AICIS and Sunscreen: Where the Regulatory Line Sits

Someone building a tinted moisturizer with SPF for the Australian market asked me a fair question: if sunscreen is a drug and not a cosmetic, why does anyone even bring up AICIS when discussing it? The answer is that AICIS operates one level below the product-category question entirely, at the level of the chemical ingredients themselves, and that layer applies whether the finished product ends up classified as a therapeutic good or a cosmetic.

Two different questions, easy to conflate

The first question is: what is this finished product, a cosmetic or a therapeutic good? In most markets, including the general pattern that applies in Australia, a product making a sun protection claim, actually functioning to protect skin from UV radiation, is treated as a therapeutic good rather than an ordinary cosmetic, similar to how sunscreen is regulated as an OTC drug rather than a cosmetic in some other markets. That classification decision sits with the therapeutic goods framework, not with AICIS.

The second question, entirely separate, is: are the industrial chemicals used to make this product, whatever its final classification, properly introduced under the Australian Industrial Chemicals Introduction Scheme? AICIS regulates industrial chemicals, including many ingredients that end up in both cosmetics and therapeutic goods, through its Inventory and introduction categories. A UV filter chemical does not stop being an industrial chemical for AICIS purposes just because the finished product built around it gets classified as a therapeutic good rather than a cosmetic.

Why both regimes end up touching the same ingredient

Take a common organic UV filter used in a sunscreen formula. That chemical:

• Needs to be a legitimate, appropriately introduced industrial chemical under AICIS, whether it ends up in a cosmetic-classified product or a therapeutic good.
• Separately needs to satisfy whatever therapeutic goods framework applies to sunscreen actives specifically, which is a distinct and generally more rigorous approval pathway than the AICIS introduction process alone.

So a formulator working on a sunscreen in Australia is not choosing between AICIS and the therapeutic goods framework. Both apply, to different aspects of the same product, because they are answering different regulatory questions.

Where this gets confusing in practice

The confusion mostly comes from assuming that because sunscreen is "not a cosmetic," cosmetic-adjacent regulatory tools like AICIS have nothing to say about it. That is backwards. AICIS is not a cosmetic-specific scheme in the way Health Canada's Cosmetic Notification System is. It is a chemical-introduction scheme that happens to cover a large share of cosmetic ingredients simply because most cosmetic ingredients are, chemically speaking, industrial chemicals. Sunscreen actives fall into that same broad chemical universe even while the finished sunscreen product sits under a different, separate finished-product regime.

A practical way to think about it

Layer	What it governs	Applies to sunscreen?
Therapeutic goods framework	Whether the finished product's UV protection claim is permitted, and under what conditions	Yes, this is usually the primary regime for a genuine sunscreen claim
AICIS	Whether the chemical ingredients (UV filters, emulsifiers, preservatives) are properly introduced into Australian commerce	Yes, at the ingredient level, regardless of finished product classification

What this means for your formula

If you are building a tinted moisturizer, a daily moisturizer with SPF, or a standalone sunscreen for the Australian market, do not treat the "is this a cosmetic" question as the only regulatory question you need answered. Even after you have settled that a sun protection claim moves your product into the therapeutic goods lane, every industrial chemical in that formula, from the UV filter to the humble preservative system, still needs to check out under AICIS.

That layered reality, where ingredient-level and product-level obligations run in parallel rather than one replacing the other, is exactly the kind of thing worth mapping out before formulation rather than after. Cosmetic Comply's ingredient-level matching and screening approach is built with that layered structure in mind as Australia support develops, alongside the Canadian notification system already live today.
