Cosmetics OEM Instead of pouring ready-made contents into a bottle. For a project that can be delivered stably, business requirements must be translated into formula standards, packaging material standards, packaging documents, compliance materials, production plans and quality standards. Any node without written confirmation may become rework, delay or inventory later.
1. Requirements communication: first turn vague ideas into project briefings
At the beginning of the project, the target customer group, sales channel, country, category, capacity, price band, first batch quantity, efficacy direction, fragrance, color, texture, reference sample and time to market are confirmed. You can communicate if you have incomplete information, but at least determine the category, channel, price and quantity first.
Based on this, the factory determines the applicable equipment, mature formula resources, packaging material path, regulatory difficulty, minimum order quantity and time risk, and gives an itemized quotation.
2. Formula plan: fine-tuning or re-development of mature formulas
Mature formula fine-tuning is suitable for projects with tight time to market and clear budgets; reference sample benchmarking is suitable for existing experience goals; new development is suitable for brands with higher differentiation requirements and able to accept more testing cycles. All three models must clearly define raw materials, dosage forms, target skin feel and claim boundaries.
A recipe plan is not a list of ingredients. It also includes pH, viscosity, color, aroma, preservation, process, filling temperature and usage experience.
3. Sample Evaluation: Establishing Repeatable Sample Signing Standards
Each round of samples is labeled with version, date and adjustments. During the trial, the dosage, location, environment and evaluation time are fixed, and the appearance, smell, viscosity, extension, absorption, foam, rinse, color development, makeup or fragrance retention are recorded. The final sample shall be confirmed by both parties and retained.
Research shows that sensory evaluation is important for consumer acceptance of cosmetics, and instrumental testing can help quantify but cannot completely replace actual use evaluation. Signatures should ideally contain both subjective descriptions and measurable specifications.
4. Packaging material confirmation: Verify the contents and container together
Confirm bottles, cans, pumps, nozzles, caps, inner plugs, hoses, labels, color boxes, gift boxes, inner trays and outer boxes. Focus on testing the filling caliber, discharge volume, pump head rebound, sealing, leakage prevention, temperature resistance, drop, coding and assembly.
Stability studies emphasize the difference between product stability and container compatibility. Formulations may absorb to the plastic, affect color, or interact with seals, so all packaging materials cannot be purchased directly without sample testing.
5. Packaging documents and regulatory information: proofread before printing
The packaging documents at least check the product name, net content, full ingredients, usage methods, precautions, batch number or date expression, responsible party, address, country of origin and target language. Also confirm barcode, font size, layout position and process achievability.
Prepare formula, process, product specifications, inspection, safety assessment, filing or notification information according to the market. The United States, the European Union, the United Kingdom, Canada and China have different requirements and cannot be mechanically reproduced with one information package.
6. Production Scheduling: Once the raw materials and packaging materials are complete, the line will be locked
Confirm order quantity, loss, material arrival, formula version, sample signature, packaging documents and delivery date before production. After the materials enter the factory, quantity, appearance, specifications and necessary quality inspections are carried out. Unqualified materials should be isolated.
The normal reference time is 7-10 days for proofing and 15-30 days for large quantities. However, formula development, filing, customized bottle color, mold opening, electroplating, gift boxes and international transportation may all increase the lead time.
7. Mass production: key nodes must be traceable
The production process includes raw material procurement and weighing, preparation or emulsification, semi-finished product inspection, filling, sealing, inkjet coding, labeling, boxing and cartoning. The batch number should be associated with the raw material batch, production date, equipment, personnel, inspection and finished product destination.
ISO 22716 Covers the quality aspects of cosmetics production, control, storage and shipment, and provides a framework for factories to establish personnel, site, equipment, materials, production, deviation and complaint management.
8. Shipping inspection and delivery: not just checking the quantity
Before shipment, check the appearance, smell, color, filling volume, sealing, pump head, inkjet coding, label, color box, packing and quantity according to the signature and packaging documents. Review physical, chemical, microbiological or third-party testing agreed upon by the project when necessary.
When delivering, provide packing list, batch number information and agreed information, and keep samples of finished products. Cross-border projects also require confirmation of shipping marks, pallets, container specifications, trade terms and customs declaration information.
9. After-sales and repurchase: use real feedback to improve the next batch
Complaints, returns, pump head failure, leakage, skin feel and packaging damage will be recorded after launch and traced by batch number. Distinguish between occasional use problems, transportation problems and batch problems, and then decide on replenishment, rectification or recall measures.
Repurchase orders are not simply copies of old orders. Recheck regulations, labels, raw materials, packaging material colors and delivery dates, and evaluate whether any changes will affect filing, stability or consumer experience.
FAQ
Cosmetics OEM What is the first thing to confirm in the process?
First confirm the target customer group, channels, price range and product category, and then discuss the formula and packaging.
Who decides the formula and bottle first?
Both need to be evaluated in parallel, but bulk packaging material purchases should be made after formula, filling and compatibility are confirmed.
What should I write when signing a sample?
Record the sample number, formula version, color, fragrance, texture, packaging material and the date of confirmation by both parties.
Why does the delivery date change?
Any changes in raw materials, packaging materials, printing, testing, regulatory information and production schedules may affect delivery.
What does full shipment inspection mean?
The scope of full inspection needs to be defined in the contract. Appearance packaging can be inspected piece by piece, and physical, chemical and microbiological inspections are usually conducted on a batch-by-batch basis.
