Why Olive Castile Soap Might Be the Best Thing You Can Use on Your Skin

Let’s take a moment for something beautifully simple: olive castile soap.

No perfumes. No unnecessary ingredients. Just one locally sourced plant oil — Australian olive oil — and a legacy of nourishing, skin-friendly care that’s lasted for centuries.

At The Australian Natural Soap Company, olive oil isn’t just an ingredient — it’s part of our foundation. And we still believe it might be the best thing you can use on your skin.

Castile soap has been around for a long time. Originally crafted in the Castile region of Spain, it became popular throughout the Mediterranean because of one simple fact: olive oil made the best soap.

Unlike animal-fat soaps or newer synthetic detergents, castile soap was plant-based, gentle, and effective. It cleansed without stripping, lathered beautifully, and was kind to even the most delicate skin.

The fact that it’s still around today — largely unchanged — says a lot. It’s stood the test of time because it works.

When I started The Australian Natural Soap Company, my goal wasn’t to make trendy skincare. I wanted to champion Australian plant oils.

At the time, I had started using macadamia oil on my own skin — a beautiful, local alternative to conventional moisturisers. So when we began making soap, that same philosophy guided our approach: keep it local, simple, and nourishing.

We experimented with different ingredients early on, but olive oil immediately stood out. It created a creamy, moisturising lather that felt gentle and soothing on the skin — without needing any additives.

That first bar made it clear: olive oil wasn’t just a base — it was the star.

So what makes olive oil such a powerhouse?

It’s packed with naturally skin-loving compounds, including:

And because it’s a single-ingredient soap (just saponified olive oil), there’s no clutter, no fillers, and no harsh chemicals. That makes it ideal for:

We offer our Olive Castile Soap in a few different formats — because what works for one person might look different for another.

Whichever format you choose, the formula is the same: just Australian olive oil, transformed into pure, nourishing soap.

Olive castile isn’t about hype. It’s not trying to be trendy. It’s not promising overnight miracles.

It’s just really good, honest skincare — the kind that respects your skin and supports it naturally.

In a world of 12-step routines and product overload, it’s a refreshing reminder that less really can be more.
