Cosmetic manufacturers and product developers in Izmir Turkey may need to demonstrate how they classify natural and organic ingredients and calculate the natural-origin or organic content of their formulations. ISO 16128 provides guidelines that help establish a consistent approach to these calculations.
The standard is particularly relevant to skincare, personal-care, and other cosmetic formulations that use plant-derived, mineral, or other ingredients classified under its framework. It can help technical teams organize ingredient information, document calculation methods, and support substantiation of product composition claims.
ISO 16128 is not, by itself, a universal certification for finished cosmetics or pharmaceutical products. It also does not replace applicable product-safety, labelling, or regulatory requirements. Businesses should confirm which standards and legal obligations apply to their products before making natural or organic claims.
PopularCert can assist businesses with understanding the applicable framework, reviewing ingredient documentation, and organizing the calculations and supporting records required for their chosen compliance approach.

Understanding ISO 16128: Natural and Organic Cosmetic Ingredients
ISO 16128 is a two-part guideline developed for the cosmetics sector. Its purpose is to establish definitions and a consistent framework for assessing natural, natural-origin, organic, and organic-origin ingredients and products.
- ISO 16128-1:2016 – Definitions for ingredients: Establishes definitions and categories used to classify cosmetic ingredients, including natural and organic ingredients.
- ISO 16128-2:2017 – Criteria for ingredients and products: Provides approaches for calculating natural, natural-origin, organic, and organic-origin indexes and content.
Part 2 should be read alongside Part 1. Businesses need appropriate ingredient information and a documented calculation method to apply the framework to a formulation. The standard does not independently verify every supplier claim or establish that a product is safe for use.
For cosmetics manufacturers in Izmir, the practical starting point is to review ingredient specifications, identify the relevant ingredient categories, and determine how the composition calculations will be documented and reviewed.
How ISO 16128 Applies to Cosmetic Manufacturers in Izmir
ISO 16128 can help cosmetic businesses use a consistent method to classify ingredients and assess the composition of their formulations. Its practical value depends on the quality of the ingredient data and the way the calculation process is implemented.
Cosmetic manufacturers: Use ingredient classifications and documented calculations when reviewing the composition of skincare, personal-care, and other cosmetic products.
Formulation and research teams: Maintain traceable ingredient specifications and document the assumptions used to calculate natural-origin and organic content.
Ingredient suppliers and distributors: Provide clear technical information to help customers understand the classification and composition of supplied materials.
Quality and regulatory teams: Review whether composition calculations are supported by suitable records and whether any resulting product claims comply with the applicable labelling and regulatory requirements.
For businesses in Izmir, these activities can be incorporated into existing formulation development, supplier review, and product documentation processes. ISO 16128 should be used for its intended scope rather than treated as a replacement for a complete cosmetic compliance programme.

Example: Reviewing Natural-Origin Content in a Cosmetic Formulation
Consider a cosmetic manufacturer developing a facial cream with several ingredients supplied by different vendors. The formulation team wants to calculate its natural-origin content using ISO 16128.
The team first collects the relevant ingredient specifications and supporting information from suppliers. It then classifies the ingredients using the applicable ISO 16128 definitions, determines the relevant indexes and contribution values, and applies the calculation method specified by Part 2. The team documents the input data, assumptions, calculation results, and review process.
If supplier information is incomplete or a classification cannot be substantiated, the team should resolve the uncertainty before relying on the calculated result in product communications.
This is an illustrative workflow, not a calculation for a real product. Actual percentages depend on the formulation, ingredient data, and applicable calculation method. A natural-origin percentage should not be presented as an organic percentage unless the relevant organic criteria and calculation support that conclusion.
Benefits of ISO Certification for Government Services, Education & Research
ISO 16128 provides a structured way for cosmetic businesses to describe and calculate natural and organic ingredient content. When applied with suitable supporting data, it can help teams make their formulation records more consistent and easier to review.
- Consistent ingredient classification: Apply defined terminology instead of relying on informal interpretations of “natural” or “organic.”
- Documented composition calculations: Keep calculation methods, source data, and results together for technical review.
- Improved supplier information management: Identify gaps in ingredient specifications and request additional supporting evidence when needed.
- Better formulation review: Give product development and quality teams a common basis for reviewing composition information.
