General Principles：

We embed green and safety-first principles into our formula from the earliest stages of R&D. While fully complying with all applicable regulatory requirements, we go further by applying internal safety standards that exceed industry benchmarks to rigorously select every raw material. We uphold an unwavering commitment to “zero use and zero addition of prohibited substances”.

Moreover, for ingredients that are controversial or under safety monitoring, we adopt a precautionary approach—we establish internal safety guidelines and implementing rigorous safety assessment procedure to build a comprehensive safety management system that ensures controllable sourcing, manageable processes, and preventable risks. This system serves as a robust safeguard for product safety, delivering consumers a trustworthy and reassuring experience. Our approach is guided by the following three core principles:

I. “Regulatory Compliance as the Foundation, Enhanced by Internal Safety Assessment Guidelines"

We reference the following industry regulations and standards (this list is non-exhaustive and will be updated periodically in line with the latest laws and regulations):

(1) Domestic Regulations

● Hygienic requirements for disposable sanitary products

● Safety and Technical Standards for Cosmetics

● Technical Guidelines for Cosmetic Safety Assessment

● Regulations on the Safety Administration of Hazardous Chemicals

(2) International Regulations

● EU Cosmetics Regulation (EC) No. 1223/2009

● EU REACH Regulation

● California Proposition 65

● EU Biocidal Products Regulation (BPR) No. 528/2012

● Scientific Committee on Consumer Safety (SCCS) (EU)

● Cosmetic Ingredient Review (CIR) (US)

● Regulation (EC) No. 1272/2008 on the Classification, Labeling and Packaging of Substances and Mixtures (CLP Regulation)

● International Fragrance Association (IFRA) Standards

● Relevant Regulations of the Research Institute for Fragrance Materials (RIFM) (US)

To fundamentally raise the bar on product safety, we’ve developed internal safety assessment guidelines that are both stringent and industry-leading. These guidelines integrate safety controls throughout the entire product lifecycle—from raw materials to finished products to post-market monitoring—achieving a closed-loop management system that enables risk identification to continuous monitoring. Recognizing that different raw materials and product categories carry unique physical and chemical properties, application scenarios, and potential hazards, our assessment framework sets clear, tailored requirements for every stage of the process.

● Formula Governance: We begin collecting full formula documentation at the earliest stage of supplier engagement to ensure comprehensive access to fundamental ingredient information from the outset，laying a solid data foundation for subsequent safety assessments.

● Dual Screening for Regulatory Compliance and Risks: All ingredients and products undergo a two-tier screening process: first, for alignment with the latest domestic and international regulatory requirements to identify potential compliance gaps; and second, through toxicological data analysis to proactively assess safety risks—such as harmful by-products from ingredient interactions or contaminants introduced during manufacturing.

● Scientific Validation Through Testing: Develop customized testing matrix for identified risks—conducting third-party toxicological tests (e.g., skin irritation tests, sensitization tests) on high-risk raw materials/formulas and comprehensive safety tests on finished products.

● Stricter Internal Limits: While fully compliant with all applicable regulations, we set stricter internal limits aligned with our safety objectives to further reduce potential safety risks.

● Post-Marketing Monitoring: Regularly re-evaluate raw materials/finished products based on regulatory updates, technological advancements, and market feedback; after product launch, continuously monitor safety status. Should any new potential risk emerge, we will immediately trigger a reassessment and implement corrective actions as needed.

Based on referenced domestic and international standards and regulations—and guided by internal Safety Assessment Principles—we have established the Vinda Prohibited Substances List (see Appendix).

II. Principle of Rigorous Supplier Admission：

This principle is a strategic approach to safeguarding product safety, compliance, and quality at the source. By implementing a multi-dimensional, high-standard onboarding review process, we selectively partner with suppliers with solid compliance awareness and risk management capabilities—thereby proactively mitigating quality and compliance risks across the supply chain from the earliest R&D stages. The specific implementation dimensions are refined into the following three aspects, forming a closed-loop, end-to-end supplier assessment framework:

1. Factory Audit System

In addition to initial on-site factory audits, we conduct regular reviews of suppliers’ qualifications, raw material test reports, and other relevant documents. We also enforce rigorous incoming inspections for both raw materials and finished products. Through this multi-tiered verification process, we select partners who consistently deliver reliable product quality and uphold strong credibility.

2. Supplier Self-Inspection and Commitment System

Suppliers are required to confirm their compliance with Vinda’s prohibited substances policy and all applicable regulatory requirements through "proactive self-inspection + third-party verification". This creates a closed-loop management cycle of ‘self-inspection → verification → corrective actions’. We regularly update safety declarations based on domestic and international regulations as well as the latest scientific findings. These declarations include regulatory requirements and prohibited/restricted substance lists for suppliers to verify compliance, with suppliers committing that their materials/finished products:

a) Comply with all applicable regulations and standards;

b) Do not use prohibited substances listed;

c) Adhere to Vinda’s specified limits for restricted substances.

