BEEF TALLOW FAT
Beef Tallow is a major raw material used in the production of chemical intermediate products, such as fatty acids and fat alcohols. In addition to its principal uses in edible fats and oils, beef tallow is also used as baking and cooking fat, as well as in margarine production, which involves small amounts. With its similar fatty acid spectrum, beef tallow was formerly used to stretch cocoa butter.

No colour, no fragrance and definitely NO SLS, SLES, Parabens or Phthalates. We hate nasty chemicals here!!!

Unfragranced and totally natural. Superfat level of around 6-8% which means that there is plenty of the fabulous beef tallow left in the bar after use to moisturise and nourish your skin. Did you know that Beef tallow has been found to be the closest substance to human skin with regard to it's kindness, the nutrients it can provide and it's overall benefits? It hydrates even better than plant based products!

Beef Tallow (used for Animal feed & Industrial)
