How to substitute shark squalene, step by step

  1. 1

    Pick the right substitute for the job

    For most recipes use Olive-derived squalane — serums and moisturisers. If you need a different texture, Sugarcane squalane works for sustainable, identical molecule.

  2. 2

    Measure using the correct ratio

    1:1. Weigh rather than eyeball it — small errors show up much faster when replacing shark squalene.

  3. 3

    Adjust the method

    The plant version is chemically identical and is now the industry standard — check the INCI ends in '-ane'.

  4. 4

    Taste and correct

    Plant swaps are usually a little less salty and less rich than shark squalene. Season at the end and add acid (lemon, vinegar) or umami (miso, nutritional yeast) if the dish tastes flat.

Mistakes to avoid

  • Swapping by volume when the recipe measures shark squalene by weight — check the ratio above first.
  • Using a sweetened or flavoured version in a savoury recipe.
  • Ignoring the method change: The plant version is chemically identical and is now the industry standard — check the INCI ends in '-ane'.
  • Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.
