YJOYJOY develops and manufactures custom car care chemicals for private label brands, distributors and professional detailing businesses. From our factory and formulation laboratory, we handle in-house formulation, sample development, formula adjustment, private label manufacturing, packaging and bulk production — taking your product from brief to shelf.
YJOYJOY develops and manufactures custom car care chemicals in our own factory and formulation laboratory. From the first concept to bulk production, the liquid is built, tested and filled under one roof through in-house formulation and R&D.
Our formulation team develops or adjusts formulas to your target performance, market positioning and product requirements.
Our laboratory prepares samples, runs performance testing and compares formula variants so you can evaluate before committing.
We evaluate raw materials and ingredient systems for performance, stability and cost, then select the combination that fits your spec.
After sample approval, our production team prepares the batch, sets the process and aligns packaging and filling for your order.
Production and quality control follow the confirmed sample and specifications, so each batch matches what you approved.
Our factory supports private label and OEM filling, bottling and kit assembly, then handles documentation and shipping.
We manufacture car care chemicals for private label and OEM projects. From concept and formula to sample, testing, adjustment, packaging, production, QC and shipping, our factory and laboratory keep your liquid product under one accountable team.
We focus on the liquid product itself — the formula, the feel, the performance and the package. Below are the liquid categories we regularly develop and customize for private label and custom projects. (Hardware and tools are handled separately under our product ranges.)
Product names above reflect liquid formulations we have experience handling. We customize the formula and specification of these and similar liquid products per your brief.
Use a proven existing formulation and apply your brand, bottle and label. Lowest development effort and typically the lowest minimum order quantity.
Best when: you need speed, a known performance profile, or a first private-label line.
Start from an existing base and adjust fragrance, pH, concentration, color or foam to better match your brand and market, without building a formula from zero.
Best when: you want differentiation with a shorter, lower-risk development cycle.
Our laboratory can develop or adjust formulations according to the buyer's target performance, market positioning and product requirements. The finalized specification is documented and held as your project — we do not resell your custom formula to other brands. Development follows sample, testing, feedback, revision and final approval.
Best when: you need a unique product, a proprietary specification, or a clear point of difference.
These are the levers you control when developing or modifying a liquid car care product with our laboratory. We can develop or adjust formulas based on buyer requirements — covering cleaning strength, concentration, pH, foam level, fragrance, color, viscosity, finish and hydrophobic performance — though feasibility depends on the product type and formulation.
| Parameter | What you can specify | Why it matters |
|---|---|---|
| Viscosity & consistency | Thin spray to gel | Application method and feel |
| pH level | pH-neutral to alkaline | Surface safety and use frequency |
| Concentration / dilution | Ready-to-use to high-concentrate | Value, shipping weight and cost |
| Fragrance | Scent profile & intensity, or unscented | Brand identity and user experience |
| Color & clarity | Tint, clear or opaque | Shelf recognition |
| Active ingredient system | Surfactants, protectants, ceramics | Performance target |
| Foam profile | Low to high foam | Foam cannon and wash compatibility |
| Bottle size & shape | 250 ml to 5 L, standard or custom | Retail format and MOQ per size |
| Cap / dispenser | Trigger, pump, flip, foamer | Function and usage |
| Label & artwork | Your brand, multilingual | Market and compliance |
A structured path from your brief to a finished, branded liquid product. Timings below are typical and confirmed per project.
You share performance goals, target market and any reference product.
We assess the route — stock, modified or custom — and any constraints.
A transparent quote with MOQ, lead time and documentation included.
A first sample is developed to your specification for evaluation.
Samples are typically shipped within 7–10 business days.
You test and send adjustment notes; up to a few rounds are typical.
The finalized specification is documented and approved by you.
Label proof, bottle and cap confirmation before production.
Pre-production sample approval, then bulk run, QC and shipping.
Your formula — custom or stock — filled into the bottle size and shape you choose, from retail sizes to larger formats.
Trigger, pump, flip-top or foam-spray heads matched to how the product is used, with samples available for confirmation.
Your brand, colors and multilingual copy. We provide proofs before print so the finished pack matches your positioning.
Combine several liquid SKUs or pair them with tools into a branded kit or bundle for a stronger retail offer.
Packaging and artwork are confirmed with you before bulk production begins, reducing rework and surprises.
Formula, bottling, packaging and shipping coordinated through a single contact rather than several vendors.
We are a sourcing and private-label partner, not a certification body. We help you assemble the documentation needed to ship and sell, and we advise on destination-market expectations — but final regulatory approval and certification remain the responsibility of the importer and local authorities. We confirm specifics per product and market in your quote.
Most car care liquids are not classified as dangerous goods and move by standard sea, air or express freight, including LCL consolidation to keep smaller orders economical.
Some concentrates or specific compositions may be classified as dangerous goods. We assess each formula and advise on correct classification, UN-spec packaging where needed, and carrier routing — so you are not surprised at the port.
Classification is determined per formula and destination; we confirm the shipping basis during project scoping, not as a blanket claim.
The more detail you share up front, the more accurate our sample and quote will be.
Brands wanting a differentiated liquid line under their own name.
Buyers building a sourced product range with stable supply.
Multi-location operators wanting a house brand of liquids.
Sellers upgrading from generic listings to a branded line.
Brands expanding from tools into liquid consumables.
Teams entering car care and needing a ready development path.
Formula, bottling, packaging, docs and shipping under one accountable partner.

Share your product idea, target market and specs. The more detail you provide, the more accurate our sample plan and quote will be. Fields marked * are required.
We will reply with a quote and sample plan within one business day (24 hours). For urgent matters, please call +8618260926700 or contact us via WhatsApp.
