Liquid Dosage Forms, From Water-Soluble Blends to Emulsions

Liquids are hard to keep stable: actives fall out of solution, oils separate, flavours drift and preservatives must hold the whole shelf life. ZOOMSHEAL runs dedicated liquid lines in our GMP-certified Guangzhou facility, where we manage solubility, emulsification, viscosity, taste masking and preservation together.

We produce kids multivitamin liquids, elderberry and echinacea syrups, alcohol-free tinctures, vitamin D3 and K2 drops, iron and zinc tonics and fish oil or algae oil emulsions. Fill volumes run from 10 mL dropper bottles to 500 mL syrups and 10-25 mL single-serve stick gels, with sugar-free, no-preservative and organic-ready options.

What Sets Our Liquid Supplement Production Apart

Water-Soluble, Oil-Soluble and Emulsified
We formulate syrups, oil-based drops and oil-in-water emulsions with food-grade emulsifiers and high-shear processing, so oil-soluble actives like D3, K2 and omega-3 stay dispersed and resist creaming for 18-24 months.
Suspension and Stability Technology
For insoluble minerals and botanicals we use suspension systems, controlled particle size and xanthan or cellulose gums to stop settling. Stability studies confirm potency, pH and appearance over 18-24 months.
Taste Masking and Mouthfeel
Liquid taste is decisive for repeat purchase, so we mask bitter actives with natural sweeteners, fruit flavours and acidity control, and tune viscosity for a clean mouthfeel tested in kids and adult panels.
Preservative Systems and Hot-Fill Options
We can use natural preservation with potassium sorbate and sodium benzoate, or run a preservative-free hot-fill process with acid control and aseptic filling. Every batch is challenge-tested for microbiological safety.

Our Liquid Supplement Contract Manufacturing Process

01
Consultation & Brief
We review your actives, dose, target market and preferred bottle, then recommend a liquid form, preservation system and fill volume that fit your volume and cost target.
02
Formula & Pilot Sample
Our team develops the base, tests solubility or emulsification and produces a pilot batch so you can review taste, colour, viscosity and clarity before approval.
03
Quotation & Approval
Once the sample is approved we lock the formula, confirm MOQ, bottle and cap, and issue a final quotation, specification and proforma invoice.
04
Production & Filling
Actives are dissolved, suspended or emulsified under controlled conditions, then filled into glass, dropper or stick packs with in-process fill-weight and pH checks.
05
Quality Control & Testing
Every batch is tested for active content, pH, density, microbial safety and seal integrity, and released only after the certificate of analysis is approved.
06
Packaging & Export Shipping
Bottles are capped, sealed, labelled and export-packed to your artwork, then documented for air, sea or express shipment to your destination.

Quality Control for Liquid Stability

A liquid supplement is only as good as its stability, so our quality programme focuses on solubility, homogeneity, pH and microbiological safety. Incoming actives are verified against their certificate of analysis, and each finished batch is tested for active content, pH, density, preservative level and microbial load.

The plant is GMP-certified in Guangzhou and works to FDA, NSF and cGMP standards, with HACCP controls across dissolution, emulsification, filling, capping and packing. Accelerated and real-time stability studies back the shelf life and the label claim on your finished liquid.

Liquid Supplement Manufacturing FAQ

What is the minimum order quantity for liquid supplements?+
Oral liquids, syrups, tinctures and emulsions start at 5,000 bottles, and liquid stick gels at 10,000 sachets. Bulk liquid concentrate starts at 25 kg. If you are testing a new SKU we can discuss a starter batch before you commit.
Can you make liquids under my own brand?+
Yes. We manufacture as a private label and OEM/ODM producer, so your brand is printed on the label, carton and certificate of analysis. You keep the finished product and the brand, and we provide the formula, bottle and packaging.
How long does liquid supplement production take?+
Allow 4 to 6 weeks after formula and artwork approval for liquids, syrups and drops, and 4 to 6 weeks for emulsions and elderberry syrups. Raw material sourcing, blending, filling, release testing and export packing are all included.
How do you keep oil and water based actives stable?+
Oil-soluble actives are emulsified with food-grade emulsifiers and high-shear mixing to a controlled droplet size, while insoluble minerals are suspended in a gum system. Accelerated and real-time stability tests confirm the emulsion does not separate for 18 to 24 months.
Can you make preservative-free liquids?+
Yes. We can run a preservative-free hot-fill process with acidity control, or use natural preservation with potassium sorbate and sodium benzoate. Both routes are challenge-tested to confirm microbiological safety across the shelf life.
Do you provide bottles, droppers and child-resistant caps?+
Yes. We supply glass and PET bottles, dropper bottles, measuring cups and child-resistant or tamper-evident caps, and our team can prepare label artwork, dielines and market-specific text so the product arrives retail-ready.
Can you help with shipping and customs documents?+
For liquid shipments we compile the commercial invoice, packing list, certificate of analysis, certificate of origin and health certificates where needed, then dispatch by air, sea or express. Liquids use leak-proof packing and carry the documents your market requires.
What payment terms do you offer?+
Liquid orders normally carry a 30% deposit at the outset and a 70% balance due before shipment, settled by T/T or another agreed method. Repeat customers may negotiate more flexible terms, and pricing is quoted in USD unless you request another currency.
