswax, carnauba wax) for gloss and moisture protection
Printing:
- Pharmaceutical-grade edible ink used for capsule printing
- Text can include brand name, logo, dosage strength, product code, lot number
- Printing methods: offset printing, inkjet printing
- Must pass print adhesion testing (rub test, solvent resistance)
Functional Coating:
- Enteric coating: Acid-resistant coating that dissolves in the small intestine (for sensitive ingredients or reduced stomach irritation)
- Delayed-release coating: Time-dependent release profile
- Note: Only specialized softgel manufacturers offer coating capabilities
Stage 8: Packaging
Bottling:
- HDPE bottles with child-resistant caps (CRC), induction-sealed
- Desiccant packs (silica gel) or desiccant caps for moisture control
- Cotton packing reduces capsule movement during shipping
- Typical bottle sizes: 30, 60, 90, 120, 180 count
Blister Packaging:
- Push-through aluminum foil or child-resistant blister
- PVC, PVDC, or Aclar (cold-form) blister materials depending on moisture barrier requirements
- Individual dose identification, ideal for clinical or premium products
Bulk Packaging:
- Multi-layer foil bags (5-25 kg) with oxygen absorbers
- FDA-approved HDPE pails (10-50 kg) for contract manufacturing shipments
Labeling and Coding:
- Each package receives a product label with required regulatory information
- Lot number and expiration date applied by inkjet or thermal transfer
- Case labels with barcode (UPC, GTIN) for supply chain tracking
- Serialization (DSCSA compliance) for pharmaceutical-grade products

13. Frequently Asked Questions
How long does softgel manufacturing take?
Standard lead time: 4-6 weeks from formulation approval to finished product. Custom formulations require an additional 2-4 weeks for R&D and pilot batch production. Stability testing (if required before market launch) adds 6-12 months for real-time data, though accelerated testing (1-3 months) is commonly used for initial market entry.
Are softgels better than tablets?
Neither is universally "better." Softgels offer superior bioavailability for oil-based ingredients, precise dosage, and oxygen protection. Tablets offer lower cost, higher dosage capacity per unit, and longer shelf life. Choose softgels when your active ingredient is oil-soluble, oxidation-sensitive, or requires enhanced absorption. Choose tablets for high-dose, water-soluble, or cost-sensitive formulations.
Can softgels be made vegetarian?
Yes, but with limitations. Plant-based softgels use modified starches, carrageenan, or seaweed extracts. However, they require different processing parameters, specialized equipment, and not all softgel manufacturers offer this capability. The texture and stability of plant-based softgels differ from traditional gelatin capsules.
What is the shelf life of softgel supplements?
24-36 months under proper storage conditions (15-25°C, below 45% relative humidity, away from direct sunlight). Heat (above 40°C) causes softening and sticking. High humidity softens the shell. Freezing can cause shell cracking due to fill expansion.
What is the minimum order for private label softgels?
MOQs typically range from 50,000 to 200,000 capsules per SKU, depending on capsule size, formulation complexity, and packaging requirements. Contact us for your specific needs.
How do I verify a softgel manufacturer's quality?
Request: (1) Certificates of Analysis for past batches, (2) Current certification documents (GMP, ISO, NSF), (3) Audit reports or schedule a facility visit, (4) Product samples from a pilot batch, (5) Client references, (6) Stability study reports.
What fill ingredients are compatible with softgels?
Compatible: Oil-soluble vitamins, fish oils, herbal oils, CoQ10, astaxanthin, vitamin E, essential fatty acids, and suspensions of certain powders in oil. Incompatible: High-water-content ingredients (aw >0.6), strong acids (pH <4), strong bases (pH >7.5), aldehydes and reducing sugars that crosslink gelatin.
Do softgels need refrigeration?
Most do not. Store at controlled room temperature (20-25°C). Refrigeration may benefit certain heat-sensitive fills (like probiotics in oil) but risks shell hardening and cracking from temperature fluctuations.
How are softgels shipped?
In HDPE bottles with induction seals and desiccant, packed in corrugated shipping cases. Temperature-controlled shipping is available for temperature-sensitive formulations.
What is the softgel capsule size numbering system?
Softgel sizes are measured in "minims" (1 minim = 0.0616 mL) and designated by size number (e.g., #5, #10, #15, #20, #30). Larger numbers indicate larger fill volumes. Most softgel machines can produce sizes from #5 (0.1 mL) to #30+ (0.6 mL+).
