Ingredients and Formulation Conditions for Soft Gels
Soft Gels can encapsulate a wide range of oils and certain suspension-type liquid ingredients, making them one of the most established dosage forms for lipid-based nutrients.
Suitable ingredient types:
- Essential fatty acids such as deep-sea fish oil, algae DHA, GLA evening primrose oil, and borage oil.
- Phytonutrient oil blends including lutein oil, astaxanthin oil, and anthocyanin oil concentrates.
- Collagen peptide oil solutions, Coenzyme Q10, and botanical extracts.
- Fat-soluble vitamins such as Vitamin A, D, E, and K.
- Herbal oils and various multi-oil formulations.
Formulation conditions and limitations:
- Ingredients should have suitable fluidity and be compatible with an oil-based environment to ensure proper filling and sealing.
- For suspension-type formulas, uniformity and storage stability must be evaluated.
- Water activity should be controlled to prevent shell deformation or softening.
- Ingredients with high oxidation sensitivity should include antioxidant systems and appropriate packaging.
- Shell thickness and hardness can be adjusted for target consumers (e.g., seniors, children).
- Options include animal-based or plant-based shells depending on market needs.
Soft Gel-Specific Process Management and Three-Tier Quality Assurance
1) Tier One: Soft Gel Raw Materials and Process Control
The Soft Gel manufacturing process must strictly control oil stability, shell thickness, seal integrity, and weight uniformity. Gin Hwa has established a complete Soft Gel production line built to international food safety standards, enabling in-house completion of every stage from oil preparation and shell processing to sealing and forming.
Raw Material Identity Verification and Specification Testing
Verify the origin, specifications, and test reports of fish oil, algae oil, botanical oils, and various functional oil ingredients as the foundation for formulation design.
Oil Blending, Homogenization, and Stability Testing
Blend multiple oils and fat-soluble ingredients according to formulation requirements, then evaluate appearance, phase separation, and oxidation stability.
Uniformity Check for Suspension-Type Ingredients
Test the uniformity of oil-based systems containing suspended powders to prevent sedimentation or separation during storage, ensuring consistent content per capsule.
Gel Shell Cooking and Thickness Adjustment
Control shell cooking conditions and viscosity to fine-tune shell thickness and elasticity, balancing swallowability with structural integrity.
Fill Volume and Seal Integrity Testing
Precisely control fill volume and shell encapsulation, then assess seal strength and tightness to prevent leakage or rupture.
Weight Uniformity and Appearance Inspection
Perform batch inspections on weight variation, shape, surface gloss, and color to ensure a consistent visual impression and swallowing experience.
Packaging Format and Filling Design
Design filling volume, layout, and protection according to bottles, blisters, or aluminum pouches, aligned with channel display requirements.
Retention Samples and Light/Oxidation Testing
Conduct light exposure and oxidation stability assessments, combined with labeling, batch numbers, and production scheduling to build a fully traceable quality record.
2) Tier Two: International-Level Quality Standards
Gin Hwa’s Soft Gel production environment fully complies with international food safety standards. From raw material receiving to finished product shipment, every step follows standardized procedures, supporting domestic health supplement brands, medical channel brands, as well as cross-border OEM / ODM projects.
The Soft Gel production line is operated under a comprehensive food safety management system, including hazard analysis, critical control point monitoring, and documented records—ensuring every Soft Gel capsule has solid evidence of oil stability and hygienic safety.
3) Tier Three: External Audits and Government Inspections
The factory undergoes regular inspections by competent authorities. In case of any nonconformity, CAPA (Corrective and Preventive Actions), batch traceability, and product recall procedures are initiated in accordance with regulations, ensuring every Soft Gel batch meets food safety requirements before entering the market.

Soft Gel OEM FAQ
Q1｜What is the MOQ for Soft Gel OEM?
The MOQ for Soft Gel OEM depends on factors such as shell color (clear, amber, opaque, two-tone), printing requirements, and formula complexity. In most cases, we recommend starting with a launch batch for new products, then scaling up to mass production based on channel performance and sales results, allowing for flexible planning.
Q2｜What kinds of ingredients can be filled into Soft Gels?
Soft Gels are suitable for oils and fat-soluble ingredients, such as fish oil, algae oil, evening primrose oil, lutein oil, astaxanthin oil, fat-soluble vitamins A / D / E / K, botanical oils, and blended functional oils. For suspension-type formulas, suspension stability and long-term storage performance must be evaluated in advance.
Q3｜Will Soft Gels have fishy or oxidation odors? Can this be improved?
If oil-based ingredients are not properly protected, fishy or oxidized odors may occur. Gin Hwa designs antioxidant systems, shell colors, packaging formats, and storage conditions according to ingredient characteristics, combined with light exposure and oxidation stability tests, to help reduce off-flavor risk and extend overall product stability.
Q4｜How long does the Soft Gel OEM development process take?
The typical process includes: “Formula confirmation → Oil blending and stability evaluation → Soft Gel trial run → Appearance and weight adjustment → Packaging confirmation → Pilot run → Mass production.” A common development lead time is about 6–10 weeks, and the actual schedule will vary based on formula complexity and packaging customization.
Q5｜Can existing oil or powder formulas be converted directly into Soft Gels?
If you already have an oil-based formula or a formula that can be adapted to an oil-soluble system, it may be converted into Soft Gels after evaluation. Gin Hwa can assist with viscosity adjustment, antioxidant design, shell thickness, and capsule size, so that existing formulas better match Soft Gel manufacturing conditions and target channel requirements.