Suppliers are also required to sign a Safety Declaration, affirming the above commitments. Any concealment of information or false declaration shall constitute a material breach of contract, and the supplier will be held fully liable for all resulting legal and contractual consequences.

3. Formulation Integrity

Formulations are fundamental to product safety and quality. To proactively identify potential ingredient risks, we require suppliers to provide full, accurate, and transparent disclosure of all formulation details—addressed through the following three aspects:

▶ "Full Transparency" Formula Disclosure: Including full ingredient disclosure (including additives, fragrances, inks, etc.), along with detailed raw material specifications (e.g., purity, grade) and precise ingredient addition ratios. For compound or blended raw materials, a full breakdown of all substances is required to ensure end-to-end traceability of every material used in the product.

▶ Formula Safety Assessment: Our safety assessment team conducts risk assessments based on disclosed formula, intended use scenarios (e.g., food contact, oral, ocular, dermal, or mucosal exposure), applicable product standards, and internal assessment guidelines—all to ensure safety at the formulation stage.

Vinda’s risk assessment procedure references and adopts cosmetic safety evaluation procedure:

● Hazard Identification: Collect extensive, authoritative toxicological data from domestic and international sources—including key toxicological endpoints (e.g., acute toxicity, skin sensitization, carcinogenicity) and historical usage evidence—to determine the hazard profile and severity of raw materials and substances of concern.

● Dose-Response Assessment: Determine the relationship between the exposure and the toxic response

● Exposure Assessment: Exposure levels are evaluated by considering key factors such as the route of exposure, concentration, frequency, and duration of contact between raw materials (or substances of concern) and the human body.

● Risk Characterization: Describe the likelihood and severity of adverse health effects caused by raw materials/risk substances.

This risk assessment procedure improves the accuracy and reliability of assessment results and provides a scientific basis for designing testing matrix for each raw material.

▶ Formula Change Control Agreement: To prevent uncontrolled formula changes that could lead to product quality variations or compliance risks, suppliers are required to "notify in advance of formula changes." If a supplier needs to modify a formula due to raw material substitution, process optimization, manufacturing site relocation, etc., they must submit a formal change request accompanied by supporting validation documentation. This includes a comparative performance report (before and after the change) and updated safety test reports. Implementation of the proposed change is permitted only upon written approval from Vinda following a thorough review.

III. Standardized Testing Principle

Building on the above two principles, we have established an internal testing matrix combining Standard Test Items (STI) and Material-Specific Testing based on years of experience and domestic/international regulations, constructing another line of defense for safety.

● STI (Standard Test Items): Constitute a comprehensive testing checklist covering physicochemical parameters, chemical analyses, and toxicological tests. It is a list of prohibited and high-concern chemical substances established in accordance with regulatory and industry standards. Vinda’s safety assessment team rigorously adheres to this STI checklist to ensure that every material undergoes the required evaluations without exception.

● Material-Specific Testing: Given that raw materials vary significantly in origin, physicochemical properties, and manufacturing processes—each with unique potential risk substances introduced or generated during production—this customized testing matrix enables precise risk management. For example, pesticide residues are monitored for plant-derived raw materials, and allergens are prioritized for fragrance.

The STI and Material-Specific Testing matrix are not static. We have established a "dynamic update mechanism" to track the latest changes in domestic and international regulations, newly prohibited or restricted substances are promptly added to the STI list, which keeps the testing scope remains continuously aligned with regulatory requirements and optimizes test items and evaluation criteria.

In addition to stringent source control of raw material safety, we have implemented a comprehensive, high-standard compliance and safety assurance system for finished products. This ensures that every product undergoes rigorous pre-launch verification and fully complies with the regulatory requirements of its target markets.

Before any product reaches the market, it must pass a comprehensive release inspection conducted by our Quality Control team. The testing protocol fully aligns with national and industry regulations applicable to the product category—for example, disposable hygiene products are assessed against GB 15979 standards.

The evaluation covers critical dimensions including physicochemical performance and key safety parameters such as microbial limits, restricted/prohibited substance levels and pH, ensuring no product enters the supply chain without passing all required tests and obtaining a Product Qualification Certificate.

For products destined for international markets, we implement customized compliance protocols that go beyond baseline release testing. These are designed to address specific regulatory requirements of each target region—for example, additional screening for Substances of Very High Concern (SVHCs) under the EU REACH regulation，ensuring full conformity through supplementary testing and certification where needed.
