Tag: Korean cosmetic labelling

🇰🇷 한국어판

Hello, this is Dr. J. Today we read the natural origin index printed on Korean cosmetic packaging — what that number counts, and why the words “Not a natural cosmetic” so often sit right beside it.

Two things surprise most people. In Korea, “natural cosmetic” is no longer defined in the law. And a product that misses the threshold can still print the index — the rules opened that door on purpose.

The primary sources

📄 Guide on Labelling and Advertising of Natural and Organic Cosmetics (Korea Cosmetic Association, PDF, Korean)

📄 Guideline on Labelling and Advertising of Cosmetics (MFDS, 14 Aug 2025, PDF, Korean)

📄 ISO 16128-2:2017 (abstract)

📄 U.S. FDA, “‘Organic’ Cosmetics”

The Korean documents carry the thresholds and the disclaimer wording; the ISO abstract carries the sentence that limits the standard itself.

――――――――――――――――――――――――――――

Five lines if you are in a hurry

✔ Korea deleted the legal definition of natural and organic cosmetics on 1 August 2025

✔ The thresholds now live in a 2025 industry guide: natural 95%, organic 10% plus natural 95%

✔ A product below the line may still print the index — with the calculation basis shown

✔ Beside that index the front panel carries “Not a natural cosmetic”

✔ ISO 16128 states that it does not address labelling, human safety or environmental safety

――――――――――――――――――――――――――――

The definition left the statute book in August 2025

Until 2025, Korean cosmetics law defined natural cosmetics and organic cosmetics and ran a government certification scheme for them. An amendment that took effect on 1 August 2025 deleted those definitions and the certification provisions together.

What filled the gap is not another statute. It is a guide published in 2025 by the Korea Cosmetic Association — more precisely by the advertising advisory committee of the self-regulatory review body for cosmetic labelling and advertising. The guide describes itself as setting out the minimum requirements for businesses that want to use these words.

※ The repeal itself, and the certification scheme that disappeared with it, were covered in Ingredient Guide 18. This article is about the number that is printed on packs now.

――――――――――――――――――――――――――――

What the guide counts — 95% and 10%

	What the guide says (translated)	How to read it
Natural cosmetic	A product whose natural and natural-origin content reaches 95% or more of the finished product by weight, calculated under the ISO 16128-2 guideline	The unit is the finished product, not an ingredient. Everything in the bottle is weighed
Organic cosmetic	Organic and organic-origin content of 10% or more of the finished product, with natural content — the organic part included — still at 95% or more	Both lines must hold. Organic is a branch of natural here, not an alternative route
What sits on the natural side	Plants and animals, minerals and micro-organisms, and ingredients derived from them	Not plants alone. Mineral and fermentation-derived materials belong here too
The calculation	ISO 16128-1 (definitions for ingredients) · ISO 16128-2 (criteria for ingredients and products)	A two-part international standard, borrowed as the arithmetic

――――――――――――――――――――――――――――

The guide’s scope reaches products that print only an index

This is the clause most summaries skip. The guide does not govern only products that call themselves natural. It also covers products that intend to print nothing but an ISO 16128 index.

Section of the guide	What it sets out
I. Purpose	To give consumers correct information and to set out the minimum requirements for businesses that label and advertise these words
II. Scope	Products labelled or advertised as natural or organic cosmetics, and products that calculate and print a natural or organic (origin) index under the ISO 16128 guideline
III. Criteria	1. Definitions · 2. Labelling and advertising · 3. Substantiation
Substantiation	A product that labels or advertises these words must be able to substantiate that it meets the criteria

――――――――――――――――――――――――――――

Blocked, then opened — the two sentences that explain the pack

Section III-2 of the guide places a prohibition and an exception side by side. Read apart, each one misleads; read together, they explain what you see on the shelf.

	What the guide says (translated)	In practice
The prohibition	Where the finished product does not meet the definition, the product may not directly label or advertise an ingredient as a natural (origin) or organic (origin) ingredient — even if that particular ingredient is one	One natural ingredient does not let the product speak of natural ingredients
The exception	However, where a natural (origin) or organic (origin) index calculated under the ISO 16128 guideline is presented clearly, together with the basis of the calculation, labelling and advertising by index is permitted	The number may be spoken. The calculation basis is the price of admission
The result on the pack	“Natural (origin) index 00% (calculated per ISO 16128)”	Exactly the string you find on Korean packaging

So “natural cosmetic” and “natural origin index” are two different claims. The first belongs to finished products above 95%; the second belongs to any product willing to show its arithmetic.

――――――――――――――――――――――――――――

What the MFDS guideline adds — the four permitted wordings

The Korean Ministry of Food and Drug Safety publishes a Guideline on Labelling and Advertising of Cosmetics (version of 14 August 2025). Its Annex 2, the table of claims that require substantiation, carries a dedicated row: “3. Content concerning ISO natural and organic index labelling and advertising.”

