How to substitute tallow soap, step by step
- 1
Pick the right substitute for the job
For most recipes use Olive oil castile soap — body and hands. If you need a different texture, Coconut-palm free bar soap works for everyday.
- 2
Measure using the correct ratio
1:1. Weigh rather than eyeball it — small errors show up much faster when replacing tallow soap.
- 3
Adjust the method
'Sodium tallowate' on a soap label means beef fat — it's the single most common hidden animal ingredient in bar soap.

Taste and correct
Plant swaps are usually a little less salty and less rich than tallow soap. 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 tallow soap by weight — check the ratio above first.
- Using a sweetened or flavoured version in a savoury recipe.
- Ignoring the method change: 'Sodium tallowate' on a soap label means beef fat — it's the single most common hidden animal ingredient in bar soap.
- Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.

Check the evidence before choosing
Vegan ingredients, cruelty-free testing policies and environmental claims answer different questions. Check the exact product and its market, not just the brand name or a badge on the front of the pack.
Compare price per serving or use, the full ingredient list and any certification in the certifier’s own directory. Missing evidence means the claim is unconfirmed; it does not automatically mean the product fails.
- A practical example
- For a plant milk, compare protein and fortification alongside price per litre. For skincare, check ingredients and animal-testing policy separately.
- What to keep in mind
- Formulas, prices and certification can change. A ranking is a starting point for comparison, not a guarantee or an independent laboratory test.
