ISO 16128: Complete Guide to International Natural Cosmetics Standards

ISO 16128 provides international standards for calculating and verifying naturalness percentages in cosmetic products, enabling brands to make transparent claims like "95% natural origin" while ensuring global compliance and consumer trust.

What is ISO 16128 and Why Do You Need It?

ISO 16128 is an international standard that establishes unified rules for determining "naturalness" in cosmetic products. When you see "95% natural origin (ISO 16128)" on a cream package, it means the manufacturer calculated the percentage of natural ingredients using strict international formulas.

This standard has become the global benchmark for natural cosmetics claims, providing transparency and consistency across different markets and brands.

Key Components of ISO 16128 Standard

ISO 16128 consists of two interconnected parts that work together to define and calculate naturalness:

Part	Publication Year	Content	Status
ISO 16128-1	2016	Definitions and ingredient categories	Confirmed in 2022
ISO 16128-2	2017	Formulas for calculating naturalness indexes	Confirmed in 2023 with 2022 amendment

Why ISO 16128 Was Created: Solving Industry Problems

Before ISO 16128, each country and organization interpreted "natural cosmetics" differently, creating confusion for manufacturers and consumers. The standard solved three key problems:

1. Terminology Unification

• Global consistency: "Natural cream" now means the same thing in Australia and Germany
• Standardized definitions: Clear categories for natural, organic, and derived ingredients
• Reduced market confusion: Consumers can compare products across brands and regions

2. Simplified International Trade

• One calculation for all markets: No need to adapt formulas for different regional requirements
• Streamlined compliance: Single methodology recognized worldwide
• Faster market entry: Reduced regulatory barriers for international expansion

3. Greenwashing Protection

• Transparent formulas: Strict calculation methods prevent inflated naturalness claims
• Objective standards: Consumers can trust that declared percentages are accurate
• Comparable results: Fair competition based on standardized metrics

Who Developed ISO 16128 and When Was It Adopted?

The standard was developed by ISO Technical Committee 217 "Cosmetics", which includes experts from over 40 countries. The development process considered input from:

• Cosmetics manufacturers
• Raw material suppliers
• Certification bodies
• Consumer organizations
• Regulatory authorities

Timeline of Adoption

• February 2016: Publication of Part 1 (ISO 16128-1)
• September 2017: Publication of Part 2 (ISO 16128-2)
• 2022: Amendment to Part 2 released
• 2022-2023: Confirmation of both parts' relevance

Key Requirements of ISO 16128 Standard

Ingredient Categories and Classifications

ISO 16128 divides all cosmetic ingredients into clearly defined categories:

Category	Description	Index
Natural ingredient	Raw materials from nature without chemical modification (water, honey, plant oils)	NI = 1
Derived natural ingredient	Natural raw materials after acceptable chemical processing	NOI > 0.5
Organic ingredient	Natural raw materials with organic certification	OI = 1
Derived organic ingredient	Organic raw materials after chemical processing	OOI > 0.5
Mineral ingredient	Mineral raw materials (water, salt, clay)	NI = 1

Acceptable Processing Methods

The standard only allows "green chemistry" processes: hydrolysis, esterification, transesterification, amidation, hydrogenation, other reactions without adding/removing carbon atoms

ISO 16128 Calculation Formula

The percentage of naturalness is calculated using this formula:

% Naturalness = Σ (ingredient mass × its index) / total product mass

Similar calculations apply to organic ingredient indexes (OI, OOI).

Example ISO 16128 Calculation

For a 100g cream containing:

• 70g water (NI = 1)
• 20g derived natural oil (NOI = 0.8)
• 10g synthetic preservative (NI = 0)

Natural origin percentage = (70×1 + 20×0.8 + 10×0) / 100 = 86%

How to Obtain ISO 16128 Compliance Certification

Two Methods of Compliance Verification

1. Self-Declaration of Conformity (SDoC)

What it is: The company performs all calculations and documentation internally without external verification.

Advantages of Self-Declaration:

• Low costs: No need for independent audits or certification fees
• Fast implementation: Quicker process without waiting for external reviews
• Full process control: Company sets internal timelines and calculation formats

Disadvantages:

• Requires internal expertise: Need qualified specialists in standardization and chemical analysis
• Less consumer trust: Lack of independent verification may raise doubts among consumers and retailers

2. Third-Party Certification

What it is: An independent accredited organization audits ISO 16128 calculations, reviews documentation, and issues an official compliance certificate.

Major Certification Bodies:

• SGS: Global leader in testing, inspection, and certification services
• Ecocert: French certification organization specializing in organic and natural cosmetics
• Intertek: British FTSE 100 company providing independent testing and certification
• TÜV: German technical inspection associations (TÜV Nord, TÜV Rheinland, TÜV SÜD)
• CCPB: Italian inspection and certification body for organic products
• Cosmacon: German consulting company specializing in ISO 16128 certification

Required Documentation for ISO 16128 Compliance

Mandatory Documents

• Complete formula with exact percentages: Required for calculating natural and organic indexes
• Raw material specifications from suppliers: Detailed documentation of origin, composition, and characteristics
• Safety Data Sheets (SDS) for all ingredients: Risk assessments and safety information
• Index calculations (NI/NOI/OI/OOI): Following ISO 16128 methodology
• Organic origin certificates (if applicable): Official documentation for certified organic ingredients

Recommended Documents

• ISO 22716 GMP Certificate: Good Manufacturing Practice compliance
• Laboratory Certificates of Analysis (CoA): Test results for each raw material batch
• Label mockup mentioning ISO 16128: Marketing materials showing compliance claims

Audit Procedure for ISO 16128 Compliance

Step-by-Step Process

1. Application submission: Submit application and documentation package to auditor
2. Contract conclusion: Define scope of work and certification costs
3. Document review: Auditor checks calculations and standard compliance
4. Additional requests: Clarify disputed points and address findings
5. Certificate issuance: Receive compliance documentation