- More substantiated product communications: Use documented composition information as one input when evaluating claims, while checking applicable labelling and regulatory requirements separately.
These benefits depend on the quality of the source data and the implementation process. Following ISO 16128 does not automatically establish product safety, guarantee regulatory approval, or entitle a business to use a certification mark.
Difference Table: ISO-Certified vs Non-Certified Organizations (Government Services, Education & Research)
Topic | ISO 16128 guidance | Product certification or regulatory approval |
|---|---|---|
Main purpose | Defines and calculates natural and organic cosmetic ingredient/product content | Depends on the specific certification scheme or legal regime |
Main evidence | Ingredient classifications, supplier data, and calculation records | Evidence and assessments required by the applicable scheme or authority |
Product safety | Does not independently establish safety | Depends on the relevant safety requirements and assessment |
Labelling and claims | Does not independently authorize claims | Depends on applicable labelling laws and claim requirements |
Outcome | A documented method for describing composition | A certificate, approval, or other formal outcome only where the relevant scheme provides for it |
How Popularcert Can Help Government Services, Education & Research
Cosmetic manufacturers and ingredient suppliers may need support interpreting ISO 16128, organizing formulation records, and reviewing how natural-origin or organic content is calculated.
PopularCert can provide consulting support in areas such as:
-
Scope review: Identify which parts of ISO 16128 are relevant to the products and formulation activities under review.
-
Ingredient documentation: Review available specifications and identify missing information that may affect classification or calculations.
-
Calculation support: Help organize the data, methods, and records used to determine relevant natural-origin and organic content indexes.
-
Documentation review: Check whether calculation records and supporting evidence are clear, traceable, and consistently maintained.
-
Claims-readiness review: Help identify composition statements that require further substantiation or a separate regulatory review.
The work required will depend on the formulation, the available supplier data, and the client’s intended use of the results. Any formal certification or regulatory approval must be obtained through the appropriate applicable route; PopularCert consulting support should not be described as a guarantee of either outcome.
How to Calculate Natural-Origin Content Under ISO 16128
Cosmetic manufacturers need more than an ingredient list to substantiate natural-origin content. They need suitable supplier information, a consistent classification method, and calculations that can be reviewed and traced back to the formulation.
For a manufacturer in Izmir developing a facial cream, the process can begin with the following steps:
- Collect ingredient information
Record each ingredient’s identity, quantity in the formulation, supplier specifications, and the information needed to determine its classification under ISO 16128.
- Determine the applicable ingredient indexes
Use the relevant definitions and criteria in ISO 16128-1 and ISO 16128-2 to determine the appropriate natural-origin or organic indexes. Do not assume that every plant-derived ingredient automatically qualifies as organic.
- Calculate the formulation’s natural-origin content
Apply the relevant calculation method to the formulation data. For an illustrative simplified calculation, suppose a 100 kg formulation contains ingredients with a combined natural-origin contribution of 72 kg under the applicable calculation method. The resulting natural-origin content would be 72%.
This example is hypothetical. Actual calculations must use the appropriate ISO 16128 method, ingredient indexes, and formulation data. The mass of plant-derived ingredients alone is not sufficient to establish the result.
- Maintain supporting records
Keep the formulation version, supplier documentation, ingredient classifications, calculation worksheet, assumptions, and review records together. Update the calculation when the formulation or relevant ingredient information changes.
- Review product claims separately
A natural-origin calculation does not automatically prove that a product is organic, safe, or compliant with all labelling requirements. Review the intended claim against the applicable regulatory and substantiation requirements before publishing it.
For cosmetics businesses in Izmir, this process can help make ingredient calculations more consistent and provide a clearer evidence trail for technical and quality reviews.
Applying ISO 16128 to Cosmetic Formulations in Izmir
ISO 16128 offers cosmetic manufacturers a consistent framework for classifying natural and organic ingredients and calculating relevant composition indexes. Its practical value depends on accurate ingredient information, a suitable calculation method, and records that support the results.
Businesses should also distinguish these calculations from product-safety assessments, labelling obligations, and any separate certification or regulatory approval that may apply to their products.
PopularCert can help businesses review their documentation needs and identify the next steps for applying the framework to relevant formulations.
