Castile Soap in Australia – Natural, Unscented & Everyday Low-Tox Cleaning

Castile soap is one of the most versatile natural cleaners available, made by saponifying plant oils such as olive and coconut into a gentle, biodegradable soap. Unlike synthetic detergents or sulphate-based body washes, true Castile soap contains no SLS/SLES, petrochemical surfactants or artificial fragrance—making it suitable for sensitive skin, baby items and low-tox home cleaning.

This collection features unscented, lightly scented and solid Castile soaps ideal for body care, hand washing, dishes, laundry, and DIY multi-purpose cleaning blends. Whether you're switching to fragrance-free products, reducing chemical load in your home, or looking for a simple all-in-one cleaner, these plant-oil formulas deliver reliable performance with minimal ingredients.
