Whether you are a startup beauty brand, an offline daily chemical chain store, or an established enterprise looking to expand into the hair care product line, choosing the right shampoo factory is the first critical step to product success. However, in actual cooperation, many people fall into “low-price traps”—for example, factories use industrial-grade surfactants instead of cosmetic-grade raw materials, causing scalp irritation; or “customization cuts”—the promised anti-hair loss formula actually contains only trace amounts of active ingredients; in worse cases, products are removed from the market by regulatory authorities because the factory lacks an SC Cosmetic Production License. Based on 12 years of experience in the daily chemical OEM industry and combined with over 30 brand cooperation cases, this article breaks down the 4 core capabilities of high-quality shampoo factories, 3 key guidelines to avoid cooperation pitfalls, and interprets the 2025 industry trends to help you avoid 90% of cooperation risks and quickly identify reliable OEM partners.
I. The 4 Core Capabilities of High-Quality Shampoo Factories: The Key to Determining Product Competitiveness
1. Raw Material Control: Eliminating “Hidden Risks” from the Source
The gap between high-quality factories and small workshops begins at the raw material stage. Regular shampoo factories establish a “dual traceability system”:
- Supplier Access: Only cooperate with enterprises holding cosmetic raw material filing certificates. For example, first-tier brands such as BASF (Germany) and Kao (Japan) are preferred for surfactants, and suppliers are required to provide a Certificate of Analysis (COA) for each batch of raw materials;
- Raw Material Storage and Testing: Raw material warehouses adopt zoned management (liquid raw materials are stored at a constant temperature of 25°C, and solid raw materials are protected from moisture). Before warehousing, raw materials must pass 3 tests in the factory laboratory—heavy metals (lead, mercury, arsenic), microorganisms (total bacterial count ≤ 1000 CFU/g), and active ingredient content (e.g., zinc pyrithione for anti-dandruff must meet 1.0%-1.5%).
In contrast, inferior factories often use unregistered “bulk raw materials” and even replace mild sodium laureth sulfate with detergent raw materials (sodium dodecylbenzene sulfonate), leading to excessive pH values of products (the normal pH range of shampoo is 5.5-6.5, which is close to the scalp environment). Long-term use can easily cause dandruff and itching.
2. Formula R&D: Not “Copying”, but “Customized Adaptation”
Reliable shampoo factories are equipped with independent laboratories, and their R&D teams have at least 5 years of industry experience. Their core capabilities are reflected in:
- Efficacy Customization: Ability to adjust formulas according to brand needs. For example, for oily scalps, the compound ratio of niacinamide (regulates sebum secretion) and zinc PCA (oil control + anti-inflammation) is increased; for sensitive scalps, sulfate-based surfactants are replaced with amino acid surfactants (sodium lauroyl glutamate), while panthenol (moisturizing) and allantoin (soothing) are added;
- Stability Testing: New formulas must undergo 45°C high-temperature and -15°C low-temperature cycle tests (72 hours each) to ensure no stratification or discoloration in different environments; a 6-month accelerated aging test is also required to verify that active ingredients do not degrade during the shelf life.
A customer once reported that a small factory “copied” a well-known brand’s anti-hair loss formula but failed to conduct stability testing, resulting in stratification of the product after 3 months of storage and rendering 100,000 bottles unsellable.
3. Production Technology: GMPC Standard is the “Baseline”, Not a “Bonus”
Regular shampoo factories must hold an SC Cosmetic Production License, and their production workshops must comply with GMPC (Good Manufacturing Practice for Cosmetics) standards. Specific reflections include:
- Workshop Cleanliness: The air cleanliness of the filling workshop reaches Class 10,000 (≤ 35,200 dust particles per cubic meter). Operators must go through 3 procedures—changing clothes, disinfection, and air shower—to avoid microbial contamination;
- Production Precision: Automatic filling equipment is used with an error ≤ ±0.5ml (e.g., for 500ml shampoo, the weight deviation of a single bottle does not exceed 0.5g), avoiding the problem of “different weights per bottle”;
- Sterilization Process: Emulsification tanks use steam sterilization (temperature ≥ 121°C for 30 minutes), and pipelines are rinsed with purified water 3 times after each use to prevent cross-contamination from residual raw materials.
Unqualified small factories, however, often produce in workshops converted from residential houses, relying on manual pouring for filling. The microbial over-standard rate is as high as 30%, and products easily trigger consumer complaints.
4. Testing System: “Factory Inspection” is Not Enough—”Full-Process Inspection” is Required
High-quality shampoo factories establish a “3-level testing mechanism” to ensure the qualification of each batch of products:
- Semi-finished Product Testing: After emulsification, test pH value, viscosity (using a rotational viscometer; normal shampoo viscosity is 3000-8000 mPa·s), and active ingredient content;
- Finished Product Sampling Testing: Randomly sample 10% of products from each batch and send them to third-party testing institutions (e.g., SGS, Pony Testing) for full-item testing, including heavy metals, microorganisms, and preservatives (e.g., methylisothiazolinone (MIT) content ≤ 0.01%);
- Sample Retention Management: Retain 2 samples of each batch of products in a constant temperature and humidity warehouse for a retention period of 6 months beyond the product’s shelf life. If quality problems occur, the cause can be traced.
In 2024, a brand failed to retain samples due to the factory’s negligence. After consumers complained about “scalp allergies”, the brand could not trace whether the problem was caused by raw materials or processes, and finally had to recall all products, resulting in a loss of over 800,000 yuan.
