About the ingredients

I use only natural ingredients for all my products to ensure mild, safe, and predictable results. I use no animal products and do no animal testing.

(Text below each ingredient identifies what Irwin's Authentic product(s) contain this ingredient.)

Olive oil

I use olive oil extensively in Irwin's Authentic products. Historically known as a healing oil, it is especially soothing to the skin. Olive oil contains protein, minerals, and vitamins. It penetrates easily and while giving protection it allows the skin to breath naturally unlike many synthetic or petroleum products. Olive oil produces a high quality, hard bar of soap that is mild and cleans well. Olive oil acts as a humectant, attracting and retaining moisture.