Permitted wording (as printed in the guideline)	Substantiation required
Natural index 00% (ISO 16128 calculation applied)	Substantiated by evidence relating to that finished product “In this case it is also necessary to indicate that the figure is calculated under the ISO 16128 guideline, together with wording that prevents consumer misunderstanding.”
Natural origin index 00% (ISO 16128 calculation applied)	same row
Organic index 00% (ISO 16128 calculation applied)	same row
Organic origin index 00% (ISO 16128 calculation applied)	same row

※ A footnote in the same annex defines the standard plainly: ISO 16128 is a method (guideline) for obtaining a calculated value for natural and organic content in cosmetics.

――――――――――――――――――――――――――――

Why “Not a natural cosmetic” sits beside the number

The guideline’s Section III, Notes is where this article’s hinge lies. When an ISO natural or organic index is labelled or advertised, the guideline says the following ways of writing it are to be followed to reduce consumer misunderstanding.

Where	What must appear alongside (translated)
① Front panel	“Not a natural cosmetic (organic cosmetic)”
② Elsewhere on the pack	“A simple calculation result under ISO 16128; does not mean the product falls under ‘natural cosmetic (organic cosmetic)’”
③ Media advertising	“Natural index 00% (a figure calculated under the ISO 16128 guideline). However, this figure does not mean the product qualifies as a natural (organic) cosmetic”

That small print on the front of the box is not a brand being modest. It is wording the guideline supplies, and the revision history shows when it arrived: the 30 December 2021 edition, recorded as “ISO natural and organic index labelling and advertising method established.”

――――――――――――――――――――――――――――

A prohibition with its own proviso

Annex 1 of the same guideline lists expressions that may not be used. One line reads:

The last clause carries the weight. The prohibition arrives with its exception attached. A product outside the thresholds cannot say “natural”, yet the index wording of Annex 2 item 3 is carved out of that ban — the same architecture as the guide’s “blocked, then opened” pair above.

――――――――――――――――――――――――――――

What the number does not count — six items, named by the standard itself

The ISO 16128-2 abstract contains one sentence that keeps this whole subject honest.

The index counts where ingredients came from. Whether a formula is gentle, whether it suits your skin, whether the packaging is sound — none of that is the standard’s business, and it says so.

Which leaves a gap, and the gap is the interesting part: a standard that refuses to speak about labelling is being used for labelling. Each market has filled that silence differently.

――――――――――――――――――――――――――――

One standard, three jobs — Korea, the EU and the United States

	Korea	European Union	United States
Legal definition of natural / organic	Deleted on 1 August 2025. The thresholds now sit in a 2025 industry guide	No definition in the Cosmetics Regulation	FDA does not define it — “The term ‘organic’ is not defined in either of these laws or the regulations that FDA enforces under their authority.”
Where the criteria live	Korea Cosmetic Association guide — natural 95% · organic 10% plus natural 95%	Regulation (EC) No 655/2013 and its six common criteria: legal compliance, truthfulness, evidential support, honesty, fairness, informed decision-making	For organic, the USDA National Organic Program — “The USDA requirements for the use of the term ‘organic’ are separate from the laws and regulations that FDA enforces for cosmetics.”
Status of ISO 16128	Named in the guide and the guideline as the calculation method	Not named in the Regulation	Not named
What must accompany an index	“Not a natural cosmetic (organic cosmetic)” on the front panel	No set wording; the claim must clear the common criteria — “If it is claimed on the product that it contains a specific ingredient, the ingredient shall be deliberately present.”	No set wording
Relationship to safety	Neither the guide nor the guideline is a safety standard	The common criteria govern advertising, not safety	FDA — “An ingredient’s source does not determine its safety.”

※ The six common criteria are the headings of the Annex to Regulation (EC) No 655/2013, applicable since 11 July 2013. Note what all three jurisdictions share: none of them treats a high natural index as a statement about safety.

――――――――――――――――――――――――――――

Four things to check on the box

✔ Look for a percentage next to the word “natural”, not the word alone

✔ Look for “calculated per ISO 16128” — the calculation basis is a condition, not decoration

✔ If you see “Not a natural cosmetic”, that is an index claim — the line is required, not a confession

✔ Judge gentleness from the ingredient list and concentrations, not from the index

――――――――――――――――――――――――――――

In one line

The natural origin index counts where ingredients came from; it does not measure how gentle a product is. Above 95% a product may be called a natural cosmetic; below it, the figure may still be printed with its calculation shown — and the words “Not a natural cosmetic” go with it.

What is not in this article, and why

✔ The calculation formula itself — ISO standards are paid documents. Only the published abstracts were read

✔ The ingredient categories of ISO 16128-1 — same reason; the standard text was not opened

✔ Article and clause numbers of the Enforcement Rule — Korea’s national law portal was unreachable on the day of writing, so no provision numbers are cited

✔ The approval date of the industry guide — the PDF yields only the year (2025)

✔ Certification bodies and marks — none appear in the guide’s text, so none are named here

✔ Claims that natural or organic means gentler — no primary source supports them. The ISO sentence above says the standard does not address human safety, which is the honest version of that question

Passages from the Korean guide and guideline are my translation of the Korean originals; the ISO and FDA sentences are quoted in their published English. Korea’s national law portal was unreachable on the day of writing, so statutory provisions were not re-opened, and ISO standard texts are paid documents, so only the published abstracts were used.
