Foaming Castile Hand Soap Refill (2 oz.)

A simple refill, whenever you need it.

Already have your foaming bottle? This 2 oz. Foaming Castile Hand Soap Refill is designed to keep your routine going—without another plastic bottle in sight.

Made with our gentle, plant-based Castile soap, it creates a soft, effective foam that cleans thoroughly while remaining kind to skin. No synthetic detergents. No unnecessary fillers. Just simple ingredients that do the job well.

Each 2 oz. concentrate makes one full 12 oz. bottle of foaming hand soap.
Pour into your reusable bottle, top with water, and gently swirl to combine.

One refill = one full bottle of soap.
Simple. Practical. Low-waste.

Perfect for restocking your sink, trying a new scent, or keeping an extra on hand.

And because it’s true Castile soap, it isn’t limited to the sink.

This small bottle is great for travel—use a small amount in the shower, at the campsite, or by the kitchen sink when you’re away from home. A little goes a long way.

Each 2 oz. refill is a pre-measured portion of our concentrated Castile soap—designed to make refilling simple and consistent.
