Detox Liquid Manufacturer for Private Label Brands

Detox liquids sit between 1.0 and 1.4 specific gravity, which is where standard peristaltic pumps drift. We run inline gravimetric checkweighing on every fill head and reject outside ±1.5% of target weight. Two lines handle 30–500 ml glass and PET at a combined 12,000 bottles per shift; a third line covers 10–30 ml dropper and shot formats at 20,000 units per shift.

Hot fill runs to 92°C for preservative-free formulas. Cold fill with potassium sorbate and sodium benzoate covers the rest. Nitrogen purge is available for vitamin C and glutathione blends that oxidise within weeks. Every batch records fill weight, torque, and headspace. You receive the batch record as a PDF before release.

Common detox actives include milk thistle silymarin, dandelion root, artichoke extract, choline, N-acetylcysteine, and electrolytes. We source these as water-soluble powders or liquid concentrates. Where an ingredient is heat-sensitive, we move it to a cold-fill step after pasteurisation. This preserves 90–95% of input activity for most botanicals, verified by third-party assay on the finished batch.

Bases cover purified water, glycerin, apple juice concentrate, coconut water, and aloe vera. Sweetening uses stevia, monk fruit, or erythritol. Flavours are natural or nature-identical, and we hold EU and US-compliant allergen statements for each. pH is adjusted to 3.2–4.0 for shelf stability. Typical shelf life is 18–24 months unopened.

Our facility is GMP, ISO 22000, and HACCP certified. Halal certificates cover the lines used for those formulas. vegan claims are supported by supplier certificates and segregated handling. We are an FDA-registered facility, which allows US import without a prior notice gap. Every shipment carries a certificate of analysis, a safety data sheet, and a full ingredient breakdown with country of origin.

Shipping runs from Shenzhen and Hong Kong ports. FCL and LCL are both available. Typical transit is 18–25 days to US west coast, 28–35 days to Rotterdam, and 12–18 days to Jebel Ali. We handle export documentation including commercial invoice, packing list, and certificate of origin. Air freight is available for pilot quantities under 500 kg.

Every detox liquid batch is sampled at three points: incoming raw materials, the bulk liquid after compounding and the finished filled units. Identity testing by HPLC or UV-Vis confirms each active at the declared level, with potency assays run against a validated reference standard. Microbial testing covers total aerobic count, yeast and mould, E. coli and Salmonella, with results released before filling. Heavy metals are screened by ICP-MS against EU and US pharmacopoeial limits, and we retain the raw data for three years.

The certificate of analysis issued with each batch lists the product name, lot number, fill volume, active content, pH, specific gravity, microbial results and heavy metal values. It also states the test methods used and the release date. Retention samples of every lot are held for the shelf life plus six months, stored under the same conditions as the commercial stock. This allows us to re-test if a customer queries a batch after delivery.

Stability follows a real-time protocol at 25°C/60% RH and 30°C/65% RH, with accelerated conditions at 40°C/75% RH for three months. We test at 0, 1, 2, 3, 6, 12 and 24 months for appearance, pH, active potency and microbial count. For detox liquids with sensitive botanicals, we add a 40°C/75% RH pull at 1 and 3 months to flag early degradation. Results feed into the shelf life claim, typically 18 to 24 months for unopened bottles.

Water activity and preservative efficacy testing are run where the formulation uses a preservative system. For preservative-free detox liquids, we validate the process with a challenge test against USP <51> or EP 5.1.3, and the filling line runs under nitrogen blanketing where oxidation is a risk. Batch records are reviewed by a qualified person before release, and a copy of the release summary is available to the brand owner on request.

Detox liquids are filled into PET or glass bottles from 10 ml to 500 ml, with 30 ml and 60 ml the most common for shots and daily-dose formats. We also run stick packs and sachets for single-serve detox concentrates, with fill weights from 10 g to 30 g. Closures include tamper-evident screw caps, dropper tips for 30 ml formats and measuring cups for larger bottles. Label substrates can be paper, PP or clear film, applied by automatic labelling with a placement tolerance of ±1 mm.

For the US market, labels must carry the FDA dietary-supplement panel: supplement facts, serving size, amount per serving, percent daily value where applicable, and a complete ingredient list using the FDA names. We check that the label includes the statement of identity, net quantity, directions for use, and the manufacturer or distributor address. Allergen declarations follow FALCPA, and we flag any ingredient that requires a warning statement. For the EU, we cross-check the claims against the EU Register and the novel food catalogue.

Lot and expiry coding is applied by inkjet or laser on the bottle base or label edge, with the format agreed at artwork approval. Cartons are specified to a compression strength that suits the pallet pattern, typically 5-ply for export. We provide pallet configurations for 1,200 x 1,000 mm and 1,200 x 800 mm pallets, with stretch wrapping and edge boards. For Amazon sellers, we apply FNSKU labels and poly-bag the units where the retail packaging is not shipper-ready.

Retail-ready checks include barcode verification to GS1 standards, artwork proof against the approved file and a first-article inspection before the run starts. We do not print claims that are not supported by the formula or the documentation. If a brand wants to add a certification logo such as vegan or halal, the certificate must be in place before the artwork is released, because the logo cannot be added after the labels are printed.

Sampling starts with a brief and a target formula. We send a quotation within two working days, then produce a 500 ml lab sample for evaluation in 7 to 10 working days. If the sample needs adjustment, one revision round is included at no charge. Once the sample is approved in writing, we issue a proforma invoice and the production slot is booked. Pilot runs from 500 units are quoted separately and typically add 5 working days to the schedule.

Mass production runs 20 to 35 working days after artwork and sample approval, depending on bottle availability and whether the labels are printed locally or supplied by the brand. We hold safety stock of common bottles and closures, but custom moulds add 15 to 20 working days. The production window is confirmed in the proforma invoice, and we send a weekly progress update with photos at the filling and packing stages.

Shipping is by air or sea. Air freight from Guangdong to the US or EU takes 5 to 8 days door to door for orders under 500 kg, while sea freight takes 25 to 35 days port to port. We work on EXW, FOB Shenzhen or Hong Kong, and DDP for brands that want a landed-cost price. DDP includes customs clearance and duty, but the brand remains the importer of record for regulatory purposes. We recommend sea freight for orders above 1,000 kg.

Documents provided with each shipment include the commercial invoice, packing list, certificate of analysis, material safety data sheet, and a free-sale certificate where the destination country requires one. For plant-based detox liquids, a phytosanitary certificate can be arranged if the importing country asks for it. We also supply a certificate of origin on request. The brand owner is responsible for product registration and for confirming that the formula complies with local rules.
