With the implementation of GB 43631—2023 (Disposable Sanitary Wipes), China’s wipes industry has entered a new phase of regulatory refinement and technical standardization.

For overseas OEM wipes manufacturers supplying to China—or working with Chinese brands—this standard is more than a compliance update. It directly affects:

Liquid formulation design

Raw material selection

Microbial control systems

Safety validation procedures

Documentation and traceability

Understanding how GB 43631—2023 impacts wipe liquid systems is essential for maintaining market access and long-term competitiveness.

1. Why GB 43631—2023 Matters for OEM Manufacturers

Unlike previous fragmented guidelines, GB 43631—2023 establishes clearer requirements for:

Microbiological limits

Restricted and prohibited substances

Skin irritation and safety assessment

pH control

Labeling and claims compliance

For OEM factories, this means shifting from basic production capability to fully documented, risk-controlled formulation systems.

Low-cost, loosely validated formulations may no longer meet regulatory expectations or brand audit standards.

2. Direct Impact on Wipes Liquid Formulations

Since the liquid phase determines over 80% of wipes performance and safety, the new standard significantly raises technical requirements in formulation design.

2.1 Microbial Control Becomes a Strategic Priority

Manufacturers must ensure:

Controlled initial microbial load in bulk liquid

Effective preservative systems

Verified preservation efficacy (Challenge Test recommended)

Hygienic production environment validation

A weak preservative system can result in:

Finished product microbial failure

Microbial growth during storage

Increased customer complaints and recall risks

Forward-looking OEMs are shifting from single-preservative systems to multi-component preservation strategies combined with stability validation.

2.2 pH and Skin Compatibility Requirements

The standard emphasizes skin safety and mildness.

Recommended formulation direction:

Maintain pH between 5.0–6.5

Avoid high-alkaline cleaning systems

Evaluate irritation potential, especially for baby or sensitive-skin wipes

Many traditional “high-cleaning-power” formulas rely on elevated pH levels. Under GB 43631—2023, this approach increases regulatory and consumer risk exposure.

Balancing cleansing efficiency with dermatological compatibility is now essential.

2.3 Antibacterial and Disinfecting Wipes: Higher Compliance Threshold

If wipes are marketed with antibacterial or disinfecting claims:

Active ingredient dosage must comply with regulatory limits

Efficacy testing must support claims

Labeling must align with approved functional scope

Aggressive marketing claims without technical validation will face increasing scrutiny.

For OEMs exporting to multiple markets, harmonizing compliance between GB standards and EU/US regulations becomes even more critical.

3. Structural Changes Required in OEM Factories

GB 43631—2023 is not only about product testing—it requires systemic upgrades.

3.1 Raw Material Qualification System

OEM factories should establish:

Internal restricted substance lists

Supplier qualification and annual documentation updates

Full traceability for surfactants, preservatives, fragrances, and functional additives

Transparent raw material documentation is now a competitive advantage during brand audits.

3.2 Formula Documentation and Change Management

Recommended practices include:

Controlled formulation version management

Risk assessment for any ingredient change

Stability and compatibility validation after adjustments

Uncontrolled formula modifications can expose OEMs to compliance and liability risks.

3.3 Routine Validation and Testing

Forward-thinking OEMs integrate:

Regular microbiological testing

Stability studies

Skin compatibility assessments

Preservative efficacy (challenge testing)

Compliance must begin at the R&D stage—not after mass production.

4. The Relationship Between Regulation and Liquid Formulation

Regulations define the boundaries.
Formulation design defines performance within those boundaries.

Under GB 43631—2023, successful OEM manufacturers will:

Design safer yet effective surfactant systems

Optimize mild preservative strategies

Improve long-term formula stability

Provide transparent compliance documentation

Cost-driven formulation shortcuts are increasingly unsustainable.

Technical capability is becoming the core competitive factor.

5. Market Opportunities for Advanced OEM Manufacturers

While stricter standards may seem challenging, they also create opportunities:

Elimination of low-quality competitors

Increased demand for premium and sensitive-skin wipes

Greater brand reliance on technically strong OEM partners

Stronger global positioning through regulatory alignment

Brands are actively seeking OEM factories that can provide:

✔ Formulation risk assessment
✔ Regulatory-compliant liquid systems
✔ Microbial control expertise
✔ Technical documentation support

OEM manufacturers who invest in formulation science and compliance infrastructure will gain long-term strategic partnerships.

6. Conclusion: Compliance as a Growth Strategy

GB 43631—2023 is not merely a regulatory update—it is a transformation driver for the wipes industry.

For overseas OEM manufacturers, adapting early means:

Securing access to the Chinese market

Strengthening credibility with international brands

Reducing recall and compliance risks

Enhancing product differentiation

In today’s global wipes market, formulation science, safety validation, and regulatory transparency are no longer optional—they are fundamental.
