What an Australian cosmetic ingredients list does and does not tell you

What the Australian rules cover

Cosmetic ingredient labelling in Australia sits under a Consumer Goods Information Standard listed on the Federal Register of Legislation as the Consumer Goods (Cosmetics) Information Standard 2020. Its operative sections are headed 'List of ingredients' and 'Form of ingredients list', and it also carries provisions on confidentiality, review of decisions and additional requirements for hand sanitisers. The register records the instrument as effective from 24 November 2020 and running to 11 pages.

That is a standard about presentation. It determines that a list must be there and the form it takes; it does not require the amount of any ingredient to be stated, and it does not assess whether a formula works.

The ingredients themselves are regulated a long way upstream. The Industrial Chemicals Act 2019 establishes the Australian Industrial Chemicals Introduction Scheme, and requires that introductions of industrial chemicals be authorised, through listed, exempted, reported, assessed, commercial evaluation or exceptional circumstances pathways. Almost every ingredient in a skincare product is an industrial chemical for this purpose, including the ones described as natural.

Reading order without reading too much into it

Ingredient lists are conventionally written in descending order of amount, which gives you a ranking and not a scale. Knowing that one ingredient appears above another tells you nothing about whether the gap is 2% or 40%.

Water is the first entry on most leave-on and rinse-off products, and that is not a criticism of the formula. What is worth noticing is where the named, marketed ingredient sits. An ingredient listed after the preservatives and fragrance is present in a small amount, because preservatives are themselves used at low levels.

The practical reading is therefore structural rather than quantitative. Look at the first five entries to understand what the product mostly is, look at where the headline ingredient sits relative to the preservatives, and treat everything else on the pack as marketing.

• The first five entries describe what the product mostly is
• An ingredient listed after the preservatives is present at a low level
• Order gives a ranking, never a percentage
• A long list is not evidence of complexity and a short one is not evidence of purity
• The same ingredient can appear under different names, so compare lists rather than front-of-pack claims

A patch test is the only test you can actually run

No label tells you whether your skin tolerates a formula, and no price does either. The method that does is a patch test, and it costs nothing beyond 5 days of patience and a pea of product.

Apply a small amount to the same 2 centimetre area of the inner forearm once a day for 5 days running, and leave the area alone otherwise. Reactions that appear on day one are usually irritation; reactions that appear on day three or later are the reason the test runs for 5 days rather than one. If nothing happens, repeat the same procedure on a small area beside the jaw for a further 5 days before committing to the full face.

Run the test before opening a premium product rather than after. A $140 jar abandoned halfway costs $2.80 for each of the 50 applications made, against $1.40 for a jar finished, which makes the 10 days of testing the cheapest part of the whole purchase.

1. Choose one new product at a time, never two
2. Apply a small amount to the same 2 centimetre patch on the inner forearm once a day for 5 days
3. Record what you see each day rather than relying on memory
4. If nothing happens, repeat for 5 days on a small area beside the jaw
5. Introduce the product to the full routine only after those 10 days
6. Stop immediately if the skin breaks, which is a medical question rather than a buying one

What to do with all of this at the shelf

Photograph the ingredients list of anything you already tolerate. That photograph is the most useful document in this whole exercise, because it lets you compare a new product against a known one rather than against a theory.

When two products are being compared, read the first five entries of each and the position of the headline ingredient relative to the preservatives. Then convert both to a cost per use, because a product you tolerate at $0.40 an application and one you tolerate at $1.40 are a $730 a year decision on a 50 mL jar used twice daily.

Finally, keep the receipt. Australian consumer guarantees apply automatically to products bought from a business trading in Australia, and Consumer Affairs Victoria states the consumer threshold as products costing up to $100,000, with $40,000 applying before 1 July 2021. A product that is not of acceptable quality is a guarantee question, not a goodwill one.

Before you buy

• Photograph the ingredients list of a product you already tolerate
• Read the first five entries to see what a new product mostly is
• Note where the marketed ingredient sits relative to the preservatives
• Treat ingredient order as a ranking, never as a percentage
• Patch test one new product at a time for 5 days on the forearm
• Repeat for 5 days beside the jaw before full-face use
• Convert both candidates to a cost per use before choosing

Questions readers ask

Does an Australian label have to show ingredient percentages?

No. The Consumer Goods (Cosmetics) Information Standard 2020 has sections headed 'List of ingredients' and 'Form of ingredients list', which govern that a list appears and the form it takes. No concentration is required, so two products naming the same ingredient can contain very different amounts of it and both comply fully.

Are natural or organic ingredients regulated differently?

Not under the chemicals scheme. The Industrial Chemicals Act 2019 requires introductions of industrial chemicals to be authorised regardless of origin, through one of six pathways including listed, exempted and assessed introductions. Plant extracts and oils are introduced under the same framework as synthesised ingredients.

How long should a patch test run?

Five days on the inner forearm, then a further 5 days beside the jaw before the product joins the routine. A one-day test only catches immediate irritation. Running it over 5 days catches the slower responses, and testing one product at a time is what makes the result interpretable.

Why does water appear first on almost everything?

Because lists are written in descending order of amount and most leave-on products are mostly water. It carries no quality signal either way. What is informative is where the marketed ingredient sits, particularly whether it appears before or after the preservatives, which are themselves used at low levels.

What happens if a product I bought is faulty?

The automatic consumer guarantees apply to products bought from a business trading in Australia, with the consumer threshold set at products costing up to $100,000. Acceptable quality is one of those guarantees, and the remedy sits with the seller. Keep the receipt and a photograph of the pack as it arrived.
