  • Stearic acid from tallow?

    Posted by Margaret on March 8, 2023 at 5:31 pm

    Does anyone have any idea why it’s very hard, if maybe even NOT possible to get stearic acid that’s derived from beef tallow (a waste product)?

    I had asked about this from a re-packer & was told “You would be the ONLY one buying it”.

    Does this have everything to do with wanting to have a plant-derived product instead of animal derived?

    Probably cost…and by product channels. Animal fats…are going to head directly to the dog and cat food companies. So the stearic people will look for a less competitive source. Think…cost, Cost, COST…they will always go to the cheapest source of feedstock. Slaughter houses…generally don’t have a trash can….every part gets used. 🙂

    Most manufacturers probably stopped making products like this when there was an outbreak of mad cow disease in the 90’s.

    Depending on where you live there may even be import regulations around tallow. I am in Australia and we had one product that used a tallow based fabric softener and overnight the manufacturer stopped supplying it due to changes in the regulations for tallow based products.

    I thought mad cow disease was caused by prions found in the brain & spinal cord. Meh. What do I know?

    They are caused by that but in the cosmetic industry if something has even the hint of a problem, they’ll get rid of it if it’s easy to replace .
