  • Austrailian Gold SPF - Anhydrous?

    Posted by TheSocksTooBig on August 25, 2022 at 5:45 pm

    Hello everyone, 

    I was wondering if the austrailian gold spf is an anhydrous formula. Does anyone have experience using Alumina at such a high level?

    Active Ingredients

    • Titanium Dioxide 4%
    • Zinc Oxide 4% Sunscreen

    Inactive Ingredients

    Alumina, Butyrospermum Parkii (Shea) Butter, Caprylyl Glycol, Cetyl PEG/PPG-10/1 Dimethicone, Cyclopentasiloxane, Dimethicone Crosspolymer, Disodium EDTA, Disteardimonium Hectorite, Eucalyptus Globulus Leaf Extract, Glycerin, Hexyl Laurate, Iron Oxides, Panthenol, PEG-10 Dimethicone, Phenoxyethanol, Polyglyceryl-4 Isostearate, Polymethylsilsesquioxane, Porphyra Umbilicalis (Red Algae) Extract, Silica, Squalane, Stearic Acid, Terminalia Ferdinandiana (Kakadu Plum) Fruit Extract, Tocopheryl Acetate*, Triethoxycaprylylsilane, Water

    *Vitamin E

    It contains water so it is not anhydrous.
    Sunscreen is classified as a drug in the US and it has different labelling requirements compared to cosmetics. The inactive ingredients are listed in alphabetical order and not by concentration. You will not be able to determine the amount used from the ingredients list.

    Hi I had a little look at some formulations available on another Chemist Forum and it seems from my research (and by no means do I have the particular answers I though looking at these formulations may help you decide approx % for what is in the product you are looking at - but I think if you are a home formulator you would have little chance of sourcing all the ingredients - Anyway here are a few formulations for a Liquid Foundation, and a sunscreen w/o emulsion to view. I personally would not attempt to make a sunscreen even for myself - but out of interest check these out and see if it helps your question. Sorry have to do this in 2 sections as cant get 2nd table to work otherwise when I cut and paste. BTW I think the Alumina is part of a belnd that you would buy like this one which one formulation had at 25% of the total

    This is mislabeled.  As both a drug and cosmetic, inactive ingredients must be offered in descending order by content - not in alphabetical order.

    @TheSocksTooBig @Squinny is right. Alumina usually comes as a blend with TiO2 as a stabilizer, to reduce its catalytic potential.
