Liquid Castile Gel Soap
Handmade in New Zealand
Thick natural soap base | 100% vegan | No synthetic surfactants or preservatives
Our Liquid Castile Gel Soap is the latest innovation in our Castile soap range. It is thicker, more versatile, and ready for customisation. Handmade in Aotearoa using a traditional soap base enhanced with modern surfactant science, this base combines the gentle cleansing power of potassium olivate and potassium cocoate (anionic surfactants) with coco glucoside, a mild, non-ionic surfactant derived from coconut.
Unlike the original Castile soaps of centuries past, our formula includes coconut oil to complement the olive oil, boosting foaming and surfactant activity. This makes it especially effective for laundry and cleaning applications, while still remaining gentle enough for sensitive skin.
Why You'll Love It:
- Thicker than classic liquid Castile soap – ideal for those wanting a richer, gel-like base
- Great for DIY hand soap, as well as shampoo, body wash, and household cleaning products
- No added salt – thick as-is, but can be diluted and thickened with a salt solution if desired
- No preservatives, sulphates, synthetic chelators, propylene glycol or ethanol
- pH (7 - 8) is lower than commercial laundry powders – ideal for delicate and sensitive skin
- Made in New Zealand using 100% natural ingredients
- Complies with Natural Products Association (NPA) and vegan certification standards
Made for Makers
This gel base is ideal for small-scale producers and DIY formulators.

It’s an economical base that doesn’t include expensive additives—giving you full control over your final formulation.
Start with a small test batch before scaling to ensure you’re happy with the viscosity. Some essential oils may thicken or thin the product.
