Sunscreen OEM, not just an ordinary facial cream plus one SPF numbers

1. First give a conclusion: what does this question really determine?

The core selling point of sunscreen is measurable photoprotective properties, and different markets may place it on different regulatory pathways. The type of filter in the formula, dispersion, film formation, usage amount and light stability will all affect the results, so the formula, testing and filing process of ordinary facial creams cannot be directly applied.

This article does not simplify why sunscreen cannot be manufactured as ordinary face creams into a single number or empirical slogan. The project should clearly describe the product definition, target market, sample version, acceptance criteria and responsible person, and then use records to verify each step.

• Target markets first: China, the European Union, the United States and other paths and permitted filters are not exactly the same
• Protection goals:SPF,UVA, water resistance or other expressions require corresponding methods and evidence
• Dosage form and coating: lotion, cream, spray, and stick will affect the formation of the film layer
• Filter system: organic, inorganic or compound system involving dispersion and light stability
• Skin feel and dosage: Whether consumers are willing to use the test dosage will affect product strategy

2. Establish a decision matrix: answer these variables first

The project meeting should confirm item by item: 1. Target market first: China, the EU, the United States and other paths and allowed filters are not exactly the same; 2. Protection objectives:SPF,UVA, water resistance or other expressions require corresponding methods and evidence; 3. Dosage form and coating: emulsion, cream, spray, and stick will affect the formation of the film layer; 4. Filter system: organic, inorganic or compound systems involve dispersion and light stability; 5. Skin feel and dosage: whether consumers are willing to use the test dosage will affect the product strategy. Changes in any of these variables may trigger recalculation of formulas, packaging materials, quotations, tests, labels or delivery dates.

It is recommended that brands divide each variable into four states: "frozen, pending verification, replaceable, and irreplaceable". Unfrozen matters are entered into the risk list, and the decision date and approver are marked to avoid repetition of oral opinions after proofing.

3. Executable process: from requirements to frozen version

The recommended process is: 1. First freeze the country of sale, product attributes and intended use claims; 2. Screen the allowed filters and usage conditions according to the target market; 3. Carry out small trials of formula, dispersion/emulsification, light stability and film formation optimization; 4. Complete stability, packaging materials, microorganisms and necessary safety evaluations; 5. Carry out according to the target market method.SPF,UVA and water resistance and other tests; 6. Complete labeling, registration filing or drug monograph path information based on the final report. Each step should have inputs, outputs, completion conditions, and a person responsible for the next step.

The key to the process is not that more forms are better, but that samples, formulas, packaging materials, tests and labels use the same version number. Any sample that cannot be traced back to specific raw materials, processes and packaging should not be directly used as a basis for mass production.

• First freeze the country of sale, product attributes and intended claims.
• Screen allowed filters and conditions of use based on target market
• Conduct formulation pilot testing, dispersion/emulsification, light stabilization and film formation optimization
• Complete stability, packaging materials, microbiological and necessary safety evaluations
• Develop according to target market approach SPF,UVA and water resistance tests
• Complete labeling, registration filing or drug monograph path information based on the final report

4. Evidence Map: Which documents can support the judgment?

It is recommended to establish an evidence index, which at least includes: 1. Final formula and filter specifications, sources and batch records; 2. Under applicable methods SPF,UVA Or water resistance test report; 3. Stability, light stability, microbial and packaging material compatibility information; 4. Checklist of permitted filters and labeling requirements in the target market; 5. Corresponding records of production batches and test sample versions. The evidence needs to indicate the source, date, version, applicable products, applicable markets and custodian.

Supplier statements, laboratory reports, regulatory texts, and internal records have varying probative powers. When citing data, the conclusion should be limited to its sample, method and scope of application. Raw material data should not be directly extrapolated to all finished product conclusions.

• Final formulation and filter specifications, sources and batch records
• under the applicable method SPF,UVA Or water resistance test report
• Stability, photostability, microbial and packaging material compatibility data
• Target Market Permitted Filters and Labeling Requirements Checklist
• Correspondence records between production batches and test sample versions

5. Cost,MOQ How should it be separated from the cycle?

The quotation and scheduling should at least consider: 1. Filter raw materials, dispersion equipment and process control will increase development costs; 2. Efficacy testing costs are affected by projects, laboratories, samples and failed retests; 3. Multi-market shared formulas may increase development rounds due to differences in filter lists and labels; 4. Colored, spray, stick and high-power sunscreen usually have additional technical difficulties; 5. Packaging material barrier, discharging and temperature resistance requirements will also change costs. The same "unit price" may include different service boundaries and must therefore be compared using the same quantity, quality standards, data requirements and delivery location.

It is recommended to divide the total cost into one-time development fee, unit variable cost, testing compliance fee, residual material loss preparation, logistics warehousing and risk reserve; divide the cycle into demand freezing, proofing, testing, packaging materials, production scheduling, inspection and delivery, and indicate the starting conditions respectively.

