Mineral Sunscreens Deceive: Cheaper Dupes Offer Same Protection

New research from UNSW has revealed that Australian consumers may be overpaying for "mineral" sunscreens. Testing of popular brands indicated that "natural" formulations, often containing zinc oxide, frequently include undisclosed chemical filters found in cheaper alternatives. These chemical ingredients significantly contribute to the advertised sun protection factor (SPF), challenging the "mineral-only" marketing claims.

The study found that over a third of TGA-registered mineral sunscreens contained unregulated chemical filters, such as butyloctyl salicylate, which boost SPF performance. Some cosmetic-classified sunscreens avoid TGA registration and ingredient disclosure altogether. This practice allows brands to market products with hidden active ingredients, potentially deceiving consumers seeking specific formulations.

This UNSW investigation follows a previous scandal prompted by consumer advocacy group Choice. The Therapeutic Goods Administration (TGA) is now reviewing its sunscreen regulations, including the testing methods used, to address these findings and ensure greater transparency and consumer safety in the Australian sunscreen market.