II. Must-See for Cooperating with Shampoo Factories: 3 Guidelines to Avoid Pitfalls (with Real Cases)
1. Pitfall Avoidance 1: Don’t Just Focus on “Quotes”—First Check the “Three Qualification Certificates”
Many people prioritize low-priced factories when cooperating, but ignore qualification verification, ultimately failing due to compliance issues. The correct approach is:
- Must-check 3 certificates: SC Cosmetic Production License (authenticity verifiable on the official website of the National Medical Products Administration), ISO 9001 Quality Management System Certification, and GMPC Certification;
- Be alert to “affiliated factories”: Some intermediaries use the qualifications of regular factories to accept orders but actually outsource production to small workshops. You can ask the factory to provide “live videos of the production workshop” or “production batch records of the past 3 months” to verify its actual production capacity.
Case: An e-commerce brand in 2023 chose a factory with a “quote 30% lower than the market price” for OEM without checking qualifications. After the products were launched, they were reported. An investigation revealed that the factory lacked an SC License and was engaged in “unlicensed production”. The brand was not only fined 50,000 yuan but also had all products confiscated.
2. Pitfall Avoidance 2: Conduct “Small-Batch Trial Production” First, Then Sign the “Bulk Order Contract”
Many brands directly sign bulk order contracts, but due to the factory’s “insufficient formula implementation capabilities”, the bulk products differ greatly from samples. The correct process is:
- Trial Production Quantity: For the first cooperation, it is recommended to conduct trial production of 500-1000 bottles to test the product’s usability (foam volume, rinsing difficulty), stability (observation after 1 month of storage), and efficacy (e.g., for anti-hair loss products, send to testing institutions to measure the proportion of telogen hair);
- Clarify “Difference Clauses” in the Contract: After passing the trial production, the active ingredient content deviation between bulk products and trial samples must be ≤ 5%. If not up to standard, the factory shall be responsible for rework or refund.
Case: An offline chain brand in 2024 collaborated with a factory to produce anti-dandruff shampoo. It placed an order for 50,000 bottles directly without trial production. After receiving the bulk products, it was found that the anti-dandruff effect was far worse than the sample. Testing showed that the zinc pyrithione content was only 0.3% (vs. 1.2% in the sample). Although the factory finally compensated, the brand missed the sales peak season, resulting in a loss of over 200,000 yuan.
3. Pitfall Avoidance 3: Clarify “Delivery Time and After-Sales Service” to Avoid “Disputes”
Delivery delays and after-sales evasion are common problems in cooperation, which must be clearly stated in the contract:
- Delivery Details: Specify the raw material arrival time, production cycle (the normal production cycle for 5,000 bottles of shampoo is 7-10 days), and logistics delivery time. If the factory delays, it shall compensate 0.5% of the payment per day;
- After-Sales Scope: If products have problems such as stratification, peculiar smell, or microbial over-standard within the shelf life, the factory must provide a solution (rework/replenishment/refund) within 7 days and bear the round-trip logistics costs.
A customer once failed to include after-sales clauses in the contract when cooperating with a factory. After the products had microbial over-standard, the factory refused to take responsibility on the grounds of “improper storage by the customer”, and the customer had to bear the cost of destroying 150,000 bottles of products by themselves.
III. 2025 Shampoo Factory Industry Trends: These 2 Types of Factories Will Become “Mainstream Choices”
1. Efficacious Shampoo Factories: 30% Demand Growth, R&D Capability as the Core
According to the 2025 China Cosmetic OEM Industry Report, the OEM demand for efficacious shampoos (anti-hair loss, oil control, repair) has increased by 30% compared with 2024. Factories with the following capabilities are more favored:
- Supported by “Efficacy Test Reports”: Ability to assist brands in conducting third-party efficacy tests, such as testing “the reduction rate of telogen hair proportion in 28 days” for anti-hair loss products and “the reduction rate of scalp sebum secretion in 48 hours” for oil-control products;
- Mastery of Patent Ingredients: For example, cooperating with raw material suppliers to develop exclusive ingredients (e.g., plant-based anti-hair loss complexes) or owning independently developed patented technologies (e.g., microcapsule encapsulation technology to extend the retention time of active ingredients).
2. Green Production Factories: Environmental Compliance as a “Mandatory Requirement”
With the tightening of national environmental requirements for the cosmetic industry, starting from 2025, factories with green production capabilities will be more competitive:
- Wastewater Treatment: Production wastewater must undergo “pretreatment + biochemical treatment” with COD (Chemical Oxygen Demand) ≤ 500 mg/L, meeting the Discharge Standard of Water Pollutants for Cosmetic Industry;
- Packaging Adaptation: Ability to provide degradable packaging (e.g., corn starch bottles, paper labels) or support “refillable” production to reduce plastic waste;
- Energy Conservation: Adopting solar power supply and waste heat recovery systems to reduce production energy consumption. Some leading factories have achieved the goal of “20% reduction in production energy consumption”.
Conclusion
Choosing a shampoo factory is essentially choosing a “product moat”—high-quality factories can help you avoid quality control risks, realize efficacy implementation, and even enhance product competitiveness through industry trends; while inferior factories will only trap you in a vicious cycle of “rework, recall, and fines”. It is recommended that before cooperation, you screen factories according to the steps of “Three Certificates for Qualification → Small-batch Trial Production → Full-process Testing”. If conditions permit, you can conduct on-site inspections of the factory’s laboratory, production workshop, and raw material warehouse to intuitively judge its strength.