• Filter raw materials, dispersion equipment and process controls increase development costs
• Efficacy testing costs are affected by project, laboratory, sample and failed retesting
• Formulas shared across multiple markets may increase development rounds due to differences in filter lists and labels.
• Tinted, spray, stick and high power sunscreens often have additional technical difficulties
• Packaging material barrier, discharge and temperature resistance requirements will also change costs

6. Quality control: converting from sample indicators to mass production standards

Quality control cannot just say "consistent with the sample". Measurable indicators should be written into specifications, and color, aroma, skin feel and appearance should be managed through standard samples, limit samples, controlled light sources or agreed methods, and first article, inspection, finished product inspection and retention samples should be set up.

Records directly related to this topic include: 1. Market access and filter list verification; 2. Formula, process, and test sample chain; 3.SPF/UVA/ Water resistance and original laboratory report; 4. Stability, packaging material and microbiological information; 5. Label claim approval and change records. Sampling, re-inspection, deviation and release authority must also be clear to ensure that mass production batches can answer "who released when and based on what evidence".

• Market access and filter list verification
• Formula, process, test sample version chain
• SPF/UVA/Water resistance and original laboratory report
• Stability, packaging materials and microbiological data
• Label claim approval and change logging

7. Compliance and target market: Don’t regard a report as a global passport

The judgment of the target market should cover: 1. Chinese sunscreen is a special cosmetic and needs to be registered and evaluated according to applicable requirements; 2. The EU is managed according to cosmetics regulations, but filters, labels and safety assessments need to meet local requirements; 3. American sunscreen belongs to the OTC drug route, and the M020 monograph and related requirements need to be checked. Regulations, system certification, raw material documentation, product testing and market registration solve different problems respectively and cannot be lumped together.

Brands, responsible entities, factories, raw material suppliers and third-party laboratories have different roles. Factories can provide manufacturing and quality documents, but specific product labeling, claims, and marketing responsibilities still need to be independently verified by sales market.

• Sunscreen in China is a special cosmetic and needs to be registered and evaluated according to applicable requirements.
• The EU is managed according to cosmetics regulations, but filters, labels and safety assessments need to meet local requirements.
• Sunscreen in the United States belongs to the OTC drug route, and the M020 monograph and related requirements need to be checked.

8. The most common failure modes and key points to avoid pitfalls

The most common problems in project reviews include: 1. Making the formula first and then deciding on the country of sale, resulting in the filter being declared unusable; 2. Using predicted values, raw material supplier data or old formula reports instead of finished product testing; 3. Only focusing on SPF, ignore UVA, light stability and actual film formation; 4. Continue to use the original report after changes in formula, packaging materials or processes; 5. Confusing U.S. OTC sunscreen with ordinary cosmetics labeling processes. These problems are often not that the technology is completely impossible, but that the key conditions are not frozen in advance.

For each high-risk item, six columns are established: probability of occurrence, impact, prevention, monitoring, correction, and responsible person. When deviations occur, isolate the affected batches and versions first, and then investigate the cause to avoid using the next round of samples to cover up the previous round of problems.

• The formula is made first and then the country of sale is decided, resulting in the filter being declared unusable.
• Replace finished product testing with predicted values, raw material supplier data, or old recipe reports
• Just follow SPF, ignore UVA, photostability and actual film formation
• Continue to use the original report after changes in formula, packaging materials or processes
• Confusing U.S. OTC sunscreen with ordinary cosmetics labeling process

9. What attachments should be included in procurement and contracts?

The contract attachments must at least quote: 1. Market access and filter list verification; 2. Formula, process, and test sample chain; 3.SPF/UVA/ Water resistance and original laboratory report; 4. Stability, packaging material and microbiological information; 5. Label claim approval and change records. When third-party packaging materials, raw materials or testing are involved, brand approval, supplier responsibilities, data delivery, change notifications and post-expiration handling must also be clearly stated.

The delivery terms should define the starting point, brand feedback suspension, supplier extension, retesting, force majeure and release mechanism; the acceptance terms should define the method, sample, objection period, re-inspection and non-conformity disposal.

10. Implementation suggestions for brands

A more reliable way to implement it is: 1. Determine the main sales market before the first round of proofing, and do not make up for compliance at the end; 2.SPF Goals should be written as development goals, not untested guaranteed values; 3. Reserve rounds of failed retests and recipe fine-tuning to avoid putting the activity date on the first report. Turning each suggestion into a person responsible and a date takes the step from reading the guide to project management.

YOU MIRACLE It is recommended that brands complete a one-page project brief before entering samples and quotations. The clearer the information, the more accurately factories can evaluate formulas, packaging materials, testing,MOQ and delivery time; when the information is unclear, the lowest quotation is usually the most difficult to use as the final cost.

• Determine the main sales market before the first round of proofing, and do not make up for compliance at the end
• put SPF Goals are written as development goals, not as untested guaranteed values.
• Reserve rounds of failed retests and recipe fine-tuning to avoid placing activity dates on the first report
