Dr. Bronner's Pure-Castile Liquid Soap Refill — Eucalyptus 32 oz, Concentrated Vegan & Regenerative Oils

Dr. Bronner's Eucalyptus Pure-Castile Liquid Refill is a concentrated, plant-based soap made from regenerative organic oils that cleans skin, hair, clothes, dishes and surfaces with a fresh eucalyptus scent.

This 32-ounce refill carton contains Dr. Bronner's classic Pure-Castile liquid formula scented with eucalyptus and designed to be diluted for many household and personal uses. The blend is vegan, non-GMO, and formulated from over 70% certified organic and fair-trade ingredients, now featuring regenerative organic certified coconut, palm kernel, and olive oils. Offered in a refill carton that reduces plastic by 86% per quart, it aims to be practical, economical, and more sustainable than single-use plastic bottles.

How concentrated is this eucalyptus liquid and how should I dilute it?

The soap is roughly three times more concentrated than common liquid soaps, so a little goes a long way. Dilute according to the task: very light for handwashing, moderate for body and hair, and stronger mixes for laundry and heavy cleaning.

• Hand soap: 1 part soap to 10 parts water in a pump bottle
• Body and hair: 1 part soap to 8–12 parts water
• Dishwashing/mopping: 1 part soap to 20 parts water
• Laundry prewash: 1–2 tablespoons in a sink; adjust for machine loads

What ingredients are in the refill and why do they matter?

Dr. Bronner's Pure-Castile formula uses plant-based oils rather than synthetic detergents or thickeners. Ingredients are largely certified organic and fair trade, including regenerative organic certified coconut, olive, and palm kernel oils, offering a cleaner ingredient profile and more transparent sourcing.

• Over 70% certified organic and fair trade ingredients
• Regenerative organic certified coconut, olive, and palm kernel oils
• No synthetic thickeners, dyes, or foaming agents
• Vegan, non-GMO formulation with plant-based preservatives

Can I use this soap safely on skin, pets and fabrics?

The liquid is formulated as a versatile true soap suitable for skin, hair, pets and many fabric-care tasks when diluted appropriately. It rinses clean and produces a rich lather, but always patch-test on sensitive skin or delicate fabrics and avoid eye contact with pets during washing.

• Face and body: dilute for gentle cleansing; avoid full-strength application to eyes
• Pets: dilute and rinse thoroughly; monitor for skin sensitivity
• Fabrics: use measured doses for prewash; test colorfastness first
• Household surfaces: dilute for mopping and all-purpose cleaning

How does the refill carton support sustainability compared to bottles?

The 32-ounce refill carton uses significantly less plastic per quart versus standard plastic bottles, helping reduce single-use plastic waste. Using the refill to top up a reusable pump bottle or container multiplies the environmental benefit while keeping the concentrated formula efficient to ship and store.

• 86% less plastic per quart compared with typical plastic refill bottles
• Concentrated formula lowers shipping emissions per use
• Encourages reuse of smaller pump bottles and dispensers
• Made with certified organic and fair-trade ingredient commitments

Who this refill is for: Ideal for households that want a multi-purpose, plant-based cleaner with a fresh eucalyptus scent—people who prefer concentrated products, reduce plastic waste, and value certified organic and fair-trade sourcing. It's suited to those seeking a single, versatile soap for hands, body, hair, pet baths, dishes and light laundry, as well as anyone looking to refill reusable dispensers while keeping ingredient transparency and sustainability in mind.
