How we read the register

Updated 21 October 2026

Every therapeutic sunscreen sold in Australia has an entry on the Australian Register of Therapeutic Goods, and an AUST L number on its label that matches. Each entry has a public summary from the TGA that lists the active ingredients and how much of each is in the product. That summary is our only source for the figures in the table.

What we do

We find every entry with a UV filter among its actives, using the TGA’s ARTG search.
We read each one’s public summary. We keep only products that claim an SPF or a sunscreen indication, that are active, and that aren’t made for export only.
We turn each amount into a percentage by weight: 100 mg/g is 10%. A few entries give mg per mL, which can’t be turned into a percentage by weight without the density, so we show those as listed.
We compare the percentages of homosalate, oxybenzone and 4-MBC with each option the TGA has published, word for word from its consultation papers.
We read the whole register again every month, and record new entries and changed formulas on the changes page.

What we guess, and how to correct it

Two of the proposed homosalate options only cover face and hand sunscreens, and one only adult ones. The register doesn’t say who a product is for, so we read it from the name: “kids”, “baby” and “toddler” mean children; “face”, “tinted” and “BB” mean the face. A product we read wrongly can show “depends on use” where it shouldn’t. Email hello@sunscreenfilters.com with the ARTG number and we’ll fix it.

What we don’t do

We don’t test products, rate them or say which is safer. Every sunscreen on the register met the TGA’s rules when it was listed.
We don’t host the TGA’s documents. Each product page links to its own ARTG entry, where you can read the summary.
No maker pays to be in the table or to be placed higher.
